Given information: I have root access to a machine on ip 1.1.1.1 and open up port 22. Instead of having to log into the machine again through an exploit to get root access AND to not install apps onto their machine (If i created a reverse shell on the machine, it could get detected), figured to try a new approach; port forwarding and proxy chains. The idea I had was to set up a tunnel to the webserver and just forward the information along in order to start mapping out the internal network. I stumbled across proxychains, which is as simple as configuring the port, say 8080 in its conf file, then running commands: proxychains ifconfig and then proxychains nmap --script=discovery $ip There seems to be some configuration needing to be done before you can use Proxy chains and this is where I think *why?*. I will append below. So, firstly as root access on the webserver, I will open port 22 and make a user with admin permissions, say *jakefromstatefarm*. Then I will from my attacking machine do the following: ssh -f -N -R 2222:127.0.0.1:22 jakefromstatefarm@1.1.1.1 # Enter password for jakefromstatefarm ssh -f -N -D 127.0.0.1:8080 -p 2222 atkMachineUser@127.0.0.1 # Enter password for atkMachineUser Now I would use proxychains on port 8080 by editing the conf file proxychains ifconfig My question which confuses me is why do we need to set up these sets of tunnels prior to? Is it because of the required user credentials to speak to the different machines? That way, the machine will maintain the credentials and then from there proxychains doesnt need to maintain anything? I was confused because i was not sure why I couldn't in theory set up proxychains to use port 22 to talk to the webserver at 1.1.1.1 directly and run its respective commands. I am trying to make sure I understand SSH Tunneling correctly. I read a bunch of information, wiki pages and books, and while i vaguely understand some concepts, i dont have a warm and fuzzy quite yet. That being said, Id love it if someone could explain it to me like i am 5, or well, with less mumbo jumbo.

I hope my question make sense So I have a JumpServer that has a VPN connection to another subnet ex. 10.x.x.x. This subnet is only accessible via JumpServer. So I can connect to 10.x.x.x from my local machine by using socks proxy: - ssh root@JumpServer -D 9999 - Add config on /etc/proxychains socks5 127.0.0.1 9999 then proxychains ssh root@10.x.x.x When I perform proxychains SSH, the local address of 10.x.x.x is 192.x.x.x. and I discovered some hosts From my local machine, how do I connect to the local address of 10.x.x.x basically the chain is 127.0.0.1:9999 ... 10.x.x.x:22 ... 192.x.x.x:PortNumber?

After some research, I didn't find any solutions. So I post here. **My goal:** redirected the HTTPs traffic from my custom program to BurpSuite in order to analyse the server response and debug my program. - I have Debian 4.4.3 - I have two network interfaces : eth0 and tap0, I work on tap0. - I have a php program that just send an HTTPS request to a local server (tap0). My php code use CURL to send the request (curl_init(), curl_setopt() etc.) In a debugging goal, I have thought to send my flows via BurpSuite in order to see the HTTPS requests. So: - I launch Burp that listen on all interfaces port 8080 - I configure /etc/proxychains.conf and in my ProxyList there are: socks4 127.0.0.1 8080 socks5 127.0.0.1 8080 socks4 XX.XX.XX.217 8080 socks5 XX.XX.XX.217 8080 And when I use proxychains: prochychains php myProgramme.php My program is executed but proxychains doesn't "proxify" the flow and so Burp doesn't see nothing... I think that's because I am in my local network ? What do you think about the best solution to intercept and see the HTTPS flows to my php program ?

Let's say, I have dynamic_chain set and have two proxies in the chain list:

[ProxyList]
socks4  127.0.0.1 9999
socks4  127.0.0.1 8888

Both proxies can reach the server aa.bb.cc.dd. When I run the following command:

proxychains ssh aa.bb.cc.dd

How will be the route to reach aa.bb.cc.dd? Will it pass by 127.0.0.1:9999 and then by 127.0.0.1:8888 and finally to aa.bb.cc.dd? Or it will go directly from 127.0.0.1:9999 to aa.bb.cc.dd? Or it will go directly from 127.0.0.1:8888 to aa.bb.cc.dd? I am much confused about this. Can any friend show me what the actual case it is? Many thanks!

I am able to access internet only behind a proxy 172.16.24.4:3128. When I run proxychains with proxy given by Tor, then my proxychains works fine, but when I run proxychains with the proxy through which I access the Internet (i.e. 172.16.24.4:3128), the proxychains don't work. Here's the sorts of errors I get: proxychains apt-get update ProxyChains-3.1 (http://proxychains.sf.net) Err http://dl.google.com stable InRelease Err http://dl.google.com stable Release.gpg Could not resolve 'dl.google.com' Err http://security.kali.org sana/updates InRelease Err http://dl.bintray.com jessie InRelease Err http://security.kali.org sana/updates Release.gpg Could not resolve 'security.kali.org' Err http://dl.bintray.com jessie Release.gpg Could not resolve 'dl.bintray.com' Please help. I am having this issue for a year and I couldn't find a solution. I think the problem is with DNS lookup behind a proxy. I don't know I have tried everything. Nothing works. One more thing. If I set http_proxy variable to 172.16.24.4:3128, then also some of my applications work, so there's nothing work with the proxy.

I have my proxychains configured as strict_chain proxy_dns http 172.16.20.2 3128 because I can access internet through 172.16.20.2:3128. But running the proxychains gives me the following error root@kali:~# proxychains apt-get update ProxyChains-3.1 (http://proxychains.sf.net) 0% [Working]|DNS-request| http.kali.org 0% [Connecting to http.kali.org]|S-chain|--172.16.20.2:3128--4.2.2.2:53-<--denied |DNS-response|: http.kali.org does not exist Ign:1 http://http.kali.org/kali kali-rolling InRelease 0% [Working]^C So, what's wrong? I suspect nothing is wrong with my proxychains because it runs on tor but not on 172.16.20.2:3128. 172.16.20.2:3128 runs fine on my browser so what prevents it from running on proxychains?

I am trying to set up a proxy and every time I try to use it it denies me or times out. I tried every thing. Tor is up and running properly. My system is fully updated and I'm on Kali Linux. Sometimes it won't even go through. root@kali:~# proxychains iceweasel ProxyChains-3.1 (http://proxychains.sf.net) (process:9547): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed |DNS-request| www.kali.org |DNS-request| tools.kali.org |DNS-request| www.offensive-security.com |D-chain|--127.0.0.1:9050--127.0.0.1:9050--127.0.0.1:9050--4.2.2.2:53-|D-chain|--127.0.0.1:9050--127.0.0.1:9050--127.0.0.1:9050--4.2.2.2:53-|D-chain|--127.0.0.1:9050--127.0.0.1:9050--127.0.0.1:9050--4.2.2.2:53--127.0.0.1:9050--4.2.2.2:53--127.0.0.1:9050--4.2.2.2:53--127.0.0.1:9050--4.2.2.2:53--127.0.0.1:9050--4.2.2.2:53--127.0.0.1:9050--4.2.2.2:53--127.0.0.1:9050--4.2.2.2:53-<--timeout <--timeout |DNS-response|: www.offensive-security.com does not exist here is my proxy config: # proxychains.conf VER 3.1 # # HTTP, SOCKS4, SOCKS5 tunneling proxifier with DNS. # # The option below identifies how the ProxyList is treated. # only one option should be uncommented at time, # otherwise the last appearing option will be accepted # #dynamic_chain # # Dynamic - Each connection will be done via chained proxies # all proxies chained in the order as they appear in the list # at least one proxy must be online to play in chain # (dead proxies are skipped) # otherwise EINTR is returned to the app # strict_chain # # Strict - Each connection will be done via chained proxies # all proxies chained in the order as they appear in the list # all proxies must be online to play in chain # otherwise EINTR is returned to the app # #random_chain # Random - Each connection will be done via random proxy # (or proxy chain, see chain_len) from the list. # this option is good to test your IDS :) # Make sense only if random_chain #chain_len = 2 # Quiet mode (no output from library) #quiet_mode # Proxy DNS requests - no leak for DNS data proxy_dns # Some timeouts in milliseconds tcp_read_time_out 15000 tcp_connect_time_out 8000 # ProxyList format # type host port [user pass] # (values separated by 'tab' or 'blank') # # # Examples: # # socks5 192.168.67.78 1080 lamer secret # http 192.168.89.3 8080 justu hidden # socks4 192.168.1.49 1080 # http 192.168.39.93 8080 # # # proxy types: http, socks4, socks5 # ( auth types supported: "basic"-http "user/pass"-socks ) # [ProxyList] # add proxy here ... # meanwile # defaults set to "tor" socks4 127.0.0.1 9050

To utilize the proxy on my Ubuntu system, I required the installation of proxychains. Here are the steps I took: 1.

sudo apt-get install proxychains
 2. 
    sudo vim /etc/proxychains.conf
    ...
    [ProxyList]
    socks5 192.xxx.xxx.xxx 1080
    
 3. 
sudo vim /usr/bin/proxychains
    ...
    #export LD_PRELOAD=libproxychains.so.3
    export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libproxychains.so.3
    
Then I run proxychains curl www.google.com, the proxy doesn't work but there's no error.
When I run sudo proxychains curl www.google.com, there's the error:
ERROR: ld.so: object '/usr/lib/x86_64-linux-gnu/libproxychains.so.3' from LD_PRELOAD cannot be preloaded (failed to map segment from shared object): ignored.
ERROR: ld.so: object '/usr/lib/x86_64-linux-gnu/libproxychains.so.3' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.

How can I fix this issue and run proxychains successfully? Thanks a lot.

I am using Ubuntu 5.15.0-57-generic and I see many people have a problem with proxychains where they get this error:

"ERROR: ld.so: object 'libproxychains.so.3' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored."

I get the same error and the fix is easy to look up. I just need to change the relative path in /usr/bin/proxychains to an absolute path. It seems like everyone else has no trouble with this, but no matter what I do the file looks the way most bin files look when you cat them:

@@@#%^$@%^&@#@@@@@@

Like that, if you know what I mean. The only thing that I could do was to add export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libproxychains.so.3 to /usr/bin/proxyresolv but that did nothing. I have tried to change the files in /usr/lib/x86_64-linux-gnu that might be relevant: libproxy is a directory that goes deeper than I want to mess with so I left it alone; libproxychains.so.3, libproxychains.so.3.0.0, libproxychains.so.4, libproxy.so.1, and libproxy.so.1.0.0 all give me gibberish, and p11-kit-proxy.so gave me the crazy screen pic I attached just for fun because I have never seen it and can't get out of it no matter what I do. (Also, as you can tell from the above, I tried to just use proxychains4 when I saw someone say that it did not have this same issue with the relative path name, but no dice). Anyway, I would love to get proxychains working, but I would love just as much to know why other people can cat /usr/bin/proxychains and get a nice and clear and editable #!/bin/bash file while I get nonsense. Here is the main post that I was trying to follow: https://stackoverflow.com/questions/63081456/error-ld-so-object-libproxychains-so-3-from-ld-preload-cannot-be-preloaded

I did the same steps in Parrot OS, and its working. Here in Kali I couldn't find what's going wrong.

Trying to get proxychains setup using vm with kali, i enter proxychains firefox google.com into terminal and after a while firefox says timeout, is this to do with the proxy server being down or smt else.

On terminal when i use proxychains firefox it is getting terminated instantly by showing this.

I've been trying to run a wallet app in tails os ver 4.28 with no success. I'm getting denied error when using it with proxychains.

Any help is appreciated.

sqlmap -u http://192.168.0.106/get_method/get_data/?id=1 --dbs I know that if we sent any request to any server that server takes ip address of user(mine). So, while I am running the above source code server is getting my ip address. So, they can easily find me. ~ I am not sure of the information also. In Kali-Linux, there's something called proxychains.conf. I was trying to use that proxychains4 sqlmap -u http://192.168.0.106/get_method/get_data/?id=1 --dbs But, proxychains not working I am saying that by [proxychains] Dynamic chain ... 127.0.0.1:9050 ... 192.168.0.106:80 <--denied. I am getting data by above code also but, not using different ip addresses ~I think I am not sure of it also. So, I want to change my ip address every moment when I works with sqlmap or any other vulnerability. I am totally Newbie.

I was running proxychains [this way](https://unix.stackexchange.com/a/640536/449077) . I am getting different ip addresses each time. But, now the problem is when I run any application without that command (proxychains4 firefox) than I get my real ip address. So, I want to set dynamic ip globally. If I run proxychains than ip addresses should be change everywhere. In this [link](https://linuxhint.com/proxychains-tutorial/) they run nmap this way(`proxychains nmap 192.168.1.1/24 `) But, I want to run nmap(any application) without proxychains that's why I have to run proxychains globally but, how?

sudo nano /etc/proxychains4.conf Dynamic chain is open. Then, I #/comment others(strict chain,random chain,round robin chain) Another changes I made socks4 125.26.99.2 44052. Then, I run proxychains on firefox proxychains firefox google.com After few minutes : They are loading loading and loading................. I don't know why this is happening. Those websites aren't opening... My proxychains filename is proxychains4 that's why I thought it would work if I run the following command proxychains4 firefox google.com Nonetheless, I am getting same error

I use proxychains utility with firefox. I want to start the firefox profile twice, but with other proxychains parameters. But I can't, when I try to run the second instance of firefox with the same profile, it's just opens a new window of exiting session. I have tried this commands: firefox -P profile %u, firefox -P profile --new-instance, firefox -P profile --no-remote, firefox -P profile --new-window. Nothing worked. Hope for your help!

[Here](https://pastebin.com/FiXiPJ4R) is my config file. The proxy I use for testing comes from [here](http://free-proxy.cz/en/proxylist/country/GB/https/ping/all) . *I don't want to use Tor.* I just want a normal proxy. When I run for example proxychains firefox-esr ipleak.net: * if I use exactly the config file from above, I get the error:

error: invalid item in proxylist section: https 185.198.189.21 8080

* if I change https to http, I have no error in my terminal, the browser starts, but the page won't load and gives me an error after some time: What am I doing wrong?
