I have worked a solution. It's not very good in that it stores passwords in the clear in the program and it may have other issues but it does seem to work.
#!/usr/bin/perl -w
use strict;
use Net::SSH::Perl;
my @logins = (
[undef,undef],
["myname","mypass"],
["local","localpw"],
["root",undef],
["root","pass1"],
["root","pass2"],
...
["root","passn]
);
my $ssh;
<open file with server list>
while (my $server = <read from file>) {
chomp $server;
print $server;
if (SSHConnect($server)) {
<do some work>
}
}
sub SSHConnect {
my $server = shift;
my $return = 0;
$ssh = Net::SSH::Perl->new($server,protocol=>'2,1');
foreach (@logins) {
my ($u,$p) = @{$_};
eval {
$ssh->login();
};
if (!$@) {
$return = 1;
last;
};
return $return;
}
A better solution may be to put login credentials into the server list (and encrypt this) but at this time I don't know what will work for each server and things can change.
