ka-forwarder - Forward AFS Authentication Server requests to another
ka-forwarder [-p <port>] <server>[/<port>] [...]
ka-forwarder listens for requests for an AFS Authentication Server and
forwards them to a remove fakeka server. fakeka is a server that
answers AFS Authentication Server protocol requests using a regular
Kerberos KDC and is provided with some Kerberos 5 implementations.
fakeka has to run on the same host as the Kerberos KDC, however, and
AFS clients send all native AFS authentication requests to the AFS
database servers. If you don’t want to run your Kerberos KDCs and your
AFS database servers on the same host, run ka-forwarder on the AFS
database servers and point it to fakeka running on the Kerberos KDCs.
ka-forwarder takes one or more servers to which to forward the
requests. The default port on the remote server to which to forward
the command is 7004, but a different port can be specified by following
the server name with a slash ("/") and the port number. If multiple
servers are given, ka-forwarder will send queries to each server in
turn in a round-robin fashion.
Due to the way that ka-forwarder distinguishes from client requests and
server responses, any messages from one of the servers to which ka-
forwarder is forwarding will be considered a reply rather than a
command and will not be forwarded. This means that the servers running
fakeka will not be able to use native AFS authentication requests and
rely on ka-forwarder to send the requests to the right server.
ka-forwarder does not background itself. It should either be run in
the background via the shell, or run via the Basic OverSeer Server (see
By default, ka-forwarder listens to the standard AFS Authentication
Server port (7004). To listen to a different port, specify it with
the -p option.
Forward AFS Authentication Server reqests to the fakeka servers on
kdc1.example.com and kdc2.example.com:
% ka-forwarder kdc1.example.com kdc2.example.com &
Note the "&" to tell the shell to run this command in the background.
ka-forwarder only has to listen to port 7004 and therefore does not
require any special privileges unless a privileged port is specified
with the -p option.
