    Question Proxychains

    Ladies&Gents,

    Distro --> BT5R1 (Gnome)

    I've a situation I'm hoping someone can provide some guidance on. With BT4R2 proxychains and firefox worked just fine together. This is not the case with BT5R1.

    Last night I was attempting to use proxychains and firefox on this newest release of Backtrack when something strange happened. The command I used was
    Code:
    proxychains firefox
    Instead of proxychains working inconjunction with firefox, it just launched firefox, that was it. No proxying of anytype occured.

    I know what some of you are thinking, so let me disparge that falsehood right now. I am not using TOR.

    I am using a proxy server out of Tampa for a company I am currently PenTesting for. Their firewall rules prevent access to the internal network unless you are within a certain IP address range. It just so happens that they have a very misconfigured proxy server that allows access to their internal networks. It is supposed to work inconjunction with their VPN as an "added" layer of security.

    I've verified that proxychains WORKS because I am able to make connections using proxychains to the telnet/ftp/ssh servers they have running behind that firewall. The stage of the test I am currently on is trying to access their internal HTTP servers. I am able to receive output via curl and wget through the use of proxychains inconjunction with telnet/ftp/ssh, however active webbrowsing is not available to me because of the error I am having with proxychains + firefox.

    I'm betting on the fact that perhaps the way in which firefox is installed or the version of firefox (5.0.1 I believe) has something to do with this whole error. I will test this tonight and report back.

    Does anyone else have suggestions?


    V/r,

    Pffbt..
    I made a discovery today. I found a computer. Wait a second, this is cool. It does what I want it to. If it makes a mistake, it's because I screwed it up. Not because it doesn't like me... Or feels threatened by me.. Or thinks I'm a smart ass..

    Is Tor really included in the new backtrack 5 r1 distro? I only use backtrack 5 r1 as live dvd and when I do /etc/init.d/tor start I get only the reply
    No such file or directory.The same goes for privoxy.

    proxychains firefox,nmap,....eccc
    look in my firefox /preference/network/settings is autodetect-proxy-setting for this network!

    zimmaro,

    While I appreciate the insight on TOR, I need to clarify something, so...Let me quote myself for a minute
    I know what some of you are thinking, so let me disparge that falsehood right now. I am not using TOR.
    I could care less about TOR

    I'm trying to find the reason why proxychains just launches firefox and does not PROXY for firefox, it works with telnet, ssh, ftp, etc....

    snafu777,

    instead of trying to use tor + proxychains + firefox there is an easier way, and proxychains shouldn't be used with firefox. Okay when you install tor you need to
    setup either privoxy or polipo to work with a web browser such as firefox. I would recommend Polipo because it works faster than privoxy, you will still have a
    lag on your web browser, it just won't be as bad as privoxy. Okay so make sure that you have tor+polipo running, and just tell firefox in the advanced settings to use your polipo running at 127.0.0.1:8118 on localhost port 8118. You can verify that polipo is running with the command "netstat -ntl" make sure you see that
    port 8118 running it should look like this:


    Active Internet connections (only servers)
    Proto Recv-Q Send-Q Local Address Foreign Address State
    tcp 0 0 127.0.0.1:8118 0.0.0.0:* LISTEN


    Now just add that to firefox advanced manual proxy setting or you can use the "foxyproxy" add-on if you would like. Its simple easy, and it works...

    Now, please remember that if you are going to be using tor and other proxy apps to "not be and idiot" and only do things under the law.

    Ladies/Gents,

    The solution has been found. Devs, Please close this post.

    To properly run proxychains in conjunction with firefox, there must not be a currently running instance of firefox. When I was trying to use it yesterday, I already had one instance of firefox open in the background. I tried it last night with no running instances, and it worked perfectly.
