[Asterisk-Users] TFTP question

[Hermann Wecke]

I'm trying to use TFTP to update the firmware on a Cisco ATA188 but I'm 
receiving this error:

hosts.allow and hosts.deny are empty, directory /tftpboot and files are 
readable by owner/group/others. Running tftpd (0.17-12) on Debian Sarge. 
Similar error message when running atftp.

Ideas?
