Network access and remote access
How do students of the RPTU in Kaiserslautern come to Internet access ...?
- From the login servers of SCI or RHRZ you have access to the Internet.
- A W-LAN is installed on the RPTU campus in Kaiserslautern, which students can use access the Internet with your private computer (notebook with W-LAN adapter) To do so, you will need an RHRZ account (for further information, see here).
- Students who live in residence halls in Kaiserslautern can use the free Internet connection offered there with their private computer.
- For a private internet access in your apartment you usually have to find a provider
yourself and also pay the costs yourself. When looking for an apartment,
you may want to consider whether your landlord offers you a DSL connection or whether a commercial W-LAN network is available.
In order to access RPTU in Kaiserslautern's network services from the Internet, which are only accessible from the RPTU network, you can also register from outside via the VPN and thus temporarily obtain a RPTU network address. You will need an RHRZ account for this purpose.
Note: Do not try to connect directly to the physical TU network in any case!
Such access can cause considerable damage and may be punished as computer sabotage.
This is especially true for the networks in the terminal rooms!
(The networks are monitored for external access and you will not get Internet access from the SCI terminal networks anyway).
