Iptables xt_owner module missing

Help and Support Vero 4K / Vero 4K +
1

I’m trying to install an iptables firewall on my Vero 4K+ and I’m getting the following error when I try and use the owner module:

$ sudo iptables -m owner --help
iptables v1.8.2 (legacy): Couldn't load match `owner':No such file or directory

A little Googling says that the xt_owner module needs to be compiled into the kernel. Is it possible to request this to be added?

nftables think debain moved on to this instead of iptables.

Can you let me know the CONFIG_ option that needs to be enabled in the kernel and I will include it in the next build.

Cheers

I’m not 100% certain but here is what I came up with:

CONFIG_NETFILTER_XT_MATCH_OWNER

  • CONFIG_IP_NF_MATCH_OWNER
  • CONFIG_IP6_NF_MATCH_OWNER
  • Might be deprecated

I have recompiled the lastest Vero364 kernel(4.9.113-66-osmc) and tested it with the following two CONFIG statements enabled:
+CONFIG_NETFILTER_XT_TARGET_LOG=m
+CONFIG_NETFILTER_XT_MATCH_OWNER=m

Target Log allows iptables to send comment/debug messages to the system log and Match Owner allows iptables to match based on userid. These are the only two that I currently need and I would appreciate if you can add these to your next build.

I’ll get this added with the next video stack. Thanks for confirming.

This is updated and included in the next video stack
