[Bug 1729] New: iptables list shows proto column with numeric instead of protocol name
https://bugzilla.netfilter.org/show_bug.cgi?id=1729 Bug ID: 1729 Summary: iptables list shows proto column with numeric instead of protocol name Product: iptables Version: 1.8.x Hardware: x86_64 OS: Fedora Status: NEW Severity: enhancement Priority: P5 Component: iptables Assignee: netfilter-buglog at lists.netfilter.org Reporter: btanastasov at yahoo.co.uk Hello, Couple of days ago I found that on Fedora 39 there is a change in output of: iptables -L -vn I'm using those options for many years ... more than 20 or so on many computers with older/or stable versions, but on my desktop which I upgrade regularly I don't run it very often, because the config is the same all the time. I just upgrade the machine and the firewall script I have is started at boot. I managed to find that the change I'm writing to you is made around update iptables between 1.8.8 and 1.8.9. This is the commit: author Phil Sutter <phil at nwl.cc> 2022-07-28 12:31:36 +0200 committer Phil Sutter <phil at nwl.cc> 2022-07-29 11:53:54 +0200 commit da8ecc62dd765b15df84c3aa6b83dcb7a81d4ffa (patch) tree 1f1f4503f9bf6d600fa0fa9921a160af3f45b2e7 parent ba98dc47073b46c3a514039baaddcebecb4e738d (diff) xshared: Print protocol numbers if --numeric was given This is much trickier than expected: On one hand, proto_to_name() is used to lookup protocol extensions so must resolve despite FMT_NUMERIC being set. On the other, --verbose implies --numeric but changing the output there is probably a bad idea. Luckily the latter situation is identified by FMT_NOTABLE bit. Signed-off-by: Phil Sutter <phil at nwl.cc> This is backported in Fedora 38 too (iptables is the same version 1.8.9). With this commit the output of iptables -L -vn (--numeric included) is changed. Now the proto column shows numeric 0, 6,17, etc., instead of protocol name: tcp, udp, all etc., compared to all previous versions. Without -n output is very slow, because of DNS resolving. I think it is useful to revert this change, because as is with column "target" it is more descriptive. I didn't find option to change the proto column to name, so I'm writing to you.
