ATTENTION

How to enable/disable telnet/ftp server

a.Edit the file ‘/etc/inetd.conf’

Example (default enable):

discard dgram udp wait root /bin/discard discard stream tcp nowait root /bin/discard telnet stream tcp nowait root /bin/telnetd ftp stream tcp nowait root /bin/ftpd -l

b.Disable the daemon by typing ‘#’ in front of the first character of the row.

How to enable/disable /etc/inittab www server

a.Edit the file ‘/etc/inittab’

b.Disable the www service by typing “#” in front of the first character of the row.

How to enable Network Time Protocol

ntpdate is a time adjusting client utility. UC-7110 plays the role of Time client, and sends requests to the Network Time Server to request the correct time.

Set the time server address for adjusting the system time with the command:

/>ntpdate ntp_server_ip

Save the system time to the hardware’s real time clock, with the command:

/>hwclock --systohc

Visit http://www.ntp/org for a recommended public NTP server list.

How to update the system time periodically via Network Time Protocol

1.Create a shell script file that includes the following description.

#!/bin/sh

ntpdate ntp_server_ip hwclock –systohc

sleep 100 Å The min time is 100ms.

2.Save and change this shell script to run-able by typing chmod 755 <shell-script_name>

Edit the file ‘/etc/inittab’ by adding the following line:

ntp: unkown: /directory/<shell_script_name>
