[nylug-talk] ftp hangs after put

[Brian Gupta]

It's been awhile since I had to play with FTP and IPTables, but there is an
optional kernel module for FTP connection tracking that you should look
into. (I use sftp/scp for everything now, so I am rusty).

Let me know if you need further help...

Cheers,
Brian
