But it seems to be ObscureKeystrokeTiming, yes ? There are no references to that in the config on FreeBSD 14, so I assume it stays on, and at the default. Did this turn out to be the cause of the issue, and did disabling it fix the problem ? I have to admit I hadn't tried ssh'ing *out* of my test 14 box until today, but a quick try doesnt show any delays to anything. However I don't have anything running OpenBSD. -pete. PS: I did see an upgraded ssh cause delays in login a while ago. But that turned out to be dropping support for old key exchange algorithms. If the box you are sshing into is somewhat underpowered then it can take longer to do the key echange, as the newer algorithms are far slower. In my case the delay was 30 seconds to login.
