You are doing this from another computer that also runs X ?
I think your local DISPLAY variable must be correct on the computer you are SSH'ing from also. (but not sure if this is required)
Yes, sorry I did mean $DISPLAY

Running a browser from an SSH session

I have Googled this but can't seem to find anything that actually works for me. It would appear that I should "ssh -X [email protected]" and then if I type "echo DISPLAY" I should get something like localhost:1 but I get a blank string. When I try to start any graphical apps it says "cannot open displa...

Question about multiple LAN adapters

I have an extra LAN connection on a Pi using a USB/LAN adapter. How do I determine the order in which the LAN adapters will connect to the internet ? Is it the order they appear in the interfaces file ? [Edit} I should have explained. I have two different internet sources attached to these two LAN c...

Re: Setting up a Mac as a DHCP server

I assume you are planning on using a wired connection between the RPi and Mac, correct? I personally wouldn't bother with setting the Mac up this way for such a trival case, especially if it's not normally operating as a server. Configuring the Mac and RPi with fixed IP addresses is certainly simpl...

Re: Setting up a Mac as a DHCP server

One of the reasons I like mac and use it is because of the Internet sharing. You don't need a Internet connection. Simply go to Sharing in the Settings and check share Internet. I've tried doing that but it's not clear what to do next. I'm showing an ip address on my Mac of 169.254.16.57. Do I have...

In order to use it as eth1 you will have to set up entries for eth1 in /etc/network/interfaces. Copying the existing eth0 configuration should work.
Brilliant thanks, works a treat.

Anyone had any luck getting one of these to work. It doesn't appear on the wiki list of known to work adapters, but I just happen to have one kicking around. When I do an ifconfig I see an eth1 device, but it's not got an ip address.

That's an interesting approach, I'd never heard of PiNet until your post. I've had a quick skim through the user doc and it looks a real possibility. Would you happen to know if there is any significant performance hit loading the OS (and apps ?) across the network ?

How big is the set of devices? Do you have control of all of them? For something simple, you could set up a master repository (a directory with ssh shell access for some user) and set up a crontab that does rsync from that master on each of the devices at a frequency you decide. You could also use ...
