Eyal,

You want to be on the most current version of the ARPA Transport executables
which addressed some momentary hangs in ftp. You may also have to run a nettl
trace to pinpoint the reason for the failure.

Eyal,

I'm having the same problem. Were you able to resolve yours? How?

Hi Eyal,
This problem usually occurs if you are going through a firewall or a router with access lists enabled. With FTP you must also allow all ports greater than 1023 becuase a second TCP connection for the data is made from server to client. This is very dangerous so you might want to think about changing your client to a passive one if you are going through a firewall or router with ACL's
Hope this helps.

Hi,

Instead of using ftp which transmits userid/password and data traffic in the clear, perhaps you should give Secure Shell's sftp or scp a try. sftp and scp encrypts your network traffic and eases management at your firewalls because it uses only a single port 22 for both control information and data.

Regards.
