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?
View 2 RepliesI 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.

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.

View 9 Replies View RelatedAt the moment I have a proxy and all the users have to configure it in the browser to access internet. I want to make the users able to browse even without configuring the proxy in the browser. but eventually it should be received in the proxy rather than giving an error to the user. I heard with transparent proxy I can redirect all the traffic from a particular network, to a particular host( ie my existing proxy).
I tried this using firewall rules. But then the existing proxy doesn't understand the protocol of the requests. I heard that it should be in the kind of proxy protocol.
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.

View 8 Replies View RelatedI am trying to set up my squid3 proxy as a transparent proxy - right now, I have to manually configure browsers to access via proxy. I understand that I have to put some rules into Iptables and also some further directives in the squid.conf.
I have a couple of specific questions. The proxy server is running on a Ubuntu 10.04 workstation and this machine also acts as a dhcp server for the network. I have just one subnet , namely 192.168.0.1-254 There is only 1 network card. Is it much easier to put in a second network card or is it just as easy to configure the existing lan card as a dual IP?
Is it necessary to configure these 2 IP's ( whether they are via 2 lan cards or dual IP on single card ) to be on different subnets. i.e ETH0 192.168.0.1 and ETH1 192.168.1.1 or is ok to have something like ETH0 192.168.0.1 and ETH1 192.168.0.254 ( where ETH0 is the one facing the LAN and ETH1 points to the modem router / switch i.e The Internet ) Where specifically do I save the Iptables rule configuration file and what must I call it ?
I've been doing some security testing in a lab environment that does not have direct internet access. It's actually a little complicated: From home to connect to my lab machine, I
1. SSH to machineA.
2. SSH from machineA to machineB
where machineB is my actual lab machine. neither machineA or machineB allow anything other than SSH, and machineB is only accessible from machineA. However, I really need to run yum on machineB. I have managed to get internet access via Firefox on machineB by creating a series of SOCKS proxy via SSH.
1. machineB: ssh -L 12345:localhost:12345 user@machineA
2. machineA: ssh -D 12345 user@machineC
3. machineB: configure firefox to use socks proxy, localhost, 12345
where machineC has internet without limits placed. This is the only way I have managed to get internet working. I tried using ssh -L all the way from machineB->machineA->machineC but it didn't work (even when setting Firefox to use http proxy). I tried using ssh -D all the way, but again that doesn't work either.
I do have access via Firefox using socks proxy. However, yum update fails to retrieve mirror list, and from what I have found I don't believe yum supports socks proxy directly. Instead, it uses http_proxy / ftp_proxy. how to get yum to go out over the SOCKS proxy I created (same one using in Firefox)? It seems like since Firefox can access the internet and everything without issues, i should be able to get yum to tunnel through the same connection to access everything.... I tried

is there a way to force wget to use a specific squid proxy when making connections ? - I use a squid proxy normally, but I need this specific request to go via a different one. I dont have to use wget, I just need a way to test squid's blocking rules by requesting various pages through it, this proxy is not my normally proxy on the network and so I cant rely on wget taking the environment variable.
Also, this is as part of a script, so anything that avoids editing wget config files would be best. - Perhaps curl can do this ? - currently im using the exit code of wget to determine if the connection was made.
I'm having an issue on multiple Lucid boxes where I can't get proxy ARP to work. This is to be used in conjunction with openswan IPSec. I've enabled forwarding and disabled sending/accepting ICMP redirects for each interface as per openswan's requirements. I've added the proxy arp lines for all, default, eth0, and lo to sysctl.conf:
Code:
net.ipv4.conf.eth0.proxy_arp = 1
I then connect the IPSec client, and I have connectivity to the server. When I try to ping (or otherwise access) something else on its subnet, I reach the intended target, but then it ARPs for the sending machine, and the Ubuntu server doesn't respond to the ARP.
I have an ARP entry that looks like this, added via arp -s 192.168.254.100 -D eth0 -i eth0 pub:
Address: 192.168.254.100 (the correct virtual IP for the client)
HWtype: *
HWaddress: <from_interface>
Flags Mask: MP
Iface: eth0
Best I can tell, everything is in order... I can listen in with wireshark on the server and see that it's receiving the ARPs, but I can't get it to respond to them.
I have been struggling to configure a squid proxy server on my ubuntu 11.04 VPS.
Following these instructions[URL].. it is all good BUT I don't want to have to SSH tunnel into the server. Just want to have a proxy set in my proxy server settings in firefox/chrome. Even lock the proxy to certain static IP addresses so no one else can use it except IPs I designate.
1. Can this be done without a VPN or SSH tunnel ?
2. What is the best way to put some security on the proxy server ?
I'm behind a very blocked firewall that only allows connections through port 80 and 443. I wish to ssh to my machine at home, but the port is blocked. Is there a simple server that I can run to route my ssh connection through http?
