General :: Set A Proxy On PC?
Nov 15, 2010
My employer blocks allot of sites i like to visit.nothing too kinky, just security related and some other sites.I would like to set up a proxy server on my own machine, because i can access it from work. what I'm looking for is a server that listens on port 80 and maybe has some web interface so i could type the address in instead of config my browser with the proxy.something like boratproxy.comi use fedora 14.optionnumber two is the same requirments that i can install at my web hosting provider

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've been trying to make myself anonymous, but I cant find 'Tor' anywhere, tried 'yum & kpackagekit' neither have it. I did find 'Privoxy', installed it, set proxy for HTTP and HTTPS in Firefox, but it says 'unknown proxy' when I try to use it! I've been to the Privoxy web site and read through the 'User manual', but most of it is 'geek' to me!

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 ?

I am working on fc10. I connect to internet using two connections: with proxy and without proxy. Initially I had some problem in configuring yum for proxy and I resolved it by creating files proxy.sh and proxy.csh in /etc/profile.d with the required details (export_proxy).Now when I connect to my connection without proxy I have some problems .Whenever I try to do yum update I get the following error:
"[URL]: [Errno 12] Timeout: <urlopen error timed out> Trying other mirror. Error: failure: repodata/primary.xml.gz from adobe-linux-i386: [Errno 256] No more mirrors to try." what changes do I need to make in order to use yum in the connection without proxy?

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.

I have socks proxy running on port 1080. I want other people on LAN to use this proxy. How can I do that?
One way is that the client can run this command and then use proxy 127.0.0.1:1080 on his computer:
ssh -L 1080:127.0.0.1:1080 myusername@myipaddress
But, I dont want to use ssh because that requires me to give my password to others.

Is there a way to SSH into a server (my home computer) from behind a proxy that has a username and password? I read about corkscrew, but I was wondering if there is a simpler way.

just a quick question. I was wondering if it is possible to do the following: suppose there is a www and it contains 3 pages: aboutus.php, index.php and contactus.php within each side there are 3 other pages you could say 1*.php,2*.php,3*.php, where * stands for any of {aboutus,index,contactus}. I was wondering how, if it is possible, to implement the following mechanism.
If users requires 2a.php go to aboutus/2aboutus.php or if it is 1i.php then go to index/1index.php. What this does it translates addresses that user requires into the original links that are stored at the server. Then, if I want to change the translation I just change the naming convention say 22a.php or 11i.php and updates my mapping mechanism. Is it possible to implement it with mod_proxy_http ? so that you could dynamically (at once, without restarting apache and without any delays) change this mapping to whatever you want ? maybe there is another module I should look at ? Or shall I implement it myself?

I have setup a Squid Transparent Proxy that works and I can connect to most websites and block-list works and yadda yadda yadda.
My problem is that when I try to connect to a certain PC it will not work. A bit more clarity...
[INTERNET]----[DSL-MODEM]----[ROUTER]----[SQUIDSERVER]----[NETWORK]
Connected to the DSL-MODEM is the PC in question that I can't connect to when using Squid. If I bypass the Squid from the Network and go through the router I can connect to the PC.
I want to be able to use the Squid server and still access the PC connected to the Modem and I want to have a Squid SAR report of the Network PC's accessing the PC on the modem.
The Modem/Router/Squid/Network all use the same IP range, but the PC on the modem has a different IP.

'm trying to access remotely to my computer that is in my home with a VNC client. The problem is that from my company site, I'm behind a proxy and I must use this proxy to connect my computer.I'm new to the vnc programs, so I don't know how to define a connection to use the proxy. My laptop is well configured, the only problem is set a vnc client to use a defined proxy. 1 - I've installed VNC viewer or tightvnc viewer, but I can't find any option in it to define a proxy. How can I define a proxy in this program?2 - Is there any vnc client that allows to define a proxy?3 - Should I define a tunnel that redirects my connection to my remote PC? For example, if I define a tunnels that from localhost:5656 it connects to my remotePCort through the proxy will I hane any problem

I am accessing internet through Analog Proxy. ADSL modem has been connect to one of windows xp machine and by running Analog proxy, we uses internet by mentioning that machine's ip address. But how do i ping the default gateway in this case? Is it possible or not? If yes then please tell me how, because if i says # ping <anysite.com> it not pinging; its says host unreachable; means i will not be able to run wget too.
I am trying to ping from OEL 5.3. In one of google link; i read that :Does PING work through the Proxy Server? No, ping uses the ICMP protocol to communicate. Proxy only supports TCP and UDP packets. Ping will resolve the DNS name but go no further.

I have recently installed tor + vidalia + privoxy on my maverick system. What I was hoping to do was set up transparent routing through tor using the instructions here - [URL] But Ive had no luck with any of the examples given. When Vidalia tries to connect it stops at the point of generating a tor circuit and never gets any further.

My aim was to build a VERY simple smtp proxy under debian to handle mail from a port (51234) and forward it to the standard 25 port. I compile and install a "delegate" witch can handle easily that. It's working very well like that : delegated SERVER="smtp://anotherSmtpServer:25" -P51234
The strange thing is, it's working on my virtual test machine and on the dedicated server in local but I can't manage to use it trought internet. I test it like that. telnet [mySrv] 51234 Of course, no firewal, no deny host, no ined/xined, the service delegated is listening on the right port ... 2 clues : The port is answering trought internet with nmap as "51234/tcp open tcpwrapped" have a look at the tcpdump following :
