Dear susers
I am installing a new FW with SuSE 8.0. I don't how the
port TCP 113 keeps open...
I just want to open a few ports to the world:
FW_SERVICES_EXT_TCP="ssh smtp http https"
When I scan the TCP ports from the external iface I see
that port 113 is not rejected:
22/tcp open ssh
25/tcp open smtp
80/tcp open http
113/tcp closed auth
443/tcp open https
I have checked the iptables command used by the FW and
it seems ok:
montblanc:/home/pep # SuSEfirewall2 debug | grep 113
iptables -A input_ext -j REJECT -p tcp --dport 113
--syn --reject-with tcp-reset
iptables -A input_dmz -j REJECT -p tcp --dport 113
--syn --reject-with tcp-reset
iptables -A input_int -j REJECT -p tcp --dport 113
--syn --reject-with tcp-reset
It should be rejecting any connections to port 113...
So far is not a big risk because I do not run any
application in that port. How can I reject connections
to port 113? What is SuSE FW is allowing port 113???
Cheers!
