About SSH Connection

[kini]

How i can change the SSH port? Because when i stop or make only local connection to SSH - DNS after sometime don't work and all sites is down. If you try to open some site the message is: Connection Time Out..

I have very more failed logins if i have global connection to SSH..

I use daily SSH not issues.

Do you have DNS logs? Are you using NAT? Dedicated at a datacenter? No routing?

I was sure you were routing traffic. You need to check how your network settings.

Guys i don't know why you make hosting control panel when not knowing how to help your users?

I have education for internet networks and i have made two of largest hosting company's in Bulgaria and i sold this company's successful. Everything is good on my network. Beleave me!

Sorry but this is unacceptable. It is good that you desire for this work. Admiration for all this!

I am ready to donate for Sentora, but there are have irregularities. You will say that it is open source and no one is obliged to use but this is not true. Some users buy network and server equipment for this.

When find a solution for this and other problems i will edit the thread. Thank you!

You are on the wrong side here. Are you aware you are getting almost the best support we can give here for free?

1. Your network config is uncommon for use as most of the configs we use in production and test are servers directly connected to the internet.

2. My advice again related to my current experience check nat setup and FirewallD in centos 7 as it uses a different firewall zones logic unlike iptables.

3. Check if you have any IDS that may burn DNS port.

It's hard to support configs we don't test and we test a lot of configs/os already.

Your feedback & help is always welcome.
