Hello, I just ran upon this problem and couldn't find it in bugzilla. SSH crashes (abort trap) if all of the following conditions are met: (a) option -f is used (crash happens when going to background), (b) reverse port forwarding is set up (option -R), (c) option ExitOnForwardFailure is enabled, (d) there are no actual port-forwarding failures. The problem can be reproduced by

Using OpenSSH_8.3p1 I had an open (working) connection to some other box; after a bit of inactivity, some device in the middle seems to have forgotten about the TCP connection (NAT) and broke it. I've got an EscapeChar defined, though; so first I tried to send a BREAK and, when that didn't help (TCP already gone, packets get lost!), I tried (just out of curiosity) a Rekey. Now I can see

Hi! as I just noted, after scp the connection does not shut down properly. When I do a "scp file targethost:path", on targethost a "sshd" process is left running. I do use --with-default-path="/usr/local/openssh/bin:/usr/bin:/usr/local/bin" to assure, that the corrensponding openssh-scp is used. It also seems, that normal sessions are not always closed properly.

Hi, OpenSSH 8.0p1 is almost ready for release, so we would appreciate testing on as many platforms and systems as possible. Snapshot releases for portable OpenSSH are available from http://www.mindrot.org/openssh_snap/ The OpenBSD version is available in CVS HEAD: http://www.openbsd.org/anoncvs.html Portable OpenSSH is also available via git using the instructions at
