Hi,

Which is the best method / tool to FTP very large files(around 5 - 6 GB) in HPUX over WAN ??

Shalom,

ftp is probably fastest.

scp encrypts the authentication and data stream but will be slower.

scp is part of secure shell available at no cost at http://software.hp.com

you can try cuteftp pro which enhances the large file transfer.

Ramesh,

Just gzip the file first and then use scp or ftp that will be fast as you have compressed the file.

in my opinion don't use scp for large files.
encription will take more time.just try ftp,if time is important for you.

ftp is the fastest but over a WAN, things become a lot different. Even if you have a T3 link (45 Mbit), the turnaround time (aka, ping time) can really take it's toll. ftp minimizes this effect by allowing overlapping data and response packets. scp and other simple copy tools send a packet and wait for a response. Since the WAN will be so very slow (compared to a disk or even a local LAN), you may have to concentrate on compression to reduce the amount of data to transfer.

I am afraid for the size of 5~6 GB, none of those will work easily. CHeck your systems limitation first.
If you could, I suggest to use BitTorrent applicaitons.

Make sure the ulimits for the user is set to the maximum and transfer it using ftp/sftp/rcp/scp
