How do they connect to these workstations ? telnet/rlogin/ssh ? X11 ? Web ? other ?

Start with running the "who" command on each WS.

Hi !
Its NIS and they used ssh.

I use who command but it only displays list of that specific work station users. I want all users details connected to different work station.

If you insist wanting the information from a single machine, then enable rwho on each of the WS.

You'll get what you requested, unless I misunderstood it.
After in.rwhod is running on every machine, you can run the "rwho" command and see all logged-in users.

hi !
I run this command on my workstation. See the out put. Dont know wats the problem.
# /usr/sbin/in.rwhod
/var/spool/rwho: No such file or directory
# /usr/sbin/in.rwhod&
[1] 394
# /var/spool/rwho: No such file or directory
[1]+ Exit 1 /usr/sbin/in.rwhod
# rwho
/var/spool/rwho: No such file or directory

It looks very much the system wants you to create the /var/spool/rwho directory.

Code:

mkdir /var/spool/rwho

will do the trick ...

sajidmumtaz · 06-19-2006, 11:06 AM

thx jlliagre

. its working .
Now if i want that only root user can use rwho command not any normal user. So is it possible to do so ?
Regards.
Sajid.

jlliagre · 06-19-2006, 11:31 AM

Code:

chmod 0500 /usr/bin/rwho

mdhmi · 06-20-2006, 06:34 AM

Why enable the evil "r" commands unnecessarily?

w | wc -l displays the number of users connected.

You can run who, finger, etc via ssh.

ssh <hostname> "w | wc -l"

To have this daemon start automatically at startup, you can create a rc script.

e.g.

/etc/rc2.d/S99rwho

which contains this single line:

/usr/sbin/in.rwhod

Please let me know the solution for the following scenario...please...
How we can mount the compilers(directory) to all users using NFS automout and NIS? .

The users home directory is: /home/x1
the compilers directory should mount as : /home/x1/compilers as a demand through NFS auto mount.

Thanks
Mahaboob
