Subject: I Have Multiple Ips But Can Only Telnet to One Interface. Not the subinterface. How to Fix?
Hi guys,
I have multiple IPs bound to my Centos 6.6 box but I can only telnet to one
IP. Any ideas on what to do? I've searched the internet so far with every
keyword I can think of to no avail. I can see that postfix is only
listening on the first IP and to localhost. The IP I cannot smtp to is on
ETH0:1. I can access it via port 80 (web traffic) but the connection is
refused if i try to telnet. [image: :shock:]
The domain I can telenet to is mymodeltalk.com
The domain I cannot telenet to is inform.mymodeltalk.com

Hi,
At a rough guess it's because those domains are pointing to different IPs:
inform.mymodeltalk.com. 3600 IN A 52.0.33.25
mymodeltalk.com. 600 IN A 52.0.148.79
Also you probably should use SSH to connect to the server and not telnet, unless there's a *really* good reason to use telnet. Fix the DNS so they're both pointing to the same server and I reckon you'll be good.
Cheers,
Matthew Moore
