Billion BIPAC 7300G

These things have a couple of oddities worth watching for.

One of them is that adding a port-forwarding rule (“Virtual Server”) doesn’t automatically grant any access through the firewall, you have to add a separate firewall item to allow the traffic that you’ve just enabled.

The next thing is that saving to Flash doesn’t always work across the board, so do your saves, reset the modem, & test it. One place this bit me was that setting up port-forwarding rules, then firewalling rules, then saving the lot resulted in only the firewalling rules being saved.

The next thing is also port-forwarding: the forwarding won’t change the port, so a connection to 1.2.3.4:22 might be forwarded to 192.168.1.250 on the LAN, but always to port 22. So if you want to do my typical security trick of putting things like SSH services on odd ports, this has to be done on the machines themselves as well as adding a port-forwarding rule & a firewall rule to the ADSL router.

A final thing is that their PDF manual doesn’t quite match up with the real-life hardware. The differences are relatively minor, but they are there & need to be adjusted for.

Discovering all of this at a range of 4000 km was a bit testing, & I’m very glad that I had a patient, steady Jane as a relay between the ’phone & the keyboard at the other end, & that we use Southern Cross Telco as a telephone provider. They’re very steady providers, & have some useful long-term long-distance features to their plans, which allowed me to rattle on & experiment for nearly an hour across Australia for less than a gold coin.

Oh, you can actually change the inside port — by keying in a vanilla-flavoured Virtual Server and then coming back and Editing it.

Meanwhile, the only way you can get this sucker to P/F to port 80 is by renumbering its internal web service (e.g. to port 88) first.

On my 7300A, HTTP port forwarding didn't work on port 80 until I moved the router's web interface away from 80. i.e. move the web GUI to something like 8080, then you can use port 80 for port forwarding.

I changed the internal router port to 88 so the port 80 was free for my web server! In this way I forwarded succefully to port 80 on my web server! Thanks!

new life for an old (FTX) PSU, improved life for one human

the LEDs on this 5m strip happen to emit light centred on a red that does unexpectedly helpful things to (and surprisingly deeply within) a human routinely exposed to it. it has been soldered to a Molex connector, plugged into a TFX power supply from a (retired: the MoBo is cactus) Small Form Factor PC, the assorted PSU connectors (and loose end from the strip) have been taped over. the LED strip cost $10.24 including postage, the rest cost $0, the PSU is running at 12½% of capacity, consumes less power than a laptop plug-pack despite running a fan. trial runs begin today.

every-application-is-part-of-a-toolkit at work

I have a LibreOffice Impress slideshow that I wish to turn into a narrated video. 1. export the slideshow as PNG images (if that is partially broken — as at now — at higher resolutions, Export Directly as PDF then use ‘pdftoppm’ (from the poppler-utils package) to do the same). 2. write a small C program (63 lines including comments) to display those images one at a time, writing a config file entry for Imagination (default transition: ‘cross fade’) based on when the image-viewer application (‘display,’ from the GraphicsMagick suite) is closed on each one; run that, read each image aloud, then close each image in turn. 3. run ‘Imagination’ over the config file to produce a silent MP4 video with the correct timings. 4. run ‘Audacity’ to record speech while using ‘SMPlayer’ to display the silent video, then export that recording as a WAV file. 4a. optionally, use ‘TiMIDIty’ to convert a non-copyright-encumbered MIDI tune to WAV, then import that and blend it with the speech (as a quiet b...

boundaries

pushing the actual boundaries of the physical (not extremes, the boundaries themselves) can often remove barriers not otherwise perceived. one can then often resolve an issue itself, rather than merely stonewalling at the physical consequences of the issue.
