> Lesson #3: It is polite to log interesting information at default levels and deliberately dropping a connection for any reason is definitely interesting to system administrators. Agreed. But I suppose part of the reason this feature is present is because so many ssh servers are the targets of attacks, often brute force. So logging these might be problematic. Speaking of "Rate limiting" -- openssh logging something like "dropped N connections exceeding MaxStartups" once per minute (if N > 0) [at WARN level] seems like a sane compromise.
