> Ah, interesting. I tried your suggestion, and I get the message
I tried it too, just for good measure. (I noticed that at least with
ssh1, I had to remember "-t" in the middle stages to force tty
allocation so the final ssh terminal session works properly.)
a $ ssh -t -L 54321:b:54320 b ssh -t -L 54320:c:54319 c ssh -L 54319:d:80 d
What I get after establishing the connection:
a $ telnet localhost 54321
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection refused
b $ telnet localhost 54320
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
Connection closed by foreign host.
c $ telnet localhost 54319
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
HEAD / HTTP/1.0
HTTP/1.1 200 OK
...
In other words, the forwarding does not quite work.
