We have a server program "lpm" running as a service at boot. Other client programs send RPCs to it (via UDP). In this environment, I cannot get the RPCs to work. Portmap seems to be running fine, access to it is open in /etc/hosts.allow. lpm has registered itself with the rpc server, third line in this listing:
> rpcinfo -p
program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper
1107714020 1 udp 740

Here is simplest-case failure, sending an rpc request to lpm:
> rpcinfo -u ProBook-kubuntu 1107714020
rpcinfo: RPC: Port mapper failure - RPC: Unable to receive
program 1107714020 is not available
>
Our own client programs give similar errors when trying to talk to lpm.
I post here because, on my other kubuntu 10.04 physical platform, these same programs communicate fine. Configuration of service, portmap, and everthing else I can find is identical to that on the VirtualBox kubuntu guest.
Any ideas? Please? I have a deadline looming!
Thank you!
