snnewgroup

snnewgroup.v0.3.8(8)					      System Manager's Manual					      snnewgroup.v0.3.8(8)

NAME

       snnewgroup - create a new sn newsgroup

SYNOPSIS

       snnewgroup newsgroup [server] [port]

DESCRIPTION

       snnewgroup creates newsgroup assigning it an upstream NNTP server of server:port.  If port is not specified, defaults to 119.  If server is
       also not specified, newsgroup is created as a local group which is fed only by articles POSTed to it.

       You will need to be root or own /var/spool/sn in order to add new groups.

ENVIRONMENT VARIABLES

       SNROOT If this is set and is not empty, the value is used in place of /var/spool/sn, the default news spool directory.

FILES CREATED

       /var/spool/sn/newsgroup
	      Directory where articles will be stored.

       /var/spool/sn/newsgroup/.created
	      Empty file for the newsgroup creation time.

       /var/spool/sn/newsgroup/.serial
	      Where snget gets its idea of the new starting serial number for newsgroup on server server:port.	The value is initialized to 0.

       /var/spool/sn/newsgroup/.outgoing
	      If server is specified, is a symlink to  /var/spool/sn/.outgoing/server:port, which is a directory, created if it does  not  already
	      exist.  If server is not specified, no file /var/spool/sn/newsgroup/.outgoing will be created.  See also snsend.
