Frequently asked questions
Regretfully, there is some general and specific software we cannot permit on our customers' webhotels, for the sake of resource usage, security and service stability.
Webhotel is a service for websites, and is not designed for handling other types of services.
Here are some of the guiding principles for permissible and non-permissible software.
- OK: software executing briefly via PHP or CGI on the webhotel, or which supports webhotel maintenance on the login server
- Not OK: software with too long execution time, which uses too much memory (RAM/swap), CPU, intensive disk usage, and/or intensive database usage
- Not OK: software posing a security risk, sending of unsolicited email (spam), software suited for damaging third parties, or illegal software
About resource limits
Our PHP configuration has default limits that must not be exceeded, and software exceeding these limits may be forcably terminated and deactivated.
CGI software shall adhere to the same limits.
Even if software does not exceed the specific limits, it may still use too much resources, overloading the webserver. Your webpages will no longer work, and neither will any other webpages on the same webserver. In such case, we will temporarily deactivate the webhotel causing the problems.
The webservers are behind a firewall, which prevents software not using HTTP.
Some types of software is not permitted, no matter what the cause is, regardless of whether it is run on a webserver or login.domeneshop.no. The following list contains examples, and is not exhaustive:
- Bittorrent clients or servers, or other similar distribution services
- Chat or IRC robots/proxies
- DoS/DDoS tools
- File management scripts in PHP or CGI (regardless of language)
- Firewall circumvention, or attempts to circumvent
- Insecure software (known security vulnerabilities)
- Obfuscated/encrypted software that cannot be automatically verified as secure/original
- Performance tests for max capacity of our servers/computers/lines
- Port scanners
- Proxies (e.g. for anonymization)
- Remote shell via web
- Root kits
- Scam software (e.g. phishing)
- Spam software
- Spy software
- Video transcoders
- Viruses, trojans, etc.
