Hi
I have a cisco 831 router (c831-k9o3y6-mz.124-5c.bin) that cannot backup the config to a local tftp server. I have seen this behaviour on a few different cisco devices over the years and have never found a solution. The connection is made to the tftp server (in this case tftpd but similar behaviour on any tftp server) and a blank file is created on the target machine file system, but the data is never transferred.
The router shows %Error opening tftp://192.168.0.2/router-confg (Timed out) [Failed]
The tftpd log shows 5 repeated attempts at the file write.

This is also stopping me upgrading the image on the router as I cannot transfer in the other direction either.
Any suggestions would be welcome.
