Hi,
I'm running a firewall with shorewall-4.6.3.4 (SuSE package) on openSUSE 13.2. Since about a week I receive lots and lots of messages like these:
Sep 15 09:37:32 proxy kernel: bsalg: parser failed Sep 15 09:37:33 proxy kernel: bsalg: parser failed Sep 15 09:37:33 proxy kernel: bsalg: parser failed Sep 15 09:37:35 proxy kernel: net_ratelimit: 2 callbacks suppressed
Last Kernel update was on August 18th, kernel-default 3.16.7-24.1. But the messages did not start immediately after this update. Shorewall is the original version included in the distribution.
This comes from net/ipv4/netfilter/nf_nat_snmp_basic.c and happens if SNMP requests can not be correctly NATed.
Open a bug agaisnt the kernel.
If possible, try to capture this SNMP network traffic that causes this problem.
Hi Marcus! Thank you very much for this hint!!!! :) :) This explains another problem I was having, and I can resolve it by using another router for this traffic. So: Problem resolved :)
Ciao, Marcus
