Using CURL with TOR as a Proxy on CentOs

Question

I want to use Tor as a proxy for HTTP-requests with curl or wget on a CentOS Machine. I used this How-to and I looked for some answers on stackexchange and stackoverflow. https://medium.com/the-sysadmin/using-tor-for-your-shell-script-fee9d8bdef5c#.9ixz30jbn

If I typing into my shell 'tor' I get this:

Aug 31 21:01:29.871 [notice] Tor v0.2.8.6 running on Linux with Libevent 2.0.22-stable, OpenSSL 1.0.2h and Zlib 1.2.8.

Where is my error, or wich command is the right?

Answer 1

You've made no mistake. That output indicates that Tor launched, connected to the network and is running. You'll probably want to figure out how to daemonize it, or run it in the background (nohup tor &).

The line Opening Socks listener on 127.0.0.1:9050 tells you that it's SOCKS (proxy) port is listening on port 9050. This is the port you want applications like curl or wget to proxy through.

As shown in the article you linked, you just need to run curl using Tor's SOCKS port.

curl -s --socks5-hostname 127.0.0.1:9050 http://www.showmyip.gr

On RHEL/RHEL-clones, the tor package is available from a a torproject repository. After it's enabled you can install and start the tor service like this:

dnf install tor
systemctl start tor

Note that the tor service provides a SOCKS proxy for routing TCP traffic through the Onion network. Thus, each program whose TCP traffic you want to send through tor you have to configure such that is explicitly uses that proxy.

With curl, you can use the --proxy option like this:

curl --proxy socks5h://localhost:9050 'https://wtfismyip.com/yaml'

NB: The 'h' in socks5h means that also DNS requests made by curl go through the tor network.

For programs that don't support socks5h proxies natively - such as wget - you can use torsocks like this:

rm -f yaml
torsocks wget 'https://wtfismyip.com/yaml'
cat yaml

FWIW, Fedora, a kind of RHEL upstream distribution, has the tor package included in its main repository.
