Tftpd Extra Quality
Tryg Lawson
I'm runnung Ubuntu 12.04 in a VirtualBox VM. I've installed the tftpd-hpa package. I'm using this to boot an embedded Linux system, and I've noticed that on first boot of my VM, it wouldn't work, but restarting the tftpd-hpa service made it work every time, until next boot.
Today, I ran a shell script from Texas Instruments that may have mucked with my tftpd configuration, and now I cannot get it to work at all. I'm able to connect, but transfers timeout, even to localhost (I also tried 127.0.0.1):
That note suggests a complex interaction of inetd and xinetd. Is it possible that somehow update-inetd was omitted from the latest install. Or conversely that everything else has been moved away from update-inetd to xinetd and tftpd did not get the message?
See the attached local.sh and pxesrv.gz. The latter contains /usr/sbin/in.tftpd and /lib/libwarp.so.0. As the method shown in booting the 4in1 iso, pxesrv.gz just needs to be added to the comma-separated initrd-list.
Neither Docker container running a tftpd bound to UDP/69 was able to work.I even erased all my disk contents and tried to do a completely fresh OS X install, thinking that some sort of buggy update caused some mess into my system.
Just to close this question, since I found no way to use tftpd as I did in the past in my daily basis, using Mac OS X, then I decided to solve it my on way and created a simple project which is based on Vagrant, VirtualBox and Docker that solved my all my needs:
I have a device that includes a Raspberry Pi 4 with the latest Raspberry Pi OS (Debian-based.) There is another device being tested that does a TFTP boot from the tftpd-hpa server running on the Pi. As long as I start the tftpd-hpa server manually after the Pi has booted everything works well.
systemd seems to be my nemesis. I have so far in my reading not discovered how to make the tftpd-hpa server start at boot time. I suspect it may be because the network may not be up and running when it tries to start.
I did try starting it in the same fashion as a previous question I had asked related to using a fixed Ethernet speed Howto Run Script At Boot Time To Set Ethernet Speed on Raspberry Pi 4 - Linux - nixCraft Linux/Unix Forum however, that does not work, the tftpd-hpa service never automatically starts.
I have made this change and my tftpd-hpa server now starts and runs properly at boot time. Not specifying the catch-all address seems to let the service start even if the network interface is not ready which was one of my suspicions.
I've tried all of the things I've been able to find, but none of them match my issue. I have a tftpd-hpa server and I'm trying to pull a file from it with u-boot. I get "file not found" regardless of what I do. What I've tried
tftpd comes in a variety of implementations; some may only be run under an inetd daemon, while others support standalone operation. The Linux iputils tftpd at time of writing only supports operation under an inetd daemon, so must be run that way. Other implementations may have a -l or --listen option to operate as a standalone daemon.
When you say Yast2, how I can add the -vvv (as TFTP_OPTIONS) in Yast2? Where?
Also, in.tftpd is for incoming traffic for tftp? So we will see only the incoming request and will not see what the tftp server is going to return for the client?
This Ansible role can configure a standalone TFTP server using thetftpd-hpa daemon. The TFTP server can be used to serve files forembedded devices or serve iPXE files from debops.ipxe role to otherhosts on the network, allowing for network boot and OS installation.
This appears to be the same issue as my report of failed PXE in bug #544377 "PXE Error: Only absolute filenames allowed" and is caused by the tftpd-hpa daemon not being started with --secure (-s) mode.
