Hi all,
I'm writing a script which will log into a list of servers if they have
public/private keypairs set up. If a server doesn't, I want the script to move
on to the next server rather than wait at a password prompt.
I'm using OpenSSH version 5.1p1 Debian-5, OpenSSL 0.9.8g 19 Oct 2007 on both
client and server.
I'm using this command:
ssh r...@ip -o PasswordAuthentication=no KbdInteractiveAuthentication=no
This works for most servers, but not all (on some of them the script halts at a
password prompt). I suspect those servers may run an older version of SSH which
doesn't support the options I'm providing. Any ideas? Thanks for any help.
try
ssh r...@ip -o PreferredAuthentications=publickey $command
And if you can write Perl, check also the Net::OpenSSH and
Net::OpenSSH::Parallel modules.
