Changement d'instance veut dire nouvelle (enfin première même) #introduction !

Qui suis-je ?
Nicolas, consultant en #actuariat pour les compagnies d'assurances la semaine et #grimpeur le weekend.

Je m'intéresse à de nombreux sujets notamment IT (projets #opensource, #dn42).

Au plaisir de vous lire !

One of the stupidest things I've ever seen: In #Chromium-based browsers, if the #CSP header "form-action 'self';" is set, the page that is called after submitting the data must not have a 302 redirect. A possible workaround would be a page that redirects via JavaScript or via HTML meta tag. Therefore, I don't see the security benefit that this behavior offers. Firefox allows such redirects.

For me, this means that my web application BgpLookup only works in Firefox.

#dn42 #wireguard

Hm. I can ping my peers link-local #wireguard address, but not the "ULA" one, although I configured wireguard-quick as per https://dn42.eu/howto/wireguard

ping just seems to "hang".
...

however, tcpdump brings the solution. I didn't set the IPv4 address, assuming IPv6 address suffices.
Somehow the replies comes back from IPv4?

My #dn42 application was successful.

Now to find peers, and set up the infrastructure. But that's a weekend project for some time.

Maybe I'll give #dn42 a shot?

Systemd and Linux Network Namespaces together are terrible, although each is very nice individually. I have seperated clearnet access and dn42 access via netns in a lab setup. For each program I wanted to use in both namespaces, I had to copy-paste and customize the Systemd unit. This is terrible. Too bad Systemd doesn't support this natively, but only with tricks.

#systemd #dn42 #networking #linux #netns #NetworkNamespaces

What kind of reason is "I don't like the concept"?

Personally, I find netns very handy because you can easily isolate networks (for example, dn42 and the Clearnet). This is also what Kioubit does in dn42, for example. To reject a proposal with this reasoning I think is wrong.

Pinging the dn42 with kterm on a Kindle Paperwhite over a Freifunk (ICVPN) hotspot.

I wrote something about Route Selection in BGP and how to influence it.

@benjojo "dn42.tools is reached end of life" Oh no :-( #lookingglass #dn42

I really want to build an open and decentralized network similar to #dn42 to practice a bit with #network #engineering. The beautiful thing is that there is literally a wealth of resources to be had simply for #googling. Anyone interested in collaborating?

Da schaut man in den #IRC und pünktlich zu Neujahr fängt der @frainz mit #dn42 an :D

@ClouD Jetzt ist das ja zum Glück nicht mehr schlimm. Er ist ja kein Border Router für's #dn42 mehr :D

TIL: Der v4-Teil des #dn42 ist von Welt erreichbar

Betreibt jemand ein #dn42 Router in Berlin nahe DFN und mag mit mir peeren?
Die Ping von 5ms muss ich ausnutzen ^^
