I like Debian a lot and find great joy in keeping old computers around as workstations, proxy servers, file servers and the like. The proxy, for example, just got upgraded from a 486 with 20 MB of RAM to a Pentium Pro with amazing 128 MB of RAM. Linux is perfect for these purposes.

Most of my hardware was given away by friends or taken from junk containers. While I think that electronics freeganism is nice and reduces waste, the greatest benefit is that it's very educational.

Also: Electronics hacker since the age of 5. MSc in Electrical Engineering / Communications Techonogy. Hacking analog and power electronics for industrial robots as a job.

comment 10base2 (a.k.a. thinnet) over TV coax (wrong impedance) - will it work?
Excellent answer, you link to some of the sources I have read and considered trying since I first posted the question. As far as the DIY circuits go, I am pretty sure it would have to be the resistive divider, because the others (using L and C), while lossless, would work at a specific frequency only. Also, I am happy to announce that the dirty hack of 10base2 over 75 Ohm coax (without impedance matching networks) works well enough, and even shows a fairly good eye pattern on the oscilloscope. I still have to compare the current setup to to using a resistive matching network...

comment I lose access to my router's config interface once I set it to “Access Point”
The setup is a bit different from your guess. I have a DSL modem, a router (linux box), and am trying to connect the wifi box to my internal home network (192.168.1.0/24). I agree it's best to let the linux box be the DHCP server, and I thank you for the background info. But back to the thing that got me curios in the first place: Any chance that the wifi box doesn't change its IP address when being reconfigured as AP, but loses it alltogether, becoming completely transparent - the same way a simple and cheap 5- or 8-port wired ethernet switch never has an own IP, and never had one by design?

Thanks for explaining the right terminology.

@RenjuChandranchingath Accessing the router after setting it up as an access point works neither using wifi nor using a cable connected to one of the four LAN ports.

comment Extend local network using a DSL wireless modem as an access point
If I understand your answer correctly, it is OK to use multiple APs on one subnet, and assign an identical SSID to any of their WiFis? A WiFi client will not become confused when it "sees" more than one AP and tries to negotiate a connection with one or the other?

comment Launching firefox on remote server causes local firefox to open the page instead
If I read ssh's man page right, setting -X just enables X forwarding via ssh on a system that doesn't have X forwarding enabled in the configuration files, i.e. ForwardX11 yes and ForwardX11Trusted yes in /etc/ssh/ssh_config If anyone knows details about the internal X Window system communication you mention, I would be very interested in knowing them, because it may have to do with a problem I'm trying to find out about: unix.stackexchange.com/questions/64335/…
