Sftp with no ssh shell

Simple question, if I change the /bash to nologin or similar in passed for a user, will that affect the sftp connection as it would an ssh login?

Copying kore remote configs to multiple devices

Running a few OSMC rpi units in the house and have my Kore app on my Android phone configured with all the location names, user/pass, etc. Is there a way to copy these configurations to the other phones and tablets or is there a better remote app I can use and do this?

Re: Alarm System using existing DSC wiring

I know this is an older thread, but I just stumbled on it. I am an alarm installer, specifically DSC products.

Re: Hook up professional wi-fi survaillance cameras with a Raspberry Pi

What brand of camera and actual NVR are you working with? Most respectable brands have direct port forwarding options which would not require the use of their cloud software of DDNS. If the equipment used is proper pro grade, it would have ONVIF capability which means you can use pretty much any NVR...

Probably a dumb slip up on my front. Running a RPI with DNSMASQ. IP addresses (both eth0 and eth1) are set in rc.local statically.

Since electronic components don't wear out unless they're maltreated, I wouldn't replace it until you've proved it faulty.
