For about two months I have a problem with creating a backup from the other server. I have two servers. One is clearos is running web, ftp, mail. A second server is running billing ... Every night at about 2:00 creates backup copies of billing and the FTP Clearos. It all worked until 12/04/2013 when the updated app-flexshare. Since then it's been about 2-3 updates app-flexshare but I still did not work. Still writes:
Feb 14 02:02:26 shark proftpd [1168]: 10.204.101.1 (10.204.101.5 [10.204.101.5]) - USER ispzaloha: Login successful. ...

10.204.101.1 is internal IP address for Clearos
10.204.101.5 is IP address for billing server 

I've tried everything I found on the web. One thing that I think it is wrong:

In the file :/etc/passwd - i have : flexshares:x:492:492:Flexshares:/var/flexshares:/sbin/nologin - I have yet to servers: / var / flexshare - I do not know if there is a typo or the way it should be. That "s" at the end of /var/flexshares

chmod for pam_env.conf is 0644. To be executable?

Thanks for help friends.
