[Solved] Ispconfig 3 pure-ftpd-mysql not working

Ispconfig 3 is an open source Cpanel for managing websites .I have been running Ispconfig 3 on our server ubuntu10.04 from last 6 months. I was running awesomely without any error. I was happy with Ispconfig 3 with its services and function. Last Night I came across strange problem that none of the ftp accounts are not working. Ispconfig uses Pure Ftp as Ftp program . I try restarting every services but also I am not getting into ftp accounts. Though I can see process of pure-ftpd-mysql , I was unable to login.

/etc/init.d/pure-ftpd-mysql status * pure-ftpd is running

I reinstalling package of pure-ftpd-mysql by :

apt-get install pure-ftpd-mysql.

Still not worked for me. In my syslog I only see that : ns1 pure-ftpd: (?@203.78.169.139) [INFO] New connection from 192.168.1.10 Oct 24 21:34:33 ns1 pure-ftpd: (?@xxx..xx.xxx.xx) [NS1] PAM_RHOST enabled. Getting the peer address Oct 24 21:34:39 ns1 pure-ftpd: (?@xxx..xx.xxx.xx) [NS1] Authentication failed for user [bikramkawan] Oct 24 21:34:39 ns1 pure-ftpd: (?@xxx..xx.xxx.xx) [NS1] Logout. Finally I checked in hosts.deny . In that file I saw there was uncomment on line

ALL:ALL.

Then I comment that line . Thus I am able to access ftp accounts.
