Ubuntu :: Possible To Speed Limit Specific System Not Entire Network?
May 9, 2011
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 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 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 just recently reinstalled (clean) Ubuntu 9.10 Karmic Koala last week. In that time, over 40GB of log files were created until the FileSystem was full. I then received a low disk space message and ran disk usage analyzer to find out that almost all of the 44GB I had free were taken up by the /var/log directory. I then preceded to delete the 5 largest files which freed up over 40 GB of space.
Basically I believe that I have two problems:
1.) The log files are logging too much information (40 GB in one week).
2.) I need a way to automatically limit the size of the log files. I have tried searching online for this solution and briefly came across logrotate but I don't believe that this will completely solve my problem as it only compresses and backs up older logs. I need something that will remove old log entries altogether. If logrotate is capable of this can someone please walk me through the process? I do not remember all five log files that were in question but they did include: messages, syslog, and daemon.log. I believe kern.log may have been involved too.

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.

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.

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 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.

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?

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'd like to limit login attempts for specific user. I've found information in manpages: [URL]but I'm not sure if this '@' is purposly there, so would be that correct?
Code:
aparaho - maxlogins 4
or
Code:
@aparaho - maxlogins 4
Maybe '@' is a group syntax? I'm confused.
What happens after 4 failed loggins? Is it enough to restart system to get another login attempts?
Are there any other values that it is reasonable to limit for safety reasons?

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've written a program for a class that my professor will be testing in various low memory environments to see how it behaves when the program runs out of memory. Is there a way I can simulate the execution in a low memory environment without creating a virtual machine?

I'm trying to limit access to port 8443 on our server to 2 specific IP addresses. For some reason, access is still being allowed even though I drop all packets that aren't from the named IP addresses. The default policy is ACCEPT on the INPUT chain and this is how we want to keep it for various reasons I wont get into here. Here's the output from iptables -vnL
[Code]...
Note the actual IP we are using is masked here with 123.123.123.123. Until I can get everything working properly, we're only allowing access from 1 IP instead of 2. We can add the other one once it all works right. I haven't worked with iptables very much. So I'm quite confused about why packets matching the DROP criteria are still being allowed.

I setup the hostname for my linux machine to Linux. If I try ping Linux from the same computer it works. If I try from another computer inside my network the host can not be resolved. If I ping the IP from another computer it works.
I take a look in my router at DHCP client list and my linux machine doesn't have the Hostname set up.
How to broadcast the hostname to the entire network?

Custdistro means it will backup your all/thing without/home and customback means it will backup all thing in /. It can create an ISO if your backup is less then 4 GB. Well, i've made a lot of changes to ubuntu 10.04 and now i love it! It does everything i'll want from any computer. This took me a lot of time, follow several tutorials and destroy the entire system a couple of times. The last one is a BIG problem because restoring my system to the state before i ****** all up takes some time again.Do any of you guys know how to backup all my system settings, programs and files? So that if i corrupt my system again i can restore it to be exactly as my current state?

I've got an odd problem and was wondering if anyone had any insight. I'm on Ubuntu 9.10 on a Gateway E-100M and everything works great except for firefox. My machine will hard freeze about once a day when using firefox. The whole OS -- no mouse movement, no keyboard response, etc.I've switched to Chrome for weeks and I get no issues at all. I switched back to firefox and it hard froze within the first hour or so. I know it's unusual that an individual program would freeze the whole OS rather than just crash, but it seems to be a fairly consistent pattern.

When I click certain links, such as the one below, Firefox consistently crashes.
The bigger problem is that when it does, everything grinds to a halt, and I have to press the machine's power button.
Is there a way to kill processes when the system locks up? This is on Ubuntu 10.04 Lucid Lynx, using GNOME.

I administrate a network with approximately 140 PCs. They all have Ubuntu and I want to be able to turn them on and shut them off remotely from one of the servers. So can you tell me what is the best way to do this ? A shell script would be a nice option if its possible.

I've been a loyal Ubuntu owner for 3 years now, and I've been wondering if there is a place where I can get the entire break down of how the OS works. I don't know programing but I would like to learn about what ever language Ubuntu uses to work.

I supposed to install a server (mail,dns,dhcp etc) but we need to record all the steps that we're doing, thats why i decided to setup a virtual machine and record everything with Xvidcap (which works great by the way).
The problem:
Now we need to test this server at school which means i have to take my computer to school and setup up a network overthere, whats the big deal about this? my computer case is a huge xclio a380 which weights about 35lbs (not kidding) so taking this thing to school riding a bus 3 hours to get there every weekend is not a good idea.
Is it possible to make a copy of the entire system and put it on a laptop?

Is there any function I can use to set the timezone of the entire system in linux using C? (Other than creating a symbolic link between /etc/localtime and /usr/share/zoneinfo/). Could I specify the timezone offset in seconds by any chance?
