An application that supports SOCKS 5 protocol can forward its network connection over ssh and dynamically forward to any host name that you specify isn't it ? that means firebox web browser can use SOCKS 5 protocol can be used by pass proxy settings isn't it ? so how can a sys admin remotely detect if a particular user is bypassing proxy settings using SOCKS 5 protocol ?
View 1 RepliesI have been ssh tunneling, which works great.I can browse the internet by simply tunneling my traffic through my SSH server.the following command: ssh -ND 9999 username at myserver.i cant postlinks.is all I have type, and I can connect to a SOCKS proxy server on localhost:9999.My problem is that I have an application that only supports HTTP proxies.Is there any way I can get it tunneling over the socks proxy?

I've opened an SSH Tunnel/SOCKS proxy on my Ubuntu server, which I've tested is working exactly as I had intended. However I'd like to access it from my Windows PC which is on the same home network.
Edit : I should say that I got it working on the server only by
Code:
ssh -D 55555 user@host
However if I tried it with a port, e.g.
Code:
ssh -D 192.168.1.101:55555 user@host
then it doesn't work, not even on the server itself. 192.168.1.101 is the static assigned DNS of my server on the home network.
How can I use socks proxy which is on a remote machine?

I downloaded freeSSHd [URL] on my Windows XP SP3 PC and configured the firewall to allow port 22. My grander scheme is to use this Windows PC as a SOCKS proxy server, that I can connect to at school to circumvent internet filtering and keep my data private. Does anyone know of a way that I could somehow get every internet-connected-program/service (chats, email, browsers, etc) to use this encrypted connection without having to configure every program individually? I think this link is on to something, but I'm not certain what he's getting at [URL].
View 1 Replies View RelatedI 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 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.

Can Tor be configured as a socks proxy? Would it change the IP even if the user was loading a java applet?
I want to generate my own socks 5 proxy not for lan but for my use on internet I want to access that proxy from any pc and any connection. Like proxy supplied by atomintersoft.com or xroxy.com i want to create my own 300 socks 5 proxy. I can have dedicated server if required to do so.
1)tell me steps to create my own socks5 proxy.What are general system requirement.
2)Which Distro will be best for this purpose.I am new here and dont have idea about linux but can grasp everything faster than u!
what is the command to sftp from one linux host to another linux host through a SOCKS v5 that requires authentication? I have tried:

I know this does not have auth in it but I was going to come to that later
output

What I dont want is them to pointlessly use it for other browsing.I trust my friends wont, but is there also a way of checking they arent using my connection to download illegal torrents?I guess best case scenrio would be to be able to whitelist only a few sites per user request. Is this possible?

View 1 Replies View RelatedI've read the documentation, but I'm still confused. I have two servers, one running Postfix and SquirrelMail, and another i want to setup a wiki(already setup) and Photo Gallery.On my Second server(2)I have two virutal webservers, wiki.rmasonfamily.info and photo.rmasonfamily.info, both running on port 80.My first computer is running my mail server again as a virtual server, mail.rmasonfamily.info. Default server is not used in either one.
Server 1 will be my proxy server, and if I understand correctly, my reverse proxy. Ubuntu had Apache set with a configuration in etc/apache2 using sites-available with configuration for each Virtual Server with sites-enabled with links to configuration files in sites-available. My Virtual Server in Server 2 are working fine, along with my mail server in Server 1. this is the code I assume I must use to bypass to wiki.rmasonfamily.info.

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 am making a content filter for a school. I have a computer with Ubuntu Server and the SOCKS proxy, a DD-WRT router, and a switch. how I could forward all requests through the SOCKS proxy before sending it to the Internet.

My company web access is behind proxy(http://abc.proxy). Network admin can get to check who is top10 user and web they access. I owned a centos server. I have a thought that create an encrypted tunnel within proxy so the admin cant detect my http address. This is how it going to works
client with OpenVPN -> OpenVPN server(centos with company proxy)-> proxy -> internet
My connectivity in my client are using OpenVPN server as bridge. Hence, no record for client is recorded in my Network admin monitoring list. OpenVPN server's activity can be traced by network monitoring tools, just assume that our ultimate goal is to hide client activity.
I've got my netbook set up so that I can run a SOCKS proxy via my desktop machine. This works fine at home, but I'm wondering what happens at an internet cafe with public wifi.
Specifically, the connection needs initially to be set up with an ordinary direct internet connection so that I can log in to the cafe's router. I'm concerned that when I then set the network proxy to SOCKS host, the router will cease to recognise me and will disconnect me. This particular detail doesn't seem to have been covered in any instructions that I've seen (maybe I haven't looked hard enough).
I have an interesting situation. I'd like to use bittorrent for legitimate purposes (mainly linux distro based) but the powers that be have blocked access to bittorrent at my university. I have an ubuntu VPS that I use for odds and ends and was thinking that I could setup a SOCKS5 server on it. That way, I can input the SOCKS5 info directly into the proxy section of my local bittorrent application (Transmission 1.92 running on snow leopard) and be good to go. The problem, however, is that I cannot find a way to get a SOCKS server up and running on my VPS. I've heard that ssh can be used as a simple SOCKS server, but I've also heard that i may need to install a more complete SOCKS server such as dante. Does anyone have any thoughts on this?
