rev.ponytelecom.eu sending out SIP requests from my IPPBX
Hi,
I'm an IP PBX admin new to this forum. I usually don't have to administer the Linux side of things, but because of the COVID-19 crisis, we have to improvise a bit.
Our PBX is Running on FreeBSD version 11.3 release -p3
I was checking traffic with wireshark when I realised I had an unwanted visitor. I tried blocking traffic from firewall but realised something had installed itself on my server and running connection attemps from the inside to the outside.
I went through multiple forums. Tried blocking different IP addresses in my firewall but nothing works.
I need to find and Kill this process ...
How do I locate the process that's running these requests ?
And, how do I kill it for good ?
here are a couple of samples :
