Clients fail to PXE boot using in.tftpd

This document (7016638) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Manager 2.1

Situation

When running tftp via /etc/xinetd.d/tftp instead of the preferred atftpd standalone daemon, clients fail to connect to the in.tftpd service. Changes to the config file are overwritten each time a cobber sync is executed:

susemanager:~ # cobbler sync
[...]
generating /etc/xinetd.d/tftp
[...]
*** TASK COMPLETE ***

Resolution

Edit /etc/cobbler/tftpd.template and remove the "-B 1380" and "-s" option. Resulting in:

susemanager:~ # cat /etc/cobbler/tftpd.template
# default: off
# description: The tftp server serves files using the trivial file transfer \
#       protocol. The tftp protocol is often used to boot diskless \
#       workstations, download configuration files to network-aware printers, \
#       and to start the installation process for some operating systems.
service tftp
{
        disable                 = no
        socket_type             = dgram
        protocol                = udp
        wait                    = yes
        user                    = $user
        server                  = $binary
#        server_args             = -B 1380 $args
        server_args             = -v /srv/tftpboot
        per_source              = 11
        cps                     = 100 2
        flags                   = IPv4
}

then run cobbler sync and restart xinetd.

As an alternate solution, edit /etc/cobbler/settings and change

manage_tftpd: 1

manage_tftpd: 0

save the settings and restart cobblerd (rccobblerd restart).
This will prevent any changes to the existing tftpd configuration in /etc/xinetd.d/tftp.

Cause

The options -B 1380 and -s are unknown to the in.tftpd binary.
