I set up an FTP server by Serv-U 10.2. It ran normally until recently. Now I cannot connect it by FTP client. Everytime I make a connection, FTPRush will complain "Socket operation on nonsocket(10038)", and FileZilla "Status: Connection attempt failed with '-1'. Error: Could not connect to server". But if I connect my FTP by browser, like firefox, all goes well. Can anyone give hints on where the problem can be? Thank you~

Ok, just a punt. But is there a firewall issue? Possibly, the browser has a rule while the ftp client has not? – slotishtype Aug 5 '11 at 9:19
But I am working under PASV mode. – ziyuang Aug 5 '11 at 14:53
Doesn't matter that you are running PASV or not. If a firewall is going to block it, it will – Fazer87 Mar 7 '14 at 14:08
