access to another server

[coaxfiber]

How can i run a command to another server?

Example:

from

rc1: /m/home/coax

then i want to command "ls -ltr" to another server (different IP address) which is the

rc2:/m/home/coax/


Can I use the RCP?


Thanks.

Try ssh:

ssh coax@rc2 'ls -lrt /m/home/coax/'
 

assuming your user name is coax and the remote machine's name is rc2.

Sir,

How about without asking for a password?

Thanks Again.

Have a look at Public-Key Authentication for SSH (just google for 'ssh no password' and you will find a lot of tutorials how to set that up).

If the machines is trustworthy, you can also use rsh instead of ssh, google for 'rsh no password'.

I would recommend to have a look at the SSH solution, however.

Sir,
What should I do if the authorized_keys is not present in the folder .ssh2?

We're using 4 servers. But only in one server this 'authorized_keys' is existed.

Thanks.

You can simply create it.

Do you mean I can simply 'touch authorized_keys'.. and then that's it?

After I created the file I can just append the id_rsa.pub?


Thanks Very Much.

Yes, that should do it.

You may want to try that with one of your servers first before changing all of them :-)
