I can bypass our firewall in IE. They use wildcards, like 10*. I've tried 10.100.0/16, but am still getting to our firewall. How can I specify the correct settings for Firefox?
View 4 RepliesI know this isn't directly related to Ubuntu (even if the rest of my network is pure Ubuntu!), but I haven't had any luck uncovering this info through the usual channels. Does anyone know which port Android 2.2 on a VIA wm8650 uses to access the Internet? My Wifi is routed through a Linux firewall (Ipcop) which forces normal outbound Internet traffic via normal ports (80, 8080 etc) through the ipcop proxy, but the wm8650 somehow bypasses the proxy. I don't know whether I'm just missing the port the tablet is actually using.

1. Create a own proxy in there box who has the internet access.
2. Other users use those box as proxy and access to the internet.
I've been trying to make myself anonymous, but I cant find 'Tor' anywhere, tried 'yum & kpackagekit' neither have it.

View 3 Replies View RelatedI have done some research on the net and I am battling to find effective methods in other to bypass those irritating ISP traffic shapers. I have used SSH tunneling to reduce latency (which is my primary goal, i dont care about silly torrents, etc) by about 200ms.
Do you know of any other way that I could improve this latency? When I ping my server in Germany (from South Africa) i get a latency of about 185ms... I was hoping to get online gaming traffic to around about 250ms or even less if possible... Right now its sitting on 550ms WITH SSH tunneling and 800ms without it... (to Blizzard servers)

At 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.

View 3 Replies View RelatedIs it possible to set a proxy server for every user without manually configuring firefox for each individual user?
View 1 Replies View RelatedI use Fedora 14 and Firefox as my web browser. I use Astrill VPN service. I have the following persistent problem: I start my computer. Astrill is not set to start on boot. I start Firefox. Firefox can not connect to anything, it says 'proxy server refusing connections'. I go to Edit>Preferences>Advanced>Network>Settings I click the radio button 'no proxy'. The problem remains. I am completely unable to connect to the net. Even on reboot, I cannot connect. On reboot, Firefox is set to use a proxy, although it was not on shutdown. Some init script is setting this. My normal connection is often faster than through Astrill, so I only really need to use it when I want to get at a website that is blocked by the govt here in China.
where Firefox is being told to use a proxy, and how to reset it to not use a proxy, assuming Astrill is not active. There must be something left in a .conf file somewhere which is overriding the settings in Edit>Preferences. Because, if I set it now to 'no proxy', I cannot connect to the net.
I'm using Ubuntu 10.04, and starting a SOCKS proxy with 'ssh -D', and setting Ubuntu to use it with "System -> Preferences -> Network Proxy". Firefox uses the proxy, and the proxy's IP appears when I visit a site like [URL]. is Firefox resolving DNS requests through this proxy? Is my web-browsing truly secure? (That is, until I exit the other end of the proxy.
I know it's insecure after that.) (And I've verified the keys, I'm not being man-in-the-middled) (And--screw it. You know what I mean. Is it resolving DNS requests through the proxy?)I don't know how I would go about verifying such a thing for myself.Using additional hardware such as another debugging proxy is not an option. If Firefox isn't resolving my DNS requests through the SOCKS proxy, how do I go about fixing it?
I'm looking for a distro that has the things i want in it like VLC, Oprea, Firefox, freenet, KTorrent, proxy programs. Only problem is i searched everywhere and can't find anything.

Does anyone know of a place that has an ISO for liveCD with all the stuff im looking for or a place i can make what i want with the items i want? Any info would help thanks for taking your time out to read this.
View 6 Replies View RelatedI am on Linux on machine LOCAL (my notebook).I ssh into a company machine REMOTE which is behind a firewall and ONLY allows incoming ssh connections (port 22), no outbound connections whatsoever. I do have full root access on both, LOCAL and REMOTE, REMOTE is however a VPS and behind a hardware firewall.I now need network access on REMOTE (HTTP and other protocols) for downloading and building some software. I also need to access to NON HTTP protocols such as git.
I was hoping to set up a reverse SSH tunnel for using my LOCAL machine, where I could be running a socks server. So that network access on REMOTE would be redirected over the SSH tunnel to a socks server running on machine LOCAL.How would I go about setting something like this up?
I was under the impression the Linux (in my case the Fedora OS) is very secure. However I've learnt with deep concern that that one can have access to the system during system startup i.e one can give various startup directives and bypass the normal login UI to have direct root access.
Is there a way to disble this so that the directives during startup are fixed and cannot be altered. I would like to make the system secure to the maximum extent possible.
Ive installed fc11 on my laptop (IBM lenovo R400). My work has a proxy which we must go through. I have set the proxy addresses in System Settings->Network Settings-> proxy. I have also run export [URL].. All seems to be ok, yum works from the command line, konquer goes out to the net just fine. However firefox wont connect to the internet no matter. The only way at the moment is to manually set the proxy in firefox.This doesnt seem right? Surely FF should pick up the system proxy? Does anyone have any ideas about this one?

I setup a SSH server on my computer on a very high port, so that my brother could surf the web through my computer from Iran, since the majority of websites are filtered there.
Today, he told me he cannot connect to my computer. That's why, I got suspicious that they are doing packet based filtering instead of port. Then I decided to change the port to 433 for https, but one of my friend told me that they just banned https in Iran as well.
I was wondering if there's any way I can manipulate SSH packets between two computers so that my brother's ISP won't figure out he's exchanging SSH packets?
I have a user that has already used up a demo 24hr trial on my website. At present, I only check the customer id and the IP address to search for duplicates. On the whole this works but it's not foolproof. We now have 1 user from China that is changing their IP address everyday to get access to the free trial. Any options on what to do? I thought of downloading a cookie to their computer that the website could pick up - again not foolproff but most people don't disable cookies. Any other options?
I could ban China temporarily until the user gives up but if they find another proxy to chain then their IP address will be different again.
I am looking for a way to permanently delete files immediately - no trash, no taking up space but a command to make a file immediately gone.

I 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 ?
