Systems accessible by name within LAN

  • 772

What protocol is used to reach computers by typing their names? For instance ping laptopone essentially finds the IP of the device and then pings it.

I used to have an AVM FritzBox 6360 as router / DHCP server within my network. Every device was reachable by its network name. Now I changed to a new box called ConnectBox and only half of my systems remain reachable:

myuser@systemone:~$ ping laptopone
ping: laptopone: Name or service not known

I assume that the AVM took the job of associating the DNS calls, basically associating the computer name to an IP address. The ConnectBox doesn't seem to do that job which means only some systems have the needed service running as daemon or process.

What type of service is needed on a system to enable it to answer to its name when there are network calls like ping or ssh?

networking

    Solved by recognizing that the mentioned router doesn't have any DNS service. Building an own DNS server with Bind and propagating it using DHCP might be the solution. Thanks to @ByteCommander and @dobey.
