# firejail-profile

## NAME



           profile - Security profile file syntax, and information about
           building new application profiles.
    


## SYNOPSIS



           Using a specific profile:
    
                  **firejail --profile=filename.profile**
    
                         Example:
                         $ firejail --appimage
                         --profile=/etc/firejail/kdenlive.profile
                         kdenlive.appimage
    
                  **firejail --profile=profile_name**
    
                         Example:
                         $ firejail --appimage --profile=kdenlive
                         kdenlive.appimage
    
           Building a profile manually:
    
                  Start with the template in
                  /usr/share/doc/firejail/profile.template and modify it in a
                  text editor.  To integrate the program in your desktop
                  environment copy the profile file in ~/.config/firejail
                  directory and run "sudo firecfg".
    
           Aliases and redirections:
    
                  In some cases the same profile can be used for several
                  applications.  One such example is LibreOffice.  Build a
                  regular profile for the main application, and for the rest
                  use /usr/share/doc/firejail/redirect_alias-
                  profile.template.
    
           Running the profile builder:
    
                  **firejail --build=appname.profile appname**
    
                         Example:
                         $ firejail --build=blobby.profile blobby
    
                         Run the program in "firejail --build" and try to
                         exercise as many program features as possible.  The
                         profile is extracted and saved in the current
                         directory. Open it in a text editor and add or
                         remove sandboxing options as necessary. Test again
                         after modifying the profile. To integrate the
                         program in your desktop environment copy the profile
                         file in ~/.config/firejail directory and run "sudo
                         firecfg".
    


## DESCRIPTION



           Several command line options can be passed to the program using
           profile files. Firejail chooses the profile file as follows:
    
           **1.** If a profile file is provided by the user with --profile
           option, the profile file is loaded. If a profile name is given, it
           is searched for first in the ~/.config/firejail directory and if
           not found then in /etc/firejail directory. Profile names do not
           include the .profile suffix.  Example:
    
                  $ firejail --profile=/home/netblue/icecat.profile icecat
                  Reading profile /home/netblue/icecat.profile
                  [...]
    
                  $ firejail --profile=icecat icecat-wrapper.sh
                  Reading profile /etc/firejail/icecat.profile
                  [...]
    
           **2.** If a profile file with the same name as the application is
           present in ~/.config/firejail directory or in /etc/firejail, the
           profile is loaded. ~/.config/firejail takes precedence over
           /etc/firejail. Example:
    
                  $ firejail icecat
                  Command name #icecat#
                  Found icecat profile in /home/netblue/.config/firejail
                  directory
                  Reading profile
                  /home/netblue/.config/firejail/icecat.profile
                  [...]
    
           **3.** Use a default.profile file if the sandbox is started by a
           regular user, or a server.profile file if the sandbox is started
           by root. Firejail looks for these files in ~/.config/firejail
           directory, followed by /etc/firejail directory.  To disable
           default profile loading, use --noprofile command option. Example:
    
                  $ firejail
                  Reading profile /etc/firejail/default.profile
                  Parent pid 8553, child pid 8554
                  Child process initialized
                  [...]
    
                  $ firejail --noprofile
                  Parent pid 8553, child pid 8554
                  Child process initialized
                  [...]
    


## Templates



           In /usr/share/doc/firejail there are two templates to write new
           profiles.
                  profile.template - for regular profiles
                  redirect_alias-profile.template - for aliasing/redirecting
                  profiles
    


## Scripting



           Scripting commands:
    
           **File and directory names**
                  File and directory names containing spaces are supported.
                  The space character ' ' should not be escaped.
    
                  Example: "blacklist ~/My Virtual Machines"
    
           **# this is a comment**
                  Example:
    
                  # disable networking
                  net none # this command creates an empty network namespace
    
           **?CONDITIONAL: profile line**
                  Conditionally add profile line.
    
                  Example: "?HAS_APPIMAGE: whitelist
                  ${HOME}/special/appimage/dir"
    
                  This example will load the whitelist profile line only if
                  the --appimage option has been specified on the command
                  line.
    
                  Currently the only conditionals supported this way are
                  HAS_APPIMAGE, HAS_NET, HAS_NODBUS, HAS_NOSOUND, HAS_PRIVATE
                  and HAS_X11. The conditionals ALLOW_TRAY,
                  BROWSER_DISABLE_U2F and BROWSER_ALLOW_DRM can be enabled or
                  disabled globally in Firejail's configuration file.
    
                  The profile line may be any profile line that you would
                  normally use in a profile **except** for "quiet" and "include"
                  lines.
    
                  Note: When using one or more conditionals and **--profile** , it
                  is recommended that the relevant option(s) (such as
                  **--appimage**) be specified before **--profile** , so that their
                  respective conditional(s) (such as **?HAS_APPIMAGE**) inside of
                  the profile evaluate to true.
    
           **include other.profile**
                  Include other.profile file.
    
                  Example: "include /etc/firejail/disable-common.inc"
    
                  The file name can be prefixed with a macro such as ${HOME}
                  or ${CFG}.  ${HOME} is expanded as user home directory, and
                  ${CFG} is expanded as Firejail system configuration
                  directory - in most cases /etc/firejail or
                  /usr/local/etc/firejail.
    
                  Example: "include ${HOME}/myprofiles/profile1" will load
                  "~/myprofiles/profile1" file.
    
                  Example: "include ${CFG}/firefox.profile" will load
                  "/etc/firejail/firefox.profile" file.
    
                  The file name may also be just the name without the leading
                  directory components.  In this case, first the user config
                  directory (${HOME}/.config/firejail) is searched for the
                  file name and if not found then the system configuration
                  directory is search for the file name.  Note: Unlike the
                  --profile option which takes a profile name without the
                  '.profile' suffix, include must be given the full file
                  name.
    
                  Example: "include firefox.profile" will load
                  "${HOME}/.config/firejail/firefox.profile" file and if it
                  does not exist "${CFG}/firefox.profile" will be loaded.
    
                  System configuration files in ${CFG} are overwritten during
                  software installation.  Persistent configuration at system
                  level is handled in ".local" files. For every profile file
                  in ${CFG} directory, the user can create a corresponding
                  .local file storing modifications to the persistent
                  configuration. Persistent .local files are included at the
                  start of regular profile files.
    
           **noblacklist file_name**
                  If the file name matches file_name, the file will not be
                  blacklisted in any blacklist commands that follow.
    
                  Example: "noblacklist ${HOME}/.mozilla"
    
           **nowhitelist file_name**
                  If the file name matches file_name, the file will not be
                  whitelisted in any whitelist commands that follow.
    
                  Example: "nowhitelist ~/.config"
    
           **ignore** Ignore command.
    
                  Example: "ignore seccomp"
                  Example: "ignore net eth0"
    
           **quiet** Disable Firejail's output. This should be the first
                  uncommented command in the profile file.
    
                  Example: "quiet"
    


## Filesystem



           These profile entries define a chroot filesystem built on top of
           the existing host filesystem. Each line describes a file/directory
           that is inaccessible (**blacklist**), a read-only file or directory
           (**read-only**), a tmpfs mounted on top of an existing directory
           (**tmpfs**), or mount-bind a directory or file on top of another
           directory or file (**bind**).  Use **private** to set private mode.  File
           globbing is supported, and PATH and HOME directories are searched,
           see the **firejail FILE GLOBBING** section for more details.
           Examples:
    
           **blacklist file_or_directory**
                  Blacklist directory or file. Examples:
    
                  blacklist /usr/bin
                  blacklist /usr/bin/gcc*
                  blacklist ${PATH}/ifconfig
                  blacklist ${HOME}/.ssh
    
           **blacklist-nolog file_or_directory**
                  When --tracelog flag is set, blacklisting generates syslog
                  messages if the sandbox tries to access the file or
                  directory.  blacklist-nolog command disables syslog
                  messages for this particular file or directory. Examples:
    
                  blacklist-nolog /usr/bin
                  blacklist-nolog /usr/bin/gcc*
    
           **bind directory1,directory2**
                  Mount-bind directory1 on top of directory2. This option is
                  only available when running as root.
    
           **bind file1,file2**
                  Mount-bind file1 on top of file2. This option is only
                  available when running as root.
    
           **disable-mnt**
                  Disable /mnt, /media, /run/mount and /run/media access.
    
           **keep-config-pulse**
                  Disable automatic ~/.config/pulse init, for complex setups
                  such as remote pulse servers or non-standard socket paths.
    
           **keep-dev-shm**
                  /dev/shm directory is untouched (even with private-dev).
    
           **keep-shell-rc**
                  Do not copy shell rc files (such as ~/.bashrc and ~/.zshrc)
                  from /etc/skel.
    
           **keep-var-tmp**
                  /var/tmp directory is untouched.
    
           **mkdir directory**
                  Create a directory in user home, under /tmp, or under
                  /run/user/<UID> before the sandbox is started.  The
                  directory is created if it doesn't already exist.
    
                  Use this command for whitelisted directories you need to
                  preserve when the sandbox is closed. Without it, the
                  application will create the directory, and the directory
                  will be deleted when the sandbox is closed. Subdirectories
                  are recursively created. Example from firefox profile:
    
                  mkdir ~/.mozilla
                  whitelist ~/.mozilla
                  mkdir ~/.cache/mozilla/firefox
                  whitelist ~/.cache/mozilla/firefox
    
                  For files in /run/user/<PID> use ${RUNUSER} macro:
    
                  mkdir ${RUNUSER}/firejail-testing
    
           **mkfile file**
                  Similar to mkdir, this command creates an empty file in
                  user home, or /tmp, or under /run/user/<UID> before the
                  sandbox is started. The file is created if it doesn't
                  already exist.
    
           **noexec file_or_directory**
                  Remount the file or the directory noexec, nodev and nosuid.
    
           **private**
                  Mount new /root and /home/user directories in temporary
                  filesystems. All modifications are discarded when the
                  sandbox is closed.
    
           **private directory**
                  Use directory as user home.  --private and
                  --private=directory cannot be used together.
    
                  Bug: Even with this enabled, some commands (such as mkdir,
                  mkfile and private-cache) will still operate on the
                  original home directory.  Workaround: Disable the
                  incompatible commands, such as by using "ignore mkdir" and
                  "ignore mkfile".  For details, see #903 
                  ⟨https://github.com/netblue30/firejail/issues/903⟩
    
           **private-bin file,file**
                  Build a new /bin in a temporary filesystem, and copy the
                  programs in the list.  The files in the list must be
                  expressed as relative to the /bin, /sbin, /usr/bin,
                  /usr/sbin, or /usr/local/bin directories.  The same
                  directory is also bind-mounted over /sbin, /usr/bin and
                  /usr/sbin.  Multiple private-bin commands are allowed and
                  they accumulate.
    
           **private-cache**
                  Mount an empty temporary filesystem on top of the .cache
                  directory in user home. All modifications are discarded
                  when the sandbox is closed.
    
           **private-cwd**
                  Set working directory inside jail to the home directory,
                  and failing that, the root directory.
    
           **private-cwd directory**
                  Set working directory inside the jail. Full directory path
                  is required. Symbolic links are not allowed.
    
           **private-dev**
                  Create a new /dev directory. Only disc, dri, dvb, hidraw,
                  null, full, zero, tty, pts, ptmx, random, snd, urandom,
                  video, log, shm and usb devices are available.  Use the
                  options no3d, nodvd, nosound, notv, nou2f and novideo for
                  additional restrictions.
    
           **private-etc file,directory**
                  Build a new /etc in a temporary filesystem, and copy the
                  files and directories in the list.  The files and
                  directories in the list must be expressed as relative to
                  the /etc directory, and must not contain the / character
                  (e.g., /etc/foo must be expressed as foo, but /etc/foo/bar
                  -- expressed as foo/bar -- is disallowed).  All
                  modifications are discarded when the sandbox is closed.
                  Multiple private-etc commands are allowed and they
                  accumulate.
    
           **private-home file,directory**
                  Build a new user home in a temporary filesystem, and copy
                  the files and directories in the list in the new home.  The
                  files and directories in the list must be expressed as
                  relative to the current user's home directory.  All
                  modifications are discarded when the sandbox is closed.
    
           **private-opt file,directory**
                  Build a new /opt in a temporary filesystem, and copy the
                  files and directories in the list.  The files and
                  directories in the list must be expressed as relative to
                  the /opt directory, and must not contain the / character
                  (e.g., /opt/foo must be expressed as foo, but /opt/foo/bar
                  -- expressed as foo/bar -- is disallowed).  All
                  modifications are discarded when the sandbox is closed.
    
           **private-srv file,directory**
                  Build a new /srv in a temporary filesystem, and copy the
                  files and directories in the list.  The files and
                  directories in the list must be expressed as relative to
                  the /srv directory, and must not contain the / character
                  (e.g., /srv/foo must be expressed as foo, but /srv/foo/bar
                  -- expressed as foo/bar -- is disallowed).  All
                  modifications are discarded when the sandbox is closed.
    
           **private-tmp**
                  Mount an empty temporary filesystem on top of /tmp
                  directory whitelisting /tmp/.X11-unix.
    
           **read-only file_or_directory**
                  Make directory or file read-only.
    
           **read-write file_or_directory**
                  Make directory or file read-write.
    
           **tmpfs directory**
                  Mount an empty tmpfs filesystem on top of directory.
                  Directories outside user home or not owned by the user are
                  not allowed. Sandboxes running as root are exempt from
                  these restrictions.
    
           **tracelog**
                  Blacklist violations logged to syslog.
    
           **whitelist file_or_directory**
                  Whitelist directory or file. A temporary file system is
                  mounted on the top directory, and the whitelisted files are
                  mount-binded inside. Modifications to whitelisted files are
                  persistent, everything else is discarded when the sandbox
                  is closed. The top directory can be all directories in /
                  (except /proc and /sys), /sys/module, /run/user/$UID, $HOME
                  and all directories in /usr.
    
                  Symbolic link handling: with the exception of user home,
                  both the link and the real file should be in the same top
                  directory. For user home, both the link and the real file
                  should be owned by the user.
    
           **whitelist-ro file_or_directory**
                  Equivalent to "whitelist file_or_directory" followed by
                  "read-only file_or_directory"
    
           **writable-etc**
                  Mount /etc directory read-write.
    
           **writable-run-user**
                  Disable the default blacklisting of run/user/$UID/systemd
                  and /run/user/$UID/gnupg.
    
           **writable-var**
                  Mount /var directory read-write.
    
           **writable-var-log**
                  Use the real /var/log directory, not a clone. By default, a
                  tmpfs is mounted on top of /var/log directory, and a
                  skeleton filesystem is created based on the original
                  /var/log.
    


## Security filters



           The following security filters are currently implemented:
    
           **allow-debuggers**
                  Allow tools such as strace and gdb inside the sandbox by
                  whitelisting system calls ptrace and process_vm_readv.
    
           **caps** Enable default Linux capabilities filter.  See
                  capabilities(7) for details.
    
           **caps.drop capability,capability,capability**
                  Blacklist given Linux capabilities.
    
           **caps.drop all**
                  Blacklist all Linux capabilities.
    
           **caps.keep capability,capability,capability**
                  Whitelist given Linux capabilities.
    
           **memory-deny-write-execute**
                  Install a seccomp filter to block attempts to create memory
                  mappings that are both writable and executable, to change
                  mappings to be executable or to create executable shared
                  memory.
    
           **nonewprivs**
                  Sets the NO_NEW_PRIVS prctl.  This ensures that child
                  processes cannot acquire new privileges using execve(2);
                  in particular, this means that calling a suid binary (or
                  one with file capabilities) does not result in an increase
                  of privilege.
    
           **noprinters**
                  Disable printers.
    
           **noroot** Use this command to enable an user namespace. The namespace
                  has only one user, the current user.  There is no root
                  account (uid 0) defined in the namespace.
    
           **protocol protocol1,protocol2,protocol3**
                  Enable protocol filter. The filter is based on seccomp and
                  checks the first argument to socket system call. Recognized
                  values: **unix** , **inet** , **inet6** , **netlink** , **packet** , and **bluetooth**.
                  Multiple protocol commands are allowed and they accumulate.
    
           **restrict-namespaces**
                  Install a seccomp filter that blocks attempts to create new
                  cgroup, ipc, net, mount, pid, time, user or uts namespaces.
    
           **restrict-namespaces cgroup,ipc,net,mnt,pid,time,user,uts**
                  Install a seccomp filter that blocks attempts to create any
                  of the specified namespaces.
    
           **seccomp**
                  Enable seccomp filter and blacklist the syscalls in the
                  default list. See man 1 firejail for more details.
    
           **seccomp.32**
                  Enable seccomp filter and blacklist the syscalls in the
                  default list for 32 bit system calls on a 64 bit
                  architecture system.
    
           **seccomp syscall,syscall,syscall**
                  Enable seccomp filter and blacklist the system calls in the
                  list on top of default seccomp filter.
    
           **seccomp.32 syscall,syscall,syscall**
                  Enable seccomp filter and blacklist the system calls in the
                  list on top of default seccomp filter for 32 bit system
                  calls on a 64 bit architecture system.
    
           **seccomp.block-secondary**
                  Enable seccomp filter and filter system call architectures
                  so that only the native architecture is allowed.
    
           **seccomp.drop syscall,syscall,syscall**
                  Enable seccomp filter and blacklist the system calls in the
                  list.
    
           **seccomp.32.drop syscall,syscall,syscall**
                  Enable seccomp filter and blacklist the system calls in the
                  list for 32 bit system calls on a 64 bit architecture
                  system.
    
           **seccomp.keep syscall,syscall,syscall**
                  Enable seccomp filter and whitelist the system calls in the
                  list.
    
           **seccomp.32.keep syscall,syscall,syscall**
                  Enable seccomp filter and whitelist the system calls in the
                  list for 32 bit system calls on a 64 bit architecture
                  system.
    
           **seccomp-error-action kill | log | ERRNO**
                  Return a different error instead of EPERM to the process,
                  kill it when an attempt is made to call a blocked system
                  call, or allow but log the attempt.
    
           **x11** Enable X11 sandboxing.
    
           **x11 none**
                  Blacklist /tmp/.X11-unix directory, ${HOME}/.Xauthority and
                  file specified in ${XAUTHORITY} environment variable.
                  Remove DISPLAY and XAUTHORITY environment variables.  Stop
                  with error message if X11 abstract socket will be
                  accessible in jail.
    
           **x11 xephyr**

           **x11 xpra**
                  Enable X11 sandboxing with Xpra server.
    
           **x11 xvfb**
                  Enable X11 sandboxing with Xvfb server.
    
           **xephyr-screen WIDTHxHEIGHT**
                  Set screen size for x11 xephyr. This command should be
                  included in the profile file before x11 xephyr command.
    
                  Example:
    
                  xephyr-screen 640x480
                  x11 xephyr
    


## DBus filtering



           Access to the session and system DBus UNIX sockets can be allowed,
           filtered or disabled. To disable the abstract sockets (and force
           applications to use the filtered UNIX socket) you would need to
           request a new network namespace using --net command. Another
           option is to remove unix from the --protocol set.
    
           Filtering requires installing the xdg-dbus-proxy utility. Filter
           rules can be specified for well-known DBus names, but they are
           also propagated to the owning unique name, too. The permissions
           are "sticky" and are kept even if the corresponding well-known
           name is released (however, applications rarely release well-known
           names in practice). Names may have a .* suffix to match all names
           underneath them, including themselves (e.g. "foo.bar.*" matches
           "foo.bar", "foo.bar.baz" and "foo.bar.baz.quux", but not
           "foobar"). For more information, see xdg-dbus-proxy(1).
    
           Examples:
    
           **dbus-system filter**
                  Enable filtered access to the system DBus. Filters can be
                  specified with the dbus-system.talk and dbus-system.own
                  commands.
    
           **dbus-system none**
                  Disable access to the system DBus. Once access is disabled,
                  it cannot be relaxed to filtering.
    
           **dbus-system.own org.gnome.ghex.***
                  Allow the application to own the name org.gnome.ghex and

                  path /org/freedesktop/Notifications by the client owning
                  the bus name org.freedesktop.Notifications on the system
                  DBus.
    
           **dbus-system.broadcast**
           **org.freedesktop.Notifications=org.freedesktop.Notifications.*@/org/freedesktop/Notifications**
                  Allow the application to receive broadcast signals from the
                  interface org.freedesktop.Notifications of the object
                  exposed at the path /org/freedesktop/Notifications by the
                  client owning the bus name org.freedesktop.Notifications on
                  the system DBus.
    
           **dbus-user filter**
                  Enable filtered access to the session DBus. Filters can be
                  specified with the dbus-user.talk and dbus-user.own
                  commands.
    
           **dbus-user none**
                  Disable access to the session DBus. Once access is
                  disabled, it cannot be relaxed to filtering.
    
           **dbus-user.own org.gnome.ghex.***
                  Allow the application to own the name org.gnome.ghex and
                  all names underneath in on the session DBus.
    
           **dbus-user.talk org.freedesktop.Notifications**

                  path /org/freedesktop/Notifications by the client owning
                  the bus name org.freedesktop.Notifications on the session
                  DBus.
    
           **dbus-user.broadcast**
           **org.freedesktop.Notifications=org.freedesktop.Notifications.*@/org/freedesktop/Notifications**

                  exposed at the path /org/freedesktop/Notifications by the
                  client owning the bus name org.freedesktop.Notifications on
                  the session DBus.
    
           **nodbus**(deprecated)
                  Disable D-Bus access (both system and session buses).
                  Equivalent to dbus-system none and dbus-user none.
    
           Individual filters can be overridden via the --ignore command.
           Supposing a profile has
                  [...]
                  dbus-user filter
                  dbus-user.own org.mozilla.firefox.*
                  dbus-user.talk org.freedesktop.Notifications
                  dbus-system none
                  [...]
    
                  and the user wants to disable notifications, this can be
                  achieved by putting the below in a local override file:
                  [...]
                  ignore dbus-user.talk org.freedesktop.Notifications
                  [...]
    


## Resource limits, CPU affinity



           These profile entries define the limits on system resources
           (rlimits) for the processes inside the sandbox.  The limits can be
           modified inside the sandbox using the regular **ulimit** command. **cpu**
           command configures the CPU cores available.
    
           Examples:
    
           **cpu 0,1,2**
                  Use only CPU cores 0, 1 and 2.
    
           **nice -5**
                  Set a nice value of -5 to all processes running inside the
                  sandbox.
    
           **rlimit-as 123456789012**

                  123456789012 bytes.
    
           **rlimit-cpu 123**
                  Set the maximum CPU time in seconds.
    
           **rlimit-fsize 1024**
                  Set the maximum file size that can be created by a process
                  to 1024 bytes.
    
           **rlimit-nproc 1000**
                  Set the maximum number of processes that can be created for
                  the real user ID of the calling process to 1000.
    
           **rlimit-nofile 500**
                  Set the maximum number of files that can be opened by a
                  process to 500.
    
           **rlimit-sigpending 200**
                  Set the maximum number of processes that can be created for
                  the real user ID of the calling process to 200.
    
           **timeout hh:mm:ss**
                  Kill the sandbox automatically after the time has elapsed.
                  The time is specified in hours/minutes/seconds format.
    


## User Environment



           **allusers**
                  All user home directories are visible inside the sandbox.
                  By default, only current user home directory is visible.
    
           **env name=value**
                  Set environment variable. Examples:
    
                  env LD_LIBRARY_PATH=/opt/test/lib
                  env CFLAGS="-W -Wall -Werror"

## Networking



           Networking features available in profile files.
    
           **defaultgw address**
                  Use this address as default gateway in the new network
                  namespace.
    
           **dns address**
                  Set a DNS server for the sandbox. Up to three DNS servers
                  can be defined.
    
           **hostname name**
                  Set a hostname for the sandbox.
    
           **hosts-file file**
                  Use file as /etc/hosts.
    
           **ip address**
                  Assign IP addresses to the last network interface defined
                  by a net command. A default gateway is assigned by default.
    
                  Example:
                  net eth0
                  ip 10.10.20.56
    
           **ip none**
                  No IP address and no default gateway are configured for the
                  last interface defined by a net command. Use this option in
                  case you intend to start an external DHCP client in the
                  sandbox.
    
                  Example:
                  net eth0
                  ip none
    
           **ip dhcp**
                  Acquire an IP address and default gateway for the last
                  interface defined by a net command, as well as set the DNS
                  servers according to the DHCP response.  This command
                  requires the ISC dhclient DHCP client to be installed and
                  will start it automatically inside the sandbox.
    
                  Example:
                  net br0
                  ip dhcp
    
                  This command should not be used in conjunction with the dns
                  command if the DHCP server is set to configure DNS servers
                  for the clients, because the manually specified DNS servers
                  will be overwritten.
    
                  The DHCP client will NOT release the DHCP lease when the
                  sandbox terminates.  If your DHCP server requires leases to
                  be explicitly released, consider running a DHCP client and
                  releasing the lease manually in conjunction with the net
                  none command.
    
           **ip6 address**
                  Assign IPv6 addresses to the last network interface defined
                  by a net command.
    
                  Example:
                  net eth0
                  ip6 2001:0db8:0:f101::1/64
    
           **ip6 dhcp**
                  Acquire an IPv6 address and default gateway for the last
                  interface defined by a net command, as well as set the DNS
                  servers according to the DHCP response.  This command
                  requires the ISC dhclient DHCP client to be installed and
                  will start it automatically inside the sandbox.
    
                  Example:
                  net br0
                  ip6 dhcp
    
                  This command should not be used in conjunction with the dns
                  command if the DHCP server is set to configure DNS servers
                  for the clients, because the manually specified DNS servers
                  will be overwritten.
    
                  The DHCP client will NOT release the DHCP lease when the
                  sandbox terminates.  If your DHCP server requires leases to
                  be explicitly released, consider running a DHCP client and
                  releasing the lease manually.
    
           **iprange address,address**
                  Assign an IP address in the provided range to the last
                  network interface defined by a net command.  A default
                  gateway is assigned by default.
    
                  Example:
    
                  net eth0
                  iprange 192.168.1.150,192.168.1.160
    
           **mac address**
                  Assign MAC addresses to the last network interface defined
                  by a net command.
    
           **mtu number**
                  Assign a MTU value to the last network interface defined by
                  a net command.
    
           **net bridge_interface**
                  Enable a new network namespace and connect it to this
                  bridge interface.  Unless specified with option --ip and
                  --defaultgw, an IP address and a default gateway will be
                  assigned automatically to the sandbox. The IP address is
                  verified using ARP before assignment. The address
                  configured as default gateway is the bridge device IP
                  address. Up to four --net bridge devices can be defined.
                  Mixing bridge and macvlan devices is allowed.
    
           **net ethernet_interface|wireless_interface**
                  Enable a new network namespace and connect it to this
                  ethernet interface using the standard Linux macvlan or
                  ipvlan driver. Unless specified with option --ip and
                  --defaultgw, an IP address and a default gateway will be
                  assigned automatically to the sandbox. The IP address is
                  verified using ARP before assignment. The address
                  configured as default gateway is the default gateway of the
                  host. Up to four --net devices can be defined. Mixing
                  bridge and macvlan devices is allowed.
    
           **net none**
                  Enable a new, unconnected network namespace. The only
                  interface available in the new namespace is a new loopback
                  interface (lo).  Use this option to deny network access to
                  programs that don't really need network access.
    
           **net tap_interface**
                  Enable a new network namespace and connect it to this
                  ethernet tap interface using the standard Linux macvlan
                  driver.  If the tap interface is not configured, the
                  sandbox will not try to configure the interface inside the
                  sandbox.  Please use ip, netmask and defaultgw to specify
                  the configuration.
    
           **netfilter**
                  If a new network namespace is created, enabled default
                  network filter.
    
           **netfilter filename**
                  If a new network namespace is created, enabled the network
                  filter in filename.
    
           **netlock**
                  Generate a custom network filter and enable it.
    
           **netmask address**
                  Use this option when you want to assign an IP address in a
                  new namespace and the parent interface specified by --net
                  is not configured. An IP address and a default gateway
                  address also have to be added.
    
           **netns namespace**
                  Run the program in a named, persistent network namespace.
                  These can be created and configured using "ip netns".
    
           **veth-name name**
                  Use this name for the interface connected to the bridge for
                  --net=bridge_interface commands, instead of the default
                  one.
    


## Other



           **deterministic-exit-code**
                  Always exit firejail with the first child's exit status.
                  The default behavior is to use the exit status of the final
                  child to exit, which can be nondeterministic.
    
           **deterministic-shutdown**
                  Always shut down the sandbox after the first child has
                  terminated. The default behavior is to keep the sandbox
                  alive as long as it contains running processes.
    
           **join-or-start sandboxname**
                  Join the sandbox identified by name or start a new one.
                  Same as "firejail --join=sandboxname" command if sandbox
                  with specified name exists, otherwise same as "name
                  sandboxname".
