License verification using wrong IP

    Hello @Stavro, You can see which IP address your server is making outgoing connections from with one of these commands: curl -L http://cpanel.net/showip.cgi lynx -dump http://cpanel.net/showip.cgi
    If you need to change the IP address used for outgoing connections, then you'd have to make manual modifications to the network scripts on your system. Here's a thread where this is discussed:

    Thank you for the reference, but it didn't really help my situation. Edit /etc/sysconfig/network-scripts/ifcfg-eth0 This file remains at the proper values. 145.63 is still the main IP. Edit /etc/sysconfig/network The default IP is still 145.63, and the default gateway is still 145.1 Edit /etc/ips This file is blank. Since the instructions are to remove the new IP, I'm unsure if I should add the main IP, or leave it blank. Edit /var/cpanel/mainip The default IP is still 145.63 Edit /etc/hosts 145.63 is still listed as the hostname IP. All services have been restarted, though I don't see the point as no files were changed. And ifconfig still shows 145.63 as the primary IP, attached to eth0, with the secondary IPs attached to eth0:0 and eth0:1. curl -L

    Hello @Stavro, We typically avoid offering assistance with modifications to a server's network configuration because that's considered to be under the scope of a system administrator, however I'm going to try to point you in the right direction since this a common change. I found a link with a solution that seems to address the exact issue you are facing: Centos configure outbound IP address Can you let me know if that helps? Thank you.

    I understand the policy, but I respectfully disagree that issues directly caused by a cPanel update should be outside the scope of cPanel support. My server was working perfectly fine before the update, and none of the network configuration files have changed at all, it was the update itself that caused the issue. The ip route show command from your link shows that the default outgoing IP is 1.2.145.63, as it has been all along, yet the licensing server is still reporting back with 1.2.199.51. On the advice of my hosting provider, I'm going to migrate my sites to another VPS, wipe this one, and reinstall/update cPanel. If the issue occurs again, I'll repeat the process and try to determine exactly which of the cPanel update packages is causing my IP to switch.

    Hello @Stavro, I've added a note to the support ticket explaining this happened after a cPanel update so we can investigate to rule any cPanel-related issues that may have caused this to happen. If this is okay, could you reply to the support ticket to confirm that you want us to take a closer look (I don't want to interfere with an active migration if that's something you've already started). Thank you.

    since this is a VPS the network is likely being reconfigured by the VPS control panel back end on reboot check your eth0:0 & eth0:1 @ /etc/sysconfig/network-scripts and see if it adds the GATEWAY= line if it does remove the gateway lines from your 2 alias ip's and restart your network and see if your issue goes away Linux likes to go outbound on the lowest number ip address when there is a gateway listed in all eth0 devices in this case .51 since your IP's are on 2 different subnets there was no need to wipe anything it will likely do it again at some time if you have IP's on different subnets

    Hi I have a similar issue In our Dedicated Server we restored the Server from Cpanel Alamalinux Image yesterday. Our server has 3 IP Addresses: 135.181.136.169 (Primary) 135.181.136.141 135.181.136.142 The Cpanel license is Valid on the primary IP i.e 135.181.136.169 After the restore somehow the Cpanel is checking for license on the second IP Address i.e 135.181.136.141 and failing validation and not allowing WHM / CPanel Access. Please help us fix this as we cannot access our WHM and clients cannot access their cpanels. I have already created a ticket. Regards Amit Kalra

    I have created a ticket now # 95078260 For now we have closed the two secondary IP Addresses with these commands ifconfig eno:cp1 down ifconfig eno:cp2 down and now the outgoing calls are going out from the correct main IP Address. # curl -L 135.181.136.141

    We got a response from Cpanel Support Ticket #95078260 The issue happened because the Netmask was incorrect for the One Primary and 2 Secondary domains. In fact for all three IP Addresses the correct Netmask was 255.255.255.192 but it was configured wrongly as 255.255.255.255 I could delete the 2 Secondry IP Address and Add them again through the correct Subnet Mask in WHM-Ipfunctions The primary domain is being used for all 46 Client domains and the first name server too. I am just exploring the best way to fix the Netmask of the primary domain. I have updated the ticket with Cpanel Level 3 Support. Any ideas on what would be the best way to get this done. Through WHM it won't be possible to delete the IP as it is primary and in use. If we change the Netmask after connecting through SSH through the Secondry domain will be remain connected ? Regards Amit

    I would not expect that altering the netmask would take the domain offline.
