| # SSH Tunnel Test Script | ||
| # | ||
| # Tests an SSH tunnel using wolfSSH and netcat (nc). | ||
| # | ||
| # Architecture: | ||
| # | ||
| # [nc client] --plain--> :12345 [wolfssh client] | ||
| # | | ||
| # SSH | ||
| # | | ||
| # [wolfssh server] :ephem --plain--> :11111 [nc server] | ||
| # | ||
| # The nc client sends each line of a Lorem Ipsum paragraph through the tunnel | ||
| # to the nc server one at a time. The server echoes each line back. Both sides | ||
| # verify receipt of every line. | ||
| # | ||
| # Ports used: | ||
| # 11111 - nc server (plain text backend) | ||
| # 12345 - wolfssh client listener (plain text, nc connects here) | ||
| # 22222 - wolfSSH rendezvous (SSH, internal use only) | ||
| # | ||
| # Requirements: nc (netcat), expect | ||
