Hello Chuck!
I have 128kbit/s for 70 computers and if several users
start several FTP/HTTP/Torrent downloads (or one downloads with
several threads) or also open several htmlpages with big content,
for other users remain not very much.
As i hear Squid make traffic shaping on IPaddress base and in
my scenario every user will work in equal borders (as another) for
all his connections.
Can we do such with 'tc' utility?
Sorry for question not exact for this maillist.
Thank you very much!
Alex
