Hi,
I have a fedora38 server that's been updated to new versions many times over the years. It seems now I'm having a problem with the static route I created many years ago no longer being supported. I knew this was coming, but I'm unfamiliar with the new methods. I'm using the old network-tools method, not NM or even nmcli.
It clearly doesn't understand my current config: Nov 16 15:25:52 mail03 network[1123]: Bringing up interface enp0s31f6: Nov 16 15:25:52 mail03 network[1313]: INFO : [ipv6_wait_tentative]

In /etc/sysconfig/network-scripts/route-enp0s31f6 I have the following: 192.168.1.0/24 gw 68.195.11.42 dev enp0s31f6
In /etc/sysconfig/network-scripts/ifcfg-enp0s31f6 I have the following
(my domain sanitized):
# cat ifcfg-enp0s31f6|grep -Ev '^$|^#' HWADDR=4c:ed:fb:bb:47:93 BOOTPROTO=static DEVICE=enp0s31f6 TYPE=Ethernet ONBOOT=yes IPADDR=68.195.11.45 GATEWAY=68.195.11.41 NETMASK=255.255.255.248 PREFIX=29 SEARCH="example.com" DOMAIN="example.com" DNS1=127.0.0.1 ZONE=FedoraServer NM_CONTROLLED=no
I'm also still using iptables, not firewalls or ipfw.
Ideas on how to "upgrade" my server would be greatly appreciated.
The first step you should do is to migrate the /etc/sysconfig/network-script to the NetworkManager standard configuration in /etc/NetworkManager. The /etc/sysconfig-method got deprecated some times ago and iwas withdrawn with F37 or so (don’t remember the exact release, it feels like it was soooo long ago). The network guys provided a nice migration tool which does all the work. Search the Fedora Magazine, there was an informative article about the migration process. (Just found it: https://fedoramagazine.org/converting-networkmanager-from-ifcfg-to-keyfiles/). The migration tool migrates the static routes, too.
In case of difficulties, feel free to ask. Maybe on our Fedora Server mailing list.
This was a big help, thanks. The only thing it didn't do was migrate my static route. I installed NetworkManager-tui and used the text interface to add it manually. Now that I see what I did, I could probably do it again manually.
I'll also join the Fedora Server mailing list after all these years.
