Ubuntu Networking :: WAN Connection When Torrenting
Nov 19, 2010
I have a box setup to do some torrent downloading. I've seen that box achieve over 1MB/s traffic. However, when torrenting at rates above 80-100kB/s my roommates Windows 7 box can't seem to connect to the 'net at all. Sometimes I also have problems with my Ubuntu 10.04 boxes with Firefox timing out. Also, smart net enabled devices such as the Tv and Bluray player that can do Pandora and Netflix can't connect under these traffic conditions.
I realize that the easiest solution is to just pause or BW limit the torrent. However, for some torrents, peak 'net usage time is the only time I connect to any peers. However, my question is why can the network sustain the 1MB/s traffic yet not let multiple people surf the web? Are the Tx packets not getting out? Are the Rx packets not getting in (from the http requests)? Is there a solution *besides* BW limits on the torrent. Is there a router configuration that might alleviate or fix this problem? The service is Att Uverse with a 2Wire 3801HGV router.
On Ubuntu, I know that a user can set a global proxy setting (through a gui, Network Proxy) which will affect all protocols (right?). However, I have set up a server box (no gui) and would like for most of its ports to not go through a proxy. Instead, I'd only like the activity that transmission-daemon does (but not the web UI) to go through a proxy. Is this in any way possible?
Using Ubuntu 10.04 or 10.10, have a router. Whether connected via ethernet or wifi, I'm experiencing a problem downloading files. Trying to download a linuxmint iso , my laptop will freeze up after 5 or 10 min. I have plenty of disk space, and screensaver off. I've googled quite a bit and can't get a clue. My desktop will freeze up too. I can't imagine what would cause this.
For some reason whenever I'm torrenting after a certain amount of time my networking ability just stops. My network traffic shoots down to zero and I can't bring anything like the ability to request a website back until I restart.
After doing updates to get current with Debian Jessie, I've noticed very annoying network problems going on.
This all happened while also setting up a media server box which led me to much confusion, much of what is described here [URL] ....
I've started this new thread to try to diagnose and properly take care of this specific problem alone:
Browsing the internet becomes very slow, unbearably to the point everything keeps loading up forever. This only happen while having a torrent application opened, the effects are almost immediate, closing the application and browsing resumes as normal.
How about throttling back torrent? This does not work, it even doesn't even need be at top speed. With bare minimum connections and speed will still lead browsing to a crawl.
Even so, every other device on the network is un-affected, router and other PCs continue to browse and respond very well, making it a specific on the computer in question (but also happens on my other debian jessie machine).
Can I even reach the internet? Yes I can, and this is the weird part... I can ping, solve DNS and almost everything else without issues, the only thing affected is actually browsing the internet.
I'd even setup DNS cache with dnsmasq to see if it could speed things up. Disabled ipv6, and trying pretty much every method I could find.
Having pretty much ruled out dns problems and internet connectivity, I'm at a loss for what to look for and try. Only symptom I can describe now is that the browser will start to load up webpage but never completes... but only while torrent is active.
My current setup:
I'm on Debian Jessie, a desktop with eth manually connected. Using dnsmasq for dns caching. Disable ipv6 on the network (by the way, it keeps disabling it self I dunno why).
Running KDE with ktorrent as the client. The same thing happens on my setup media box, also Debian but with deluged running instead.
Browser in question are Firefox and Chrome, both have issues with this.
Turns out it was just a setting in my own router, that apparently limits numbers of connections made, meaning while torrent is working other connections were sure dead.
But it also happens when lots of connections are being made in other ways too. The router in question is Humax HG100R-L2, provided by my ISP. The setting is in the firewall section called IP flood detection.
I'm trying to create a PAN (Personal Area Network) using a laptop (Siragon ML-1040) and my desktop computer, but I get the Connection Refused (111) error.
Blueman doesn't detect any network service between the two computers unless I start PAND on one of them and then it detects the NAP service. That, only after I enable the NAP/Workgroup services on the Services submenu in Blueman. However, it doesn't work neither with the NM plugins or without them (dhclient and that other one I can't remember the name of).
Any clues over here? I'm using pand 4.91 and blueman.
Its a case of ".... wireless network connection active but still not internet connection .."I am using WEP - 128 key ... Works when I connect directly using ethernet cable ... but not wireless (pci and wireless router)
I'm trying to do a SSH connection between my home and work PC both machines are running ubuntu 10.04. I have read all the comunity documentation at [URL] from Work PC. I went on to the web site what is my ip address and noted down the number, From Home i opened a terminal and typed: pnig (ip address). to which their was no reply, now i'm assuming i need to configure the works router to except connection requests, is this Correct?
Also what information do i need from my works network and how do i get it? I understand that I need the routers expernal ip address, but how do i referiance a specified computer after that address? What program do i use in ubunu and how is that information applied to it?
When I have video running and the video stops, I see that the connection is destroyed in about 5 seconds, which is what I want. If, rather than stopping the video, I pull the plug, I have seen it take 350 and 380 seconds before the connection is destroyed. Why is there such a large difference in the time to destroy a video connection between stopping the video and pulling the plug on it when using net filter connection tracking? How can I shorten the time for the connection to get destroyed when pulling the plug?
I have two linux laptops. Currently, I'm using both of them at work, side-by-side. Now the problem is, I'm connected to a wireless router, but the wireless only works on one of the laptops. So I'm stuck with one laptop that has no access to the internet. Both machines do, however, have working ethernet nic cards. So, I was wondering if I could use the laptop with the wireless connection to share the internet connection with my other linux machine and access the internet on both of them. Or as an alternative, just use the internet on the machine without wireless and be able to switch back and forth, that would increase my productivity like 30 fold.
I'm trying to setup PPPoE connection to establish my DSL connection, but I got
Code: pppoe[3885]: read (asyncReadFromPPP): Session 4479: Input/output error pppd[4104]: Cannot determine ethernet address for proxy ARP in my sylog file.
When I do pppoe-start, it connected but I cannot ping into any destination (even to my modem in the same network). DNS servers are explicitly set in pppoe.conf and resolv.conf. Did I miss anything?
I have problem in making connection to my vpn server I can make connection from windows xp to that but can not open any website and I can not ping 172.16.10.1 when connection established.
These are my configuration files:

And vpn connection is lost after establishing a lot.
I have just installed ubuntu 10 on a thinkpad t410. At first everything worked swimmingly, INCLUDING the wireless. After about five minutes, the wireless stopped working, in that it seemed to think it was still connected but pinging didn't work. I've now restarted several times, and each time I restart, the wireless works for about 1 minute, then stops working. If I try to disconnect and reconnect it will not reconnect (until I restart, that is).
iwconfig shows the correct ESSID and ifconfig shows an address, and "connection information" shows a varying percentage of connection.
I connect to my work with GRDC through a VPN. All worked fine until yesterday. IT is now very slow. Could this have anything to do with the fact that Update Manager was only able to do a partial upgrade?
I use Ubuntu 9.10 I tried the RDC on a Win XP machine and the speed is normal, so I don't think the Remote Desktop Server is the problem. Is there a way to test thespeed of the VPN connection or the RDC connection?
I have 2 computer: 1 computer install ubuntu v9.10, in this computer already installed openssh-server and openssh-client, and 1 computer install windows. In computer with windows , i used putty connect to computer with ubuntu, but i can't connect. I don't understand what's error. In the Putty , i configured: IP : IP address of computer Ubuntu. Port 22 Connection Type SSH
This is error: "Network Error: Software caused connection abort"
In computer with windows, i can ping computer with ubuntu and in computer with ubuntu i can ping computer with windows.
I have the "Work Offline" problem: when I boot up, the icon on the toolbar tells me I have "No network connection". This is not quite true, since I can access the first page of any website - only subsequent pages are inaccessible. I get a message saying that Firefox is offline. However, when I uncheck "Work Offline" in the File menu, it makes no difference to this behavior.
The problem is on my Ubuntu Dell desktop, which is connected to the internet with cable broadband via a D-Link router (wired connection). It has worked fine up till now. I use Ubuntu 10.04 and Firefox 3.6.11. I am writing this on my Ubuntu Dell laptop which is wired to the same router, so I assume the problem is not the router. I have tried various strategies suggested in threads on these forums, including editing about:config, changing "allow" to "deny" in some lines of /etc/dbus-1/system.d/NetworkManager.conf and changing from Automatic (DHCP) to Automatic (DHCP) Addresses only, but no luck so far. The contents of ifconfig are:
If I comment out "auto eth0" as well, it makes no difference. If I uncomment both lines ("auto eth0" and "iface eth0 inet dhcp") then I lose the internet connection altogether.
I am running Ubuntu 10.10, and I would like to use my computer to share the internet connection from an ethernet port. For example, I would like to set up my computer as a wireless access point so I can create a network that other computers can connect to for internet.
i m using RHEL5 on my server machine and open suse 10 on my client machine.both system ping each other, firewall is off of my server machine,i put a file from my client to my server machine using scp command but ftp command is not working when i want to open connection i receive a message "connection refused".what can be the issue?
I need to setup an Ubuntu Server to handle backups over the network (probably rsync over ssh). That server will then transfer the backup data offsite over a secondary external data line.How can I configure the ethernet interfaces to handle such a scenario?
I just installed Ubuntu 11.04 desktop on my desktop in dual boot with Windows 7.
Heres my problem, I am unable to connect to the Internet even though my wired Ethernet connection says it is connected normally. The wierd thing about this is that I also have a wireless card in my desktop and when I connect through that I am able to connect to the Internet. I am connecting to a router that is functioning as a repeater to my main router/cable modem. I have tried to solve this myself but am having no luck. Ironically, earlier today suddenly my ethernet connection worked for a few minutes without me modifying anything.
The output of some terminal commands are below.

However a pint to that ip address (my router) is successful.

Hosts.allow and hosts.deny are both fine (not blank but no entries)
my netbook shares it's wireless connection to my desktop. i've done this through the gui (edit connections > eth0 > ipv4 settings > shared to others) and it has worked for the last i don't know how many months.recently it had become a bit touchy with regards to how it was set up. it didn't work unless the netbook was already booted and wired in at the time of booting the desktop.now however it's gotten even worse and all i get when i connect them together is
I just want to use Internet Connection Sharing (ICS) to connect to the internet. I have done a massive amount of troubleshooting, but some of it seems to contradict itself, and the only two things that I know for sure are that it used to work, and that my Ethernet cable is not the problem. When I use Terminal utilities like ifup and dhclient it seems that it can not determine IP information, but when I try to put it in manually, the "Apply" button grays out right after I finish typing it in. When I try to connect normally, in KDE or GNOME, the icon acts like it's connecting, then instead of having the connected icon, I receive a notification that "the network has been disconnected", and it goes back to the disconnected icon.
Oh, and by the way, I know that I could probably find a workaround, but I have limited resources, and this used to work. The Linux is a Dell desktop with Fedora 12 and the Windows is a Windows 7 HP laptop.EDIT: I hope that I didn't mess something up, but I accidentally used system-network-config to try putting in the IP address there, and ended up changing it back to the original settings, but the computer is now calling it Auto Ethernet in the taskbar icon, although sudo iwconfig in the terminal still calls it eth0.
I have installed fedora 12 recently. after installation i tried to connect to the internet using BSNL broadband connection. I filled in the details such as IP, Netmask, Gateway and even DNS servers. In the services also I ensured that the network manager services is on. However even though my computer cannot connect to the internet. I then tried the ping test of the modem from the address 192.168.1.1 and found that the ping test is successful. Then i tried the network administrator and there I noticed something unusual.
There are two options in the devices eth0 and eth1 thats ok but the unusual; thing is that the Activate (green button), Deactivate (red button) and even the delete buttons are in the background and I cannot select them. Isthis the problem for the network connectivity.

I'm writing from italy and I need your help. I installed Ubuntu 10.4 3 days ago and when I open the firefox page this can't be loaded, even if I war connected whit the ethernet cable. So I follow all the sequence of information after i digit "pppoeconf" in the terminal. At the end the system says that the connection was establieshed, so I restart the computer and when he was loaded again... well...the network manager in the upper-panel near the volume control was disappeared! i create a new wired connection giving him a manual ip, subnet mask and gateway. I tick the option connect automatically, but the computer remain unconnected.
Is it possible to configure ubuntu in a way to connect to a specified VPN connection on startup? The system should only use this one VPN and never any other connection.
I'm running Ubuntu Karmic on my desktop machine which is connected to my wireless router (via LAN cable).
I have two laptops on the LAN as well. One is my wife's Windows 7 laptop and the other is my Ubuntu Karmic laptop.
They both connect wirelessly to the LAN and all three computers have static IP addresses assigned.
So here's the issue. The desktop serves the laptops over the LAN with Samba file sharing, SSH, VNC and DAAP.
From the Windows 7 laptop, the connection over the LAN is fine. I generally use it to connect to the Samba shares and occasionally use it for VNCing to my Desktop's....desktop. It is fast and responsive.
From the Ubuntu laptop though, everything seems very slow. Connecting to the samba shares results in a wait of at least 30-60 seconds, even if they have only recently been accessed. Once it has connected (i.e. once the share opens up and you can see files) actually opening the files themselves is delayed too, but not to the same extent.
Also, connecting to the desktop via VNC is intolerably slow, with mouse movements being so delayed that it is almost impossible to click on anything.
SSH takes a long time to connect too (up to 30 secs) but obviously once connected it is fine. In a similar vain, FreeNX connection takes a long time to connect but once the desktop has loaded it is fine too.
I can use FreeNX instead of VNC but actually like using both for different functions. I understand VNC is slower than FreeNX but over a 100Mbps LAN connection I wouldn't expect it to be slow at all.
This laptop used to be a Windows Vista/Win7 laptop prior to being replaced with Ubuntu and it was able to connect to the server with no speed problems.
