On OVH VPS running AlmaLinux 8, IPv4 IP address gets dropped. I have to connect to the server using KVM feature available in OVH control panel.
I checked IP of the server with the command
ip a
It did hot show any IPv4 IP address. I checked the network configuration file
vi /etc/sysconfig/network-scripts/ifcfg-eth0
That had the following content
BOOTPROTO=dhcp DEFROUTE=yes DEVICE=eth0 DHCLIENT_SET_DEFAULT_ROUTE=yes HWADDR=fa:16:3e:6b:a6:1a IPV6ADDR=2607:5300:201:3100::952/56 IPV6INIT=yes IPV6_AUTOCONF=no IPV6_DEFAULTGW=2607:5300:201:3100::1 IPV6_FORCE_ACCEPT_RA=no MTU=1500 ONBOOT=yes TYPE=Ethernet USERCTL=no
To make the IP static, I made the following changes.
Find
BOOTPROTO=dhcp
Replace with
BOOTPROTO=static
Also added following 2 entry
IPADDR=144.217.13.76 GATEWAY=144.217.12.1
144.217.13.76 is the IP address of the VPS.
144.217.12.1 is the gateway used on the VPS, found using “ip route” or “route -n” command.
[root@vps-eb960963 network-scripts]# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 144.217.12.1 0.0.0.0 UG 0 0 0 eth0 144.217.12.1 0.0.0.0 255.255.255.255 UH 0 0 0 eth0 [root@vps-eb960963 network-scripts]#
Create a static route file
vi /etc/sysconfig/network-scripts/route-eth0
Add
144.217.12.1 dev eth0 default via 144.217.12.1 dev eth0
Here 144.217.12.1 is the gateway IP address found in the above step.
