su login problem
Hi all
We use putty to login into our redhat servers with 2.4.21-27.0.1.ELsmp kernel.
In a particular redhat server I am able to login as a normal user via telnet. sshd is running but I am not able to use ssh logins.
Even in telnet I am not able to use "su" or "su -" to switch to any other user. If I use su like
$su - user1
or
$su user1
the putty terminal just freezes. The putty client is fine as I do not have any problem in logging to other servers.
/bin/su has -rwsr-xr-x access rights, so suid is not a problem.
We have had similar problems before, but a reboot usualy solved it.
This time I want a permanent solution as rebooting often is not an option. As I am not able to login as root, I cannot view files like
/var/log/messages
/var/log/secure
Thanks
