ok, the current “hosts” file shows: #
# /etc/hosts: static lookup table for host names

#<ip-address> <hostname.domain.org> <hostname>
127.0.0.1 localhost.localdomain localhost
::1 localhost.localdomain localhost ip6-localhost

# End of file
Thank you for sharing the contents of your /etc/hosts file. The /etc/hosts file is used for static hostname resolution on your system. It maps IP addresses to hostnames, allowing your system to resolve and connect to local addresses without querying DNS servers.

In the provided example, the 127.0.0.1 IP address is mapped to the hostnames localhost.localdomain and localhost. Similarly, the ::1 IPv6 address is mapped to the same hostnames with the addition of ip6-localhost.

The “localhost” entry typically refers to the loopback address, which points to the local machine itself.

Please note that modifications to the /etc/hosts file should be performed with care, as it directly affects how your system resolves hostnames. It’s always a good idea to keep a backup and consult proper documentation or seek assistance from a knowledgeable individual if you have any concerns or further specific requirements related to hostname resolution on your system.
I don’t know, wireshark shows an error while trying to execute an analysis: Couldn’t run /usr/bin/dumpcap in child process: Permission denied
If you are encountering a “Permission denied” error when trying to execute Wireshark analysis and the error message specifically mentions “/usr/bin/dumpcap,” it indicates that the necessary permissions are not properly set for the dumpcap binary.

To resolve this issue and allow Wireshark to run the analysis successfully, you can try the following steps:

1. Ensure that you have administrative or root privileges on your system.

2. Set the correct ownership and permissions for the dumpcap binary by running the following commands:

sudo chown root:wireshark /usr/bin/dumpcap
sudo chmod 750 /usr/bin/dumpcap
sudo setcap cap_net_raw,cap_net_admin=eip /usr/bin/dumpcap

These commands change the ownership of /usr/bin/dumpcap to root with the group set to “wireshark.” The permissions are set to 750, allowing read, write, and execute permissions for the owner and read and execute permissions for the group. Additionally, the necessary capabilities are set for capturing network traffic.

3. Confirm that the changes are in effect by running the command:

ls -l /usr/bin/dumpcap

Ensure that the ownership, group, and permissions match the changes made in the previous step.

After applying these changes, try running your Wireshark analysis again. The “Permission denied” error should no longer occur, and you should be able to execute the analysis successfully.

If the issue persists or if you have any further questions, please let me know.
the current state is as follows.: “-rwxr-x— 1 root wireshark 129544 Jun 28 13:52 /usr/bin/dumpcap”
maybe I just need to launch wireshark with some root permissions within from non-root environment?
Based on the current state of the /usr/bin/dumpcap binary, the ownership and permissions appear to be correctly set, with root as the owner and wireshark as the group. The permissions are set to allow read, write, and execute permissions for the owner (root), read and execute permissions for the group (wireshark), and no permissions for other users.

Launching Wireshark with root permissions can potentially resolve the “Permission denied” issue you are experiencing. You can try running Wireshark with root privileges using the sudo command.

Please keep in mind that running Wireshark with root privileges can pose security risks, so it is advisable to exercise caution and only use root access when necessary. Additionally, make sure you trust the source of the network traffic you are capturing.

To run Wireshark with root privileges, use the following command:

sudo wireshark

Enter your password when prompted, and Wireshark should start with root privileges. This allows it to access and utilize the necessary permissions for capturing network traffic.

Alternatively, you can use the following command to launch Wireshark with root privileges for a specific capture:

sudo wireshark -k -Y ‘not tcp port 22’

This command captures all network traffic except for SSH (port 22) and displays it in Wireshark.

Please note that running Wireshark with root permissions should be done judiciously and responsibly. It is recommended to switch back to a non-root user once you have completed the necessary network analysis tasks.

If you continue to face issues or have any further questions, please let me know.
it analyzes. it captured some packet as: World of Warcraft
Command: Unknown (0xf9)
It seems that Wireshark successfully captured a packet related to the World of Warcraft game. In this case, the packet is labeled as “Command: Unknown (0xf9).”

The designation “Unknown (0xf9)” indicates that Wireshark has not been able to identify the specific command or protocol associated with this packet. The “0xf9” represents a hexadecimal value that corresponds to the unknown command.

When analyzing network packets, it is common to come across unidentified or unclassified packets, especially for proprietary protocols or protocols that are not widely recognized by Wireshark’s dissectors.

If you are interested in determining the exact meaning or purpose of this unknown command within the World of Warcraft context, you may need to refer to official documentation or resources specific to the game or network protocol being used. This can help shed light on the purpose and significance of the captured packet.

Wireshark provides extensive protocol dissectors, but there may be instances where certain protocols or specific commands remain unidentified. In such cases, further research or consulting game-specific resources may be necessary for a more accurate analysis and interpretation of the captured packets.
