How can I (or my customers) access webmail, cPanel and WHM on port 80? I am behind a strict firewall?

We have built functionality into cPanel to use cpanel.domain.com and webmail.domain.com over port 80 so that you can still access cPanel and your webmail behind a proxy server. Simply replace domain.com with the name of your website.

This functionality can be turned on and off in the Tweak Settings menu of WHM. The specific setting is called 'Automatically create cpanel, webmail, webdisk and whm proxy subdomain DNS entries for new accounts. When this is initially enabled it will add appropriate proxy subdomain DNS entries to all existing accounts. (Use

Code: Select all

/scripts/proxydomains

to reconfigure the DNS entries manually)'

To enable proxydomains for the whole server:

Code: Select all

/scripts/proxydomains add

To enable for all domains on one user’s account:

Code: Select all

/scripts/proxydomains –user=<user> add

To enable for a single domain:

Code: Select all

/scripts/proxydomains –domain=<domain> add

From here, you can access the proxy at http://cpanel.domain.com (or webmail/whm, respectively), or access cPanel normally and let it detect whether you are behind a firewall.

THIS IS RELEASED IN PUBLIC DOMAIN, BUT I HOPE YOU WILL:
- Send me an email if you use this (specially if you are a host)
- Send me improvements if you make any
- Update this text if you change the script
- Don't change this text otherwise, specially I hope you will keep my
  email-address and the url

Installation instructions:
- Create subdomain "cpanel.yourdomain.com" (You'll probably need access to
  cPanel for this, so install it before you need it!)
- Download and unzip cPanelProxy.zip (if you haven't already)
- Upload the files to the subdomains directory, probably "public_html/cpanel"
  in FTP. Be sure to remember .htaccess!
  Needed files: cpanelproxy.php .htaccess php.ini

Install for webmail and whm:
- Repeat with "webmail" in stead of "cpanel" in subdomain and directory.
- Repeat with "whm" in stead of "cpanel" in subdomain and directory.

Auto Installer:
- A new feature on the website makes it easier to install cPanel Proxy, and
  you can even do it thru your firewall. All you need to do is to enter your
  cPanel login information, at the auto installer will take care of the rest.
  http://cpanelproxy.net/autoinstaller

Known problems:
- No https
- cPanel will say that you are logging in from "localhost". This may be
  considered a security problem by some people.

Other suggestions for improvement:
- Persistent sockets
- Adjust buffer-sizes (currently they are all 10240)
