Many advanced users are confused by Whonix's socksification of default applications such as ssh, wget, curl, etc. (For stream isolation https://www.whonix.org/wiki/Stream_Isolation) by uwt.
When they do ssh 192.168.0.11, ssh will go through a Tor SocksPort which won't be possible for local connections. It will result in the following error message:
libtorsocks(12021): connect: Connection is to a local address (192.168.0.11), may be a TCP DNS request to a local DNS server so have to reject to be safe. Please report a bug to http://code.google.com/p/torsocks/issues/entry if this is preventing a program from working properly with torsocks
Maybe in ~/.bashrc (as terminal greeting) we should output the contents of the UWT_DEV_PASSTHROUGH variable.
Users can either use export UWT_DEV_PASSTHROUGH=1 or ssh.whonix-orig to circumvent uwt. This is not well documented at the moment on the https://www.whonix.org/wiki/Stream_Isolation page.
