I suppose telnet session filed because on the system where script is running have version of OpenSSH 4.3, but Net::OpenSSH module need OpenSSH 5.4 and upwards for creating tunnels. In case that i didn't have possibility to upgrade OpenSSH version is any alternatives way to create an ssh tunnel to gateway after that use tunnel to establish a telnet connection to remote host?
