Package: openssh-server Version: 1:8.3p1-1 Priority: wishlist Tags: patch Hi, when having some daemon listening on another IP address on the same port as the regular sshd, sshd must not listen on wildcard. Because IP addresses might come up later than sshd on bootup, sshd might miss relevant listen addresses. The problem can be solved by either patching sshd to use IP_FREEBIND or using the attached template socket unit with systemd. Usage: systemctl enable --now ssh@192.0.2.42.socket ssh@[2001:db8::2a].socket Regards Timo Weingärtner -- ITscope GmbH Ludwig-Erhard-Allee 20 D-76131 Karlsruhe Tel: +49 721 627376-0 Fax: +49 721 66499175 https://www.itscope.com Handelsregister: AG Mannheim, HRB 232782 Sitz der Gesellschaft: Karlsruhe Geschäftsführer: Alexander Münkel, Benjamin Mund, Stefan Reger
