Security issues and LDM

Hi folks,

I'm sure everyone is aware of the ever increasing number of worms and other 
security compromises that are happening on the 'net these days. The local 
security folks here want to put a blanket filter on our internet 
connection for inbound port 111. The idea is that by filtering port 111, they 
make it just a bit harder for the various miscreants to find vulnerable RPC 

I'm trying to understand what effects that will have on our LDM servers. I 
vaguely remember running ldm for a while without having the /etc/rpc file 
edited properly, but that was a long time ago. I'm thinking we'll be able to 
connect to other servers, but nobody will be able to connect to us.

Longer term, has anyone considered what will happen with LDM as firewalls, 
proxy servers and other security measures become more prevalent? RPC isn't the 
most firewall friendly protocol ever invented.
