I have the Tor service, and I want to use the terminal to change the IP address which Tor gives me. 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 9051



You can simply type or insert in your bash script:

service tor reload
  • I needed sudo, but this worked.

  • 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.

  • I don't know why others suggested such a complicated solution while this simple line can solve the problem Jun 17, 2017 at 10:31

    @MostafaAhangarha Because this doesn't work for multiple tor instances

  • @Alex If you just use the second method and issue the NEWNYM command, it will stay running and you will get a new IP because it will switch to clean circuits.

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 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:


    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 http://checkip.amazonaws.com/

  • Such complicated solutions for such a simple function (get new circuit). I don't trust tor at all anymore. I think it is full of bugs and glitches to make us expose ourselves

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:

    Do you know how to wait until the new ip is set?

A one-liner that makes tor use a different ip address:

systemctl show -p MainPID tor | cut -d= -f2 | xargs sudo kill -HUP
