gnus: Indirect Functions

 
 6.2.1.2 Indirect Functions
 ..........................
 
 These functions are called indirect because they connect to an
 intermediate host before actually connecting to the NNTP server.  All of
 these functions and related variables are also said to belong to the
 “via” family of connection: they’re all prefixed with “via” to make
 things cleaner.  The behavior of these functions is also affected by
 commonly understood variables (Common Variables).
 
 ‘nntp-open-via-rlogin-and-netcat’
      Does an ‘rlogin’ on a remote system, and then uses ‘netcat’ to
      connect to the real NNTP server from there.  This is useful for
      instance if you need to connect to a firewall machine first.
 
      ‘nntp-open-via-rlogin-and-netcat’-specific variables:
 
      ‘nntp-via-rlogin-command’
           Command used to log in on the intermediate host.  The default
           is ‘rsh’, but ‘ssh’ is a popular alternative.
 
      ‘nntp-via-rlogin-command-switches’
           List of strings to be used as the switches to
           ‘nntp-via-rlogin-command’.  The default is ‘nil’.  If you use
           ‘ssh’ for ‘nntp-via-rlogin-command’, you may set this to
           ‘("-C")’ in order to compress all data connections.
 
 ‘nntp-open-via-rlogin-and-telnet’
      Does essentially the same, but uses ‘telnet’ instead of ‘netcat’ to
      connect to the real NNTP server from the intermediate host.
      ‘telnet’ is a bit less robust because of things like
      line-end-conversion, but sometimes ‘netcat’ is simply not
      available.
 
      ‘nntp-open-via-rlogin-and-telnet’-specific variables:
 
      ‘nntp-telnet-command’
           Command used to connect to the real NNTP server from the
           intermediate host.  The default is ‘telnet’.
 
      ‘nntp-telnet-switches’
           List of strings to be used as the switches to the
           ‘nntp-telnet-command’ command.  The default is ‘("-8")’.
 
      ‘nntp-via-rlogin-command’
           Command used to log in on the intermediate host.  The default
           is ‘rsh’, but ‘ssh’ is a popular alternative.
 
      ‘nntp-via-rlogin-command-switches’
           List of strings to be used as the switches to
           ‘nntp-via-rlogin-command’.  If you use ‘ssh’, you may need to
           set this to ‘("-t" "-e" "none")’ or ‘("-C" "-t" "-e" "none")’
           if the telnet command requires a pseudo-tty allocation on an
           intermediate host.  The default is ‘nil’.
 
      Note that you may want to change the value for ‘nntp-end-of-line’
      to ‘\n’ (Common Variables).
 
 ‘nntp-open-via-telnet-and-telnet’
      Does essentially the same, but uses ‘telnet’ instead of ‘rlogin’ to
      connect to the intermediate host.
 
      ‘nntp-open-via-telnet-and-telnet’-specific variables:
 
      ‘nntp-via-telnet-command’
           Command used to ‘telnet’ the intermediate host.  The default
           is ‘telnet’.
 
      ‘nntp-via-telnet-switches’
           List of strings to be used as the switches to the
           ‘nntp-via-telnet-command’ command.  The default is ‘("-8")’.
 
      ‘nntp-via-user-password’
           Password to use when logging in on the intermediate host.
 
      ‘nntp-via-envuser’
           If non-‘nil’, the intermediate ‘telnet’ session (client and
           server both) will support the ‘ENVIRON’ option and not prompt
           for login name.  This works for Solaris ‘telnet’, for
           instance.
 
      ‘nntp-via-shell-prompt’
           Regexp matching the shell prompt on the intermediate host.
           The default is ‘bash\\|\$ *\r?$\\|> *\r?’.
 
      Note that you may want to change the value for ‘nntp-end-of-line’
      to ‘\n’ (Common Variables).
 
    Here are some additional variables that are understood by all the
 above functions:
 
 ‘nntp-via-user-name’
      User name to use when connecting to the intermediate host.
 
 ‘nntp-via-address’
      Address of the intermediate host to connect to.
