Thanks Daniel for the explanations about posting a message properly.
This is what it shows after rpcinfo:
program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper
391002 1 tcp 32768 sgi_fam
391002 2 tcp 32768 sgi_fam
For a minute before doing this, I thought that somehow port 111 was
exposed to the internet. Mostly because the firewall did not show this
port open previously. However, since it appears to be solely the portmap
server, it seems to be ok. I wonder why the firewall shows this port open
and before it did not. Anyways, it seems to be open only locally.
