tftp claims: "no such file or directory"

This document (7023207) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 12 Service Pack 3 (SLES 12 SP3)
SUSE Linux Enterprise Server 12 Service Pack 2 (SLES 12 SP2)
SUSE Linux Enterprise Server 12 Service Pack 1 (SLES 12 SP1)
SUSE Linux Enterprise Server 11 Service Pack 4 (SLES 11 SP4)
SUSE Linux Enterprise Server 11 Service Pack 3 (SLES 11 SP3)

Situation

A TFTP Server is configured to serve pxelinux.0 for server installations and started, but when accessing a file "No such file or directory" is being reported even if the link to the file is not broken or the file present.

Filename: pxelinux.0
tftp://172.17.0.13/pxelinux.0... No such file or directory (http://ipxe.org/2d12603b)
mytftpserver:/srv/tftpboot # ls -l pxelinux.0
lrwxrwxrwx 1 root root 29 25. Jul 10:01 pxelinux.0 -> /srv/tftpboot/test/pxelinux.0
smt:/srv/tftpboot #

Resolution

Linking the file using a relative path solves the issue:

mytftpserver:/srv/tftpboot # ln -s test/pxelinux.0 pxelinux.0
mytftpserver:/srv/tftpboot # ls -l pxelinux.0
lrwxrwxrwx 1 root root 15 25. Jul 10:11 pxelinux.0 -> test/pxelinux.0
mytftpserver:/srv/tftpboot #

Cause

The TFTP runs per default in a chrooted environment, setting the entry directory to /srv/tftpboot as specified in
/etc/xinet.d/tftp:

service tftp
{
        socket_type             = dgram
        protocol                = udp
        wait                    = yes
        flags                   = IPv6 IPv4
        user                    = root
        server                  = /usr/sbin/in.tftpd
        server_args             = -u tftp -s /srv/tftpboot
        disable                 = no
}

Using absolute path names in links will end up in a "No such file or directoy" message as the absolute name cannot be found.
