IP Address adding issue due to RTNETLINK error

Hello, When I try to add IP to my WHM server I get the following error

Error warning The “/sbin/ip -family inet addr add xx.xx.xx.xx/29 broadcast xx.xx.xx.yyy dev enp10s0f1np1 label enp10s0f1np1:cp1” command (process 146609) reported error number 2 when it ended.: Error: Attribute failed policy validation.

The “/sbin/ip -family inet route add xx.xx.xx.xx dev enp10s0f1np1” command (process 146610) reported error number 2 when it ended.: RTNETLINK answers: File exists.

Please give me a solution.

Thanks

    It seems the IP is already added. You can check it using "ip a" command from command line.

    When I try to add IP via Add a New IP Address in WHM it gives the error, I can see the IP address entry in /etc/ips. However not in "ip a" in command line.

    This is the issue and the solution:

    https://support.cpanel.net/hc/en-us/articles/1500007799001-Cannot-add-IP-in-WHM-due-to-RTNETLINK-error

    The kernel has a hard limit of 15 characters for the name of an interface. If your network interface has a long name, adding additional IPs will try to add 4+ characters to the name of the base interface, starting with ":cp1" and incrementing for each IP. If the name of your interface + the additional label exceeds 15 characters, the system will be unable to add the interface.

    I saw that link and tried to fix the issue by using the following command

    ip a add xx.xx.xx.xx/xx.xx.xx.xx(subnet mask) dev enp10s0f1np1 

    the IP is added, can be seen in the whm but I don't know if it is the correct procedure or not.

    You need to change the interface name "enp10s0f1np1" to something shorter to fix this.

    Changing the interface name may vary depending on your server's configuration, but it isn't something that can be done inside cPanel.  You may want to speak with your specific provider to see about the safest way to change this without disrupting the service.
