I was somehow sure I tried rsd1i before, but now I can see a 17x difference: # dd if=/dev/rsd1i of=/dev/null bs=1M count=1000 1000+0 records in 1000+0 records out 1048576000 bytes transferred in 6.038 secs (173,659,835 bytes/sec) Looking at iostat I see that using the "r" device causes transactions to go up to 64KB/t. Now, the real issue I had was with a slow ext2 file systems on the drive. I get 10MB/s reading the files and I observe 4KB/t in iostat. So, yeah, I can get faster transfers which means xhci and umass are capable of more than filesystems (at least ext2) extract out of them. Thanks Greg

You can add -DNOTAB in the Makefile to enable it, then grep for NOTAB and see how to allow using a different tab width per buffer. Then you'll have a diff for it, so you're issue will be solved, and you can share it on tech@ (cc'ing lum@). I for one would be happy to review such a diff, even if I can't give a meaningful OK.

Except possibly set up some kind of slow ping or other keep-alive mechanism. Since wireguard is stateless, if the dynamic IP is behind some kind of NAT, the ISP might break inbound connectivity if there is no outbound traffic for a certain period, (typically 2 minutes or so). This only matters if you expect to receive inbound connections without making an outbound connection first, (for example, inbound SMTP), because any outbound traffic should bring up the link anyway. IPSEC is another possible alternative.
Re: reminder: ports snapshots go with base snapshots
[ ... ] Just my user feedback, and only if it is wanted: I was not able to understand a damn thing from all the messages about this change. As an user, the "update" thing was always a voodoo for me. Ironically, the FAQ has exactly 3 (three) lines of text, one is the command itself (no offense intended to the maintainer, great job). So I was not able to understand the "update" action and I never used it and I have no plans to use it yet. I simply do a bare install from the scratch. As a damage assessment user cannot complain, they use what they get (both software and help) and I think they will go on with this. The developers understands more and can mitigate the effects. About the non communication and what happened, I think the involved parties must have a private talk. Thank you.

If you want to use a web API you can either run the cgi/php/whatever script unchrooted, or write to a file under /var/www which is read by a daemon/cronjob. You will probably be happier with wg(4) though, for this scenario with a static IP at one side you don't need to do anything special to maintain the tunnel, it "just works".and automatically follows changes of client IP. (I use it to route a /27 from colo to home which can be used across whatever connectivity I have so it works over mobile/landline/radio link/whatever). -- Please keep replies on the mailing list.
