Lightbulb connecting servers using SSH - help needed

Hi all,

I have a script written successfully and tuned by our members, now I am trying to execute this script from a taxi server.

My aim is I want to connect to four servers via ssh where I want to ran a script or run some commands and write the output to a file in the Taxi server.

I tried to write some script using some sample script but failed to succeed. Please help me.

Regards,
Senthil kumar AK

Hi all,

I tired this with a script available in the froum and its work fine for me now. I have created a public key so that the server ssh without any password prompt.

But now there is only one issue which I think I need some help.

This is the script which I have written in the taxi server where form I am connecting

bash-2.05$ cat connect.sh
#!/usr/bin/sh

while read box
do
ssh -n $box -l mvelmu 'hostname ; ksh /axphome/mvelmu/count.ksh' >> machineaddress.txt
done < "output.txt"

but when I ran this above script its returning with the results in the output.txt, but in the console I am able to see some system generated messages, how to suppress that messages.

Hi Senthil,

You can comment those Messages in the ssh file by using

*****************

and use in you file as

ssh -n $box -l mvelmu 'hostname 2>&1 | grep -v '^*' ; ksh /axphome/mvelmu/count.ksh' >> machineaddress.txt

Thanks,

#!/usr/bin/sh
while read box
do
ssh -n $box -l mvelmu 'hostname; ksh /axphome/mvelmu/count.ksh' >> output.txt
