Ð?Ñ?едноÑ?о май не беÑ?е много Ñ?даÑ?ен оÑ?говоÑ?, Ñ?Ñ?жалÑ?вам.

man ssh

X11 and TCP forwarding
     If the ForwardX11 variable is set to â??yesâ?? (or, see the description of
     the -X and -x options described later) and the user is using X11 (the
     DISPLAY environment variable is set), the connection to the X11 display
     is automatically forwarded to the remote side in such a way that any X11
     programs started from the shell (or command) will go through the
     encrypted channel, and the connection to the real X server will be made
     from the local machine.  The user should not manually set DISPLAY.  For-
     warding of X11 connections can be configured on the command line or in
     configuration files.
 
     The DISPLAY value set by ssh will point to the server machine, but with a
     display number greater than zero.  This is normal, and happens because
     ssh creates a â??proxyâ?? X server on the server machine for forwarding the
     connections over the encrypted channel.
 
     ssh will also automatically set up Xauthority data on the server machine.
     For this purpose, it will generate a random authorization cookie, store
     it in Xauthority on the server, and verify that any forwarded connections
     carry this cookie and replace it by the real cookie when the connection
     is opened.  The real authentication cookie is never sent to the server
     machine (and no cookies are sent in the plain).

     If the ForwardAgent variable is set to â??yesâ?? (or, see the description of
     the -A and -a options described later) and the user is using an authenti-
     cation agent, the connection to the agent is automatically forwarded to
     the remote side.
 
     Forwarding of arbitrary TCP/IP connections over the secure channel can be
     specified either on the command line or in a configuration file.  One
     possible application of TCP/IP forwarding is a secure connection to an
     electronic purse; another is going through firewalls.

Ð?Ñ?егледай sshd.conf на маÑ?инаÑ?а оÑ? коÑ?Ñ?о иÑ?каÑ? да пÑ?Ñ?каÑ? пÑ?иложениÑ? и Ñ?Ñ?оÑ?веÑ?ниÑ?е ssh.conf на клиенÑ?а за веÑ?ниÑ?е опÑ?ии, Ñ?еÑ?Ñ?еÑ? на демона ако пÑ?омениÑ? неÑ?о и би Ñ?Ñ?Ñ?бвало да Ñ?абоÑ?и.
