Comtrol eCos - Manual (Page 111)

Chapter 1. Getting Started with RedBoot
• dynamic IP address allocation, using BOOTP
• TFTP service for file downloading
• DNS server for hostname lookups
Depending on the host system, these services may or may not be available or enabled by default. See your system
documentation for more details.
In particular, on Red Hat Linux, neither of these services will be configured out of the box. The following will
provide a limited explanation of how to set them up. These configuration setups must be done as
root on the host
or server machine.
Enable TFTP on Red Hat Linux 6.2
1. Ensure that you have the tftp-server RPM package installed. By default, this installs the TFTP server in a
disabled state. These steps will enable it:
2. Make sure that the following line is uncommented in the control file /etc/inetd.conf
tftp dgram udp wait root /usr/sbin/tcpd /usr/sbin/in.tftpd
3. If it was necessary to change the line in Step 2, then the inetd server must be restarted, which can be done via
the command:
# service inet reload
Enable TFTP on Red Hat Linux 7 (or newer)
1. Ensure that the xinetd RPM is installed.
2. Ensure that the tftp-server RPM is installed.
3. Enable TFTP by means of the following:
/sbin/chkconfig tftp on
Reload the xinetd configuration using the command:
/sbin/service xinetd reload
Create the directory /tftpboot using the command
mkdir /tftpboot
NOTE: Under Red Hat 7 you must address files by absolute pathnames, for example: /tftpboot/boot.img
not /boot.img , as you may have done with other implementations. On systems newer than Red Hat 7 (7.1 and
beyond), filenames are once again relative to the /tftpboot directory.
