You can allways use the last command

man last

Hi Amit:

> I could not see any login in Feb or March even though i logged into the box. Is there anything wrong

When you run 'last' it tells you the *beginning* date of the log activity at the end of its run. Look there.

The absence of a '/var/adm/wtmp' file turns off logging. It is very common to null the file (cat /dev/null > /var/adm/wtmp), since like all log files, it grows without bounds.

I belive the file is getting very big and throws the below error.

# last | grep "Mar"
Invalid record size. Unable to continue ...

Any suggestions?

Keep Smiling ;)

check if you could use the

#lastb

I think you need to trim the /var/adm/*tmps

should be the wtmps and btmps.

The file is corrupted. You might be able to write a program to see if you can read past the error.
