hi,
In trying configure my firewall i found this ports open!
[root@server ~]# nmap 192.168.1.11
Starting Nmap 4.11 (
http://www.insecure.org/nmap/ ) at 2007-01-16 11:35 IST
Interesting ports on 192.168.1.11:
Not shown: 1674 closed ports
PORT STATE SERVICE
22/tcp open ssh
80/tcp open http
111/tcp open rpcbind
443/tcp open https
806/tcp open unknown
8080/tcp open http-proxy
Nmap finished: 1 IP address (1 host up) scanned in 0.459 seconds
[root@server ~]#
I have the following queries
1)which service runs on port 806
2)is it ssh, if so ,port 22 is also opened?
3)i have written a firewall rule to only allow my private network to access my web proxy service,but the above command output shows it is opened, not filtered?
[root@server ~]# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
ACCEPT tcp -- 192.168.1.0/24 anywhere tcp dpt:webcache
4)is it necessary to secure portmap service running on 111?i will use it for nfs.If so, how i can put an entry for it in hosts.deny file?
thanks for any response
regards,
Nirmal Tom
