With Jessie I cannot access any of the stream outputs or the Motion control page at 8080: from a remote computer. I have had no problems previously with Wheezy. I therefore tried Motion with the latest Wheezy version after failing with Jessie and it works fine.
I set a static address for both Jessie and Wheezy and that works fine on both.
I simply have a router with a wired connection to the Raspberry Pi whilst I have a wireless connection to the remote computer. As I say it works fine with Wheezy. To access the pi from the web browser I use a local address 192.168.0.(piaddress):8080 Can anyone else confirm this? or have you got it working.
