             Bug #: 13736
           Summary: prohibit   --use-server=HOSTNAME   without :PORT
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: server
        AssignedTo: systemtap@sourceware.org
        ReportedBy: fche@redhat.com
    Classification: Unclassified


Without a given port number, without avahi, and without a IETF-assigned
port number, the stap-client is just guessing.  It should instead give up.

I would like to argue to leave things as they are. Currently, the user can
specify:

--use-server - the client uses avahi to find a suitable server on the local
network.

--use-server=HOSTNAME - the client uses avahi to find a suitable server on the
named host only

--use-server=HOSTNAME:PORT - the client contacts the specified server. Avahi is
not required.

An IP address may be specified for HOSTNAME. 

The above applies to --use-server in conjunction with --list-servers and to
--use-server when compiling a script (or both simultaneously).

--use-server=HOSTNAME is also useful in conjunction with --trust-servers for
adding|removing trust in servers on a particular host.

When avahi is not present both --use-server and use-server=HOSTNAME will fail
to find servers on the network, but could still find server certificates in NSS
databases related to that host (useful when removing trust).

I see no reason to disable this useful functionality.

Note that I was only talking about the non-avahi case.

Definitely or only usually?  If the former, OK, let's leave it alone.
