Warnung an alle, die dieses Gist finden: Ich habe hier nur dokumentiert, was ich im Rahmen einer Umstellung herausgefunden habe. Es gibt Garantie auf Richtigkeit der Informationen, Zusammenhänge oder ob das unter allen Umständen wie hier beschrieben funktioniert.

Predictable Network InterfaceNames

Debian stellt auf ein anderes System von Namen für Netzwerkinterfaces um. In Debian 9 gehen noch die alten, manuell festgelegten - was der Standard ist, wenn man von Debian 8 aktualisiert.
Ab Debian 10 wird dieses System, welches mit udev und systemd zusammen hängt, zum Standard.

Mit zless /usr/share/doc/udev/README.Debian.gz kann man Debian-spezifische Informationen zu dem Thema finden.
Unter anderem auch, dass (und wie) man diesen Mechanismus in Debian 9 Stretch umgehen kann.

tl;dr:

• mostly, hosts ignore the mss sent
• most of the interesting behaviour comes from the extremes: mss=1 and mss=1440
• setting mss=(an atypical value, say 1275 or 1411) ought to spot hosts that simply reflect MSS values
• setting mss=1024 apparently will spot a bunch of (Microsoft?) hosts returning MSS=956
• passively, mss=1220, 1360, 1410 may help identify CDN/non-CDN nodes inside yahoo/edgecast, google, facebook respectively

Longer version: captured SYN+ACK+MSS values:

Variation is less than I initially thought; just enough for me to notice

channel operator quick reference

direct discussion about administrative action away from the main channel and into #reddit-diabetes-ops to minimise disruption. our -ops channel is the place where users should come to ask for our help. examples:

• any sort of operator request or discussion of channel administration in the main channel
• PMs asking why a ban was set
• reports of harassment (unless the user is confiding in you)
• any request for operator action
