Fedora Networking :: Bittorrent Impact On Network Makes No Sense?
May 26, 2011
I noticed my Internet slows to a crawl when I'm running bittorrent, but when I look at my torrent app (Transmission), the upload/download speeds are mere kilobytes per second, and my Internet has much higher bandwidth capabilities than that.So I tested it:No torrent running
I have an internal network behind a server <10.0.0.1> connected to the internet that NATs my ip <10.17.11.88> only. NAT is not allowed to any other ip addresses. When I use Transmission Bittorrent client to download torrents, The thing is that this 10.20.0.244 is not my machine and doesn't have access to the internet at all. What is happening here? Can anyone help me?
using fedora 9 i've problems getting bittorent to work. i have an external kerio firewall but my messages seem not to get thrue. I read about port forwarding, as a way to speed up bittorent I interprete that as bundling the port series 6881 till 6999 to ferdora:6881 so all the ports are channeld to the bittorent machine and 1 port.(tcp and Udp)
that how I did set it up, but i seem not to get a lot of throughput i guess Maybe 1kb per week, I do not know if this is what is seen as a slow bittorent.... on the firewall i see a lot of messages running arround but nothing seems to advance
what can I do, verify to get this running. (I temporarly switched off fedora's firewall( internal) is there a way to structuraly test bittorent? is my forwarding rule correct? (input multiple ports to single port?
After I installed a gigabit router, I could not access my nfs server anymore; I tried with the previous physical set-up and all was OK so clearly it is the new router that is the disturbing factor. After some (and then some) experimenting, it would appear that the following specific feature needs to be enabled: Filter Internet NAT Redirection This feature uses port forwarding to block access to local servers from local networked computers. Select this feature to filter Internet NAT redirection. It is not selected by default.
The reason I had simply looked over it is that I did not see how internet nat redirection could be related to the local network. As I read the details, it became clear that it really is but it also raised new questions. Have I now allowed just anyone on the internet to access to my nfs server? Because the description is not very clear either as it mentions both internet and local network. And what is that odd terminology? Filtering allows access, not filtering does not - that seems like the world upside down ...
I know, that this thread is old one, but I am having the same issue. It does not seem to me to be the problem of single torrent. It is more the way how much do I use my connection. If I have only 1-2 torrents, everything is ok. If I have 10, I get this problem. It is also followed by aprox. 30 secs of no internet connection. I use Deluge for downloading and my limits are set like this:
max connections: 200 max upload: 300 KiB/s max upload slots: 5 max connection attempts per sec: 20
first of all I am sorry about the mess in the question, I hope I am being clear enough.
I am using VectorLinux 6.0 standard, kernel 2.6.27.12. iptables v1.4.0 Deluge v1.18 the problem is that as soon as I do Code: iptables -A INPUT -j DROP Deluge hangs and stops responding.
I am trying to make iptables to drop everything except tcp,udp 6887 (for torrent) and except established and related. iptables -L looks like so:
[Code]...
Edit: Now I see that Firefox also hangs if I try to right click a tab when I have iptables -A INPUT -j DROP.
I have noticed that a common issue to several distros is the fact that the networking subsystem doesn't automatically detect the link if an ethernet connection is disconnected and then re-connected to the NIC after boot. If the ethernet cable is connected after the system is up and running, nothing happens - ethtool eth0 shows link detected: no, and you have to restart the network service to let the NIC know that there is in fact a link, and actually connect. I have a Fedora14 (KDE) box with a brand new Asus motherboard with embedded NIC. Everything works great except the auto-detect of a freshly connected ethernet connection if the link is down to begin with.
Am I missing a ethernet link sentinel utility or something, or is this just the way linux works? I have done plenty of research on plenty of posts, and it seems this is a common problem, with no solution other than manually or programatically restarting the network service in a script to detect the link after a disconnect.
I don't know what's wrong with my Ubuntu but everytime I open Transmission BitTorrent Client, the internet connection become unstable from time to time. Internet access run smooth without it but I need it to download file from torrent...
I used Dual-boot with XP and Ubuntu and I got no problem with 9.10 Karmic Koala but just got this problem after upgrading to 10.04 Lucid Lynx.
I tried Ubuntu, Kubuntu and now Xubuntu, all 11.04. I've also tried Deluge, Transmission and Ktorrent. With 10.10 everything worked fine (all variants). Also, in Windows 7 it's working fine. But now it drives me crazy. As soon as I start a torrent, the download starts but after 30 seconds or so the download drops to a zero. Also, I'm not able to browse anymore. The networkmanager tells me I still have a connection.
Some say it has something to do with the number of peers the client connects to, or it's my router. My router isn't the problem, as it's working fine with 10.10 and windows. So maybe it's the number of peers right? Question. Why can I connect with over 200 peers at the same time while I'm using 10.10 or windows, but can't do it with 11.04? Better put, what should I do to get this working fine again? Going back to 10.10?
I was just wondering if using a non-smp kernel would be ok on a older p4 system with no x. I am wondering due to some functionality in IPTABLES that is broken in the SMP kernels ( -m owner --sid.pid,cmd-owner).
Could someone that is running a NON-SMP kernel advise as to whether the support for -m owner --cmd-owner is working in iptables with those kernels? Also, could someone advise me if running a NON-SMP kernel is even advisable? The machine will not have x.
I have a server provided dns and sendmail service, dns keeping record for my public servers. I don't want my server to be open dns server, so I just add recursion and forwarders option to named.conf, like: allow-recursion {192.168.x.x/24; 123.123.x.x/28; 127.0.0.0/8;}; forwarders {publicDNSipA; publicDNSipB;}; After restart named, all sendmail user can't mail to other internet account (like xxxxx@gmail.com); but local account is ok
Using Ubuntu 10.10 I have a VPN account with VPNtunnel.se. I configured everything as described on their site. It uses OpenVPN It connects no problem. However; after it connects instead of having a nice secure connection I have no connection at all! I can't access any site, email, bittorrent all come to a screeching hault. The service works fine in Windows. I'm useless with linux networking.
I have just set up the transmission bittorrent client on my server (using the web interface), and am trying to get the port forwarding right. After noticing low download speeds (and rare uploading), I decided to check if a port needed to be forwarded.
I found many conflicting sites, mentioning both the ranges 6881-6999 and the port 51413 (as well as TCP and UDP versus just TCP). My current configuration is to forward TCP and UDP port 51413 to my server.
my question is according to google search I need to umount the filesystem point in order to reduce its size.... so it means I will require that nobody uses the system? since /var logs a lot information?
I also have the option to reduce /root but I think is more complicated.
so what are the precautions in order to reduce /var/?
My server has been the repeated victim of bandwidth attacks: any large file on the server is downloaded repeatedly, with the goal of pushing the server over the provider's bandwidth limit. How can I lessen the effect of these kinds of attacks with IPTables or APF? For example, can I set the server to: Is this possible? Is there a more effective way, and can a firewall even do this? My web server is Lighttpd, perhaps I can place such a rule directly in its config?

I think I should be getting more speed then I am.I would like to install Ubuntu Server.What version is the most stable, and will provide the best speed?I have to download my server files from the internet. Is this possible without the GUI?Is there anyway to control my server remotely, without any impact on performance, VNC is a huge impact.I want to run a mail server as well, is this possible with out a performance hit?
I have installed qemu/kvm and created a Bridged network connection which works just fine(Windows 7 VM won't work in NAT mode.)
But when I try to use NetworkManager it says that I have no network connection because the network isn't managed, (I set the settings in ifcfg-br0 and ifcfg-eth0 to be managed)
The real problem is that now I can't use my VPN connections (I have many) in NetworkManager.
Is there a way to have both of these pieces of functionality?
I've been using Kubuntu 9.10 for several months now. For most of that time, I configured and used with no problem several network printers.. a HP LaserJet 3015 at home connected to a Windows machine, and a Xerox Phaser 8560 at my coworking space connected directly to a router.
However, several weeks ago I was at the coworking space, requested a print from my web browser, and in the printer selection dialog, observed the list of printers expanding... some sort of autodetection of network printers was occuring, and multiple instances of the same printer were being offered, with slightly different names. Printing to these devices did not work.
Now, after a reboot, there are NO network printers available no matter what network I'm connected to. When I use the Kubuntu printer configuration tool and try to set up a new printer, it asks me to "Select a connection" to which the only option it gives me is "Other". When I put in an address for the printer it just cycles endlessly, never finding anything.
i am working on a client server real-time gui application written in C++ for Redhat. There is an issue with this application that it makes the system hang. i am not able to sort out the issue as it happens randomly. Sometimes with in half an hour it makes the system hang, sometimes it takes 4 or 5 hours when it receives realtime data. Is there any way to debug this issue. I tried valgrind..but it was not of much use..
I am using Ubuntu Incredible Ibex on a Lenovo T400 with a Hawking HWUG1 USB adapter. I was successfully capturing WPA handshakes good enough for Aircrack-ng. However they didnt satisfy Cowpatty.
The built-in wireless adapter on my Lenovo T400 appeared as wlan0. The HWUG1 USB adapter appeared as wlan1. The airmon-ng start wlan1 command configured the HWUG USB adapter as mon0. Things were okay but not great. I wanted to use Cowpatty and the Rainbow tables but my captures werent satisfactory, except for the ones on my own router five feet away. I even tried using a 3 foot omni 12 dB antenna
I started to suspect my drivers.I was using the drivers that came with Ubuntu Incredible Ibex. I saw the website [URl].. and followed the instructions carefully to install the rt73-k2wrlz-3.0.3 driver. When I ran Airmon-ng start wlan1, I saw that the Hawking was indeed now rausb0 and using the rt73 driver.
When I ran Aireplay on my WIFI router to de authenticate myself I got 0/0 acks. Previously I was getting something like (63/66 acks).It also happened on other test routers. So I did some more reading and I was thinking the rt73-k2wrlz-3.0.3.driver was incompatible with the Incredible Ibex kernel and Ubuntu. I found the site [URL].. and followed the instructions to install the rt73-cvs-daily driver. However I didnt install WICD.
After that, my HWUG1 USB disappeared completely as well as wlan1. It doesnt show up when I run the ifconfig command. However my built-in onboard wireless adapter shows up as wlan0. How can I bring back the wlan1 and my Hawking HWUG1 USB adapter? Furthermore how can I reinstate the original driver that I was using?
I often connects my laptop (Asus EEE) to my HTC desire hd with the wifi hotspot. But this doesn't work since yesterday when I upgraded to 11.04. When I connect the laptop to the phone the screen on the laptop goes black with a lot of scrolling text then it freezes.
This worked out of the box without any problems with 10.10.
I'm trying to control the access in my server. I did an application that can read audit logs and sys logs with the purpose to send me a report by email with important information about the user. It's a SH file. My problem is start the program when someone makes a ssh connection.
I've done some research on the issue of blocking bittorrent traffic. What I've come up with is that it is very difficult to detect the data traffic. Tools such us ipp2p fall short because of encryption of the data between peers. What I'm thinking of (and starting to test at the same time) is to block the "single poit of failure" - the trackers. My idea is to collect a list of IP addresses of the most used trackers and block all traffic to them:
Code: # bittorrent trackers # # tracker.prq.to $IPTABLES -A INPUT -d 85.17.80.0/24 -j DROP # # tracker.openbittorrent.com $IPTABLES -A INPUT -d 188.126.64.0/24 -j DROP # # free.btr.kz $IPTABLES -A INPUT -d 195.210.47.0/24 -j DROP # # tracker.mightynova.com [Code]....
What do you think about this? Is this going to work? Where could I get a bigger list of bittorrent tracker addresses?
I have a separate data partition on my F12 box with one dir for my children and subdirs for each of them. because they had no rw- rights and because they sometimes use one of the other logins to work for school I changed the permissions for their dir so that anyone has access. I used
Code:
# chmod -R 666 [their directory]
after that Nautilus displayed an empty folder even with 'show hidden files' on.however, with
Code:
ls -lh
on the dir and subdirs all the files seem to be present (luckily).
Does it make sense to run sshd confined/protected by apparmor? I get tons of attack/hack attempts on my ssh port daily, I created a white list on my firewall to specify the IP addresses that can ssh into my network. I was also thinking of activating the sshd profile in apparmor for some added protection?
Wallpaper, with a complimentary color scheme for windows decoration, and icons and sound effects inspired thereby, loaded as a set. Is there an app that does this for KDE? It seems like linux gives me more options, but without an important tool to utilize them. I'm sorry to bring a question here that's probably been asked many times over the last dece, but the likely hits on "theme" and "windows" has overwhelmed my search fu.
