IP Transfer Swap and reboot still shows old IP address
In Atlanta, I swapped two Linode machine IP address.
linode1 (45… IP address) This is my public machine and in DNS
linode2 (173… IP address) I built a new machine here.
Then I did the IP swap, and it worked half-way:
linode2 is now at (45… IP address). This is good, and the is publicly accessible web and other resources.
But I need to keep the old machine around for a few more days.
And I find I cannot ssh into it.
Linode manager says it has the new 173… IP address, but connections to that address time out.
I can use the could Lish console, and it shows that internally the machine still is holding on to the 45… address, even after a reboot.
"ip a" shows 45….
Is this expected? Do I just have to wait a few hours for the old machine to get the new address shown in the cloud.linode.com console?
To close this issue, turns out the IP Swap failed to fully complete it works correctly.
It only worked partially. Reboots did not fix problem, nor did waiting 12+ hours.
So support said best fix is to use static IP assignments, so did that, and now all is fine.
Followed instructions here:
First, disable the automatic network helper.
