But if two IP addresses are returned for the machine, sshd only takes one (the first?) into account, and misleadingly reports: Address x.x.x.x maps to foo.bar.com, but this does not map back to the address - POSSIBLE BREAKIN ATTEMPT! >How-To-Repeat: Use ssh from a client machine with multiple IP addresses to connect to sshd 1.2.22 >Fix: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-ports" in the body of the message
