Apr 16 16:26:33 <Knaldgas> Running BeagleBone Blue as AccessPoint, Tethering.Identifier is only used with Tethering=true. Can I change SSID without enabling tethering?
Apr 16 16:30:28 <rcn-ee[m]> default ssid is set in /etc/default/wl-18xx
Apr 16 16:34:31 <Knaldgas> rcn-ee[m], thanks. On my BBBlue its "bb-wl18xx", but your hint helped me :)
Apr 16 16:34:55 <rcn-ee[m]> opps, yeah that file..
Apr 16 17:07:54 <CoffeeBreakfast_> Any quick intro or "in a nutshell" about Unix domain sockets out there? any article, lecture?
Apr 16 17:16:04 <zmatt> my guess would be "yes"
Apr 16 17:18:16 <zmatt> though the really short summary is: pretty much like TCP sockets, but instead of ipaddr+port you use a filesystem path
Apr 16 17:21:24 <zmatt> the only weird caveat is that the "socket" created in the filesystem by bind() needs to be manually unlinked... bind() will fail if anything already exists at the given path, even if it's a socket which has been closed (e.g. the process that created it died)
Apr 16 17:22:52 <zmatt> (if your server uses systemd socket activation then it doesn't need to worry about it, in fact in that case it doesn't even need to care whether it's a tcp socket or unix domain socket)
Apr 16 17:29:06 <CoffeeBreakfast_> suppose I have a UDS listed by netstat -a. Is there any command line to watch a particular socket, to see the data? just curious, as always
Apr 16 17:31:25 <zmatt> I don't think there's a facility for sniffing domain sockets, but I'm not 100% sure
Apr 16 17:34:51 <zmatt> you could build a kernel with suitable options support SystemTap and use that: https://sourceware.org/systemtap/wiki/WSunixSockets
Apr 16 17:35:06 <zmatt> or strace one of the processes
Apr 16 17:35:35 <zmatt> or man-in-the-middle the socket connection (but that won't work for existing connections of course)
Apr 16 17:37:19 <CoffeeBreakfast_> strace sounds good
Apr 16 17:43:00 <zmatt> kinda weird that there's no facility for this
