I just realized that some monitors (e.g. LG 27UD88) can connect via USB-C directly, whilest serving as a USB hub and power source. Would this be expected to work as well?

It should work fine because the USB-C ports have DisplayPort signaling built-in and I would not expect any issues. https://www.displayport.org/displayport-over-usb-c/ HDMI 1.4 does not support 4k at 60Hz like HDMI 2.0 does but HDMI 2.0 is not supported as you found out. I have not tested USB-C to DP specifically with my NUC6i7KYK but it does drive 4k over DisplayPort which should be the same with USB-C to DP. I do get some weird artifacts like the screen "shaking" back and forth a bit until I launch Xorg which then works perfectly. Bryan
Re: automatically rotate isakmpd.pcap
On 2018-06-28 10:18, Federico Donati wrote: With newsyslog, logs are being rotated, but new file "isakmpd.pcap" is not usable with tcpdump (message is "tcpdump: bad dump file format"). I've also tried to stop isakmpd writing isakmpd.pcap (echo p > isakmpd.fifo), but it didn't work. Ok, this workaround works: conf file: # cat newsyslog_ipsec.conf /var/run/isakmpd.pcap root:wheel 600 30* $D0 ZB "rm /var/run/isakmpd.pcap ; echo p on > /var/run/isakmpd.fifo" command to be run: # echo p off > /var/run/isakmpd.fifo; newsyslog -Ff newsyslog_ipsec.conf -v Newsyslog creates an empty file during the rotation. Tcpdump doesn't like this file, so I need to stop the writing of isakmpd.pcap, rotate the log, remove the newly created file and activate the logging again (so isakmpd will create its working pcap file). This actually works, but I have to put in crontab rather than inside /etc/newsyslog.conf, and I find this pretty ugly. It would be nice if newsyslog had a "prerotate" function, something like logrotate. I'm always open to suggestion if you had similar needs. Bye

So thanks for pointing this out, you saved me from buying the wrong cable. https://ark.intel.com/products/95451/Intel-Core-i7-7500U On Fri, Jun 29, 2018 at 3:05 AM, Mike Larkin wrote: > Oh, just noticed the USB-C bit.

This review (in German) says it works, but presumably on some other OS. https://notebooks-und-mobiles.de/asus-zenbook-ux390ua-laptop-im-test Thanks!
ber.3 diff from last ber source commit
I mistakenly committed modifications to the ber.3 man page (in snmpd).
This man page is currently not linked into the build.
I am sending this diff post-commit for visibility only.
A work in progress. Comments welcome.

State of Yubikey/U2F support on OpenBSD
I've been experimenting with switching over one of my laptops to OpenBSD, but there is one main problem stopping me from switching. The support for Yubikeys and U2F. I'm try to gather a list of things that currently doesn't work. And maybe find some collaborators to investigate and maybe fix the issues. So if you are interested to work on any of these or have further information please post on this thread. A) Yubikey-manager (ykman) is the new Yubikey CLI. I got it to install but only one out of three transport (protocols) works. OTP works. CCID fails connecting to the Yubikey via pcscd, further investigation needed (this is hopefully not to hard to fix). FIDO doesn't work since the pyu2f library doesn't support OpenBSD, this is probably not to hard to fix. I'm tracking these in [1]. B) Chromium (v 65.0.3325.181) crashes when U2F auth is requested and a key is inserted, see [2]. I haven't yet debugged this, but fixing this probably requires a fair amount of knowledge about Chromiums internals. C) Firefox (v 59.0.2) doesn't officially support U2F but have a config option to enable this [3][4]. Unfortunately this doesn't work on OpenBSD (but macOS for example). (Firefox 60 is supposed to support the new FIDO2 standard this might improve on U2F support too.)
