ypbind grabs port designated for another service

["Thomas Gebhardt" <gebhardt@HRZ.Uni-Marburg.DE>]

Hi,

just had to handle a problem where CUPS (IPP printing subsystem)
didn't work any more after a reboot.

While checking the log files I noticed that cupsd could not bind
to its (static) port 631 because ypbind was listening on that
port already.

Is there a standard way to handle such a situation? How can I
prevent RPC services to use ports that should be reserved
for another daemon?

Thanks, Thomas
