Problem:
I have some HP-UX 11.31 servers and generally, I connect with these servers through SSH. I noticed that response of one sever becomes very slow during login. When I connect to this server through SSH (with any user normal or root) it takes too much time after entering the password. Sometimes it takes about 2 minutes to get a command prompt.
Reason:
The reason for the above problem was the big size of the below-mentioned files.
/var/adm/wtmp
and
/var/adm/btmp
Solution:
Solution is very simple just empty the above mentioned files using the below command.
# cat /dev/null > /var/adm/wtmp
# cat /dev/null > /var/adm/btmp
The above problem also may be due to the bad configuration of the /etc/nsswitch.conf file.
