9.2 TFTP Server Setup
In order to download the Linux kernel, the file system or the boot loader, it is
essential to have a TFTP server on the development computer. Also, the user
needs to have access rights for the /tftpboot directory in the root directory:
> su
Password
> mkdir /tftpboot
> chmod 777 /tftpboot
You have to install inetd and atftp via yast2 (S.U.S.E) before you can install a
TFTP server on the development PC. After the installation, make the
following entry in the /etc/inetd.conf:
<host-ip>:tftp dgram udp wait root /usr/sbin/in.tftpd -s /tftpboot
inetd starts automatically after a reboot or it can be started manually:
> /etc/init.d/inetd start
or restarted with
> /etc/init.d/inetd stop
> /etc/init.d/inetd start
