Tested on Gentoo Linux x86. gcc (Gentoo Hardened 14.2.1_p20241221 p7) 14.2.1 20241221 my configure command and the summary at the end are here: https://bpa.st/2VPA emerge --info available here: https://bpa.st/LF7Q make tests returned all tests passed. It can talk to itself fine. It can talk to Gentoo's net-misc/openssh-9.9_p2 fine (client and server) It can login to both of the oldest sshd's I have: dropbear_2016.74 OpenSSH_7.5 Also, tested running it under tcpserver (ucspi-tcp) and it worked fine. My only concern is that ssh -v reported: debug1: Remote protocol version 2.0, remote software version OpenSSH_9.9 I double checked and that was the openssh-SNAP-20250404.tar.gz version saying that. Willing to do more specific testing if helpful. _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
