Re: Use Raspberry as WLAN for plex Server

I suppose the Pi is connected via wifi too? The best solution is to add an USB adapter to the Pi and add a bridged access point (hostapd) on the Pi. When the router fails this AP will still work, name resolution will continue working if you're using ".local" (mDNS). Or you can remove DHCP and DNS ta...

Re: Use Raspberry as WLAN for plex Server

Considering Plex server loves its SSO hence Internet access, and Chromecast too as I understand, I'm not sure the scenario works when disconnected from the Internet. It is possible to run an access point and Plex on the same machine. Of course it will be much easier if the Pi is normally connected b...

Re: WiFi stopped working

Re: Configuring iptables on Raspberry pi openvpn-server

You don't need another firewall unless you do not trust your router upstream, or you do not trust the users within the LAN. As to iptables configuration, there is nothing special to Pi. Raspbian has a rather relax firewall config by default with most (all?) policies (=default rule) set to ACCEPT on ...

If you're using Stretch, that file makes dhcpcd's life a tragedy. And as I said systemd is incompatible with ifupdown, certainly when it comes to rootfs on the network. You don't need systemd networking, just use dhcpcd as provided with Raspbian Stretch. You need to add nothing to dhcpcd.conf to mak...

Re: nfsroot shutdown hangs

Are you using /etc/network/interfaces?
Makes all sort of things go bad on Stretch (or Jessie IIRC) because systemd is not designed to work with it. It tries to support it but fundamentally these are incompatible.

So now it works manually but not automatically by openvpn?

If the openvpn daemon downgrades to nobody, try co...

Ethernet got subnet mask: 255.255.0.0 and Wifi got 255.254.0.0. I need the vnc connection to log in to the wifi every day.

Thank you! No the blank lines werent in my config. I wrote all without a blank line.
If you did that (what is posted in your first message now) this is still not correct. Separate the interface blocks with a blank line. See what I posted.

Use bbcode [code]...[/ code] when posting config files and machine console input/output traces. If the blank lines between the "interface" and "metric" keywords are actually in your config file, that doesn't work. Dhcpcd syntax mandates that some specific keywords, such as "interface", open a block ...

Re: Static Routing with OpenVPN

Make the tun appear on the Pi, and routing to 10.8.0.0 should start working.
No idea why it is not there. Maybe you should specify "tun0" in the conf instead of "tun", or conversely.
The client startup log should be enlightening. Add "verb 3" to your config. Above 3 is very verbose.
