SSH takes too much time while login

[#1]

Symptoms

Initial SSH login to the HP-UX 11.31 is slower without any errors. 

Diagnosis

Check the /var/adm/wtmp and /var/adm/wtmps files. IF it is huge in size. Move the file and re-create the file.

Found that the  /var/adm/wtmps file is very huge. 

Solution

Take a copy of the existing wtmps file and run the below command to empty the file. 

# cat /dev/null > /var/adm/wtmps 

This command empties the file and  doesnt corrupt the wtmps file. 

Alternatively you also delete and recreate this file. 

Issue resolved after emptying the wtmps file.
