iH,
Installed openbsd 4.4 [VM on ESX] - Still seeing the same problem -
Using one of the pf faq examples - still can't figure out what I'm
missing:
OpenBSD openbsd.my.domain 4.4 GENERIC#1021 i386
# grep -v "^#" /etc/pf.conf |grep -v ^$
set skip on lo0
altq on vic0 cbq bandwidth 5Mb queue { std, ssh, ftp }
queue std bandwidth 1Mb cbq(default)
queue ssh bandwidth 500Kb { ssh_login, ssh_bulk }
queue ssh_login bandwidth 50% priority 4 cbq(borrow)
queue ssh_bulk bandwidth 50% cbq(borrow)
queue ftp bandwidth 500Kb priority 3 cbq(borrow red)
pass in quick on vic0 proto tcp from any to port 222 flags S/SA keep state
queue ssh_login
pass in on vic0 proto tcp from any flags S/SA keep state
pass out on vic0 proto tcp from any to any flags S/SA keep state queue
ssh_login
pfctl -vvsq shows the 'ssh_login' queue is being used.
doing sftp transfer over sshd on port 222 [just to isolate it]
traffic stays at ~250Kb, does not borrow
queue root_vic0 on vic0 bandwidth 5Mb priority 0 cbq( wrr root ) {std,
ssh, ftp}

Changing the parent 'ssh' queue to borrow:
# grep -v "^#" /etc/pf.conf |grep -v ^$
set skip on lo0
altq on vic0 cbq bandwidth 5Mb queue { std, ssh, ftp }
queue std bandwidth 1Mb cbq(default)
queue ssh bandwidth 500Kb cbq(borrow) { ssh_login, ssh_bulk }
queue ssh_login bandwidth 50% priority 4 cbq(borrow)
queue ssh_bulk bandwidth 50% cbq(borrow)
queue ftp bandwidth 500Kb priority 3 cbq(borrow red)
pass in quick on vic0 proto tcp from any to port 222 flags S/SA keep state
queue ssh_login
pass in on vic0 proto tcp from any flags S/SA keep state
pass out on vic0 proto tcp from any to any flags S/SA keep state queue
ssh_login
traffic pretty much uses up right near 5MB...
So not a FreeBSD issue it almost seems like it.
Have not tried OpenBSD mailing list yet.
I'm misunderstanding how pf/cbq should work?
