This post is an extension of my original post on TFTP: How to Setup TFTP<\/a>. Although the post was written for Ubuntu, the same idea can be applied to all systems.<\/p>\n

So, here is our problem. You set up a TFTP server. It starts fine. You upload a file, it gives no error. Now, you try to download a file, it throws you an error:<\/p>\n

\r\ntftp> get myfile.jpg\r\nError code 2: Access violation\r\n<\/pre>\n
If you google the error message, Error code 2: Access violation<\/strong> on the web, you’ve probably noticed many solutions, some of them are very creative, such as running a touch command to create the file before downloading it etc. Before you try those solutions, ask yourself this question first: Do you want to touch 100 files before you download 100 files?<\/p>\n
Anyway. I am not sure what cause the TFTP gives the error message: Error code 2: Access violation<\/strong>. However I never experienced this error in my system before with my configurations and settings. Therefore, I am going to share you my configurations for your reference.<\/p>\n
My TFTP Configuration:<\/p>\n
\r\nservice tftp\r\n{\r\n   protocol = udp\r\n   port = 69\r\n   socket_type = dgram\r\n   wait = yes\r\n   user = nobody\r\n   server = \/usr\/sbin\/in.tftpd\r\n   server_args = var\/lib\/tftpboot -s\r\n   disable = no\r\n}\r\n<\/pre>\n
There are couple things you need to pay attention. First, my TFTP root directory is \/var\/lib\/tftpboot<\/strong>, and in my configuration file, I skip the first \/. Second, I put a flag, -s<\/strong> in the server_args. That helps to keep TFTP from complain.<\/p>\n

\nNext, the permission of the TFTP root directory plays an important role. Make sure that the permission and ownership are set correctly.<\/p>\n
\r\nsudo chown -R nobody:nobody \/var\/lib\/tftpboot\r\nsudo chmo7 -R 777 \/var\/lib\/tftpboot\r\n<\/pre>\n
Now, you can simply restart the system:<\/p>\n
\r\nsudo service xinetd stop\r\nsudo service xinetd start\r\n<\/pre>\n
and try to put a file and download it back:
\n<\/p>\n
\r\ntftp localhost\r\ntftp> put myfile.jpg\r\nSent 56733279 bytes in 5.7 seconds\r\n\r\ntftp> get myfile.jpg\r\nReceived 56733279 bytes in 5.7 seconds\r\n<\/pre>\n
That’s it.<\/p>\n
Happy TFTP.<\/p>\n
