I am using tftp for an embedded linux project I am working on. I need to be able to use the put command from the client. I do not know how to set the server options needed to write files to the host. I think I need permissive and create options but I do not know how to set them. Not for lack of trying. I think I wore out xinetd due to excessive restarts. lol I know...man page says... in.tftpd[options...] directory... Do I append /etc/xinetd.d or simply use the command line? Please give an example with correct syntax. The directory I want to write to is 777 owner nobody. Garbage in equals garbage out. I need help to take out the trash. Thanks in advance, Mike ADDENDUM 1

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. I don't know where RAM is on your platform so I can't give a valid example command line but it should look something like: tftpput 80000000 10 ---- Old answer, may still be useful if the above does not help If it were me I would run wireshark on the tftp server to see what is happening. If you can't do that you can use a hub (not a switch) on the device and plug a pc into the same hub to run wireshark. (hubs are hard to fi
its simplicity and low memory requirements Below the installation steps used on a computer loaded withLinux Mint 14. In the man documentation for tftpdwe see the below paragraph : The use of tftp(1) does not require an account or password on the remote system. Due to the lack of authentication information, tftpd will allow only publicly readable files to be accessed.Files may be written only if they already exist and are publicly writable. Note that this extends the concept of "public" to include all users on all hosts that can be reached through the network; This explains the behavior of the TFTP server, that is : It will upload a file if it only exists and are publicly writable. Some people are trying to load a file without these prerequisites and get an error.They think that this is an issue with the application or a bug in the TFTP version. But it is all written in the documentation. If you need a TFTP server to transfer files to, then use atftp (see my postInstalling TFTP server atftpd in Linux) Install the following packages sudo apt-get install xinetd tftpd tftp Create /etc/xinetd.d/tftp and add the following entry service tftp { protocol = udp port = 69 socket_type = dgram wait = yes user = nobody server = /usr/sbin/in.tftpd server_args = /tftpboot -s disable = no } Create a directory /tftpboot in root (as per server_args above) in above and change mode and owner sudo mkdir /tftpboot sudo chmod -R 777 /tftpboot sudo chown -R nobody /tftpboot Start the TFTP service sudo service xinetd stop sudo service xinetd start DOWNLOADING from the TFTP server Create a new file under/tftpboot touch /tftpboot/abcd.cfg Go to another folder and connect to the TFTP server and GET the files tftp 1
