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.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
