Connect to multiple unix servers

[darkknight56]

Hello. I'm new at perl and am faced with a problem. I work with
multiple unix servers and I need to execute the same commands on each
of them. I'd like to automate this with perl so I was hoping someone
could point me in the right direction as to what package to use or
where there may be some code snippets I could learn from and modify.
I know there is the telnet module but if I fail to connect on one
server, I still need to proceed onto the next one.

Any help would be appreciated.

Debian distributed shell is your friend.

Sorry but I'm running a recent Activestate release of perl from a
Windows server to the various unix servers. From windows, I need to
connect to one unix server, execute some commands, logout from that
box then move onto the next box and repeat the process all over again.

Net::Telnet?

Net::Telnet?

Telnet is deprecated.

Net::SSH will do nicely. It requires an ssh.exe on the Winbox, but
Putty and Cygwin/OpenSSH are just another free download away.

Perl won't solve your problem: executing commands on a distributed
network. Check out tools like cfengine and Puppet that specialize in
doing this (especially if the commands are not going to change much over
time). cfengine in particular will do many of the tasks you're probably
thinking of, like monitoring/restarting/killing processes and
distributing files, without any custom work.

You can do that with Net::Telnet and Net::SSH.

Net::Telnet can be useful running over an ssh connection to change
passwords however.

Well yeah. There is equipment out there that doesn't speak SSH yet, so
Telnet-over-SSH is a decent solution for that.

OTOH, for the parent use case, Telnet is definitely deprecated.

Either use putty in a simple for loop, or check wether dsh is available under cygwin.
