Help with a quick script.

Stinkah

Ok, it's been a while, and I'm getting extremely lazy... but

Here's the deal.

I need to write a script which remotely accesses one machine from another and launch a said process on the remote box.

For example, telnet/ssh to a unix server and start an X process.

Any help much appreciated.

P.S. It might be noted that I don't have a homedir on the remote machine, instead I simply have a login.

could do worse than use the Net::Telnet module for Perl...

use Net::Telnet;
$telnet = Net::Telnet->new
(
Timeout=>90,
Prompt =>'%',
Host => 'remotehost.com'
);

$telnet->login('username','password');
$telnet->cmd("cd directory");
$telnet->cmd("remotecommand");
$telnet->close;

and add that as a cron job if you want it done on a daily or whatever basis.

disclaimer: theres nearly always a much easier way then the ways I come up with.

I think using expect would be the bog standard way of doing this. man expect and read up on it :P But if you've got perl ...

Use remote execution.

Once you have set up server A on server B, server A can execute scripts on server B.

Once setup it might be a little easier to use than the perl option.

If you have ssh on both machines, then simply type
ssh user@machineB '/bin/sh /home/fred/scripts/run.sh'. This will just log in and execute the command and then exit the shell.

The use of keys with ssh would allow you to do this from cron without the need to input a password.
