Hosts file with port?

  • 772

I know you can't put a port in /etc/hosts, so how can I achieve the equivalent of:

127.0.0.1     https://website.com:4433

For WordPress, I need CURL to go to 127.0.0.1 on port 4433. As it's wordpress and not a script I made, I can't change that.

    I managed to find the iptables rule to fix my issue:

    iptables -A OUTPUT -d 127.0.0.1/32 -p tcp -j DNAT --to-destination 127.0.0.1:4433

  2. Add a line into your /etc/hosts:

    127.0.0.1      website.com

    then configure your program (whatever it is) to listen on 4433 at 127.0.0.1.

    And you're done.

    Example:

    echo hi | nc -lt 127.0.0.1 4433

    now open website.com:4433 and you should see a "hi".

    to fix the problem you mentioned in the comments you can use socat:

    socat tcp-listen:4433,reuseaddr,fork tcp:localhost:xx

    with the above command, socat will listen on 4433 and whenever a request came in in will forward it to the xx, so change the xx with the real port where your program is listening to.

  3. If you use the Chrome web browser, they have a URL aliasing app. It's called URL Alias. Just load it and define a web site. In the definition, you can add the full URL with port designation.
