yppush & iptables

[Norman Elton <wnelto@xxxxxxxxxx>]

I'm setting up a redundant NIS server on RHEL v3.1. When a user runs 
"make" to refresh the NIS maps, it's supposed to push the new maps to 
the slave server. It appears that the master server fires up a yppush 
process and binds it to a particular port using the portmapper.

Does anyone know a way to control what port it chooses, so that it can 
be properly firewalled? It appears to choose a port at random, making 
iptables impossible to use.

Any ideas? Thanks in advance,

Norman Elton
