NAME

       alevtd - webserver for videotext pages


SYNOPSIS

       alevtd [ options ]


DESCRIPTION

       alevtd  is  http  daemon which serves videotext pages as HTML.  Tune in
       some station with a utility like v4lctl or some TV  application.   Then
       start it and point your browser to http://localhost:5654/

       Pages   may   be   requested   either  in  HTML  format  (http://local-
       host:5654/<page>/ or http://localhost:5654/<page>/<subpage>.html) or in
       ASCII  text  format (http://localhost:5654/<page>/<subpage>.txt).  Sub-
       page "00" can be used for pages without subpages.


OPTIONS

       -h     print a short help text and the default values for all  options.

       -v dev set vbi device (default: /dev/vbi).

       -d     enable debug output.

       -s     Write  a  start/stop  notice  and  serious errors to the syslog.
              Specify this option twice to get a verbose log  (additional  log
              events like dropped connections).

       -t sec set network timeout to >sec< seconds.

       -c n   set  the number of allowed parallel connections to >n<.  This is
              a per-thread limit.

       -p port
              listen on port >port< for incoming connections.  Default 5654.

       -n hostname
              set the hostname which the server should use (required for redi-
              rects).

       -i ip  bind to IP-address >ip<.

       -l log log  all  requests  to  the  logfile  >log< (common log format).
              Using "-" as filename makes alevtd print the access log to  std-
              out,  which  is  only  useful  together  with the -F switch (see
              below).

       -L log same as above, but additional flush every line.  Useful  if  you
              want monitor the logfile with tail -f.

       -u user
              set  uid to >user< (after binding to the tcp port).  This option
              is allowed for root only.

       -g group
              set gid to >group< (after binding to the tcp port).  This option
              is allowed for root only.

       -F     don't  run as daemon.  alevtd will not fork into background, not
              detach from terminal and report errors to stderr.

       -r     poll tv frequency, clear vtx page cache if  a  frequency  change
              was detected.
