OpenWRT on a Netgear DM200 ADSL Modem


Another bit of craptacular consumer tech gets the boot.

Ever since picking up a new DSL modem a ways back I'd been wanting to get OpenWRT up and running on it. That process turned out to be ... involved. Though with a bit of path-smoothing it could have gone far better.

The major pitfalls encountered were:
  • Determining the proper flashing method for installing the OpenWRT firmware. Which affects the next point:
  • Determining which OpenWRT firmware to install.
  • Determining how to recover from failed attempts and revert to Netgear's OEM firmware.
  • Properly configuring the WAN DSL interface.
  • Having the appropriate documentation available whilst offline during various experiments.
OpenWRT's documentation is excellent -- far better in detail, substance, and quantity than Netgear's DM200 offerings... show more

#throwback meiner achten @re_publica: „Wir sind nicht wütend genug. Steht auf!“, so brachte es @saschalobo in seinem Vortrag #realitätsschock während der #rp19 auf den Punkt. Auch mit seiner These: "Die Probleme des 21. Jahrhunderts sind nicht mit den Instrumenten des 20. Jahrhunderts lösbar." traf er für mich den Nagel auf den Kopf. Ein Highlight der #republica. Schaut euch seine Wutrede am besten auf YouTube an, wenn ihr #saschalobo verpasst habt. 👏🤓🤞 #FridaysForFuture #urheberrechtsreform #europawahl2019 #plastikmüll #filterblase #CO2Steuer #digitalisierung #digitaletransformation #berlin #entrepreneurlifestyle #entrepreneur #netzwerken #klassentreffen #networking #digitalconference #conference #konferenz #tldr

Great essay on network behaviour.


 

Article: Network Redirections in Bash.


by Anmol Sarma - software developer from Bengaluru ( #India ).

Preview/extract:

[...] it sends a UDP datagram containing a random number to port 1234 every 250 ms.

while true; do echo $RANDOM > /dev/udp/127.0.0.1/1234; sleep 0.25; done

I didn’t recall ever seeing a /dev/udp and so was a bit surprised that it worked.
Seemingly, a normal UDP socket was being created and written to using the regular sycall interface. That refuted my initial suspicion that some kind of a special file backed by the kernel was involved.
But who was actually creating the socket?
A peek at Bash’s code answered that question [...]

Heute Abend quäle ich mich zu einem Netzwerken-Event. Empfindet noch jemensch hier solche Veranstaltungen als sehr anstrengend?

Tonight I'm forcing myself to go to a #networking event. Does anyone here also find such events very exhausting?

Hi @Eduardo Thomas und @EmersonSch

Ein paar Tipps wie man am besten seinen ersten Beitrag verfasst. Es ist gut im ersten Beitrag den Hashtag "neuhier", also #neuhier einzubinden dazu noch ein kleiner Text, also zum Beispiel so:

What if any options are there for running Federated social networking tools on or through #OpenWRT or related router systems on a single-user or household basis?

I'm trying to coordinate and gather information for #googleplus (and other) users looking to migrate to Fediverse platforms, and I'm aware that OpenWRT, #Turris (I have a #TurrisOmnia), and several other router platforms can run services, mostly #NextCloud that I'm aware.

Is #diaspora itself viable on these systems? I'm thinking that may be ambitious.

If not, what are considerations for running a small node through a router? Primary considerations would be capacity planning, bandwidth and load impacts, and configuration and security considerations.

Hoping there's some expertise here.

Sitting at an API security conference.....
lot of really intelligent ideas and thoughts so far that have thus far ignored overt and blatant vulnerabilities to whatever their stack may be (i.e. chipset issues such as Intel's ME) and/or seem overly stuck in centralized model past.
Enterprise is on the verge of eating itself apparently..... stumbling giants with lots of brains, lots of talk, and next to no idea about what to do.

Nice event, but the amount of personal information required for signing up for this meeting is a puzzle.
