Instructions for use
See the instructions below for connecting various devices to the network and other situations.
Virus protection and problem situations
You can use F-Secure’s free Online Scanner software for immediate virus protection. In more difficult situations, in which the virus hides away from the active operating system or when the computer’s operating system no longer starts, you can try using F-Secure's Rescue CD. Other free antivirus software is also available, such as e.g. Avast Antivirus. It is also worth checking out Microsoft’s instructions concerning virus and malware protection in Microsoft's Windows environment.
Details concerning online services:
|Sending email||smtp.lut.fi, smtp.lnet.fi|
|Network time protocol (NTP)||ntp1.funet.fi, fi.pool.ntp.org|
Wireless routers and connecting several devices to the network
The easiest and best way to connect several devices to Lnet is to use a suitable wireless base station or router. The router will transmit the traffic of your devices to the Lnet network and at the same time the devices connected to it will be seen by Lnet as one network device (so-called NAT function). In this way, the limited number of IP addresses on the network will not cause connection problems. The router also prevents other network users from seeing any files shared between your devices, and shared printers etc. between your computers.
Wireless networks must be encrypted for personal privacy protection since an unencrypted network is easy for third parties to use. The holder of the connection, i.e. the tenant of the apartment is responsible for the traffic sent and received over the connection. The recommended encryption method is WPA2-PSK or the newer WPA3.
Please note that sharing the network connection to third parties is prohibited in the operating guidelines, and connecting the Lnet connection to systems intended for sharing network connections is also prohibited. Separate and more detailed instructions on the selection and use of wireless base stations are available.
Connecting game consoles
The same rules apply to connecting a game console to the Lnet network as in case of computers. Set the DHCP function on and connect the device directly to Lnet, or preferably to your own router. Challenges may arise when trying to connect older game consoles to the Lnet network.
Filtering traffic and offering services from your own computer
The firewall between Lnet and the Internet mainly filter all incoming traffic, except for the university’s traffic from where incoming traffic is permitted. In principle, outgoing traffic is not restricted, excluding the following exceptions:
- Sending email elsewhere than to Lnet’s and LUT’s email servers (smtp.lnet.fi and smtp.lut.fi) is prevented in order to reduce the risk of spam.
- The traffic of peer-to-peer software (p2p) has been prevented due to the large amounts of traffic they cause. Almost all traffic transmitted via them is the illegal distribution of material that is subject to the copyrights of movies, music, etc.
Although Lnet has not put any restrictions in place, not all services provided by the university can be accessed via Lnet. The home directory at the university can be accessed via the portti.lut.fi service. As of now, the amount of traffic is not limited, but interventions to the amount of traffic can be made in exceptional situations.
Upon request, you can obtain an open SSH or HTTP port for a a computer connected to Lnet, as well as a fixed IP address for this purpose. Justified requests are submitted to administration.
Apartments’ switch panels at LOAS Timppa
At LOAS’ Timppa building cabling has been implemented slightly differently than elsewhere. There is one cable in the fuse cabinet located in the hallway of the apartment, which can be connected to a chosen socket within the apartment from the panel in the cabinet. The RKT B1-connector is the cable coming into the apartment and items 1-4 refer to the sockets in the apartment. In order to use more than one sockets, you can use a standard switch or preferably a router. To establish your own WLAN network, you will also need a router as in the case of other properties.
