hi i need script that will ssh to some Linux red hat via ssh and collect configuration file (rpm list and /etc/hosts etc..)

I read about the ssh and there is some problem to save the password in the script for this moment i don't care about that,

thanks

That's quite easy to achieve (with pubkeys so you don't have to enter passwords everytime). Run Remote Commands with SSH should get you started. However, there are much better tools for monitoring multiple boxes out there. Zabbix, Munin, Monit and Nagios are just the ones coming to mind right now.

thanks for the quick response,but i can't use those program only with bash script,
so. if you can supply some script that will collect information from Linux and then will move the information to other Linux via (scp, or rsync or sftp)

Simple sample script:

Code:

#!/bin/bash
OUT=report.out.txt
>$OUT
echo "Hostname : $(hostname)" >> $OUT
echo "Date : $(date)" >> $OUT
echo "Memory info: " >> $OUT
free -m >>$OUT
echo "Disk info: " >> $OUT
df -h >>$OUT
scp $OUT you@somewhere.com
# mail -s "Sys Info" you@somewherelese.com < $OUT

Now write and modify script as above.

To copy files to folder

Code:

cp /path/to/file /path/to/folder

NO need to use `cmd` or $(cmd) statement as script can execute cp directly

Don't use telnet, it is insecure protocol. Use openssh server and open ssh client.

First set ssh keys, see my howto:
SSH Public key based authentication - Howto

Once done that, run ssh command as follows

Code:

ssh you@server-name.com command1
ssh you@server-name.com cp /path/to/something /here/dest
