NAME

       radwho - show online users

SYNOPSIS

       radwho  [-c] [-d raddb_directory] [-F radutmp_file] [-i] [-n] [-N nas_ip_address] [-p] [-P
       nas_port] [-r] [-R] [-s] [-S] [-u user] [-U user] [-Z]

DESCRIPTION

       The FreeRADIUS server can be configured to maintain an active session database in  a  file
       called radutmp. This utility shows the content of that session database.

OPTIONS

       -c     Shows caller ID (if available) instead of the full name.

       -d raddb_directory
              The   directory   that   contains  the  RADIUS  configuration  files.  Defaults  to
              /etc/freeradius/3.0.

       -F radutmp_file
              The file that contains  the  radutmp  file.   If  this  is  specified,  -d  is  not
              necessary.

       -i     Shows the session ID instead of the full name.

       -n     Normally  radwho  looks up the username in the systems password file, and shows the
              full username as well. The -n flags prevents this.

       -N nas_ip_address
              Show only those entries which match the given NAS IP address.

       -p     Adds an extra column for the port type - I for ISDN, A for Analog.

       -P nas_port
              Show only those entries which match the given NAS port.

       -r     Outputs all data in raw format - no  headers,  no  formatting,  fields  are  comma-
              separated.

       -R     Output all data in RADIUS attribute format.  All fields are printed.

       -s     Show full name.

       -S     Hide shell users. Doesn't show the entries for users that do not have a SLIP or PPP
              session.

       -u user
              Show only those entries which match the given username (case insensitive).

       -U user
              Show only those entries which match the given username (case sensitive).

       -Z     When combined with -R, prints out the  contents  of  an  Accounting-Request  packet
              which  can  be  passed  to  radclient,  in  order  to "zap" that users session from
              radutmp.

       For example,

              $ radwho -ZRN 10.0.0.1 | radclient -f - radius.example.net acct testing123

       will result in all an Accounting-Request packet being sent to  the  RADIUS  server,  which
       tells the server that the NAS rebooted.  i.e. It "zaps" all of the users on that NAS.

       To "zap" one user, specify NAS, username, and NAS port:

              $ radwho -ZRN 10.0.0.1 -u user -P 10 | radclient -f - radius.example.net acct testing123

       Other combinations are also possible.
