Ubuntu :: Bandwidth Getting Lost / Wasted / Miscomputed By System
Feb 17, 2010
I recently installed Ubuntu 9.04 on a Fujitsu-Siemens Esprimo Mobile V5535 Laptop. It has an SiS 191 Gigabit Ethernet card, and an Atheros 5007EG wireless card. To begin with, the connection configuration was so bad I could only access Gmail and everything else was too slow to even work. I then came across a solution in a bugs page whereby I changed MTU to 1492 and the connection now actually works. Everytime a browser or apt-get makes a fresh connection request, it starts transferring data real quick 150-300 KB/s but then tails off exponentially, and within a few seconds is only bumping along at less than 1 KB/s. The fact that the initial rate is nice and then drops off is evidence to me that somehow the bandwidth is getting lost/wasted/miscomputed by the Ubuntu system.

I created a the class like this for shaping the packets with a specified bandwidth rate.....
tc qdisc del dev eth0 root
tc qdisc add dev eth0 root handle 1: htb default 15
tc class add dev eth0 parent 1:0 classid 1:1 htb rate 750kbit ceil 750kbit
tc class add dev eth0 parent 1:1 classid 1:3 htb rate 600kbit ceil 750kbit prio 0
For Our Requirement:-
I dont want to specify the bandwidth rate strictly like this rate750kbit ceil 750kbit,based on whatever speed is coming which should allocate the bandwidth rate for particular class...I need one application for finding the upcoming bandwidth & Is any other method is there for specify the bandwidth rate in a classes.

We have a sipmle office network set up that we also use use to connect to the internet, however of late the number of users has increased thus slowing internet access. Bandwidth upgrade is not an option thus i have to do bandwidth shaping on our linux router. The question is how do set the squid configs to allow certain IP's range a certain percentage bandwidtheg 60% and furthe divide the rest. Alternatively how can allow certain IPs to have higher bandwidth access.

the whole system seems to have lost its smoothness .. it looks intermittent whenever I maximize or move a window .. playing videos look choppy .. moving the cube is heavy.

I installed Lucid a week ago and have been having a blast with it after a two year break from Ubuntu (been using Mandriva). So the other day I went to hibernate the system and it froze. I naturally did a hard reset and when I log back in, no network connection. That is to say, the system tray says it's connected but there is no LAN light on the router or network card. ifconfig shows it's connected too. When I boot into XP (cringes) it works just fine.
No specifics ATM but the card is a D-Link PCI with a Realtek R8***** chipset

I have a server which is located in the basement. The server exports a few directories which I mount on my desktop using NFS. From time to time, the connection gets lost. The server is also not always on. I can't change that part, so I worked out a script which notifies me when it's going down, and when it's back up again. It also mounts everything back.However.. As soon as I loose the connection, my desktop seems to be gone. KDE doesn't work, but I can use a few applications like Konsole, google-chrome, firefox, stuff like that. But the plasma-desktop around it hangs.
As soon as the connection gets back again, everything works. I have this issue only when my desktop is running while I loose the connection to the server. If it's down when I start my desktopworks properly. Unless the server comes alive, the nfs directories are mounted and the connection is lost again.I'm not really sure if this is a networking case, it could also be KDE related, but I figured this was the most reasonable place to put my topic in.My hardware:
linux-bbdu:~ # lspci
00:00.0 Host bridge: Intel Corporation 82G33/G31/P35/P31 Express DRAM Controller (rev 02)
00:01.0 PCI bridge: Intel Corporation 82G33/G31/P35/P31 Express PCI Express Root Port (rev 02)

Just upgraded my FC12 to 13 using preupgrade.On booting up into 13 my panel at the top of the screen that normally holds the menus/system tray etc doesn't seem to have initialised. It's just not there.I had a message about "no system tray detected on this system" which I assume is from one of the applications trying to start up in the systray.I've not found anything obvious in the logs, but then I may not be looking in the right places.

I need to force a shutdown. It seems I have lost an array and now the system refuses to shutdown.
Code:
echo o > /proc/sysrq-trigger
gives the warning but no dice.
reboot -f = nothing.

As I type this, I'm waiting (and waiting) (and waiting) for the Repair Tool Box, "Search For Lost Partitions" tool to stop running off of the install CD. I didn't actually mean to do that (I meant to select "repair file system!) and I don't see any way to abort it! How to I make it stop? (You can insert your best Deanna Troi voice there, if you like: "make it STOP!") Or do I just wait until sometime next week for this rascal to finish examining a THREE HUNDRED GIG partition, byte by byte . .. ?

I ran up2date yesterday and it installed a few new MySQL packages as well as a new kernel.
It got through everything up until it went to install the smp version of the kernel, and up2date spit an error at me and quit.
The problem was that my system keeps old kernels and /boot was full, so it couldn't add the new files there. No problem--I manually removed (via rpm -e) six or seven of the old kernel packages (there might have been a dozen or so), ran up2date again, and it successfully installed the new kernel. Great. So I rebooted the system.
And when it came back up... MySQL didn't start.
I tried to manually start it just to see, and was greeted with "chown: 'mysql:mysql': invalid user" Yikes! Sure enough, a look at /etc/passwd showed NO user "mysql." I quickly tried "useradd mysql" but it wouldn't go for that because there was a GROUP mysql.
I checked to make sure that there was no user with an id matching the group id of mysql and then manually added mysql back to /etc/passwd and /etc/shadow.
After doing that I was able to start the MySQL daemon and it now properly starts up and runs fine after rebooting.
So basically, it's fixed, but I still don't exactly understand what the heck happened. Updating to a new MySQL rpm and having up2date fail while installing a new kernel somehow deletes my "mysql" user from the system? I shouldn't have to be manually modifying /etc/passwd and /etc/shadow because of an up2date error, I wouldn't think.
Edit-- This is a RHEL 4 system now running 2.6.9-89.0.20.ELsmp on a Dell PowerEdge 1750..

My problem is the following : I have a certain Internet connection for a certain network. So many people are sharing this network. What i need is a software on Linux (preferably Ubuntu) that will enable me to monitor the bandwidth usage PER IP Like : ip x.x.x.x using 20Kb upload 200Kb download , connected to this site for example.. The main goal is to know from which IP is the high Upload traffic or download traffic is coming , because i have a certain quota and I'm always getting over the quota (in upload and download) and end up paying extra for the ISP , so i would need to know who is using lots of upload/download bandwidth .

When connected to a Wireless network, how can I use the maximum bandwidth in the network as I am finding that my network speed is degrading day by day as more users are logging onto the network. Btw, I am using Natty Narhwal.

I'm looking for an effective way to manage use of internet bandwidth by users on a local area network. Currently there is a simple broadband router and unmanaged switch, and a standalone Ubuntu Server (8.04) that provides DHCP, DNS and mail for the LAN, and a web server. Ports are forwarded from a static external IP address to HTTP, HTTPS, SMTP, SSH and IMAPS, and some security is provided by IP Tables (managed by using UFW).
There are 5 users on the network, and currently one or two of those 5 are using beyond our monthly download allowance of 30Gb. 1) To be aware of how many users are currently using the internet connection, and to divide the bandwidth between that number (so that if there are, say, 3 active connections, the total bandwidth available is divided 3 ways, rather than one of those users being able to hog all of it).
2) To allow each user to download up to 1/5 of 30Gb each month without any additional throttling (apart from the above), but once they go over that allowance to throttle them individually to, say, 10Kbps until the start of the new month.
I've heard other threads talking about both IP Tables and a proxy server such as Squid. I have no idea which of these would be most suited to the task. Currently, as I said, the Ubuntu server is standalone and only using 1 NIC, but it has 2 NICs and I could be configured to act as a gateway for the LAN, instead of the router, which is set to be the current default gateway.

You may have seen some other posts by me about my final year college project. Im implementing a web based network management website. Iv got a lot of the functionality working at this stage but one part is allocating bandwidth.
Iv got an eircom 3mb broadband connection and I want to be able to split this between users. At the moment I only have my desktop and laptop on the network. Im looking for advice on how i can allocate bandwidth with iptables and/or the tc tool in ubuntu.
My website is on an ubuntu virtual machine and written in php. Whatever about running the iptables and tc commands from php I still need to figure out the actual commands i need to use in the first place.

I switched on bandwidth monitoring on my Ubuntu Server via Webmin on interface eth1. Unfortunately this has filled my disk by writing huge syslog, debug and kernel.log files. How do I switch it off? I can't see a way of doing it in Webmin.

I am running Ubuntu server 9.10 and I am trying to find a way to cumulate and visualized bandwidth for all the ips on my network.
I created a server connected to a mirror port of my router and I am running snort and nessus and ntop to monitor and scan my network for security. Everything is running fine and I can see all the traffic happening, ntop creates really nice report of what is going on in the network, snort with base alert me of probable security problem and nessus help me secure the network with weekly scans.
What else do I need ? I really simply need a software that will calculate the total bandwith usage per ip address. Ntop seems to gather all that information somewhere, but there is not simple way to get the information out of it. I was thinking maybe cacti would be the software to use but I am not too familiar with Cacti and it's interface seems a bit daunting still.
I don't need it to be web interface - but it would be nice. I could probably rig up something on a console base program. What I want the output to be should look like tcptrack but with the running totals for last day, last month, last year, and if there could be a graph for it- even better.

I live in the boonies, so I have satellite internet. It's not too bad, but I'm restricted to 200 mb's of download per day.
I'm looking for an app that will keep track of my usage, so I don't go over 200. I was using "System Monitor", but it's a little buggy, so I'd like to try something else.

Is it possible to share bandwidth over Internet? A friend of me has made a little radio station with win-amp to screw around with. But as you can guess after 10 users the connection flips due to bandwidth limits. So we where wondering if we somehow can share both our bandwidth. I was thinking about perhaps linking some proxy's and combine that with load balancing... Something like that! But i'm not even sure if it's possible to do so.

I want to install Ubuntu on several stand alone machines without repeating the several hundreds MBs updates on each machine using Synaptic. I understand the installations/updates files would reside in var/cache/apt/archives. So I can copy them to be used for the next machine. But specifically how? And can the non-OS files in a 64-bit machine be used in 32-bit machines' updates/program installations?

I am running a fairly standard 32bit 10.10 install, although I deleted Firefox and installed Chrome. I am using Transmission for my torrent downloads. After a lot of reading and trying different things, I have managed to get the port to open. When Transmission is running, even if only uploading and downloading a few k each way, I have great difficulty in getting Chrome to load a web page, it is as if Transmission is hogging all the available bandwidth? Obviously if I shut down Transmission the problem goes away. It also occurred with Firefox before I deleted it.

Since this is my number 1 place for asking questions, I figured I would go here first. So I live in New Zealand where good internet doesn't exist yet, and I'm in a flat with 3 other people and we get 40gb a month which hasn't been lasting more than 2 weeks. It is somewhat of a mystery where all our data has gone, so I need a way to monitor usage. We use a variety of operating systems including linux, xp & windows 7 on my pc, and xbox 360. Is there any kind of integrated solution I can use to monitor everything with password protection so it can't be disabled? I have tried looking in the router, but it doesn't give me many statistics, and I think it combines lan with wan usage. At this stage I don't have the money to make a linux box to put between the router and the switch that can monitor everything, but if it comes to it, I will shell out for one.
