rpcbind / portmap not actually reachable on the network?

I'm trying to set up NIS and NFS on a Fedora 8 server. The first step (or so I read) is to be running portmapper, which I gather is called rpcbind as of Fedora 8.

On my server machine, I used the standard /etc/init.d/rpcbind script to start the service. it runs without crashing, shows up in ps output and I can use rpcinfo to see it is running:

Code:

[root@sa01 ~]# rpcinfo -p
   program vers proto   port  service
    100000    4   tcp    111  portmapper
    100000    3   tcp    111  portmapper
    100000    2   tcp    111  portmapper
    100000    4   udp    111  portmapper
    100000    3   udp    111  portmapper
    100000    2   udp    111  portmapper
    100000    4     0    111  portmapper
    100000    3     0    111  portmapper
    100000    2     0    111  portmapper

If I try using rpcinfo from another machine on the subnet (also Fedora 8) I get an error:

Code:

[root@vm02 ~]# rpcinfo -p 111.222.33.44
rpcinfo: can't contact portmapper: RPC: Remote system error - Address family not supported by protocol

Likewise, if I try running rpcinfo on the server using the loopback instead of the socket, I get an (different) error:

Code:

[root@sa01 ~]# rpcinfo -p 127.0.0.1
rpcinfo: can't contact portmapper: RPC: Unknown host

Documentation seems entirely lacking for rpcbind... can anybody lend me some insight?

Thanks much!

According to the man page, you have to set up hosts.allow file before you can connect to the portmap service form a remote. Have you done so?

I'm also wondering why you have versions 2, 3 and 4 running? Are they all necessary?

Versions 2, 3, & 4 run by default... I can't find any reference for configuration of rpcbind =(

For testing, since all of these hosts are behind a physical firewall, I have set up "ALL" in the hosts.allow file as well as disabled iptables.

Thanks!
