motd appears twice

JJX · 12-04-2005, 09:25 AM

When i login motd file apears twice
Anyway how to trace that?
What configuration mistake

can cause this behavior?

hussar · 12-04-2005, 09:46 AM

One possibility is that motd is run from /etc/profile and .profile in your home directory. Compare the content of both files and see if either of them calls motd. You should also look at .bashrc and .bash_profile if they exist.

.bash_profile exists only in /etc/skel

no reference to motd

OK, I was shooting from the hip and missed. I've looked at motd's man page now, and I see that /etc/motd is displayed by login "after a successful login but just before it executes the login shell."

What do you get when you do a `cat /etc/motd`? It is possible that the file carries the same message twice. (Hey, it could happen...)

What happens when you put a zero-length file called .hushlogin in your login directory? (In your home directory, do a `touch .hushlogin`.)

i dont see the motd (0 times)

hussar · 12-04-2005, 12:12 PM

Hey, it was worth a shot.

It seems to me there are two other possibilities. Login is reading /etc/motd twice, or login is being run twice.

Either way, I'm stumped. I will be interested to see what answer you find.

jrdioko · 12-04-2005, 01:52 PM

Hmm, what happens if you do a "grep -r motd /*" or something along those lines to see if there's a config or startup file somewhere that might be calling it. I assume if that existed it would be in one of the places you've already looked, but it's always worth a shot to double-check everywhere.

The problem must be to italics letters

How can i restart login service / pam.d or something to apply changes to these files?

jrdioko · 12-04-2005, 02:31 PM

I'd say comment out one of those sections and restart, but I don't know what pam is so I'll let someone else give a more informed comment.

JJX · 12-04-2005, 02:48 PM

pam is a sum of libraries that set the way a user will login/authenticate to the system.

any other way to restart the service without rebooting?
(i dont want to restart! uptime is bliss

)

jrdioko · 12-04-2005, 02:55 PM

You could look for the process (if it works that way) and kill and restart it, or try all the varieties of "foo/pam.d start/stop"

JJX · 12-04-2005, 05:13 PM

I marked as remark (nice expression :>)
in /etc/pam.d/ssh

# Print the message of the day upon successful login.
#session optional pam_motd.so # [1]

I restarted the service using
"/etc/init.d/inetd restart"

now everything works fine!
thx a lot

jrdioko · 12-04-2005, 05:24 PM

I was close

Glad you got it fixed.
