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

Hi All, Mails from Patrick''s account is bouncing back. Does anyone knows his alternative mail address? -- Sumit> -----Original Message----- > From: devik [mailto:devik@cdi.cz] > > > > [root@linux /root]# dmesg > > ... ... ... > > NET: XXX messages suppressed. > > Dead loop on virtual device gre1, fix it urgently! > > Hmm.

Hmm, Patrick had a big personal troubles when I talk to him last time. Maybe he is no longer able to read his mail :( devik On Wed, 30 Oct 2002, Sumit Pandya wrote:> Hi All, > Mails from Patrick''s account is bouncing back.
