Having trouble with Putty? Here is a way to negate it.
We had issues getting our computer to communicate with the GS even though it was connected via Ethernet. So we ran some software updates, much needed updates at that, and then began playing with the internet protocols on the GSLaptop.
We set the IP on the computer (internet proto v4) to 192.168.1.101 (an ip within the range of our ground station modem) then set the subnet mask 255.255.255.0 (same for everyone) then set a default gateway to 192.168.1.100 (also within the ip range)
we then plugged in a monitor and keyboard directly into the Pi payload and started the stream directly within the pi; we are still working on the start up script to run stream.sh with a turn of the key. The pi then pushed the video out to our GS and we were able to view it in the VCL media player. We tested this in the field and found that once started, the keyboard and monitor could be unplugged and the stream would continue(this is a great last resort.) Additionally the best part is that even if the signal is temporarily lost, the VLC media player would automatically reestablish the connection! If the connect was lost for more than 5 minutes, simply restarting VLC would reestablish connection.
EDIT: leviw posted a working "turn key and stream" start up script Here! and we got it running today on ours. Great stuff!
Just a quick note about updates, putty, and McAfee: Certain Windows Updates will change which program controls the firewall. Windows Firewall will block putty and putty will time out whenever trying to ssh to rfd or ubiquity payloads. McAfee will not block putty. If you ever do an update and then you can't connect via putty, connection will time out, it may be because Windows Firewall. You can go in and add an exception to Windows Firewall for putty so putty is not blocked. My personal recommendation is to add the exception for putty in Windows Firewall so that any future updates will not disable putty from connecting no matter what program is controlling the firewall. Some teams have noticed a performance increase by disabling McAfee on the GS laptop but our experience showed no change whether McAfee was enabled or disabled. If you do disable McAfee you will have to add an exception for putty in Windows Firewall.
