    The reason I use x11vnc is that it connects to the existing graphical session. Most other vnc servers will spawn an entirely new graphical session. While that is super cool, I don’t want that feature. This is for remote support, where I want the user and the supporter to share the same session. I use…

    The new versions of OpenWRT (18 and newer) have the ability to add vlan interfaces directly from LuCI (web gui). You can now skip the manual editing of the /etc/config/network file.

    I have many open-mesh OM1P units laying around from failed wireless projects. Needless to say I’m not a big fan of open-mesh and have some other projects in mind for this hardware. It was a painful process but well worth it. Now I have nice little OpenWRT units for any hacking pleasure. I have made…

    In this scenario we will be implementing a openWRT as a wireless access point only. One wireless essid will be LAN accessible and the other will be segregated from the LAN but able to access the WAN. The openWRT in this example will not be the gateway to the network. Another device is the gateway…

    UPDATE: The easiest way to do this is through the web interface (LuCI). System -> Administration -> SSH-Keys. Paste your public key (~/.ssh/id_rsa.pub) and click “Add key” I’ve been using so many openwrt devices lately I wanted to setup my public ssh key on each device so I can auto login. Also, I can setup…

Create the following batch script, name it something like ovpnConnect.bat, and right click to “Run as Administrator”. This does require the openvpn gui from openvpn.net to…
