Subject: [LARTC] Semi-shaped traffic
Date: Sat, 21 Dec 2002 06:58:50 +0000	[thread overview]
Message-ID: <marc-lartc-104045399325537@msgid-missing> (raw)


  During my tests I'm starting to feel stupid :). Traffic
shaping works quite on its own.

  System: RedHat 7.3, RedHat kernel 2.4.18-18.7.xsmp, HTB
version 3.6, interfaces eth0 and eth1 are acting as bridge br0.

  If TCP shaping almost works, it just exceeds limits UDP
is not shaped. Traffic flows PC=>eth0=>eth1=>PC. Statistics
shown is for just UDP traffic (1mbit of small udp packets).
What strange is that I do not see dropped or overlimits
packets.

  Lots of info is at the end of the letter. Where is my mistake?

  Thanks,

  Mindaugas
