blocking ports

["Patrick Vermeij" <patrick@vermeij.net>]

Hi

I've got two questions :

1)
I want to block certain services for the outside world (like lpd etc) but NOT for the inside network
I thought I could block it with ipchains -A input -p tcp -d xxx.xxx.xxx.xxx 515 -j DENY
But if I telnet from a outside host to that port I can still connect
Well I think thats because the INPUT policy is ACCEPT (I think change that to DENY is rather not a good idea)
Is there another solutions for this ?

-------------------------------------------

2)
#showmount -e localhost
mount clntudp_create: RPC: Program not registered

#less /etc/host.allow  : 
[CUT]
portmap: 127.0.0.1

#ps -aux |grep rpc
root       957  0.0  0.0  1128    0 ?        SW   May22   0:00 [rpc.rquotad]
root      1027  0.0  0.1  1776  180 ?        S    May22   0:00 /usr/sbin/rpc.nfsd
root      1030  0.0  0.0  1776   64 ?        S    May22   0:00 /usr/sbin/rpc.mountd
root     12793  0.0  0.0     0    0 ?        SW   Jun15   0:00 [rpciod]
root     13120  0.0  0.0  1304    0 ?        SW   Jul09   0:00 [rpc.ugidd]

what is wrong?

thanx in advance
