Server locks up when logging in

[Chassidy Rentz]

HP server locks up when anyone logs into the console or through a telnet session, but the problem does not occur when you log in with Secure Shell. Any advice on where to look for the problem? There are no errors displayed.

Hi,

Please, what does it mean "locks" ?
Could you also provide with the following:
OS version, is the system trusted, do you have NIS, which user[s] do you work with ?

Regards V.

You should also see if the syslog (/var/adm/syslog/syslog.log) has anything useful.

What is displayed on the screen when you login via telnet or on the console? Does it ever get to a prompt? Can you ping the server when this occurrs? Can you still SSH to the server when this occurrs?

take a username and go to his/her home directory. Move the .profile, .login, .kshrc, .cshrc and whatever else .*rc files to a temporary storage directory and see if you can login that way. More than likely, some esoteric command placed in the one of those startup profiles is blocking your access. If you have enabled disk quotas recently, it is a good candidate to do such nasty stuff.

There is an additional reason for the lock (or stuck). If a homedir there is on a NFS, which means that histfiles there are on NFS as well, the login process can take a lot of time. In order to resolve the problem, histfiles should be linked to a local directory, e.g. /tmp
