RE: [PLUG] sunrpc..a few questions
|
Okay...so do I need it? How can I block access to it from the internet?
Can I use inetd.conf or hosts allow/deny to block those ports from the
internet?
In the past, these things were not detected by Saint. But Saint-2.2 with
NMAP indicates that the services are running. But, it doesn't flag them as
a vulnerability. Yet, everything I've read indicates that the "r" commands
are bad news. Aren't the "r" commands part of sunrpc?

'sunrpc' is just a port designation, it corresponds to port 111 tcp/udp.
It's handled by portmapper, which maps RPC [remote procedure call] program
numbers to higher numbered ports. RPC is a facility for invoking
functions [code] on remote machines -- of which, I think the NFS system
uses RPC to perform some of it's communications, so it requires portmapper
to be running to function correctly (NFSD needs it I think, but possibly
not the client).
