Re: embarrassing mail problem
howdy Steve... on newer versions of openBSD open SMTPD legacy tls versions / ciphers are disabled by default... there is an option to allow legact tls versions ( i cant remember the option off hand but man smtpd.conf and search for tls you should find it handy enough...( this caught me out on an upgrade to 7.0 btw mxtoolbox.com has some useful tests that could help you diagnose mail flow issues... DMARC + DKIM would be worth looking at... also check the spamhaus PBL... if your isp suddenly added their subscriber ip ranges to the PBL this could negatively impact you if your mail server ip is in the ranges the ISP included in Spamhaus Policy Block List... hope this helps On Wed 5 Oct 2022, 23:07 Steve Fairhead, wrote: > I've searched and failed, and I realise I'm going to show my total > ignorance by not having found an answer (and no, I've not been keeping > up these last few years - mea culpa - demanding day-job).

embarrassing mail problem
I've searched and failed, and I realise I'm going to show my total ignorance by not having found an answer (and no, I've not been keeping up these last few years - mea culpa - demanding day-job). But - I'd be grateful for any (gentle or otherwise) cluebats. I have several OpenBSD email servers, some elderly (Sendmail) and some brand-spanking new (smtpd). Recently I've noticed that some (of both kinds) are failing to deliver mail to some major UK ISPs. (Mostly domestic; business ISPs not so much.) For Sendmail, the error is "TLS handshake failed"; for smtpd, it's "Network error on destination MXs". I do have SPF etc setup; thought that might be it, but no. I've read that some ISPs have closed port 25. I presume that's relevant, but I simply don't know. As I said, all cluebats gratefully (and probably painfully) accepted.

CURRENT: scp stalling & stopping all networking
$ ssh -V OpenSSH_9.1, LibreSSL 3.6.0 scp has been stalling on my system and hanging up my networking stack. I am probably doing this wrong, but I have been having to delete, down, up and sh /etc/netstart to recover networking, or doing a reboot. It seems to happen with larger files, whether I use the -O flag for legacy or not. I have tried sending to: - FreeBSD 13.1 (8.8) - Rocky 8 (8.0) - Ubuntu 22.04 (8.9) I have not been doing an path expansion to the dest path. I tested from OpenSSH 9.1 -> 9.1, no problem. This is the output I get when running scp to a host with an older ssh version: scp: debug3: SSH2_FXP_STATUS 0 scp: debug3: In write loop, ack for 1346 32768 bytes at 43941888 scp: debug3: Sent message SSH2_FXP_WRITE I:1411 O:46071808 S:32768 scp: debug3: SSH2_FXP_STATUS 0 scp: debug3: In write loop, ack for 1347 32768 bytes at 43974656 scp: debug3: Sent message SSH2_FXP_WRITE I:1412 O:46104576 S:32768 scp: debug3: SSH2_FXP_STATUS 0 scp: debug3: In write loop, ack for 1348 32768 bytes at 44007424 scp: debug3: Sent message SSH2_FXP_WRITE I:1413 O:46137344 S:32768 scp: debug3: SSH2_FXP_STATUS 0 scp: debug3: In write loop, ack for 1349 32768 bytes at 44040192 scp: debug3: Sent message SSH2_FXP_WRITE I:1414 O:46170112 S:32768 scp: debug3: SSH2_FXP_STATUS 0 scp: debug3: In write loop, ack for 1350 32768 bytes at 44072960 scp: debug3: Sent message SSH2_FXP_WRITE I:1415 O:46202880 S:32768 scp: debug3: SSH2_FXP_STATUS 0 scp: debug3: In write loop, ack for 1351 32768 bytes at 44105728 debug2: channel 0: rcvd adjust 131072 I just did a sysupgrade -s today before posting. As it stands, with 9.1 I can't scp to versions of ssh older than 9.1.

Thanks for any comments / recommendations. (I want something that lives on my machine. I know there are some 'big' frameworks, perhaps MediaGoblin, Serviio; also I could perhaps run a docker with minnich under a virtual machine runing linux. But is there something easy and available on OpenBSD?) Best regards, Ruda Hi, I have been running piwigo (https://piwigo.org/) as a "Gallery" for all my photos and videos for years. It takes a bit of work, but it does a good job and "just works". It takes a small amount of work to configure php, phpfpm, but once that's all done, it's rock solid. Kind of cool, it allows multiple formats of photos, so I can have my camera shoot jpgs and raw and it will provide the option of which to view. For videos, you can create a thumbnail from the video so the user has a bit of a clue what they might be going to watch. Good luck! Cheers, Steve Williams
