[feature request] add special hosts for gateway and dns server

[Peter Rullmann]

Please add two options to enable special hosts to monitor: the standard gateway and the dns-server.
These hosts are interesting for quick diagnosis if the internet connection is down. But their address is dependant on the network, the computer is connected to, so they can't be added to the Link Monitor Prefs Hosts list at the moment.
The standard gateway ip address could be obtained eg. by running "route -n | egrep ^0.0.0.0 | cut -b 17-31"
The first dns-server ip address could be obtained eg. by running "grep ^nameserver /etc/resolv.conf | head -n 1 | cut -b 12-"
But I am sure, there are more elegant ways to obtain these IPs.

Thanks for reviving the Link Monitor Applet idea!

Hi Peter,

at least for the current gateway, you can install libnss-gw-name and configure l-m-a to ping gateway.localhost – that’s what I’m doing. And the same package could provide names for the DNS servers, if someone adds support for that.

Gruß,
Joachim
