[ale] sun rpc services

[Joe Steele]

I generally don't believe that commenting out lines in 
/etc/services is a very effective way of blocking 
services.  The file is merely a convenience for connecting 
names with port numbers through the use of the 
getservbyname(3) function.  It might work in some cases, 
but daemons which don't bother looking up names and 
instead connect to ports directly using the port number 
will be unaffected by such efforts.

Do this:


[wss at uxwss wss]$ grep 111 /etc/services
sunrpc          111/tcp         portmapper      # RPC 4.0 portmapper TCP
sunrpc          111/udp         portmapper      # RPC 4.0 portmapper UDP 


[wss at uxwss wss]$ grep 111 /etc/services
#sunrpc          111/tcp         portmapper      # RPC 4.0 portmapper TCP
#sunrpc          111/udp         portmapper      # RPC 4.0 portmapper UDP 

Just a suggestion..
