Ftp Client not connect to host.

[immortalbikram]

I am having strange problem. My ispconfig 3 runs on ubuntu 10.04 . Its almost 6 months i am running this server and working good. Few days ago i upgrade packages of ubuntu . Now Ftp client like filezilla cannot establish to the server. It display Connection timeout. But when i try to connect ftp connection from my laptop to webserver with terminal , it gets established. I can see all folders of remote host (webserver). I look after log and cannot see any log. In log it show you are log in.
Help urgently needed.

Any errors in your logs?

Did you check the firewall? What are the outputs of

iptables -L

and

netstat -tap

?

You don't see any errors in the console when you restart pure-FTPd with something like

service pure-ftpd-mysql restart

do you? If not, what is the full command that is output when you start the service?

I have a VPS and I had to build pure-ftpd from source, or it would not start. You didn't do this in the past and forget to hold-back the package or something, did you?

Also, it would be helpful to know which software packages, exactly, were upgraded.
