Hi, all-- I've been trying to set up an NFS server on a Linux box with iptables for packet filtering. I need to open the ports used by rpc.mountd and rpc.quota, but the portmapper assigns them different port numbers every time they start. I can't specify the service in the iptables rule, because iptables (apparently) doesn't recognize services that aren't in /etc/services, and mountd and quota aren't listed there. I tried altering the commands in /etc/init.d/nfs to start mountd and quotad with specified ports, but that was blithely ignored. Any advice would be welcome. Thanks! --Bill.
