I am installing a new Samba 4.2 Active Directory server on CentOS 7. I followed the Wiki instructions on how to create the server. I am using sernet-samba 4.2 binaries. Everything seems to be OK on the Linux side but I cannot get any windows client to successfully join the domain. Each attempt returns the following error message "RPC Server in not available". Below are the config file

Dear Simon, every second IP-address is unwanted. We restarted? eno4: nmcli con down eno4; nmcli con up eno4 and the second address vanishes. Then after a few ours, the second ip address reappears. This is the config-file of eno2: # cat ifcfg-eno2 TYPE=Ethernet PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=none DEFROUTE=yes IPV4_FAILURE_FATAL=yes IPV6INIT=no IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes

I've made 3 CentOS 7 installation attempts to configure a simple firewall/router box with 2 nics. I got myself into a circular scenario where NetworkManager and firewalld and /etc/sysconfig/network-scrpts/ifcfg-***** were interfering or overwriting each other. Needed to perform ifdown enp3s7 on the internal LAN nic in order to make the external internet enp2s0 reach websites and ping

Hello everyone I am running into some strange issues when configuring networking interfaces on my physical server running Centos 7.5. Let me give you an overview of what's going on: We have a physical server, running CentOS 7.5. This server has one 4 port NIC and one 2 port NIC and a Dell IDRAC port. The first port of the 4 port NIC, em1, is used for Management traffic. The first port of

I have a second server and gave it a WAN address and I can connect between them using their WAN addresses. That's what told me that my ip6tables weren't screwed up and that the problem lay elsewhere.

Hi, Tonight I upgraded two CentOS 8 boxes to CentOS 8.1 (1911). Then after a reboot of the first server the network was unavailable. In IPMI console everything except the network was looking good. Network was unreachable. No errors in NetworkManager. I also restarted NetworkManager, but it did not help. Then I discovered that the default gateway suddenly was missing. Then I rebooted the

I do see RA's emitting from the LAN interface, from radvd. Is there
