oops. I took bad classes (these clients where down so there was no traffic )
lately from tc -s -d class show dev eth0.
These are classes (part of) while there was no connection from clients.
BTW is it good tcng config with "fw". I mean if
fw {
class $classname on (2);
}
means "match packet to $classname if it's mark equals 2" ?
Is there any kind of sniffer or smth like that for tc? I mean to look in
realtime packet statistics. Smthing like iptraf maybe?
