Table of Contents
5.1. Why using a TFTP server
It provides config files, bootstraps for PXE client.
5.2. How to install a TFTP server ?
In Mandrake Linux 8.1 the package is : tftp-server-0.17-7mdk. By default on Mandrake Linux 8.x, tftp server is launched from the xinetd server :
service xinetd start
The TFTP server sources can be downloaded here [6]5.3. Xinetd Options
5.3.1. Disable
5.3.2. User
5.3.3. Server
5.3.4. Server_args
5.3.4.1. Block Size option
By default the tftp server negotiates with the client on the block size. Some tftp client are not able to handle the negotiation process. In this case you must tell the tftp server not to negotiate the block size using the -r blksize option.
5.3.4.2. Size ahead of time option
By default the tftp server negotiates with the client on the size ahead of time. Some tftp client are not able to handle the negotiation process. You can also prevent the tftp server to start the negotation on the timeout using the -r blksize option
5.3.4.3. Timeout option
By default the tftp server negotiates with the client on the timeout. Some tftp clients are not able to handle the negotiation process. You can disable the negotation on the size ahead of time using the -r tsize option.
5.3.4.4. Chrooting option
The -s /tftboot specify that our tftp server is chrooted to the tftpboot directory. So be careful when using the filename option in the file dhcpd.conf. It must be set to :
filename "/PXEClient/pxelinux.0"
and not to :filename "/tftpboot/PXEClient/pxelinux.0"
5.4. Sample tftpd file
service tftp
{
disable = no
socket_type = dgram
protocol = udp
instances = 2
wait = yes
user = nobody
server = /usr/sbin/in.tftpd
# server_args = -r blksize -r tsize -r timeout -v -v -s /tftpboot
server_args = -v -v -s /tftpboot
}
