If your computer is connected to a fixed network (i.e. an Ethernet or equivalent connection— not a dialup/PPP connection) which is administered by somebody else, you should ask your network’s system administrator for this information:
• Your host name (you may be able to decide this on your own).
• Your domain name.
• Your computer’s IP address.
• The netmask to use with your network.
• The IP address of the default gateway system you should route to, if your network has a gateway.
• The system on your network that you should use as a DNS (Domain Name Service) server.
• If the system is connected to a VLAN trunk port the VLAN Id is needed.
To display the VLAN configuration settings, the debian-installer’s debconf priority needs to be switched from high (default) to medium.
If the network you are connected to uses DHCP (Dynamic Host Configuration Protocol) for configur- ing network settings, you don’t need this information because the DHCP server will provide it directly to your computer during the installation process.
If you have internet access via DSL or cable modem (i.e. over a cable tv network) and have a router (often provided preconfigured by your phone or catv provider) which handles your network connec- tivity, DHCP is usually available by default.
If you use a WLAN/WiFi network, you should find out:
• The ESSID (“network name”) of your wireless network.
• The WEP or WPA/WPA2 security key to access the network (if applicable).
