Re: cannot resolve host in VNET jail with RSS enabled

Hi, I've tested ng_eiface/ng_bridge work with VNET &. RSS. It's passed. But I'm not sure ng_eiface/ng_bridge weather or not get burst with RSS-enabled kernel. And seems that the bug is surely related to the epair driver. Simon 20220430 在 2022/4/13 00:51, Michael Gmelin 写道: On Tue, 12 Ap

cannot resolve host in VNET jail with RSS enabled

Hi, After kp@'s recently epair patch, I tried enable options RSS with Vnet jail, then found in these jail, 'ping 8.8.8.8' works as normal, and 'drill google.com' works ok. But 'ping google.com' nor other command fails resolving the host. Simon 20220410

How to disable tryforward ?

Hi, Tryforwad have merged 3 yeas ago, and it haven’t a sysctl to disable it , so ECMP was broken past 3 years. Olivier has fired a bug : https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=225792 , it seems that a few of people cares it. Andrey said maybe some ipsec policy can disable tryforward.

carp in the vimage jail

Hello Freebsd-net, Devd can monitor carp state changes on the host, but can not do this in a vimage jail. And the current version carp do not use carpdev, that means can not watch interface link up/down. How can I monitor carp state changes and trigger a external shell script ? Simon Ke 201

As a workround: Use one ethercard supports SR-IOV, then adds all the VFs to a bridge, bound each VF with a MPD5 instance and a cpu core. I have heard that PPP protocol support RoundRobin algo. But I have not tested it. Simon 20180728 在 2018/7/28 02:02, bugzilla-nore...@freebsd.org 写道: >

Re: epair failure in production on 11.1-STABLE (r328930) ? weird!

When the host boots, it hints set the epair queue max len to 86016. I did not see any related problem When I set it, it's stable. But epair consumed cpu, it's so easy to touch 100% cpu usage if it's passed high rate packets. Simon 20180703 On 2018/7/3 06:16, Bjoern A. Zeeb wrote: > On 2 Jul 2

in-kernel nat event log

Hi,lists, I would like to use ipfw in-kernel nat or ng_nat to replace my current iptalbe/netfilter nat. Netfilter provides an application called ulogd2 do export netfilter's conntrack record , does FBSD have similar solutions ? Regards Simon ___
