Hi,

Use 3COM Daemon V2.0 Rev 10

I have used 3Cdaemon suggested by Dandy with good success. As an alternative I have heard good things about tftpd32 and its support for features like large file size. It is available from:

http://tftpd32.jounin.net/

I would also like to make the suggestion that as file sizes of IOS get larger there are benefits from using FTP instead of TFTP. Not only does FTP not have a file size restriction but the performance of FTP for transferring large files is much better than the performance of TFTP.

". . . the performance of FTP for transferring large files is much better than the performance of TFTP."

Very, very true as latency increases, as you often see on WAN links. (NB: RCP also works well too.)

I agree with Joseph. I would rather use FTP when the file size goes beyond 32 MB.
