Troubleshooting the 4200 Series Appliance
The error occurs when ntpdate is running while ntpd is running. The defect is that
Note
MainApp should shut ntpd down every time the NTP configuration is changed so
that ntpdate can be run to immediately synchronize with the NTP server.
To correct the NTP reconfiguration defect, follow these steps:
Log in to the sensor service account.
Step 1
Step 2 Su to root using the service account password.
bash-2.05a$ su root
Password:
Type the following command:
Step 3
[root@sensor]# killall -INT ntpd
Step 4 Log out of the service account.
Log in to the sensor CLI.
Step 5
Enter configuration mode:
Step 6
sensor# configure terminal
Enter service Host mode:
Step 7
sensor(config)# service Host
Step 8 Enter time parameters submode:
sensor(config-Host)# timeParams
Set up NTP (NTP server IP address, key ID, and key value):
Step 9
sensor(config-Host-tim)# ntpServers ipAddress
sensor(config-Host-tim-ntp)# keyid
sensor(config-Host-tim-ntp)# keyvalue
Here is an example of an NTP configuration:
sensor(config-Host-tim)# ntpServers ipAddress 10.87.126.52
sensor(config-Host-tim-ntp)# keyid 10
sensor(config-Host-tim-ntp)# keyvalue cisco
