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.
