Switch to the "TFTP Server" or "DHCP Server" tab page and click on "Settings" to set
the parameters as follows:
Figure 14-5
Settings
Under Linux
All current Linux distributions include DHCP and TFTP servers.
•
Install the corresponding packages according to the instructions provided for the rele-
vant distribution.
•
Configure the DHCP server by making the following settings in the /etc/dhcpd.conf
file:
subnet 192.168.134.0 netmask 255.255.255.0 {
range 192.168.134.100 192.168.134.119;
option routers 192.168.134.1;
option subnet mask 255.255.255.0;
option broadcast address 192.168.134.255;}
This example configuration provides 20 IP addresses (.100 to .119). It is assumed that the
DHCP server has the address 192.168.134.1 (settings for ISC DHCP 2.0).
The required TFTP server is configured in the following file: /etc/inetd.conf
•
In this file, insert the corresponding line or set the necessary parameters for the TFTP
service. (Directory for data: /tftpboot)
tftp dgram udp wait root /usr/sbin/in.tftpd -s /tftpboot/
The mGuard image files must be saved in the /tftpboot directory:
install.p7s, jffs2.img.p7s
•
If a major release upgrade of the firmware is carried out by flashing, the license file pur-
chased for the upgrade must also be stored here under the name licence.lic.
Make sure that this is the correct license file for the device (under "Management >> Up-
date" on the web interface).
•
Then restart the inetd process to apply the configuration changes.
•
When using a different mechanism, e.g., xinetd, please consult the relevant documen-
tation.
