Red Hat Bugzilla – Bug 4922
IP/MAC address conflict at boot when shapeing windows pc
Last modified: 2008-05-01 11:37:51 EDT
I am running the traffic shaper which comes with RedHat 6.0
and it works great, except that if a windows 98 machine is
being shaped, and that machine reboots while the host shaper
route is defined, then the windows box will detect a
conflict for the IP address. This then causes the windows
machine to boot up with the network interface disabled.
The machine doing the routing/shaping is a dual processor
system running the smp kernel (of course). All linux
software is out-of-the-box stock official RedHat, nothing
The following are the commands to setup traffic shaping.
Everything works OK until the last statement where the host
route is added. After this point, the problem mentioned
above occurrs. If that host route is deleted, then the
problem goes away.
/sbin/insmod shaper -o shaper0
/sbin/shapecfg attach shaper0 eth0
/sbin/shapecfg speed shaper0 20000
/sbin/ifconfig shaper0 192.168.110.1 netmask 255.255.255.0
/sbin/route add -host 192.168.110.222 dev shaper0
The address 192.168.110.1 is the IP address of the nic in
the linux router, and 192.168.110.222 is the win pc being
shaped. I am doing something wrong here, or is this a real
bug with shaper?
Is this still a problem in 6.2?
Or in the pinstripe beta?
OK - no information to the contrary, I'll close this as "fixed for Red Hat 6.2"
