Angry ubuntu server edition and tftp problem when PUTTING files.


I installed tftp as per this document:
http://icesquare.com/wordpress/solve...ess-violation/

I followed this to the letter 3 times and every time I put a file I get:

root@CiscoCFG:~# tftp localhost
tftp> put test
Error code 2: Access violation
tftp> root@CiscoCFG:~# tftp localhost
tftp> put test
Error code 2: Access violation

If I touch the file name chmod 777 the file then do a put it works perfectly fine.

My config is as follows:

service tftp
{
protocol = udp
port = 69
socket_type = dgram
wait = yes
user = nobody
server = /usr/sbin/in.tftpd
server_args = -s /svr/tftp
disable = no
}

the directory /svr/tftp permissions are 777:
drwxrwxrwx 3 nobody nobody 4096 Nov 14 10:32 svr

This thing should have full permissions as would anyone who wanted to write or read from that directory. I see nothing in the logs im really stumped on this. If the file is already in the directory I can read it all day long, I just cant make NEW files, can not put them, but I can do get's, I can only put to an existing file with permissions @777.

When I TOUCH the file ahead of time locally on the server, chmod it to 777 I can then send the file to the tftp server but thats not a valid work around, Cisco switches and routers cant log in, touch a file then send it.

Quote:
--create, -c
Allow new files to be created. By default, tftpd will only allow upload of files that already exist. Files are created with default permissions allowing anyone to read or write them, unless the --permissive or --umask options are specified.
