Hi! mountd (rpc.mountd): normally uses a random port allocated by portmapper. It is possible to configure a fixed port number by supplying the ³-p² command line option when the program is launched. This can be done by editing the file /etc/sysconfig/network and adding the following line: MOUNTD_PORT=4002 rpc.quotad should be at least version 3.08 In the file /etc/rpc and check that the following line is present: rquotad 100011 rquotaprog quota rquota It should be there, but if isnt, then add it yourself. Then edit the file /etc/services and add the following lines: rquotad 4003/tcp rquotad 4003/tcp Then iptables should be able to have something like these lines for NFS: iptables -A INPUT -s ip.pc.client -d 0/0 4000:4003 -p 6 -j ACCEPT iptables -A INPUT -s ip.pc.client -d 0/0 4000:4003 -p 17 -j ACCEPT :) Missy Koos Webmistress & Database Developer Student Affairs & Services Michigan State University 113 Student Services Building East Lansing, MI 48824 517.355.9510 x138 On 5/13/05 4:24 PM, "Wheeler, Bill" <[log in to unmask]> wrote: > Hi, all-- > I've been trying to set up an NFS server on a Linux box with iptables for > packet filtering.
