I am trying to FTP a large file from one server is one location to another server in a different location. However, the file transfer terminates in middle. Here is the file information and outputs.

The file size is: 2622278144 bytes

This is the command I used to transfer the file.

ftp> put encyc.tar
200 PORT command successful.
150 Binary data connection for encyc.tar .
226 Transfer complete.
local: encyc.tar remote: encyc.tar
325402624 bytes sent in 1.3e+03 seconds (238.86 Kbytes/s)

However, as you can see only 325402624 bytes were sent. What is causing the FTP To terminate? The transfer runs for  about 20 minutes before it terminates.

Hard to say. How reliable is the network link between the two locations? And what OS and FTP server & client are involved?

OS is SOlaris 8. Link is pretty good. As you can see, it says it completes fine.

Have you retried the transfer, and does it halt at exactly th same number of bytes?

Check that the userid you are using to log in to the remote server does not have a quota or ulimit set (and that there is space on the filesystem!); Tho' I'd would have expected an error message instead of "Transfer complete" if the remote server had been unable to write the file  for any reason...

Is there a WAN link involved in this connection? Or is it purely ethernet? If it were to be ethernet I'd suspect a link mode negotiation problem given the reported speed and failure.

OK, the problem was with another JOB trying to FTP a file to overwrite the one I was FTPing. In short, there was a job conflict that was killing my FTP.

That explains it.

What would you like to do with this question? It was obviously something that we would not have been able to solve.

Basically your FTP client or FTP server does not support files over 2G in size, in dangerous way - via integer overflow in file size calculation, you should change at least client, and if this does not hel, server is vulnerable too.
Another solution is to compress file uzing gzip, bzip, compress or whatever you like.
