Does it interfere with the web server?

Question

linux

Hello. Please help me solve the problem. On the server, the webmin control panel lived quietly (on port 10000), Apache was also spinning. After installing some software, all this is no longer available. I don't understand what could be causing this.

Answer 1

Wangyu: iptables
ps It seemed to me that the web is given only over IPv6?

Answer 2

and where did you get the idea that someone is interfering? judging by these commands - everything works, everything obeys ...

Answer 3

well, everything is just telnet through each port and see who greets you
