Is there any utility to limit the network throughput of a process after it has been launched? Simple example: you note that a user takes all your upload bandwidth using scp and you'd like to limit the rate or decrease the priority of the transfer.
I guess i could use a combination of iptables/tc or pf to achieve that, but i was wondering if there is a "one-shot" tool available (like trickle with a –pid option ^^) ?

On linux there is a way to limit network usage on a user basis:
I think there is no solution to limit the network utilization based on pid.
