I've installed ISPConfig by this manual http://www.howtoforge.com/perfect-se...64-ispconfig-2
and now i receive every 30mins a message from ispconfig with text "WARNING: service ftp not running (server: hosting.mydomain.ru, port: 20)!", althrough ftp-server actually works fine and WEBUI in "Status" tab shows it as online. Proftpd listens 127.0.0.1 and 2 other real IP.
/var/log/messages - indicates clean start/restart if i restart it:
Sep 1 11:45:21 hosting proftpd: localhost.localdomain - ProFTPD killed (signal 15)
Sep 1 11:45:21 hosting proftpd: localhost.localdomain - ProFTPD 1.3.2 standalone mode SHUTDOWN
Sep 1 11:45:22 hosting proftpd: localhost.localdomain - ProFTPD 1.3.2 (stable) (built Tue Aug 25 13:53:29 YEKST 2009) standalone mode STARTUP
moreover, i cant find any errors in logs at all, but still gets this annoying emails...
Please tell me what's wrong
