NAME

       raddebug - Display debugging output from a running server.

SYNOPSIS

       raddebug  [-c  condition]  [-d  config_directory]  [-i ipv4-address] [-I ipv6-address] [-f
       socket_file] [-t timeout] [-u user-name]

DESCRIPTION

       raddebug is a shell script wrapper around radmin that automates the process  of  obtaining
       debugging  output  from  a  running  server.   It  does  this  without  impacting  service
       availability, unlike using radiusd -X.  There are  a  number  of  prerequisites  that  are
       required for its proper operation:

          * radmin must be available in the PATH.
          * The user running raddebug must have permission to connect to
            the server control socket.
          * The control socket must be configured.  For instructions, see
            raddb/sites-available/control-socket
          * The control socket must be marked as "mode = rw".
          * The user running raddebug must have permission to read and
            write files in the "logdir" directory.  This is usually
            /var/log/radiusd.

       For  a  number  of reasons, the debugging output is placed in an intermediate file, rather
       than being sent directly to standard output.  In order to prevent this file  from  growing
       too  large,  the  raddebug  program  is  automatically  terminated after 10 seconds.  This
       timeout can be changed via the "-t" parameter.

       When the script exits, debug mode in the server is disabled, and the intermediate file  is
       deleted.

       Debug  output  from  a  live  server  can be redirected to only one location.  If a second
       instance of raddebug is started while the first one is still running, the later  one  will
       over-ride the first one, and the first will stop producing output.

OPTIONS

       -c condition
              Set a specific debug condition.  The format of the condition is as specified in the
              CONDITIONS section of the unlang manual page.

       -f socket_file
              The path to the control socket.  See the radmin manual page for more description of
              this option.

       -i ipv4-address
              Show  debug  output  for  the client having the given IPv4 address.  This option is
              equivalent to using:
                 -c '(Packet-Src-IP-Address == ipv4-address)'

       -d config directory
              The radius configuration directory, usually /etc/raddb.  See the radmin manual page
              for more description of this option.

       -I ipv6-address
              Show  debug  output  for  the client having the given IPv6 address.  This option is
              equivalent to using:
                 -c '(Packet-Src-IPv6-Address == ipv6-address)'

       -t timeout
              Stop printing debug output after "timeout" seconds.  The default timeout  is  sixty
              (60)  seconds.   Use  "-t 0" to print debugging output forever, or until the script
              exits.

       -u name
              Show debug output for users having the given name.  This option  is  equivalent  to
              using:
                 -c '(User-Name == name)'
