CW tftp failure

[georgeef1]

Hi,

When attempting tftp backup from certain devices the transfer fails with

a permission denied.

I've got 420 devices that can tftp config backups to the ciscoworks

server without issue. Three sequentially-numbered devices cannot. Below is the result of a

tftp test from a failing device, as well as a packet capture from the ciscoworks server.

In order for TFTP to work, the file has to exist on the server first.

So, create an empty file in NMSROOT\tftpboot, and give casuser full control over the file. For example, create an empty test.bin in tftpboot. Then try your experiment.

Had the same problem while using tftpd64 with c7200.

In my case, uninstalling the tftp server (also removing the default path folder), and reinstalling worked!

It has happened a couple of times, now, and reinstallation is the only thing that worked for me both times.
