RISC OS RPi wireless via Raspian?

I have a Pi3 running Raspian strapped¹ to an ARMv7 Pi2 running RISC OS. They connect to my HD monitor via a cheap HDMI switch² so that, when VNC fails due to excessive scrolling (as it often does!), I can use Raspian directly with a wireless keyboard and a plugged-in mouse, reconnecting via VNC once the required page is set-up. This is for stuff like internet banking and other sites requiring functional JS. It allows me to have my bank account data and a spreadsheet on the same RISC OS screen simultaneously. As the Pi3 has inbuilt 802.11n wireless, it can connect wirelessly to the router (I use fixed IP addresses for my own convenience). My query is: Is there any simple way I can make the now-redundant/spare RJ45 network socket on the Pi3 act as a LAN connector for the RISC OS Pi2 by patching them together? I am anticipating that this will require some sort of (network?) server on the Linux side, but what, and does it exist? Or is there something possible with the Routing part of the RISC OS internet set-up that we were always advised (by Druck!³) not to fiddle with? If it is possible, it would provide a neat and compact solution to the problem of running RISC OS wirelessly and having access to a JS browser! ¹more elastic-banded, actually! |

You can totally do this. You may need a crossover cable though, rather than a straight network. Most likely you will need to edit iptables, or whatever firewall linux uses these days, and possibly need to configure routing if it isn’t bridged. Bridging might be an easier option, but it’s not a common configuration so documentation/tutorials would be light. I think using static IPs on the crossover would be the simplest, and follow a tutorial on setting up a linux router. Consider the WiFi the WAN, and ethernet the LAN. Unfortunately I am an OpenBSD guy, so I can’t hold your hand on this. |

Encouraging! But where’s the Raspian guy! |

This is what RComp’s PiFi and RISCOSbits Wispy do to provide WiFi to RISC OS. Wispy (available Real Soon Now) also has the option to run Firefox and LibreOffice in a RISC OS window. |

Unless I’ve got a hold of the wrong end of the stick, I think: |

A smart ass (hi!) could load up SwiftJPEG and show you a screenshot……. :-p |

According to the RISCOSbits website as of today, Wispy is still at the point of “Release Imminent” and the prgrammer has ‘run away’. And, according to the RISCOS London show website, RISCOSbits will be at the show, but there is no mention of Wispy being exhibited. :-( |

Or been taken away? “The original programmer is no longer able to contribute to the project” Unavailability could be due to a number of different circumstances! It looks as though the device does exactly what I put forward in the first posting of this topic, but using a less-expensive but arguably more-arcane device, the Orange Pi Zero 512MB SBC. It will also use RDP rather than VNC, the latter proving a bit flakey for this purpose, thus making my emergency HDMI switch redundant. I feel an e-mail coming on! |
