Re^4: How to open nested SSH connection using perl

Hi, I am getting error at:

my $sshB = Net::OpenSSH->new($serverB,
                             user => $userB, password => $passwordB,
                             proxy_command => $proxy_command);

The error is:

ssh: illegal option -- W usage: ssh -1246AaCfgkMNnqsTtVvXxY -b bind_address -c cipher_spec [-D bind_address:port] -e escape_char -F configfile -i identity_file [-L bind_address:port:host:hostport] -l login_name -m mac_spec -O ctl_cmd -o option -p port [-R bind_address:port:host:hostport] -S ctl_path [-w local_tun:remote_tun] user@hostname command ssh_exchange_identification: Connection closed by remote host

That means your version of the SSH client is too old and doesn't support the `-W` feature. Your current solution is not very elegant because others may be able to use the tunnels you are creating to get to serverB without login into serverA first.	[reply] [d/l]
