Here's something that has been giving me fits, and I'm hoping someone can
shed the light.
Both foo and bar are Solaris 7 machines.
I initiate ssh2 with port forwarding:
foo% ssh -L 1234:bar:21 foo
Which I take to mean this: "create an ssh session between foo and foo, but
forward foo's port 1234 to bar's ftp port." I shoul;d be able to ftp to
foo's local 1234 and actually be connected to bar's ftp, right?
Thus:
foo% ftp localhost 1234
Connected to localhost.
220 bar FTP server (SunOS 5.7) ready.
Name (localhost:phurvitz):
331 Password required for phurvitz.
Password:
230 User phurvitz logged in.
ftp> ls
200 PORT command successful.
425 Can't build data connection: Connection refused.
So I try this:
foo% ssh -L 1234:foo:21 bar
and then (in a shell still on foo)
foo% ftp localhost 1234
Connected to localhost.
220 foo FTP server (SunOS 5.7) ready.
Name (localhost:phurvitz):
331 Password required for phurvitz.
Password:
230 User phurvitz logged in.
ftp> ls
200 PORT command successful.
150 ASCII data connection for /bin/ls (127.0.0.1,35390) (0 bytes).
... all my files are listed ...
But why would I want to ftp to foo from foo?!! I want to ftp to foo's local
port 1234, and have that tunneled through ssh to bar's ftp port, but this
"425" error keeps me from building a data connection!
-P.
