I receive emails from apticron about available updates for my Ubuntu server. That's great so far, but in the email, there are 4 IP addresses listed where I expect only 2.
The two IP addresses I expect: my new IPv4 address and my IPv6 address.
The IP address I don't expect: my old IPv4 address and my new IPv4 address again (duplicate).
I can't exactly tell in how many places I changed from the old IP address to the new IP address, but it seems I forgot at least one place which is relevant for apticron. Any ideas in which files I should start looking for?
In /etc/apticron/apticron.conf, it says that it will use the
ip command to figure out the addresses. But when I run
ip addr, it shows only my new addresses, not my old one.
