Servers in the same Windows and Centos domain do not see each other over the network. What needs to be configured?

Question

linux

There are two servers - Windows server 2008 and Centos 7. Both servers are in the same domain (Centos 7 pings the domain controller + Kerberos domain authorization works on Centos). But at the same time, the servers do not see a friend over the network in any way (pings do not even go, the destination host unreachable error). On the domain controller in AD, both of these servers are visible.

To be honest, not so long ago I began to get acquainted with Linux systems, and I can miss even all sorts of little things, so do not judge strictly plz. I'm trying to google, poke into all corners of Centos - so far unsuccessfully. So, a question for specialists - what kind of information do you need to conduct a primary data analysis, what and how?

Answer 1

1. What do pings have to do with ports?
2. If you look closely, the mask is different, so in fact the servers consider that they are on different subnets, or rather, 172.29.17.94 considers that they are on different subnets.
inet 172.19.0.1 netmask 255.255.0.0
inet 172.29.17.94 netmask 255.255.255.0

Answer 2

Pings and the domain are not connected in any way (*) unless of course they are in the same broadcast domain. Firewall is blocking. On Linux, iptables -F will disable the firewall. On Windows, you need to poke the mouse

Answer 3

Centos 7 pings domain controller...pings are not coming

The question is what ?, no ping?
IP addresses with subnet mask of both computers, ping from both sides.

Answer 4

The problem here is not in Linux, read about subnet masks, l2 routing and ip addresses
