* add connection limits (`limit' keyword in ftpd.conf) * move initialisation of curclass from parse_conf() to new function init_curclass() * implement count_users(), which determines the number of users in a given class. a file - /var/run/ftpd.pids-<class> - is used to store a list of pids in use (effectively an array of pid_t's), and its size is reduced as necessary. * new % modifiers in format_file: %c class %M maximum connection count %N current connection count * always end_login()s, even for refused connections bugs fixed: * remove \n from %T output * fix some inconsistencies in the man pages * ensure that both `ftp' *and* `anonymous' are allowed in ftpusers. (this was accidently broken in a recent commit to be ``or'' not ``and'') * use MAXPATHLEN not MAXPATHLEN+1 * crank copyright date on modified files * crank version
