I am trying to connect to a RDP Windows server. This configuration works fine in Windows. But not in Ubuntu.
For whatever reason, when using rdesktop (or the remmina UI), the server does not respond.
I haven't found any question here or elsewhere about the server not responding. There is always an error message from what I can see.
It just timeouts on me after a good while. I seem to be able to connect fine via telnet.
I have to use a proxy. This is what I get:
In the proxy forward terminal:
$ ssh -L 3389:target:3389 uuuu@tunnel
channel 3: open failed: connect failed: Connection timed out
(NOTE: the error message appears only after a few minutes.)
In another terminal:
$ rdesktop -u uuuuuu -d dddddd localhost:3389
Autoselected keyboard map pt
ERROR: Connection closed
(The hostname and usernames have been censored.)
Strangely, when using Remmina, the debug window is completely blank.
Is it wrong username? Wrong domain? Wrong options? I just think it is odd that it gives no error. Any help diagonosticating the problem is welcome of course.
NOTE 1: I have used domain name "dddddd" because in the Windows setup, the username is "dddddd/uuuuu". I figured the left part was the domain. In the Windows password, I do not need to give a password before connecting. It says "You will be asked for credentials when you connect.", and a login prompt indeed shows up after connecting.
NOTE 2: I am using a fresh Ubuntu install, so I don't think there's a firewall problem. In fact, I can connect to another Linux server via VNC just fine.
PS: When I do ssh target, the command also timeouts with the server not responding. This seems to not be specific to rdesktop.
