 |
|
Until recently I was running a Gentoo machine that was extremely outdated. Since I was unable to updated it, I did a fresh install. Everything went smoothly until I started configuring iptables. My old rule sets throw errors they never used to. I was able to narrow it down to the LOG chain.
Running the following script:
| Code: |
/sbin/iptables -N LOG_DROP
/sbin/iptables -A LOG_DROP -j LOG --log-prefix "iptables drop: " --log-level 7
/sbin/iptables -A LOG_DROP -j DROP
|
Results in the following:
| Quote: |
iptables: No chain/target/match by that name.
|
I've tried researching the problem but I've come up dry. Any suggestions? |

Make sure you have the LOG target enabled in the kernel. Since you did a fresh install, you likely have a new kernel, and it may not have that option enabled. I've stubbed my toe on this multiple times.
Do a kernel config/build with your method of choice (i prefer genkernel, but there are arguments both for and against); reboot into the new kernel and you should be good to go.

| You were right. I compiled the relevant module and it works perfectly. Thanks! |

Great! Glad to help.
If you could add a "Solved" to the original post's subject, maybe others will find it useful, as well.
