Subject: one more... iproute commands lockup whole system
I'm not sure it is mistake or error, but i feel it is dangerous, cause
commands locking up the system, no kernel panic, no oops, so only watchdog
can save poor server (and not sure this even)
Commands to lockup system (just i am giving my example, i didnt sort out what
exactly locked up system, i guess redirecting to eth0.5, which is not
intended for that):
vconfig add eth0 5
ifconfig eth0.5 192.168.1.2 netmask 255.255.255.128
tc qdisc add dev eth0 ingress
tc filter add dev eth0 parent ffff: protocol ip prio 6 u32 \
match ip src 195.69.208.252/32 flowid 1:16 \
action police rate 64kbit burst 90k pipe \
action mirred egress mirror dev eth0.5
