Docker Hub

RUG WEBHOSTING

  • Kubernetes domain hosting
  • 5+ GB website space ( fair use policy )
  • PHP support (Linux/Apache variant)
  • ASP support (Windows/IIS variant)
  • All container based services.

The following options are available at an extra charge:

  • expansion of web space (in consultation with CIT)
  • e-mail addresses
  • domain registration (.nl, .com, .org, .eu, etc.).

Since 2017 every new hosting domain is automatically a docker environment.
There's still a active connection between the old shared environment and the new one.

HTTPS

The whole webhosting environment is behind several loadbalancers, force ssl does not work out of the box.
Because the internal communication between the loadbalancers (lb) and webservers are plain http.

If you force a website without the correct headers, the application will stay in a loop and fail.
The answer is simple , the webserver doesn't know that the request is secure! only the loadbalancer knows.

If we do a htaccess override, actually were telling the webserver , redirect once, if the Header HTTP:X-SSL-Enabled is true, don't do anything! otherwise redirect to https.

Examples

standard

client http (80) <-> http (80) -> http (80) -> website (80)

or both

client https (443) <--> (443) -> http (80) -> website(80)

force https

client http (80) <-> force redirect https (443) -> http (80) -> website (80)

htaccess Override

	# auto redirect to ssl, only for webhosting.rug.nl domains or with own certificates
	<IfModule mod_rewrite.c>
	RewriteEngine On
	RequestHeader set HTTP:X-SSL-Enabled "true"
	RewriteCond %{HTTP:X-SSL-Enabled} !true
	RewriteRule (.*) https://domain.webhosting.rug.nl/$1 [R,L]
	</IfModule>


wordpress https

Add the following to the wp-config.php

if (strpos($_SERVER['HTTP_X_FORWARDED_PROTO'], 'X-SSL-Enabled') != 'true') {
       $_SERVER['HTTPS']='on';
}

If you get mixed content warnings, in the default theme.
edit the file : wp-content/themes/twentyseventeen/assets/images/svg-icons.svg
and replace http to https

old  xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
new  xmlns="https://www.w3.org/2000/svg" xmlns:xlink="https://www.w3.org/1999/xlink">



SSH

SSH provides a secure channel over an unsecured network in a client-server architecture, connecting an SSH client application with an SSH server.
Common applications include remote command-line login and remote command execution, but any network service can be secured with SSH.

Example Connection

ssh f-number@ssh.webhosting.rug.nl

Example Tunnel

ssh -L 8080:IP:80 f-number@ssh.webhosting.rug.nl -N 1

WEB
This only works with Two Factor Authentication

https://ssh.webhosting.rug.nl

Two factor auth

Put two files inside you're homedir/.ssh folder
mobile_number and email_address

$ cat ~/.ssh/mobile_number
0612345678

$ cat ~/.ssh/email_address
email@rug.nl
