Networking :: Limit Downloads Without Speed Loss?
Mar 20, 2011
We (3) have download limit problems with a 50G/month limit (Inc uploads). The router I cannot change, and it offers no useful options. So I am considering using IP forwarding from my own box. I think I would need a second nic, & router. Eth0 would run a dchp server, eth1 would run a client. What do I run on the box to monitor downloads & uploads, and is there a way of adding pc & laptop downloads to limit luser downloads? Does this stuff strangle speed? I'm running slackware-13.1

I just switched from XUBUNTU to fedora 10 and have to say I will most likely change back. Unless someone can tell me how to speed up the internet connection in fedora. I have tried wireless and wired and it doesn't matter which I use the download rate is painfully slow. With wired I get a meg every minute. It really hurts to watch the monitor.Downloads for three seconds then takes a break for eight seconds then downloads for three more seconds and this goes on and on. I have a very fast connection and am used to getting amazing unbroken streams of data at no less than 1 meg every 2 seconds. I hope this is a rectifiable situation.

PC running Ubuntu 10.04LTS, with a Virgin media modem NTL250 with a Buffalo Airstation Turbo G wireless router running Tomato Firmware v1.27.1798.The router is is used by a Internet radio, a wii (both full time) and a nokia N86 mobile and a PSP (used occasionally). The PC is connected by a network cable to the router.Now, when the modem is plugged directly into PC i get 6 to 8 Mbs download speed. When I go modem to router to pc the speed drops down to 512 to 824Kbps. Speeds were obtained off of broadband.co.uk speed tester.

I have problems with my network speed when i ping my proxy server I end up getting a high packet loss generally more than 30%.I have tried to use various network monitoring softwares like etherape, wireshark, tcpdump but I am not able to get to the bottom of the problem.basically I am trying to find out where the lost packets are going.

I have a linux debian on a network connected to a router through a ethernet cord. My linux is hogging the network speed and the users of the other computers on the network aren't very happy. Is there a way to limit the download speed on only my computer?

I need a program that will limit download speed per connection. So that each download is limited to 100kbit/s for e,g. I tried trickled, it only limits whole application (and doesn't work with firefox). Also tried pyshaper, doesn't work. Is there such software?

My DVD player attached to my TV is picky. Burn CD's (with avi files) at 8X and it plays them. 16X and it complains about bad disk. Every time. In karmic, I can only get cdrecord to burn at 16x.
Here's the command:
cdrecord -dev=/dev/scd0 -speed=8 -dao -pad -v something.iso
And it burns at 16x instead of 8x. Command issued with root privilege. Identical hardware under CentOS 5.x and it burns at 8x, like I asked it to. I'm all SATA if it matters. What do I need to do to get the version of cdrecord with karmic to burn a data CD at 8x? For whatever reason, CDs burned at 16x just don't work in the DVD player attached to my TV.

I am trying to limit bandwidth of certain ip addresses on my server. I have been doing hours of reading and not getting very far... So far I believe the iptables command is
ptables -A PREROUTING -s 178.33.23.44 -t mangle -j MARK --set-mark 2
ptables -A PREROUTING -s 178.33.23.45 -t mangle -j MARK --set-mark 2
ptables -A PREROUTING -s 178.33.23.46 -t mangle -j MARK --set-mark 2
ptables -A PREROUTING -s 178.33.23.47 -t mangle -j MARK --set-mark 2
and now I just need the tc command to read those marks and limit bandwidth, I have a gigabit connection and would like to limit each of these ip addresses to 10mbit in and out.

I use vsftpd. I would like to know if there is a way to limit the upload speed. Only the upload speed so the "anon_max_rate" and "local_max_rate" don't do the job. Someone told me about the trickle but I expected a more recent application.

It sounds weird but on Linux I can't find a browser that allows to set a download speed limit. I found an extension for Firefox but it works only on Windows. I know the existence of download managers like d4x, wget, jdownloader, etc... but some downloads can only be done by browser. I know trickle too but if I want to change the speed limit I have to 'restart' the command (interrupting the current download). Then I didn't find an extension for Chromium.

Is there a way to limit the speed that apache will send a page to a specific computer in my LAN? I would like to be able to test what my pages would be like if they loaded at 25KB/s for example. My Server is 192.168.0.2 and the other 'browser' computer is 192.168.0.4.

In my household a number of people use the internet. Up to a maximum of 3 wired connections and 2 wireless connections at its peak, all connection through my D-LINK G604T router. The problem is, when one person is downloading or watching ..... or whatever, the others using the internet suffer. I've spent hours configuring QoS on my router, and long story short, no matter how I configure it, it just simply does not work. QoS in no way shape or form limits connection speed (which it says it should). Anyway.
I have a spare computer under my desk, and I'd like to know if I could set this up with a (free) linux distro that limits bandwidth speed per connection. For example, of the 1500 kb/ps (about) my modem pulls, is there a way to limit that to 768 or 512 per connection? so person A can still download, person B can still watch ....., and person C can still play counterstrike with a latency under 100. This would solve many, many arguments in my house I am *fairly* good with computers, but if the distro came with documentation and a GUI that would be awesome.
* TL;DR: *
Is there a linux distro I can load on a spare computer that limits bandwidth per connection, wireless or otherwise, with good documentation?
Failing that is there firmware I can use for my modem (dlink g604t) that would do the same?
Failing that do you know of any good hitmen that would solve my family arguments, ahem, permanently?

I have this new flatmate who uses all my Internet data up before the end of my monthly clockover. Instead of having to buy heaps of data top-ups at the end of the month, is there a way I can limit the speed of his computer through the network? I have tried looking through my router settings (which is a Thomson router) but there doesn't seem to be any options in regards to limiting activity of a system on the network.

I have a PC that is using Ubuntu Karmic. It serves only to download stuff, and is on 24-7.
Can I set a limit to download speed for Deluge and aMule throughout the day (so that it doesnt interfere with other network stuff) but unlimited during the night? (when we are all sleeping)

I have 3 Dell Precision M4400 machines. After getting updates yesterday or today, I get random network dropouts like crazy, on wired or wireless. On one machine I was able to turn off ipv6 in grub and reboot, and it works now. However on the other 2 machines, still have the same problems. All 3 are running 9.10 64 bit. Is there a way I can back out the updates so the network works again? Anyone else see this behavior after updates today?

I am simulating a TCP/FTP to TCP/FTP network and trying to monitor the packet loss.
I am able to monitor and graph data regarding the TCPSinks' bytes received, but I can't monitor packet loss.
Why is it that the TCPSink Agent has a variable for bytes (bytes_) but not one for monitoring packet loss?
Do I have to monitor the packet loss from the queue? If so, how do I write code for this?
Below is part of the code for monitoring bytes received from sinks if anyone was interested.

I have a new Toshiba Satellite L450, and decided to run Ubuntu, which is new to me. I am running a 64 bit Karmic, and there is no driver that works. So, to make a long story short: a friend helped me get a driver on my Desktop, namely: rtl8192se_linux_2.6.0100.1012.2009_64bit.tar.gz We had it working, but when I let in the first large batch up updates, it kicked the driver out. I found instructions, installed it again. I let in the next updates, and it kicked out again, and this time the instructions don't work. So, I have two sets of questions:
1. Will updates always undo my wireless? Are there certain updates I should avoid if I want the wireless to stay up and running? (I just assumed the thing to do is just get the updates -- though I am guilty of having no idea what they were about.)
2. Did the updates cause one of my instrucitons to no longer work, or need to be modified?
They were as follows:
sudo apt-get install build-essential
cd ~/Desktop
sudo tar -xvzf rtl8192se_linux_2.6.0100.1012.2009_64bit.tar.gz
That 'sudo tar -xvzf...' operation is the one that stops me. Is there something to change in that line? It goes on:
cd rtl8192se_linux_2.6.0100.1012.2009_64bit
[Code]...
this worked the first time I tried it. I posted this earlier under 'hardware', and do not know how to get that post off, so I typed it here once I realized.

I am just starting my adventure into Ubuntu. After installing and configuring Shrew Soft in Ubuntu 10.04 64Bit, I am having some serious packet loss issues. The LAN is wireless, however the only packet loss I experience is over the tunnels. I have tried different algorithms, and it seems as I fiddle with the MTU client side, it clears a bit, but the best I have managed is 23% loss average.

I try to setup a locale network between 10 (Web) Servers (openSuse 11.2), each Server is connected to the internet (eth0) which works fine on all servers.
A 2nd NIC eth1 (1GBit rtl-8169) on each Server is connect to a Switch and should function as a LAN. I installed/configured the 2nd NIC with yast, and than added a route for the local network (192.168.20.0) to use eth1. So far every thing works (ssh for example), but I have a packet loss of 10%-60% (ping) on the local network, and I cant find the reason for the packet loss. I already installed a Debian Lenny on 2 Servers (just to test) but I have the same problem on Debian.
No firewall or any other application is in the way. With tcpdump I could figure out that the packages are send but never show up on the destination server.
I put some more information about how I configured the LAN below. I have not done this my first time and from my experience if something is wrong with the network configuration (wrong routing, firewall in the way, etc.) this usually leads to a packet loss of 100% or the destination is simply not reachable.
The 2nd NIC is installed with either yast on suse , or by editing /etc/network/interfaces on debian. The Kernel module rtl8169 is loaded.
They are configured with the following values:
Route is added by:
Output example. of ifconfig :
Output of route (same on all servers):
Output of ping:

I have a VPS server with 512 MB memory. The php.ini is set so script memory limit = 16 MB. However, I have noticed in my top report, instances like the following:
Quote:
5484 coldclim 25 0 46476 32m 5920 R 0.0 6.4 0:00.93 php
The bold number of 6.4 is the % of sever memory this process is using. 6.4 % of 512 MB of memory is about 32 MB of memory, so it appears that this isn't being limited by php.ini. Am I correct? This leads to the next question: Is there some way to limit the amount of memory a single suphp process can use? (Basically, something like the setting in php.ini which limits suphp processes in the same way.)

The problem is I have a wireless Belkin router which I can connect to, but after being connected for a few minutes the net disappears (cuts from the router) and my laptop will have to reconnect again to the router for internet to work again. After a few minutes (or seconds in some cases) the connectivity loss will happen again over an over.
How to fix this problem or some things I can try, I've tried updating to two different firmwares, two different channels and resetting the router. The biggest problem I find is that this happens on both my laptop, another laptop in the house and also my tablet PC but doesn't happen on two other laptops in the house, I've also tested with windows 7 and Ubuntu with my laptop.
My laptop wireless card is Atheros AR9285 802.11b/g/n WiFi Adapter

I have a hp dv3 laptop which dual boots Win7 and Ubuntu 9.1 64 bit. I have no issues with my wireless adapter in Win7, but I lose connection after a couple of hours in Ubuntu. When connection is lost it is not possible to view any wireless signals, the adapter is basically turned off. The only way to restore the connection is to reboot, then Ubuntu will again automatically connect to my WP2 encrypted router. My wireless adapter is a AR928X made by Atheros.

For most of today I had my internet connection dropping out on me intermittently. I assumed it was a provider issue, as it has been unreliable in the past. After it dropped out for good, and I could not print through network, I realised it was not a provider issue. All the other computers in the house were connected, including another ubuntu box. Only the MacBook Pro 5,5 was not able to connect. The network manager indicated I was connected to the network, throughout the whole time.
A number of restarts with the kernel I normally use (2.6.31-19) including one in recovery mode, yielded no change, but a restart with the 2.6.31-20 kernel resulted in connectivity. Finally, perhaps by chance, wireless started to work again on the 2.6.31-19 kernel, after I once booted into the Mac OS, and then back into Karmic. How I might go about diagnosing, obviously in hindsight, what happened? I suppose I should look in the log files, but I have no idea where exactly, and what to look for.

I got a new X201 which is running Ubuntu 10.04. While at home, everything is fine, at work, I encounter some issues with wireless. the signal cuts in and out repeatedly.Here's the output of ping. I set it to ping a server every 90 seconds, 10 times. So this is a snapshot of 15 minutes of network activity...
Code:
PING (REDACTED) bytes of data.
64 bytes from (REDACTED): icmp_seq=1 ttl=252 time=1.50 ms
64 bytes from (REDACTED): icmp_seq=2 ttl=252 time=2.13 ms
64 bytes from (REDACTED): icmp_seq=3 ttl=252 time=1.38 ms
[code]....
Also I tried this (from a 2 year old thread which was most relevant solution I could find):
Code:
Changing AVAHI_DAEMON_DETECT_LOCAL=1 to AVAHI_DAEMON_DETECT_LOCAL=0 in /etc/default/avahi-daemon has got rid of the irritating pop-up. Basically, every 5 minutes or so, for a solid 60 seconds or so I get no signal. I've tried updating the kernel, and doing apt-get remove avant-daemon, but still have problems.
