有些ftp服务器要 reverse resolve访问者的host name. 我不会用pureftpd，不过我搜索到
* Slow pure-ftpwho or slow login.

-> Sometimes, pure-ftpwho is slow to show the result. And sometimes, when an
user logs in, the session stucks a bit before he can get a directory listing.

This is probably caused by a slow DNS resolver. In order to display full
host names, pure-ftpd has indeed to make DNS queries that can be slow if you
link is slow, or if the client link is slow.

You can speed up pure-ftpwho and pure-ftpd with the -H switch. Names won't
be resolved, you will see IP addresses instead.
