Radwho Command Line Options

The following command line options can be used to modify the behavior of the program:

-A

--all

Display the information about logged-out users as well. The logged-out users are shown with Proto field set to HUP.

-c

--calling-id

Display the calling station ID in the second column.

-d NAME

--directory NAME

Set the radius configuration directory name.

-D {short|abbr|full}

--date-formap {short|abbr|full}

Set the date representation. By default dates are output as DOW HH:MM, where DOW means the day of week abbreviation, HH and MM mean hours and minutes respectively. This corresponds to option -D short. Other available formats are:

`abbr '

Abbreviated date: MM/DD HH:MM, where MM is a two-digit month number, DD -- a two-digit day of month.

`full '

Full data output, like this:

    Mon Dec 18 12:29:38 EET 2000

-e STRING

--empty STRING

Display any empty field as STRING. This is useful when the output of radwho is fed to some analyzing program, as it helps to keep the same number of columns on each line of output.

-F

--finger

Start in fingerd mode. In this mode radwho emulates the behavior of fingerd(8) utility. Use this option if starting radwho from the /etc/inetd.conf line like this:

    finger stream tcp nowait nobody /usr/sbin/radwho radwho -fL

This mode is also enabled by default if radwho notices that its name (argv[0]) is `fingerd' or `in.fingerd'.

-H

--no-header

Don't display header line.

-i

--session-id

Display session ID instead of GECOS in the second column.

-I {smart|ip|nodomain}

--ip-format {smart|ip|nodomain}

Change IP address representation. The meaning of the argument is as follows:

`smart '

Select the best representation. The following rules apply:

1. For a NAS use its short name from `naslist'. If there is no short name, use its long name. If there is no long name either, go to 2.
2. Resolve IP address to FQDN.
3. If the IP cannot be resolved, use dotted-quad representation of the IP

`ip '

Display IP in dotted-quad form.

`nodomain '

If the IP can be resolved to a fully qualified domain name, use the hostname part of it, i.e. any characters up to the first dot.

-u

--local-also

Display information about local users from the system `utmp' file. May prove useful when running radwho as a finger daemon.

-n

--no-resolve

Do not resolve IP address. It is a synonym for -I ip.

-o FORMAT

--format FORMAT

Select customized output format. This can also be changed by setting the value of environment variable RADWHO_FORMAT. The format string is a comma-separated list of format specifications in one of the following forms:

field
