I've switched over to Net::SSH::Perl to see if that is any better. I turned on its debugging machinery

It appears that the server won't accept a "password"! I don't exactly know why it says "empty authentication" and doesn't seem to try sending my password. The code is simple 
my $ssh = Net::SSH::Perl->new("shell02.theworld.com", 
                               protocol => 2,
                               debug=>1,
                               strict_host_key_checking => "no",
                               options => ["PasswordAuthentication yes
+"]
                             ) ;
$ssh->login($login{user}, $login{password}) ;

I'll have to read up on what happens with the SSH "user-authentication service" and try to understand what's happening there. I can see why everyone who has been successful with SSH has reverted to using publickey auth..:o)
