How can I send the file without manual creation? I am using xinetd service for tftp server. And below is its config file: #/etc/xinetd.d/tftp : service tftp { protocol = udp port = 69 socket_type = dgram wait = yes user = root server = /usr/sbin/in.tftpd server_args = /tftpboot/ disable = no } Please suggest changes to make it working without creation of a file in server. linux tftp share|improve this question edited Mar 22 at 9:21 runner 134112 asked Apr 6 '15 at 14:44 shah_pankil 1614 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote So this is how I debugged the issue. # tail /var/log/syslog The output of the above command said tftpd

Although the post was written for Ubuntu, the same idea can be applied to all systems. 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: tftp> get myfile.jpg Error code 2: Access violation If you google the error message, Error code https://icesquare.com/wordpress/solvedtftp-error-code-2-access-violation/ 2: Access violation 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? Anyway. I am not sure what cause the TFTP gives the error message: Error code 2: Access violation. 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. My TFTP Configuration: service tftp { protocol = udp port = 69 socket_type = dgram wait = yes user = nobody server = /usr/sbin/in.tftpd server_args = var/lib/tftpboot -s disable = no } There are couple things you need to pay attention. First, my TFTP root directory is /var/lib/tftpboot, and in my configuration file, I skip the first /. Second, I put a flag, -s in the server_args. That helps to keep TFTP from complain. Next, the permission of the TFTP root directory plays an important role. Make sure that the permission and ownership are set correctly. sudo chown -R nobody:nobody /var/lib/tftpboot sudo chmo7 -R 777 /var/lib/tftpboot Now, you can simply restart the system: sudo service xinetd stop sudo service xinetd start and try to put a file and download it back: tftp localhost tftp

I have not tried tftpput on u-boot. From the command help it appears address and size must be supplied by the command line. I would try that.

pool of using diskless Ubuntu. Basically the client computer downloads the necessary files from the Ubuntu server every time during the boot. To keep things simple and easy, Ubuntu does that by using TFTP. So the first step is to set up a TFTP server on the server. For those who haven’t heard of TFTP, it is similar to FTP, except that it has no security feature, and the function is extremely limited. Anyway, here is how to set up a TFTP server on Ubuntu 11.10: Installing TFTP sounds easy. However, I’ve heard that many people experienced many issues during the installation, such as Error code 2: Access violation issue. That’s why I create this tutorial. If you follow exact the same steps, you will not experience any problem. First, let’s install all the necessary packages: sudo apt-get install xinetd tftpd tftp -y Next, we need to create a configuration file: sudo nano /etc/xinetd.d/tftp Put the following content into the file. service tftp { protocol = udp port = 69 socket_type = dgram wait = yes user = nobody server = /usr/sbin/in.tftpd server_args = var/lib/tftpboot -s disable = no } In the server_args, I have var/lib/tftpboot, which represents the location of the tftp root, i.e., /var/lib/tftpboot. Notice that I skip the root /. Now let’s change the ownership of the directory: sudo mkdir /var/lib/tftpboot sudo chown -R nobody:nobody /var/lib/tftpboot sudo chmod -R 777 /var/lib/tftpboot and start the TFTP service: sudo service xinetd stop sudo service xinetd start Verify the TFTP is running correctly or not: netstat -na | grep LIST | grep 69 You should see something like this: tcp 0 0 0.0.0.0:69 0.0.0.0:* LISTEN Test: Upload a file to TFTP Server Now let’s test the TFTP server by logging into the server first: tftp localhost and upload a file: tftp> put myfile.jpg Sent 56733279 bytes in 5.7 seconds Quit: q Make sure that file has been uploaded: ls -l /var/lib/tftpboot Test: Download a file from TFTP Server Now, let’s go to a different directory and download the file we just upload. cd some_other_directory and log in to the tftp server again: tftp localhost and get the file: tftp> get myfile.jpg Received 56733279 bytes in 5.7 seconds You are done. Troubleshooting (e.g., Error code 2: Access violation) If you see a message like: Error code 2: Access violation Make sure that you: - Follow the exact procedure in this tut
