Hi,

   1.By default which delay distribution is used by NetEm ? Is it normal or uniform?
Ubuntu man page and many webpages stating that normal distribution by default, But 
kernel function tabledist in net/sched/sch_netem.c telling uniform distribution 
by default. I am still confused about this.
   2.I tried to run following command :
tc qdisc add  dev eth0 netem delay 100ms 10ms distribution uniform
I got,
No distribution data for uniform (/usr/lib//tc//uniform.dist: No such file or directory)
Segmentation fault

Any suggestions would be appreciated.
