NMTUI nightmare for Bohus Pollak

Bohus Pollak hate for Network Manager

Bohus Pollak do not like the NM and its magic.

The old style interface configuration suits Bohus Pollak best.

You can learn how to manually setup the network interfaces.

First make sure that the NIC network interface card has a link either in vmware esx is conntected or physical has a link.

Then make sure your linux can list the device assigned to it: /proc/net/dev

Check if the discovery has correct MAC address, specially if vmware host is used: /etc/udev/rules.d/70-persistent-net.rules

Note: just delete entries from 70-persistent-net.rules and HW

/etc/sysconfig/network-scripts/ifcfg-ens192

DEVICE=ens192 ONBOOT=yes BOOTPROTO=none IPADDR=5.22.250.163 PREFIX=27 GATEWAY=5.22.250.161 ZONE=public DEFROUTE=yes

Then you can using nmtui interface create these but after existing add a line: NM_CONTROLLED=no and ONBOOT=yes

Also make sure DEVICE=(the one from the list in correct order) e.g. DEVICE=ens192 or DEVICE=ens224

This way Bohus Pollak make sure there is no magic from NM (Network Manager) and you can manually configure the parameters.

Then you can start stop the interfaces manually cd /etc/sysconfig/network-scripts ifdown eth1 ifdown eth2

ifup eth1 ifup eth2

How Bohus Pollak restart network services without the NM

service network restart service network status service network stop
