I've encountered an odd error state that I haven't been able to resolve yet. I have a customer that, for what ever reason, wants to use active mode occasionally for FTP xfers. What they have noticed, is that after you switch to active, and issue a command (they do 'ls', I've done other things like 'put' and 'get', etc.), the connection hangs. If you wait a bit it returns with a "425 Failed to establish connection". I've tried this on three hosts so far (all CentOS 5) and they all behave the same, some of which there is effectively no firewall (all traffic is allowed from my workstation to the host, and no restrictions on exiting traffic).
All google searches about this behavour thus far have talked about old versions of vsftpd or using filesystems such as FAT, which don't apply in all cases. Any ideas?
