17.04 - proxychains can't resolve DNS

Question

I am using Kubuntu 17.04 and I installed proxychains which worked like a charm on Kali Linux.

In /etc/proxychains.conf I commented line that returns strict_chain and uncommented line that returns dynamic_chain. Everything else is defaulting.

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

then I ran proxychain google-chrome and I would get warnings such as:

!!!need more proxies!!!
|DNS-request| www.googleapis.com 
|DNS-response|: clients2.google.com does not exist
|D-chain|-<>-127.0.0.1:9050-<--timeout

I also tried these:

proxychains curl https://google.com

output:

ProxyChains-3.1 (http://proxychains.sf.net)
|DNS-request| google.com 
|D-chain|-<>-127.0.0.1:9050-<--timeout

!!!need more proxies!!!

|DNS-response|: google.com does not exist
curl: (6) Could not resolve host: google.com

or ping;

proxychains ping https://google.com

output:

ProxyChains-3.1 (http://proxychains.sf.net)
ERROR: ld.so: object 'libproxychains.so.3' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.
ping: https://google.com: Name or service not known

Solution

As far as I know, proxychains only works with TOR.

After trying some other options I posted in the comments, the solution was in fact:

sudo apt install tor

After installing TOR , proxychains works as expected.

In backtrack , proxychains is using TOR on 127.0.0.1:9050 . Your other errors suggest DNS is not working, so try either specifying an ip such as 8.8.4.4 rather than google or install TOR. IMHO TOR is best installed as part of the tor bundle from the tor project rather than from the ubuntu repos, but up to you.

@Panther is there a way to make it work by avoiding TOR IP addresses overall? I tried commenting out TOR address and I added socks4 5.9.212.53 9559 socks4 89.169.1.81 80 http 221.181.34.74 82 socks4 61.147.67.2 to the config file. Problem still remains. As for DNS warning, I am also using Kubuntu 17.04 on my laptop which doesn't have this warning but problem above remains.

[Panther]

Can you ping google.com and 8.8.4.4 ?

[Panther]

As far as I can determine it requires TOR.

[Panther]

does not using proxy chains without tor sort of defeat the purpose ? Perhaps I can give you an alternate .

[Panther]

Try this linuxbabe.com/desktop-linux/…

[Kunok]

@Panther I will try to ping these when I reach my PC. As for Tor, I tought Tor is just one of many services that provide their proxy. I used proxychains on Kali without any additional installations but that may be just because Kali comes with many tools and configs preinstalled

[Panther]

OK, good luck to you, I have tried many configuration options and I can not get it working without TOR. Please post a solution if you find one.

[Kunok]

@Panther hey I didn't want to bother with configurations anymore because I only needed proxychains for simple task and I didn't really need true anonymity, so I just did sudo apt install tor and everything works well now. Can you post it as answer so we can close this thread?

This didn't work for me, same error
