Re: How to Block RPC Services ( Port 111 ) to avoid buffer overflow
A running rpcbind was usually activated because any service depends on it!
See "rpcinfo -p localhost" for registered services".
If you use NFS (either client or server) or any other RPC sercvice, you can't disable portmapper (rpcbind).
My 2 cents,
Armin

SolutionIf you like to disable it, stop nfs.client and nfs.server
or
cat /etc/services| grep 111
portmap 111/tcp sunrpc # SUN Remote Procedure Call
portmap 111/udp sunrpc #
Comment the above two entries..
But we like to know why you like to block it.
## You could also block the port on the Firewall.

Re: How to Block RPC Services ( Port 111 ) to avoid buffer overflow
Thanks for all of your kind input.
We recently have a security audit, so need to do this action. But, we seems still need this RPC service, so have any method to explain it to say the " RPC " service is safe ?
Thanks a lot.
