Hello Pete, > When i am at home i would like the laptop to mount my NAS drive on > boot always connect via ETH cable never wiFi but out if i connect > via cable or wirless do not try to mount NAS drive , My thoughts > Would it be possible to script it so that it checks for an specific MAC > address before trying to mount the NAS as IP address would not work > lots of 192.168.x.x networks out there A very simple solution would use netcfg profiles for your home network and connect to the NAS server with the POST_UP= param[1]. This would make things easier for you because you will not have to connect to the NAS on every boot (since you said its a laptop and i assume you use it on other places than your home) and only connect to the netowk you desire, either by wireless or wired. You can also add the PRE_DOWN to disconnect of your mount safely before disconnecting the network. If you desire you can set the network to start on boot (by simply adding the profile name to your rc.conf) but this will make your boot a little slower if you're not on your home (like connecting to your NAS does).
