gnus: Common Variables

 
 6.2.1.3 Common Variables
 ........................
 
 The following variables affect the behavior of all, or several of the
 pre-made connection functions.  When not specified, all functions are
 affected (the values of the following variables will be used as the
 default if each virtual ‘nntp’ server doesn’t specify those server
 variables individually).
 
 ‘nntp-pre-command’
      A command wrapper to use when connecting through a non native
      connection function (all except ‘nntp-open-network-stream’,
      ‘nntp-open-tls-stream’, and ‘nntp-open-ssl-stream’).  This is where
      you would put a ‘SOCKS’ wrapper for instance.
 
 ‘nntp-address’
      The address of the NNTP server.
 
 ‘nntp-port-number’
      Port number to connect to the NNTP server.  The default is ‘nntp’.
      If you use NNTP over TLS/SSL, you may want to use integer ports
      rather than named ports (i.e., use ‘563’ instead of ‘snews’ or
      ‘nntps’), because external TLS/SSL tools may not work with named
      ports.
 
 ‘nntp-end-of-line’
      String to use as end-of-line marker when talking to the NNTP
      server.  This is ‘\r\n’ by default, but should be ‘\n’ when using a
      non native telnet connection function.
 
 ‘nntp-netcat-command’
      Command to use when connecting to the NNTP server through ‘netcat’.
      This is _not_ for an intermediate host.  This is just for the real
      NNTP server.  The default is ‘nc’.
 
 ‘nntp-netcat-switches’
      A list of switches to pass to ‘nntp-netcat-command’.  The default
      is ‘()’.
