Ello all,
I've just been playing with ipfw trying to get weighting to work. My end
desire is this - make ssh lag-free regardless of what else is going on -
ftp traffic being the worst offender.
So I set out with this:
ipfw add queue 1 ip from $LOCALNET to 195.11.55.73
ipfw add queue 2 ip from $LOCALNET to not 195.11.55.73
ipfw queue 1 config weight 100 pipe 1 mask src-ip 0xffffffff dst-ip 0xffffffff
ipfw queue 2 config weight 1 pipe 1 mask src-ip 0xffffffff dst-ip 0xffffffff
ipfw pipe 1 config bw 0
right at the top of my firewall sh script.
I was hoping this would give top priority anything going to 195.11.55.73,
and bottom priority to anything not going there.
The output of ipfw pipe show looks correct - I can see a connection to
195.11.55.73 from my box (which happened to be ssh)..
q00001: weight 100 pipe 1 50 sl. 1 queues (64 buckets) droptail
mask: 0x00 0xffffffff/0x0000 -> 0xffffffff/0x0000
BKT Prot ___Source IP/port____ ____Dest. IP/port____ Tot_pkt/bytes Pkt/Byte Drp
16 ip 195.11.8.226/0 195.11.55.73/0 90 5456 0 0 0
q00002: weight 1 pipe 1 50 sl. 41 queues (64 buckets) droptail
mask: 0x00 0xffffffff/0x0000 -> 0xffffffff/0x0000
BKT Prot ___Source IP/port____ ____Dest. IP/port____ Tot_pkt/bytes Pkt/Byte Drp
2 ip 195.11.8.253/0 63.197.148.248/0 10 910 0 0 0
4 ip 195.11.8.226/0 193.216.39.123/0 2 68 0 0 0
You can also see there were other connections accumulating in q00002
(there were many more) so that part appears to be working - the right
connections are going to the right queues.
What doesn't work is the weighting itself. I saw absolutely no difference
whether I had those rules in or not.
What am I missing?
If you need any more info please shout.
Thanks in anticipation.
