Re: Using two wlan iterfaces, one as client, one as access p

Normally you should at least get wlan0 to connect to your router. Maybe wlan0 is the Edimax thinggy now? You are correct, some pieces of the puzzle are missing: - You want to setup hostapd to create an Access Point, - Then if you want to allow the machines behind the hostapd AP to access the Interne...

Re: VPN security

A password is a secret. When it is not secret, it's worth nothing. Attacks on VPN servers can take place on the client. Usually the client is the weak point. If you leave ssh accessible via the VPN, then the server is open to root attack in < 1 second. Plus the possibility of local attack on the ser...

Re: Using two wlan iterfaces, one as client, one as access p

Welcome. The howto for client/AP flip-flop you're linking is 3.5 years old. It was not written for the version of Raspbian that runs on Pi 3. For the 2-interfaces case, you'll get wlan0 and wlan1 on your Pi, right? Then read on any guide that talks about routing between eth0 and wlan0 and just read ...

Re: dhcpcd.service takes longer time on Lite

Do you have a file named /etc/default/networking in Lite?
If so, I suspect it says "CONFIGURE_INTERFACES=yes", and setting it to "no" would make boot times equal. But I don't know if you'd land at the login prompt with a working network or not.

Re: Internet connectivity issues

Why are you using a public IP network for wlan0? Can't you use 192.168.1.0/24 or something like that? These resolv.conf files are wrong from start to finish. Once you've used a proper private LAN config if this continues a reinstall of resolvconf might be in order... - There is no "=" characters all...

It won't transcode with srt subtitles, as long as the client supports displaying srts.

Re: Ubuntu Snappy Core for Pi 3

Simple question, why do you require 64 bit addressing?
For me, the reliability of ubuntu 32bit 16.04 on Pi3 is more of a subject. (speaking of the "regular" server OS)

Re: Ping watchdog over to the Raspberry (setting watchdog.co

With the watchdog in Pi 3 the slowest ping loop you can go to is about 10 seconds. That's very fast IMHO, so I have looked for another way to do that. I recently posted my setup which pings every minute and reboots after 30 minutes of consecutive ping failure. https://www.raspberrypi.org/forums/view...
