Networking :: Throttle Client Connection Speed From NAT Server
Sep 5, 2010
I have about 5 computers on my network that get their internet connection from a Linux NAT server.
192.168.12.02 is a Linux server that has a NAT set up to share the internet connection.
192.168.12.03 is a download server that is almost always downloading
192.168.12.05 - 192.168.12.20 is assigned by DHCP to users.
I want to make it so that the download server runs at full speed but is throttled only when someone from the user IP addresses range tries to use the NAT server.I think I'm looking for some way to set the download server's packets to have a lower priority than the client's packets. Is there a way to set this in the Linux server?
I would like to know if it is possible (and, if so, how I would go about doing so) to temporarily limit my Internet connection on a Linux box.
I am developing some new features for one of my Web sites, and I want to see how it performs when using a slower Internet connection. Although it's great for most aspects of my job to have a lightning-fast connection (around 25000-30000 kbps download and 20000-25000 kbps upload speeds), it really makes it difficult to know even what average users might experience when using some of the aspects of our Web site.
I have Linux Mint installed in VirtualBox on my computer, and I'd like to find some way to potentially temporarily "trick" that installation into using a much slower connection to the Internet for testing purposes.
I am facing connection refused error 111 in TCP client server program, in android native code which in C , but if code is in JAVA it works fine, but i want to continue in C only, in manifest file i have given permission and ip, port is correct .What am doing wrong?? or is their any network setting?? am using UBUNTU 10.04and If both client server Linux pc it works fine. only if android emulator becomes client then am getting connection refused
So I setup VNC on my Mac (that runs Snow Leopard) and my PC (that runs Ubuntu) and I gave the IP address to Ubuntu, entered the password and it worked fine. The problem is that it still works fine... I only made this connection to test it because I thought it'd be cool, which it was (for a while). Now I cannot delete this connection whatsoever!
I have tried changing the password on the Mac, limiting the users, and even switching it off completely by unchecking its checkbox. I have also tried limiting the users... BUT UBUNTU STILL MANAGES TO GET INTO MY COMPUTER! This is really annoying because anyone using the PC downstairs can now go into my Mac and mess about with things - I hate this. Somehow, Ubuntu has locked in on my Mac and, despite the changes, can earn access no matter what!
This is a recent problem, and I can't pinpoint any change/upgrade that would cause this. Rsync transfer from Client to Server: sent 11756196 bytes received 1032741 bytes 138258.78 bytes/sec total size is 144333466390 speedup is 11285.81 Pinging back and forth from each machine is fine. No Ifconfig errors Client, but Server has RX packet errors.
I have a "friend" who hosts a couple of websites that I maintain. I have always used filezilla client to connect and update the files on the website.I lost access for a little while and he said that "The profiles had accidentally been dropped".He reinstated everything but now I cannot complete a log on session. I maintain several other websites which have the same PURE FTPd server at their end and I can connect to these OK.The delicacy of the matter is that, with no changes at my end, and my other sites working, logic suggests that something has changed at his end. I have very patiently worked through all his suggestions but to no avail.I can't suggest that he is at fault when he claims expertise in the field and I am a complete lamer when it comes to FTP.
I wonder if anyone would be kind enough to review the log on result below and see if they can throw some light on the situation for me.(I have anonymised the IP address and other information for security reasons)
I have installed libapache2-mod-bw and it works great to throttle download speeds to the clients (i.e. - the bandwidth out of the server can be controlled just peachy).However, I need to limit the bandwidth *into* the server from specific networks because my WAN links are tiny and do not have QoS or shaping of any sort (I know, I know - contracts in place - will be fixed in November - not my design).I know that there are ways to throttle this at the interface level (e.g. - wondershaper) but I'd like to allow full bandwidth to the clients that are connected locally. The server in question is for web file transfers (under apache2 on 443) and expected file sizes are up to 2GB so a per-network limit would prove helpful.
Me and my friend are using the same internet, sometimes he downloads something or watches a movie online. When he does that my internet connection becomes very weak. So is there any way to put limit on his computer? Like only 30kb/s
I'm getting these strange answers from opera when I ask it what speed for download does it have. I am downloading fedora using ubuntu right now. Why opera tells me it's downloading with almost 200kb/s while the system monitor from ubuntu can't pass more than 110kb/s ...
I recently setup my two PC's for network file sharing using Samba. I notice the max speed I can transfer a file is 89kb/s instead of 100Mb/s. How can I increase the speed to max 100Mb/s? Both systems are running Ubuntu 9.10 w/Samba.
I am trying to Setup citrix ICA client 9 on Ubuntu 9.04 Server. I installed it very easily and I am not getting any lib error also. But when I try to connect to the citrix server, it fails with a pop up saying "Error in Network Connection Network or Dialup connection may be preventing ......" This is driving me crazy from 3 days. My project is to check the feasiblity of a Linux desktop
I have installed Ubuntu 10.10 on my Dell Latitude D830 laptop using the Wubi installer. Everything seems to be working fine except for my wireless connection. When I plug in my wired connection and test on speedtest.net I get download speeds of 20MB/second. However, when I switch to my wireless connection, I barely break 1MB/second. I have an Intel PRO/Wireless 3945ABG wireless adapter. I have scoured this forum, Google, everywhere I can think of to find a solution and none seem to work for me. I love Ubuntu but this might be a deal breaker...
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?
I use ssh to port forward my browser(firefox) using SOCKS to a "server"(ubuntu desktop with ssh ) I have in the UK, to watch iplayer etc wen traveling... I forward port 1024 (default port for SOCKS? **mite b untrue..). the "server" is running ubuntu 11.04.
could i set up a transparent proxy(squid) on the "server" in the hope tht it speeds up the connection etc... my thot was get squid to listen on port 1024, or set up the ssh port forwarding to the squid port... would tht work? is the a better/different way to do it? the issue is tht sometimes the ssh connection can b slow at times
I actually have a server and a client.The client must connect to the server (via internet) to access to external websites. (You can see the attachment, maybe it's more clear )My actual problem is, I have configure Squid on my server, but I want to force SSL for the connection between the client and the server.I didn't really find nice tutorials about on that, maybe someone have an idea ? Or maybe some indications ?
Is there a way by which i can improve my Internet speed. I have a 100Mbps connection but the download speed is only 100kbps. I know that my ISP has limited by connection speed, but i am curious to try as to how i can get the maximum speed.
I have a pretty decent DSL connection that usually gave me about 105KB/second download speed over wifi. The "official" download speed was 1.5 megabits so I should have been getting a bit more, but that's not my question.
I recently switched to Mint from Ubuntu. Now my download speed is significantly slower, to the tune of 45 KB/second. Since the connection runs at normal speed when I connect via an ethernet cable, my guess is that mint doesn't give enough power to the wifi card. Is there any way I can fix that?
I am using redhat on server and open suse on client. When I want to ssh from my server machine the following error occur "connection refuse". I execute the following command on clien machine "/etc/init.d/sshd start". It shows the following error just after command execution "sshd re-exec requires execution with an absolute path".
I believe I'm running Kubuntu 10.04, but don't quote me on that. Here's the version string from dmesg. Linux version 2.6.32-31-generic (buildd@crested) (gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5) ) #60-Ubuntu SMP Thu Mar 17 22:15:39 UTC 2011 (Ubuntu 2.6.32-31.60-generic 126.96.36.199+drm33.14 I have an emergent problem with my wired ethernet resetting the connection on a frequent basis. When it resets it re-negotiates the link speed and I often end up with a 10Mb/s link and on some occasions a 100Mb/s. The configured speed for the link is 1000Mb/s full duplex using a preup ethtool command. I do not use NetworkManager but have the interface configured in /etc/network/interfaces.
I wish to connect to MySQL using an ODBC connection and I'm using isql to test.

I have a number of Ubuntu machines running. Our NAS is FreeNAS. I am typing this on an Ubuntu 10.04 desktop that is successfully connects to an NFS share on the FreeNAS box every day. In addition, we have 3 10.04 server machines that also stay connected to the share successfully, Yesterday, I installed a new 10.04 server machine using IP 192.168.0.11. Everything works except connecting to the NFS share. It always returns with: mount.nfs: mount to NFS server '192.168.0.13:/mnt/amrd0s2/public-NFS' failed: timed out, giving up
Here's what I have checked: I can ping 192.168.0.13 (obviously) The NFS export mask is set to 192.168.0.0/16. The other machines are all on the same subnet as this problem machine (192.168.0.*) nfs-common, nfs-client, and portmap are all installed and running correctly. portmap is running correctly showmount -e 192.168.0.13 give the proper response:
Export list for 192.168.0.13: /mnt/amrd0s2/public-NFS/ 192.168.0.0 iptables isn't even installed (these machines are segregated in a private network behind a hardware fire all) There is nothing related to NFS is any of the syslogs. dmesg has one entry: [6.025966] FS-Cache: Netfs 'nfs' registered for caching which is insignificant. how to at least debug the nfs-client short of downloading the source and actually stepping through the code.
I was wondering if there was a way to connect over ssh "backwards". For example, lets say there's a client connected to example.com via ssh from behind a router. Well you wouldn't be able to ssh to that client unless the proper ports were forwarded on the router right? So I'm wondering if there would be a way to connect to example.com through ssh then from there connect to the client using the already existing ssh connection.
I have an ubuntu 7.10 ICS server that works fine and I have routed my traffic using firestarter to my windows PC. my server's IP is 192.168.0.1 and my windows client is 192.168.0.2. now, I have bought another PC and I want to assign 192.168.0.3 to it and connect it to ubuntu server. in windows, all I needed to do was to connect the first client to first network card, second one to second network card, bridge two connections in my server, assign 192.168.0.1 to the network bridge in my server and 192.168.0.2 and 192.168.0.3 to my clients, then share my internet connection. I also could access shared files in any computer from all of them. can I have the same functionality with a linux server?
I'll make a list to make it easy if you don't wanna read the whole post:
things I want:
1. assign one ip address to multiple interfaces in linux, making them bonded.
2. sharing the internet connection with both clients.
3. ability to use all shared files over a network.
