Hi,

I have limited access to several servers (key based auth) but cron facility is not available for me. Those servers getting filled up by large apache logs and I have to login to each node manually and clean them each and every day.

I tried to write a script to run from login box but when i try that it looks like it is looking for logs in the local server (login box).

So current situation is;

localbox --> ssh junadmin@server1 "sh /tmp/test/dozip.sh". when executed from login box it says "gzip: a.txt: No such file or directory"

dozip.sh is a one line script in server1's /tmp/test/ which says "gzip a.txt". a.txt is a test file created in server1's /tmp/test dir.

how can i modify this so that the script in server1 will look for files in that server and zip them?

Google showed another command called rsh but in my env it is also not avil.

First you should use full path to excutables in any of your scripts, second do acd to the directory where you whish to do work or specify full pathnames to files .

Hi there,

As I can understand the scenario you are having a server which generate lot of apache logs and you have to clean them up manually. I will give this server a name say server1.

What you are looking for is to zip these log files on server1 and copy it to server2 and then remove the log files from server1. If that is the case you can go with the following:

1. Use this link to know how to ssh without using password: http://www.linuxproblem.org/art_9.html
2. Create a script say: vi /home/username/remotescript.
3. chmod 777 /home/username/remotescript
4. Once above is configured you can simply add the following commands to the script:

tar -cvf /test/logs.tar /test/logs
scp -rv /test/logs.tar username@xxx.xxx.xxx.xxx:/logs_from_remote/

5. Put this script in crotab
6. If you want to remove the log files one copied to other server then you can create a script for removing logs from original server.

I hope this helps.

you can simply use: ssh junadmin@server1 "/usr/bin/gzip /tmp/test/a.txt"

When you say that cron is not available, you mean it’s blocked by the admin for users and crontab -e won’t work? What about running your own background process on these machines which checks every few minutes the size and takes action.

logrotate ?
