Basic Network Tools

This is an intro to some of the diagnostic tools that other documentation will refer to.

Setting a static IP

This is useful for debugging routers, and specific links to existing static IPs.

Ubuntu

On Ubuntu, you can do this by going to control center -> network connections, selecting the current ethernet connection, clicking the gear, then going to the IPv4 settings tab.

1. Under Method, change Automatic (DHCP) to Manual

2. Under Addresses, click add. You want to add an address within the range of the router you are trying to interface with (see Internet Uplink and LAN). The netmask is the number of bits, starting from the left, that stay fixed:

   Address	Netmask	Gateway
   192.168.102.5	16	192.168.102.1

3. Where it says DNS servers, put either 216.218.196.2 (HE's DNS server) or8.8.8.8 (Google's public DNS server).
