Bug Description

Binary package hint: tftpd

I'm using tftpd to make a kernel image available for an embedded device. The device uses the U-Boot bootloader, which is configured to load the kernel image from a server.
On the server, I run a tftp daemon under KUbuntu. With in.tftpd from the tftpd package, this doesn't work. Messages in syslog show that tftpd recognizes the request correctly, but then terminates the connection without any visible reason. Installing the package tftpd-hal instead of tftpd solves the problem.

After some googling, I found out that the problem is already known, but it seems nobody ever filed a bug report against that package, so here it is.

First I need to correct a typo: A "tftpd-hal" package doesn't exist, I meant tftpd-hpa.

I observed the bug under Kubuntu 6.06.1, but it seems to be a general problem of tftpd which can also be seen under other distributions. Problems are described e.g. here:

http://www.sigsegv.cx/diskless-2.html

and here (in German):

http://www.bsdforen.de/showthread.php?t=18129

Some postings I read suggest the problem is caused by tftpd trying to setup an IPv6 connection, which cannot be handled by U-Boot. I don't know if this is true or not. But several web pages I found say that tftpd-hpa is the only tftp server that is actually working in their application.

I have seen a problem with tftpd package as well. This is on 7.04 feisty.
The client makes a request with tsize = 0 but tftpd server reports tsize is missing.
Changed to tftpd-hpa and its fine.

To work around the IPv6 connection bug, install xinetd or similar and set up tftpd as described here: http://www.davidsudjiman.info/?p=93

But instead alter udp to udp4 as below

service tftp
{
protocol = udp4
port = 69
socket_type = dgram
wait = yes
user = nobody
server = /usr/sbin/in.tftpd
server_args = /tftpboot
disable = no
}

Still not working in 10.04, three years later. If tftp only works with xinetd and doesn't work with openbsd-inetd, shouldn't its dependencies be adjusted accordingly? On Lucid, installing tftp installs openbsd-inetd which doesn't work at all.
