in my solaris 9 the file- /var/adm/messeages growin too first. by 24 hours 40MB. And always giving the below messages--
bash-2.05# tail -f messages
Nov 9 16:35:38 ME1 last message repeated 1 time
Nov 9 16:35:38 ME1 ftpd[16392]: [ID 476795 daemon.error] wtmpx /var/adm/wtmpx No such file or directory
Nov 9 16:35:38 ME1 last message repeated 1 time
Nov 9 16:35:38 ME1 ftpd[16393]: [ID 476795 daemon.error] wtmpx /var/adm/wtmpx No such file or directory

i then tried with #touch wtmpx. Although the above messages stops but wtmpx grows more faster than file 'messages'. so i again delete 'wtmpx'. For your information this SUN server uses for various types of FTP everyminutes. So, far i know 'wtmpx' files logs the user access. that is why it grows too fast.
I now plan to adjust a script in crontab which will delete first 100 lines from messages after 2/3 days.
But i don't know how to implement the script. Could anyone help me??
The following command will delete the first 100 lines from your wtmpx file:
$ sed '1,100d' wtmpx
However, if your wtmpx file grows by 40MB's every 24 hours I reckon 100 lines will not make much of a difference. Do a cat wtmpx |wc -l to count the lines and then decide how many lines you should delete to shrink the file size sufficiently.
Hi soliberus,
I tried to delete first 100 lines of file messages with command # sed '1,100d' messages. But it is not working. Please see below.
bash-2.05# cat messages |wc -l
36948
bash-2.05# sed '1,100d' messages
bash-2.05# cat messages |wc -l
36949
bash-2.05#
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.
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.
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"??
