Shell Programming and Scripting

rcp is remote copy. I think you could be getting this for 2 reasons.

A. Either you have 2 different login id's on these 2 machines.

B. The password for login id you are using on the server that you are executing the script has changed.

Let me know if you need more help.

THank you for your reply

I think none of two aletrnatives is the cause of this. Because yesterday it worked and the errror occured just today. No password changed.

Hmm ok one more thing to check out in that case

Verify if your .rhosts file in the remote server is configured properly i.e. to allow root access from your local host.

Check $HOME/.rhosts file

It should have permissioning as follows:

<machine name where remsh is getting executed> root

After checking above entries in .rhosts you can check the trust between the servers using..

#rlogin <servername> -l root

If you are able to logged in without prompting for password then you are done !!!

If the password is prompted then, remsh command also wont work.

Also if you have root access one thing might be that the passwords for root differ between the two machines.

Just spitting out different guesses here.

Hopefully this helps

Let me know

What about rsh ?? Can't i run a command/script in remote machine useing rsh ?

Examle-
rsh REOTE_MACHINE_NAME -n "chmod 664 SOME_FILE"

rsh or remsh is the same thing. Regardless of what you use if your remote host file (.rhost) files are not correct you won't be able connect between two different hosts.

I cannot undersand why remsh works properly and rcp (for turning back the value) doesnt work. I think the configuration for both this commands is the same, if it works for remsh should work for the other one too.
