Command not found when SSHing into Ubuntu 12.04

  • 772

I have an issue when logging into my Ubuntu 12.04 machine via SSH. It lags for about 40 seconds after printing half of the MOTD. Then it says 

[...]: command not found

and completes the login.

My MOTD reads as follows when I log in: 

Welcome to Ubuntu 12.04.3 LTS (GNU/Linux 3.2.0-35-generic-pae i686)

 * Documentation:  https://help.ubuntu.com/

[...]: command not found

I looked into modifying /etc/motd. However, the system uses update-motd and I can't wrap my head around how that program works. I can't find in which file the offending missing command is in. I like the dynamis MOTD, but this lag is driving me nuts. Lil help?

My /etc/update-motd.d/ looks like this:

me@server:/etc/update-motd.d$ ls -al
total 44
drwxr-xr-x   2 root root  4096 Aug 29 02:16 .

-rwxr-xr-x   1 root root  1158 Apr 19  2012 99-footer

Thanks in advance, wonderful internet folk.

    The file /etc/motd is updated every 10 mins (by default) by the scripts in /etc/update-motd.d. See: UpdateMotd

    The scripts are executed in order from 00 to 99 and write the output to the /etc/motd file.

    Hence the file /etc/motd is still static and I don't think will be the cause of your problem. Especially as the "Last Login" message is controlled by sshd and executed after motd. You should examine your profile scripts. Try your .profile, .bashrc or .bash_profile files in your home directory and look for the command that could be causing your problem.

    Less likely but possible is the file /etc/profile which could be being executed before your individual user profile is. Check that too if your personal profile doesn't show anything.
