How to use TFTP clien on linux correctly?

Dims · 06-05-2009, 06:54 AM

I have started Tftpd32 on my windows box and it works fine since linux machine is bootable from network card.

But when I am trying to get pxelinux.0 file with the help of tftp client, I get timeout error.

My conversation is:

Code:

[root@testbed tftptest]# tftp
(to) 192.168.10.5

tftp> binary

tftp> get pxelinux.0
getting from 192.168.10.5:pxelinux.0 to pxelinux.0 [octet]
Transfer timed out.

At the same time Tftpd32 program shows tranfer windows appearing, but with zero progress bars in them. Multiple windows appear sequentially as if tftp client tries to download file multiple times.

What is going wrong? How to use tftp client?

I found winfows TFTP client and it also can't retrieve file from linux tftp server. But can from windows. Is it possible that two TFTP protocols exist?
