Summary:  Upload limitation does not work

Original Submission:  Hi,

I live in Germany and can only upstream with 16KB/s (capped by the German 
Telekom).

And if I set my mldonkey-upstream to 15 I am experiencing the problem, that 
mldonkey does not stick to its limitation, it always tries tries to send more 
than it can send and my Provider then allways disconnects me.



I am using mldonkey 1.16

I was just evaluating mldonkey. It has been running > 15hrs now and just NOW I 
am experiencing the same problem with upload larger than it should be



The problem is, upload limiting *does* work for transfers but I just took an 
"out-time" with "nu 60" and still I am exceeding 14+KBytes / sec. Then I went 
to look with a network sniffer on the linux server and I saw that mldonkey is 
NOT uploading a single file. However, it IS asking many many peers for files. 
All packets are around size 15, 30 and 60 bytes, so very small. But there are 
SO MANY of them that it saturates my upstream !



In short: mldonkey (version 2.0 release linux shared binary) seems to cap 
uploads but not meta-data/search upstream



I have an ethereal packet dump of a few seconds where mldonkey shows this 
behaviour. If the developers want it, just email me at address@hidden

poelzi meant, that you can create a single account only for mldonkey, and shape 
the traffic for this account (eg. "leech"). Well , it works for me :)

well, just set it the uprate value to 5 as i did.

iptraf says outgoing rate is about 9-10kbyte/s, which

doesn't actually fit in the limitation, but my remaining 8kbyte/s bandwith is 
enough to manage other tcp/ip stuff

Darn, Even with the 'new' 2.0 so called 'stable' release this bug has not been 
fixed!

I set the cap to 10KB, but the §$%§! thing just ignores it and pumps out at 
20KB at this point my provider disconnects me.



And please do not tell me to limit my overall-output like poelzi tried as I 
have more than one process on my box that needs some bandwitdh



Thanks

I use 

http://fiaif.fugmann.dhs.org/ firewall and patched them for adding own rules. 
The patch is padded for adding into the distrbution but can get it from

http://files.poelzi.org/patches/fiaif/addbands.tar.gz



good look :)

When you use Linux you can use for example:

iptables -I INPUT -i ppp0 -t mangle  -m owner --uid-owner leech -j MARK 
--set-mark 67



Then run every P2P program as user leech. Every outgoing packet is marked and 
can be shaped by a tc rule to one limit.

Don't forget to use a qos qdisc and not only a class or mostly the wrong 
packages get droppend an transfer is realy bad. I have good experiences with 
tbf as qdisc.

I live in Germany too. I experienced a few problems while testing mldonkey. The 
first one was , that mldonkey uses too many connections if you want to share 
the line with a few workstations. 5 PCs online at home here. If mldonkey runs a 
while nobody can even surf anymore. limit the connections to 200 or 300. QoS is 
a way to limit upload bw, BUT it limits (and if to fast drops) the p2p 
communication packets too (because they use the same port) and thats not what 
we want. I think it is the 900+ connections too, that is causing the uploadbw 
"override". To hold the connections a few kb/s are needed and to establish new 
ones even more bw is needed. Im not sure if mldonkey calculates this. So reduce 
the maxconnections value. Further i noticed a random disconnect. The first 
thing i thought its my ISP disconnecting me, because i cant do to many nmap 
scans without beeing disconnected. But this wasnt the case. I looked in the 
debugmessages of my clientsoftware ( rp-pppoe ) and saw a message like "net 
send error ... no buffer space availabe ... modem hangup". Its a bug in the UDP 
packet handling of the pppoe software. Its easy to fix. You just have to edit a 
line in the sourcecode and recomile it.

Sorry, I dont have the link anymore but I found the solution at the debian BTS. 
www.debian.org . The error appears if sending many UDP packets. (eg extended 
search).

Sorry for my bad english.

max_hard_upload_rate = 15 works fine with me...

a workaround for users that are deconnected by their own provider would be to 
use QoS to limit bandwith usage on donkey ports.

update (me again)

just read the releasenotes of mldwatch 1.7 and found a bug report on the 
up/down speed shown in the statusbar.



unfortunateley this does not have anything to do with the problem of too high 
up/down rates i experienced

update concerning my post from 2002-Sep-16 02:39 (the huge one) : it's not only 
the downstream bw that's completely sucked up by mld, even the upstream is at 
128kbit/s.

-

sure @ mldonkey, now i updated to mld1.99b8 and mldwatch 1.7.

the gui pretends to upload about 3-4kbytes/s with a given limit of value "10". 
[kilobytes per second, aight? ;) ]

but iptraf shows me an output bandwith of about 135 kbit/s.

(yes i checked iptraf even when mld was offline, and it was about 8kbit/s).

maybe it's not a transfer sucking up my bandwith, because mld found about 2600 
sources for one file, but i limited the value to 1000. could this be the reason 
why i have no bandwith left?

ppp0 receives 45000 packets per minute, almost 98% for mld.

Don't forget these options are in kB/s and not kb/s



Next CVS snapshot will indicate in the GUI the uploaded/downloaded bytes.

Hi

I use the same provider, and limitated my bandwith in mld 1.16 to 80/10 k/s, 
and it works pretty fine.

However, from time to time, my mld seems not to update his serverlist after 
restart (although 4 .met's are in the downloads.ini), and starts starving 
around with about 40 servers.

So i used the mld 1.99 beta5 core (just because of the nice windows-gui that's 
around),and now it seems to me that mld 1.99 has severe problems with bandwith 
limitation.

mld1.99 always seems to suck up the whole downstream bandwith, no matter which 
limit is set.As my linuxserver is used as a router to, it comes extremely 
unhandy that there's almost no downstream bandbwith available (even 
smallhonkclients like irc or icq can't connect to their servers - same applies 
to the browsers.)



have a nice day

I have it too, it´s fucked up, because my hole house is on a router, and when 
mldonkey is running, the other computers can´t surf in the Internet!!!!

I have the same problem!

Got the same problem. I temporarily fixed this with a smart router (Basically, 
I drop incoming frames when the bandwidth limit is reached). This is not the 
right/intelligent way of doing it. I would really like to get this one fixed.

y0, got t-dsl too and have the same prob

got upload on 12K/Sec but its streaming more than 16K/Sec

:/ fix that plz
