My RH 6.1 server will no longer accept FTP connections. I was successfully running my FTP server (for quite some time) using wu-ftpd, so I know that my system did work correctly in the past. Then I installed a new version of wu (2.6.0-1) as advised by a Red Hat security update. I can't verify that this is when my problem developed but I think it is. Anyway, after that any time I try to connect to the server the FTP client just hangs and won't ever make the connection. I thought it must be a problem with wu, so I removed it and installed proftpd, but I still have the same situation. A port scan on my machine reveals that port 21 is indeed open but I have no luck connecting. Any ideas?
