Ok..... I run named on linux server (RH 6.2 kernel 2.2.18) with 2 NICs.
I configured named, via named.conf, to only listen on 1 port... but when i
scan my machine, both ports, i see domain service running on both the
servers IPs...
------------------------snipit of named.conf -------------------
options {
directory "/var/named";
auth-nxdomain no;
query-source port 53;
listen-on port 53 { 192.168.0.5; }; // only ip to bind named to
specified here..... the rest of the conf is zone defs
forward first;
-------------------------------- eos --------
no here is the netstat dump after i restarted the server and I only need
named to bind on nameserverNIC
---------------------snipit------------------------
tcp 0 0 serverNIC1:domain *:*
LISTEN
tcp 0 0 *:smtp *:*
LISTEN
tcp 0 0 *:telnet *:*
LISTEN
tcp 0 0 *:ftp *:*
LISTEN
udp 0 0 *:domain *:*
udp 0 0 serverNIC1:domain *:*
raw 0 0 *:icmp *:*
7
raw 0 0 *:tcp *:*
7
-------------------eos-------------------
Now if I scan both IPs , serverNIC1 and serverNIC2
open port 53 (domain) shows up on both IPs....... Is there some way to
disable this that i'm not seeing? I'm new at this so forgive me if the
answer is so very obvious but i'm not seeing it.
Thanks for any help
