Hi all, i told you i m getting mainly prob with frequently growing 2 files /var/adm/messages OR /var/adm/wtmpx.
I got a solution for overgrowing wtmpx. Below is the line need to put in cronjob. it will empty wtmpx file after every 30 minutes.
30 * * * * su - root -c "cat /dev/null > /var/adm/wtmpx" > /dev/null 2>&1
I get it from sun solaris 8. Although i am using solaris 9 but hope line should work it also . However, can anyone tell me what is the value here "root -c" and "2>&1"??

And about 'wtmpx'- the file is not understanble to me  . So, i plan to delete only lines from 'messages'
bash-2.05# tail -f wtmpx

Though it shows only 13 lines and lines are growing slowly but File size is growing to much fast. |
