Configuring a Citrix NetScaler for the First Time
Your new NetScaler is preconfigured with a default IP address (the NSIP) and associated subnet mask for management access. The default NSIP is 192.168.100.1 and the subnet mask (netmask) is 255.255.0.0. You can change these values to fit the addressing scheme for your network. For your initial configuration, you must also specify at least one MIP. Before saving your new configuration, you should change the administrator password.
If you are setting up two NetScaler appliances as a high availability pair, you configure one as primary and the other as secondary.
set ns config – ipaddress 10.102.29.60 – netmask 255.255.255.0
add ns ip 10.102.29.61 255.255.255.0 -type mip
add route 0.0.0.0 0.0.0.0 10.102.29.1
set system user nsroot administrator
save ns config
reboot
Configuring a High Availability Pair for the First Time
In one-arm configuration, both NS1 and NS2 and servers S1, S2, and S3 are connected to the switch.
In two-arm configuration, both NS1 and NS2 are connected to two switches. The servers S1, S2, and S3 are connected to the second switch. The traffic between client and the servers passes through either NS1 or NS2.
To set up a high availability environment, configure one NetScaler as primary and another as secondary. Perform the following tasks on each of the NetScalers:
- Add a node.
- Disable high availability monitoring for unused interfaces.
Configuring System Settings
To configure HTTP parameters by using the configuration utility
- In the navigation pane, expand System, and then click Settings.
- In the details pane, under Settings, click Change HTTP parameters.
- In the Configure HTTP parameters dialog box, specify values for some or all of the parameters that appear under the headings listed in the table above.
- Click OK.
To set the FTP port range by using the configuration utility
- In the left pane, expand System, and click Settings. The Settings page appears in the right pane.
- Under Settings, click Change Global System Settings. The Configure Global Settings dialog box appears.
- Under FTP Port Range, in the Start Port and End Port text boxes, type the lowest and highest port numbers, respectively, for the range you want to specify (for example, 5000 and 6000).
- Click OK.

To configure clock synchronization on your NetScaler
- Log on to the NetScaler command line and enter the shell command.
- At the shell prompt, copy the ntp.conf file from the /etc directory to the /nsconfig directory. If the file already exists in the /nsconfig directory, make sure that you remove the following entries from the ntp.conf file:
restrict localhost
restrict 127.0.0.2
These entries are required only if you want to run the device as a time server. However, this feature is not supported on the NetScaler.
- Edit /nsconfig/ntp.conf by typing the IP address for the desired NTP server under the file’s server and restrict entries.
- Create a file named rc.netscaler in the /nsconfig directory, if the file does not already exist in the directory.
- Edit /nsconfig/rc.netscaler by adding the following entry: /usr/sbin/ntpd -c /nsconfig/ntp.conf -l /var/log/ntpd.log &
This entry starts the ntpd service, checks the ntp.conf file, and logs messages in the /var/log directory.
Note: If the time difference between the NetScaler and the time server is more than 1000 sec, the ntpd service terminates with a message to the NetScaler log. To avoid this, you need to start ntpd with the -g option,which forcibly syncs the time. Add the following entry in /nsconfig/rc.netscaler:
/usr/sbin/ntpd -g -c /nsconfig/ntp.conf -l /var/log/ntpd.log &
If you do not want to forcibly sync the time when there is a large difference, you can set the date manually and then start ntpd again. You can check the time difference between the NetScaler and the time server by executing the following command in the shell:
ntpdate -q <IP address or domain name of the NTP server>
- Reboot the NetScaler to enable clock synchronization.
Note: If you want to start time synchronization before you restart the NetScaler, you can enter the
/usr/sbin/ntpd -c /nsconfig/ntp.conf -l /var/log/ ntpd.log &
command (which you added to the rc.netscaler file in step 5) at the shell prompt.
