 |
|
I am trying to setup UFW, and I am getting some errors when I try to enable it. I enabled all of the necessary kernel modules from the wiki pages for iptables and ufw, but still no luck.
| Code: | ERROR: problem running ufw-init
Warning: Extension limit revision 0 not supported, missing kernel module?
iptables-restore: line 75 failed
Warning: Extension limit revision 0 not supported, missing kernel module?
iptables-restore: line 55 failed
Problem running '/etc/ufw/before.rules'
Problem running '/etc/ufw/user.rules'

See if you have
| Code: |
CONFIG_NFT_LIMIT=m
and
CONFIG_NFT_CONNLIMIT=m
|
in your kernel .config.Apparently you did not enable all of the needed kernel functionality for iptables.

| Thank you for your reply. Those were not enabled, but enabling them did not fix the issue. Also I meant to specify that only to my knowledge have I enabled all of the modules on the wiki pages, and some were marked as deprecated. |

You should
| Code: |
make menuconfig(find the symbols and enable them,then save the file)->make->make modules_install->make install->reboot

juliedeville,
What does show?
Are you running the kernel you think you are?
| Code: | $ uname -a
Linux neddy_static 6.13.0-gentoo #1 SMP PREEMPT_DYNAMIC Sat Jan 25 10:37:52 GMT 2025 x86_64 AMD Ryzen 9 5950X 16-Core Processor AuthenticAMD GNU/Linux |
The time and date, Sat Jan 25 10:37:52 GMT 2025 are the build time and date of the running kernel.
Yours should be nowish, if you have just done a kernel update and reboot. Does it look right.?

I find UFW module requirements a bit of a quagmire. The ebuild has several checks, though I'm not sure they're right. I haven't read the wiki items recently, so I won't comment, but AFAIR remember both those and the ebuild were insufficient. UFW supplies its own checker: | Code: | | /usr/share/ufw/check-requirements |
that might tell a more complete story, though I wouldn't put money on it!
