When deploying a NetScaler, Citrix recommend that you make these changes by default (https://support.citrix.com/article/CTX121149 ).
The Windows Scaling one was particularly useful on a customer site recently where connections over CAG would drop due to window size on the TCP stream not being negotiated with the ASA filrewall correctly. Enable windows scaling and the issue went right away.
So, I’m building a Global Server Load balancing solution based on NetScaler and I made a mistake entering in the IP address for the local GSLB site. I deleted the site and then went to create a new local site but whatever I do the site creation fails with the following error.
It turns out that, when the site is created NetScaler records the GSLB local site IP in its list of IP addresses. The RTM version of NetScaler 10.0 (build 54.6) has a bug in that it doesn’t delete this IP address.
Bacause a Global Site IP already exists, you cannot “add” another one. So, if you need to change the IP address used for the local GSLB site, you just need to delete the IP address recorded here and you are good to go. The other choice it to update the firmware to the current version as this bug is fixed in build 54.7.
Netscaler 10 has been released recently and something very odd happens when you log on to the console for the first time ….. you don’t get the initial configuration menu !
This sort of stops you being able to update the device IP address to configure it further. To get the configuration menu back, simply type in configns and press return.
By default when you install a NetScaler or AGEE the admin interface can only be connected to by HTTP. To configure the device to allow you to connect by HTTPS complete the following steps:
1) Connect to the devices configuration utility using a browser
2) Expand the Network node
3) Click on RPC
4) Select the NSIP (NetScaler admin IP Address)
5) Click Open
6) Tick the Secure check box
7) Click OK
