First the setup: My Pc has only the ip-Address 192.168.11.1, but I somehow was confused and entered the following into sshd_config: ListenAddress 192.168.11.2 ListenAddress 192.168.11.1 ListenAddress 192.168.11.3 and LogLevel DEBUG I strace the sshd with following results: 23878 bind(4, {sin_family=AF_INET, sin_port=htons(22), sin_addr=inet_addr("192.168.11.3")}}, 16) = -1 EADDRNOTAVAIL (Cannot assign requested address) 23878 bind(5, {sin_family=AF_INET, sin_port=htons(22), sin_addr=inet_addr("192.168.11.1")}}, 16) = -1 EADDRNOTAVAIL (Cannot assign requested address) 23878 bind(6, {sin_family=AF_INET, sin_port=htons(22), sin_addr=inet_addr("192.168.11.2")}}, 16) = 0 This resulted in the sshd listening on the port 22, but *also* on two higher ports on the same machine, somehow random. The logging give false information that the sshd listens on the two wrong interfaces on port 22, I don't know if this is really a bug, but it is sure to confuse me.
