how to open port 111?

[haek@hem.passagen.se]

Hello again debian-user!

I have a problem with the portmapper not responding to remote calls:
(jobbet=agda=130.241.119.140, amin=194.236.111.14)
"hans@amin:~$ rpcinfo -p jobbet
rpcinfo: can't contact portmapper: RPC: Remote system error - No route to host"

It works alright from localhost though:

"[22:33:52]hans@agda:~>rpcinfo -p
   program vers proto   port
    100000    2   tcp    111  portmapper
    100000    2   udp    111  portmapper
    100024    1   udp    649  status
    100024    1   tcp    651  status
    100003    2   udp   2049  nfs
    100003    2   tcp   2049  nfs
    100005    1   udp    660  mountd
    100005    2   udp    660  mountd
    100005    1   tcp    663  mountd
    100005    2   tcp    663  mountd
[22:33:53]hans@agda:~>"

Now, I ran nmap from amin and discovered that port 111 is not "open"
but "filtered". 

"hans@amin:~$ nmap jobbet

Starting nmap V. 2.12 by Fyodor (fyodor@dhp.com, www.insecure.org/nmap/)
Interesting ports on jobbet (130.241.119.140):
Port    State       Protocol  Service
22      open        tcp        ssh
25      open        tcp        smtp
80      open        tcp        http
111     filtered    tcp        sunrpc
651     open        tcp        unknown
663     open        tcp        unknown
2049    open        tcp        nfs"

How do I open up port 111 on agda? Who is "filtering" this port? Is it the tcpd? I have copied /etc/hosts.allow /etc/hosts.deny and /etc/inetd.conf from amin to jobbet(=agda), since amin had port 111 "open" alright when connecting from jobbet, and restarted inetd and portmap but without success.
