I assume you changed src to dst in the match.
Yes I did this some time ago.
Are you testing downloads from the wan or hosted on the box doing the
shaping?
All downloads are coming from the WAN via eth1 - nothing else runs on
this box except NAT and shaping.
After an overrate download can you post the output of -
tc -s class ls dev eth0 | grep "parent 1:X" -A 4
changing the X in "parent 1:X" to one less than the last part of the
IP address of the test machine.
Results appended. Sadly everything seems to show zero bytes. I checked
that everything is flowing through the correct interface, and yes it
appears to do so. This box has 3 interfaces. eth0 is the one facing the
NAT clients, eth1 is the public internet connection and eth2 is a
management interface. Only ssh traffic to my workstation is flowing on
eth2. I see two-way FTP traffic flowing on eth1 (I am downloading large
files from an FTP server for testing) but on eth0, i only see traffic
LEAVING the NAT clients and entering my shaping box. I have no idea why
I don't see traffic with destination of the NAT clients. There is no way
that the traffic could be "leaking" around my shaping box - eth0 is
physically connected to a 5 port switch with my test clients on.
When I actually went to the console of the box earlier, there was
loads of output from your script echoed to the console, each one
saying that the quantum was too small and I should consider adjusting
r2q. I don't really understand what this means.
That shouldn't really hurt too much, to fix it you could ether add
quantum 1514 to each of the two child classes or r2q 2 to the root class.
Adding r2q seemed to work.
FWIW I tried browsing with this setup and downloading aswell and it's
not very nice with such a long queue. An ISP/teleco would never have
that long a fifo on a 128kbit line. It would be better to add an sfq
to the bulk class or limit the length of the fifo.
Sorry for such a simplistic question - how might this be done? However
I'm not overly worried about making the quality of service perfect - I
just need it to be limited bandwidth. The reason why I want such a
restricted service is because the shaped NAT clients of this box are
going to be the "naughty" users on the university network who will have
their 100Mbit service reduced to 128kbit for a week as punishment for
rulebreaking etc. So if people complain about the occasional dropped
packet - they shouldn't have been downloading copyright material in the
first place!
