Is there a way to change the IP address which is given by Tor from the terminal?

I have the Tor service, and I want to change the IP address which Tor gives me from the terminal. Or in other words: How do I request a new IP address from Tor on the command line?

For tor daemon running on Ubuntu, first try this:

killall -HUP tor

If that does not work, enable the control port in your torrc file.

Then, set a password for the control port with tor --hash-password password.

Open a telnet connection to the control port and issue the NEWNYM command:

printf 'AUTHENTICATE "password"\r\nSIGNAL NEWNYM\r\n' | nc 127.0.0.1 9051

You can simply type or insert in your bash script:

service tor reload
  • I needed sudo, but this worked. – Brian Z Aug 15 '16 at 20:27
  • To me this is actually a better answer then the one @mchid gave. The reload command will trigger the running tor executable to reload its configuration and setup a new circuit (and thus get new IP). The other answer will kill the running executable and restart it. This might take longer and cause other services depening on tor's proxy to be there to fail. – Alex Sep 16 '16 at 16:48
  • I don't know why others suggested such a complicated solution while this simple line can solve the problem – Mostafa Ahangarha Jun 17 '17 at 10:31

    @MostafaAhangarha Because this doesn't work for multiple tor instances – MewX Dec 10 '17 at 1:46

You can set up a control port and use the python script

from stem import Signal
from stem.control import Controller

with Controller.from_port(port = 9051) as controller:
    controller.authenticate()
    controller.signal(Signal.NEWNYM)
  • Do you know how to wait until the new ip is set? – silgon Sep 4 '18 at 10:42

Method 1: HUP

Mentioned at Change IP address which is given by Tor using the terminal but here go a few more details:

sudo killall -HUP tor

Then check that your IP has changed with:

curl --socks5 127.0.0.1:9050 http://checkip.amazonaws.com/

Tested in Ubuntu 17.10 with sudo apt-get install tor version 1.6.0-5.

sudo is needed since the process is started by root by default.

What an HUP signal does exactly to the Tor daemon is documented at: https://gitweb.torproject.org/torspec.git/tree/control-spec.txt?id=03aaace9bd9459b0d4bf22a75012acf39d07bcec#n394 and is equivalent to sending some command through the command port.

Browser Bundle 5.0.5 is not affected by this, only daemon ports like the default 9050, which is not used by the TBB. For that use case see: https://tor.stackexchange.com/questions/1071/how-can-a-new-circuit-happen-without-closing-all-tabs

If you are deploying an army of Tor IPs as mentioned here you can selectively send:

kill -HUP $PID

Method 2: control port

Mentioned by kat:

(echo authenticate '""'; echo signal newnym; echo quit) | nc localhost 9051

but for that to work on Ubuntu 17.10 you must first:

  • enable the control port by uncommenting:

    ControlPort 9051
    

    from /etc/tor/torrc

  • Set the empty password, otherwise it gives 515 Authentication failed: Wrong length on authentication cookie.. First run:

    tor --hash-password ''
    

    This outputs something like:

    16:D14CC89AD7848B8C60093105E8284A2D3AB2CF3C20D95FECA0848CFAD2
    

    Now on /etc/tor/torrc update the line:

    HashedControlPassword 16:D14CC89AD7848B8C60093105E8284A2D3AB2CF3C20D95FECA0848CFAD2
    
  • Restart Tor:

    sudo service tor restart
    

Bonus: how to check that your IP changed

curl --socks5 127.0.0.1:9050 http://checkip.amazonaws.com/
