[PROBLEM]
PuTTY (v0.58). When trying to establish a remote tunnel to a local RAdmin port (4899), I've experienced a strange behavior:

The remote-image is still visible, but the connection stalls. No new connections can be made, although the SSH session seems is perfectly fine.


[SOLUTION]
Try to simply minimize the PuTTY application window.

[PROBLEM]
When trying to use SSH-tunneling when the main SSH connection is going through an HTTP proxy, the tunnel "seems" open (regarding to the logs), but connections to a tunneled port are immediately closed.

In the logs you can see that the data fell out at the right location with the right IP and port information, but the data never reached it's destination.

The problem looks exactly like this one here:

Although that bug should be fixed by now, there still seem to be leftovers.


[SOLUTION]
Apply the suggested workaround, and enter "localhost, 127.0.0.1" in the proxy's "Exclude hosts/IPs" list.
