--U0ygNhoH699P9y8v Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable (This may also apply to head; I haven't tested it recently, and testing is a little awkward for me just now. -- dhw) As I type, I am 9 time zones east of home. The laptop I am using is running: FreeBSD localhost 13.1-STABLE FreeBSD 13.1-STABLE #468 stable/13-n250522-48= a5e3fc6568: Wed Apr 20 05:25:39 PDT 2022 root@g1-48.catwhisker.org:/com= mon/S3/obj/usr/src/amd64.amd64/sys/CANARY amd64 1301501 1301501 I have seen an apparently-similar set of symptoms on a different laptop (that I use for the bulk of my day-to-day activities when I am not wandering about (e.g., in different time zones)); it was running: FreeBSD 12.3-STABLE #1236 stable/12-n235174-879a6b7b628: Tue Apr 19 03:32:1= 2 PDT 2022 root@g1-70.catwhisker.org:/common/S1/obj/usr/src/amd64.amd64= /sys/CANARY amd64 1203507 1203507 when I last observed the issue. In each case, I have no problems associating (if using wireless) and acquiring a DHCP lease at home (where the DHCP server is net/isc-dhcp44-server (isc-dhcp44-server-4.4.2P1_1), currently running: FreeBSD 12.3-STABLE #59 stable/12-n235169-6def5bc64cb: Fri Apr 15 03:31:41 = PDT 2022 root@freebeast.catwhisker.org:/common/S1/obj/usr/src/amd64.amd= 64/sys/ALBERT amd64 1203507 1203507 ), nor do I see the problem if I have either laptop associate to my phone's "hotspot". But at the hotel where I am no, as well as on the commuter shuttle bus at work, and a hotel in Los Angeles back in March, I found that dhclient on the laptop would issue DHCPDISCOVER (repeatedly)... and utterly fail to recognize any response from a DHCP server. In searching for solutions, I found a thread, " dhclient does not decode 802.1q-encapsulated replies #114 " at https://github.com/opnsense/src/issues/114 - I have no idea if it's related to what I am seeing. (While I don't use OPNSense, I do use ipfw (and have, since around 1999). I am not at all familiar with VLANs -- I don't use them in my networks.) I do use an /etc/dhclient.conf; here are the non-comment lines: | send host-name ""; |=20 | request ntp-servers, smtp-server, routers, domain-name-servers, domain-se= arch, domain-name, subnet-mask, broadcast-address; though the mtime on that file shows Aug 15 04:40:08 2018 (at which point I know the shuttle bus DHCP was working for me). As you may be able to discern, while I do have connectivity enough to send/receive email, my opportunities for checking and testing are likely to be quite limited -- more so in a couple of days, once the cycling tour actually gets under way.
