NAME

   radiusd - RADIUS authentication/accounting server

SYNOPSIS

   radiusd [-a DIR] [-b] [-d DIR] [-h] [-f FILE] [-i IP_ADDRESS] [-l FILE]
          [-o] [-p NUM] [-q NUM] [-s] [-t NUM] [-v] [-w NUM] [-x]

DESCRIPTION

   radiusd is the RADIUS authentication and accounting server.

OPTIONS

   -a DIR Set the directory  for  RADIUS  accounting  logs  to  DIR.   The
          default location is /var/log/radiusd-livingston.

   -b     Use  users  DB  database  file  /etc/radiusd-livingston/users.db
          rather than the flat  text  file  /etc/radiusd-livingston/users.
          builddbm(8) may be used to create this database file.

   -d DIR Set  the  database  directory  to  DIR,  rather than the default
          /etc/radiusd-livingston.

   -f FILE
          Use FILE as a password file instead of using  getpwnam(3)  calls
          for "System" type authentication.

   -h     Show summary of options.

   -i IP_ADDR
          Bind the RADIUS server to IP_ADDR address, rather than accepting
          for all IP addresses on the local machine.

   -l FILE
          Log to FILE rather than the default behaviour of logging through
          syslog.

          If debugging is set, the default behaviour is to log to /dev/tty
          and setting -l syslog in this case only will log through syslog.

   -p NUM Sets the listening port of radiusd to NUM for  access  requests,
          NUM+1  for  accounting  requests,  NUM+5  and NUM+6 for handling
          proxy requests. The  default  is  to  use  the  entries  radius,
          radacct,  radius-proxy,  and  radacct-proxy  in /etc/services or
          1645, 1646, 1815 and 1816 respectively. (Debian's  /etc/services
          has  radius  as  1812 and radacct as 1813 in accordance with the
          RFCs, but has  no  entries  for  proxy  services.)  Most  RADIUS
          clients  default  to  1645  and  1646,  even  though  that is at
          variance with the RFCs.

   -o     Accept all-zero accounting request authenticators.

          The -o flag is provided for backwards  compatibility  with  non-
          compliant RADIUS clients. If radiusd is run with the -o flag, it
          logs unsigned accounting records, and flags them with  "Request-
          Authenticator  =  None".  If radiusd is run without the -o flag,
          it does not log unsigned accounting records.

   -q NUM Set the maximum number of outstanding  requests  (default  100),
          setting  a  limit  on the number of child processes radiusd will
          spawn off to handle authentication.

   -s     Single process mode. When  set  radiusd  does  not  fork  off  a
          separate  accounting  server,  and  does  not  fork off separate
          authentication responders for each authentication request.  This
          mode is needed if you wish to use the Virtual Ports feature.

   -t NUM Set  the  maximum  time  in  seconds  for a child authentication
          responder to live to NUM.  This  catches  responders  that  have
          become unresponsive. The default is 30 seconds.

   -v     Print version number of radiusd on standard error.

   -w NUM Sets  the  maximum  time in seconds for the proxy server to wait
          for a response before discarding the request to NUM. The default
          is 30 seconds.

   -x     Debug mode.

SIGNALS

   SIGUSR1
          Increment debugging level.

   SIGUSR2
          Disables debugging.

   SIGHUP is   ignored.  Changes  to  the  clients  and  proxy  files  are
          automatically noticed and acted upon. There is no need  to  tell
          radiusd to reread them.

FILES

   /etc/radiusd-livingston/dictionary
          RADIUS   dictionary.   /etc/radiusd-livingston/clients  List  of
          RADIUS clients and their shared secrets.

   /etc/radiusd-livingston/proxy
          Proxy configuration.

   /etc/radiusd-livingston/users
          RADIUS users database (plain ASCII format)

   /etc/radiusd-livingston/users.db

   /var/log/radiusd-livingston/CLIENT/details
          RADIUS accounting logs for CLIENT.
