=item B<onlyserver>

Produces output only for connections in which the process designated by the
B<port> argument is acting as the server.

=item B<onlyclient>

Produces output only for connections in which the process designated by the
B<port> argument is acting as the client.

=item B<onlyport>

Produces output only for connections between the process designated by the
B<port> argument and the specified port on any another machine. Use the same
port identifiers as for the B<port> argument.

=item B<onlyhost>

Produces output only for connections between the process designated by the
B<port> argument and any process on the specified machine. To identify the
machine, use the same notation as for the B<servers> argument.

=item B<onlyauth>

Produces output only for connections that are using the specified
authentication level. Provide one of the following values:

=over

=item *

B<auth> for connections at authentication level B<rxkad_auth>

=item *

B<clear> for connections at authentication level B<rxkad_clear>

=item *

B<crypt> for connections at authentication level B<rxkad_crypt>

=item *

B<none> for unauthenticated connections (equivalents are B<null>, B<noauth>,
and B<unauth>)

=back

=item B<version>

Reports the AFS build level of the binary file for the process designated by
the B<port> argument (or of the kernel extensions file for port 7001, the Cache
Manager's callback interface). Any other options combined with this one are
ignored.

=item B<noconns>

Produces only the standard statistics that begin the output produced by every
option (other than B<version>), and peer structure information if the B<peers>
option was selected, without reporting on any connections.

=item B<peers>

Outputs information from the I<peer structure> maintained for each port on
another machine to which the process designated by the B<port> argument has a
connection. There is information about roundtrip time and numbers of packets
sent and received, for example.

=item B<long>

Outputs additional information from the I<peer structure> maintained for each
port on another machine to which the process designated by the B<port> argument
has a connection. Only use this with the B<peers> argument.

=back

=head1 OUTPUT

The return value is a reference to a hash containing the
requested information. The keys that the hash may contain, along
with a short description of their values, are listed below:

=over

=item *

C<address>: the IP address of the machine given by the B<servers> argument.

=item *

C<port>: the port used.

=item *

C<version>: a description of the AFS build level.

=item *

C<tstats>: a reference to a hash containing standard statistics.

=item *

C<rxstats>: a reference to a hash containing detailed rx statistics.

=item *

C<connections>: a reference to an array of hash references containing information about each connection.

=item *

C<dallyCounter>: the number of dallying connections skipped.

=item *

C<peers>: a reference to an array of hash references containing information about each peer.

=back

The simplest case would be if the version flag was set.
The hash table would have only three keys in it:
