Re: SD Image Creation/Backup/Compression

Assuming you don't want to do this with the card running the system, you could do something like this (not a complete recipe, but not too hard to work out if you are fairly familiar with Linux): Thanks, this is exactly the problem...

I use a lot of PI's which have some very specific software on them that has to be installed and compiled and tweaked.. its not a very scriptable process via BASH or anything else really.

Re: KVM Switches Pi's and other

I'm using an Iogear 4-port Miniview. It's an HDMI/USB KVM. Link? The way to handle your monitor with DVI input is to use HDMI cables between the Pis and the KVM and then use your HDMI to DVI cable on the shared output to the monitor. That was/is sort of the plan, but I expect issues with the KVM an...

Re: RasPi won't connec to one server???

Did you checked if there is anything unexpected in your system log files related to that Pi’s network connection? E.g. “/var/log/messages” and “/var/log/syslog “ in Raspbian. I think the log files can be helpful. I recently solved a strange wifi lost connection issue in that way. I'll watch it the ...
