A couple of points, you can construct a "fake" shadow file, and
don't use '-r' a lot.

Point 1:
You can make a "psuedo" shadow file out of the 4.x YP password file 
using the command:

	awk -F: '{printf("%s:%s:6445::::::\n",$1,$2);}' passwd > shadow

Then you can merge password changes with:

	nisaddent -f shadow -m shadow

Point 2:

The command 'nisaddent -r -f passwd passwd' and the command 
'nisaddent -m -f passwd passwd' will have the exact same overall
effect on the pasword table, it will now match the contents of the
file, *however* the way they work is vastly different and can
whomp the replication protocol.

In the first case, the operation is :
	1) foreach entry Delete it;
	2) add new entry "x"

For a 2000 record password file with 5 changes that is 2000 "deltas"

In the second case the operation is:
	1) If it exists in the file but not the table "add it"
	2) If it is different in the table "modify it"
	3) If it isn't in the file, "delete it"

For a 2000 record password file with 5 changes that is 5 "deltas".

   Anything!  Anythinganythinganything!

   Think of it like this:  Solaris 2.x has /vmunix with only a "modload"
   command and then on bootup modload's every thing that it possibly
   needs.  Device drivers, kernel modules, chocolate sodas.  (Ok, not
   chocolate sodas)

   From the way I read the Sun TechNotes article, my analogy isn't
   too far off.

   Don't know. :-)

Yes.  In the OpenBoot PROM you can issue commands like:

	boot disk /kernel/unix.old

Of course, there are certain gotchas.  For example, let's say that
you've replaced /kernel/unix and /kernel/fs/ufs and then you find that
they don't work...  Well when you boot the old kernel it'll still pick
up the new ufs module, which may or may not have problems (yes, I've
seen this personally).  The recovery, however, is not complex (simply
boot a CD, mount your root and perform the necessary mods and reboot).

Happy hacking,

My Sun SE told me on Tuesday ( after smiling sheepishly ) that the console

check my catalog to be sure.  If you had purchased a service contract

I'm using an SLC with sunos 4.1.3, with a HP 4M printer.

I have a null-modem cable, but all I seem to get is jiberish (in PCL mode).
I assume it's a parity problem, but no matter what I try, nothing seems
to change.

Once, I got some "real" text to appear, but when I tried it again, the
same garbled text started again.

Is there anyone who has a known printcap that works with an HP 4M? I'd like
to determine if my serial port got screwed up or the printer.

Also, is there anything extra needed to change a printcap setting (like kill
lpd?) How can I be assured the change is taking effect?

Interesting. Sun claims they only have the GUI-based version in 2.1. Are
you sure you aren't thinking of vanilla SVR4?

I would also like to point out (as I have been pointing out to Sun for over
a year) that quite a lot of sites have only ASCII terminal consoles on their 
servers (why spend $3K on a bitmapped console that isn't needed?). It's rather
difficult to do high-level administration on a server in single-user mode if 
there is no ASCII interface to the necessary tools.

Of course, I've also been told that admintool really doesn't cover very much
yet so you might as well just do it all by hand anyway ... 

Clearly the administration tools provided have a long way to go, but Sun is
aware of that.

The SPARCclassic is really cheap but most of us in the real

Does anyone know this for sure?  That is, actually installed one?

Hello,
  we are managing a small to medium network of SUNs here at Mnster.
We have a lot of IPXes, ELCs, some SS 10  and some other machines (also SUNs).
A lot of them have local discs, so we do not want a power-server 
machine but a different concept. 
  Until now we have so-called packages on some of the machines, that
are being distributed each night (if necessary). We also have a
database that defines which files should be copied and which should
be linked. But: This is a lot of work, and that's not what we want.
  We would appreciate a solution like this: Packages on different
machines, and each time a user accesses a file it is copied to his
local disc (if available). Thats a simple caching method, but we
did not run into a program that provides this.
  Does anyone know a (good!) caching program or does anyone have
a better solution to manage a network like ours?
  It would be really nice to get an answer of some experienced people!

Thanks,
Ulli

   had their time adjusted more than a few minutes. Immediatly I started
   getting NFS errors from the clients and mail. Here's part of my syslog
   showing what happened to one machine:
   [error messages deleted...]

    Using 'showfh' I found that the NFS error was referring to
   /etc/security/audit/bohr/files/19921207054007.not_terminated.boltzman.
   The security partitions are mounted with secure NFS from bohr. 'error 5' is
   EIO, I/O error.
   [more stuff deleted for brevity...]

    So, can anyone detail the sequence of what happened here? Does secure nfs
   use a timestamp, that I invalidated when I changed the time? Why did the
   warning messages come from the users on the consoles, and not root?

While I won't attempt to detail the sequence of events, I will answer
questions about secure RPC/NFS.  Yes, it does rely on timestamping.
An encrypted timestamp and window get packaged into each RPC request.
A server receiving a timestamp that is earlier than previous ones will
barf.  Using rdate in a secure NFS environment is a Bad Idea(TM).
Investigate other things like ntp that synchronize clocks by skewing
will probably solve your problems.

For some information on how secure NFS works, I believe you'll find a
description in the Answerbook.  If you don't have that, you can find
basically the same thing in a white paper on the subject that you can
get by anon FTP from opcom.sun.ca.

Assuming you have mounted a CD in the drive, it sounds like you have mounted it
read/write - which is a no-no with CDs.

Instead of mounting it like:
	mount /dev/sr0 /cdrom

Use:
	mount -r /dev/sr0 /cdrom

Subject: how connect different ip nets on one ether net
Date: 16 Dec 92 12:12:37 GMT
Organization: SEKAS, Munich, Germany


At our company, all UNIX boxes and all VMS boxes are connected with
each other over the same ethernet. The UNIX boxes communicate via
TCP/IP, the VMS boxes via DECNET. Also, one of the VMS machines is
running VMS-ULTRIX connection, so that we have a TCP/IP link between
both worlds. All this works fine.

Now, a customer has provided us with a demo version of some software
which we will be extending in the future. The problem is, that we can
not provide a fitting IP host address (with the leading numbers
matching) for the machine. It seems that the IP address is hard coded
in the demo software.

When we hook this machine up to the ethernet, it is not possible to
telnet etc. between this machine and the rest of our lan. We get
"network unreachable".

Is there any way, we could establish a connection? (Besides changing
the IP addresses of all other hosts). I mentioned our VMS-ULTRIX
connection, because it shows, that it can't be a principal hardware
problem. The VAX manages to talk in two different PROTOCOLS with only
one ethernet interface, so why shouldn't a Sun be able to talk in two
different IP nets with one interface. But all I have read on this
topic leads me to believe, that we would need a UNIX host with two
ethernet interfaces to make the connection.

Btw, the mismatching machine is a PC running SCO/ODT and we also have
machines running HP-UX 8.0 and SunOS 4.1.1B. Any suggestions anyone?
