All, I am having problems writing to atftpd. I keep getting a permission denied error.
Switch#$.SED.bin tftp://169.254.180.65/c3550-ipservicesk9-mz.122-25.SED.bin Address or name of remote host [169.254.180.65]? Destination filename [c3550-ipservicesk9-mz.122-25.SED.bin]? !

So I doubt it is a firewall issue. I tried stopping IP Tables and I still get the same error. Any ideas welcome.
