Hi Devik/Patrik,
In setting up IMQ/HTB with a GRE Tunnel I'm constantly getting kernel
errors:
[root@linux /root]# dmesg
... ... ...
NET: XXX messages suppressed.
Dead loop on virtual device gre1, fix it urgently!
... ... ...
This I get only if I'm going to start cross device b/w control. If I remove
iptables rule
iptables -t mangle -D POSTROUTING -j IMQ
then no such warning messages :O.
An information to this is in my all class I'm using very low rate and rely
on ceil parameter of htb... example of one such class is
class htb 1:35 parent 1:2 leaf 35: prio 0 rate 1Kbit ceil 64Kbit burst 1600b
cburst 1680b
becouse of that I get following message on console
... ... ...
Oct 29 17:30:12 1035892812 kernel: HTB: quantum of class 10057 is small.
Consider r2q change.
Oct 29 17:31:08 1035892868 kernel: NET: 17 messages suppressed.
... ... ...
This I didnot think a serious matter as in your code you yourself concern
and at run time adjust that parameter and also this works with ethernet
without any problem but while using gre I get dangerous(seems to be)
warnings flooding up.
Any Idea about this? I'm using RedHat release kernel-2.4.18-3 with your
patches
imq-2.4.18.diff-10.txt and htb3.6_2.4.17.diff
In case if you need my detail network setup configuration...
My Tunnel configurations are following
LOCAL-IP=202.LLL.IP.148
REMOTE-IP=202.RRR.IP.4
TUNNEL-IP=202.TUN.IP.254
