How to solve it? Slow connections tend to point to broken reverse DNS resolution. Most daemons will reverse-lookup your IP address on connection, and if that info is bad or unavailable, it will time out and slow things down. For your bind problem, perhaps something is already running on port 2323? Check netstat.
