Continuing on the post last week when we discussed the NetScaler user interface that provides an excellent way to troubleshoot and diagnose the NetScaler system (/ blogs / 2012 / 01/19 / how easy it-is-diagnosetroubleshoot NetScaler /). This week we will focus on the "Utilities" section of the diagnostic page
batch configuration :. This utility provides a way to execute batch configuration on NetScaler. You can specify the command file from your client system or from the NetScaler appliance. The generated output can be pushed to a different file on the given path. You also get to see the output in the same window and you can record the output on your desktop
Ping / ping6 :. are the utilities to run Ping tool for IPv4 and IPv6, respectively. When you use this command-line tool, you realize how useful options are there. The simple " Count " option may limit the number of times of numbers you want to run ping. The " Timeout " provides data to ping the time to get out in case of failure. the " interval " option is the waiting time in seconds before sending the next request. " Interface " would you allow to choose the interface to use for the ping. " pattern " is where you fill in the hexadecimal model that goes into the data part. " Size " limit the amount of data sent with ping packet. " source IP address " allows you to spoof the source IP address for the ping packet to be sent. you can see out there or save it in the file and
TraceRoute / traceroute6 :. are the utilities to run the TraceRoute tool in IPv4 and IPv6 mode respectively. Even as ping, with TraceRoute you can see several important options in the feed section. " Packet Length " controls the packet length and default to 44 bytes and can go max 32768 bytes of data. " Minimum TTL " and " maximum TTL " are the minimum and maximum values used for outgoing probe packets. " Protocol " allows you to specify the UDP or ICMP protocol name. " Port Number " is the basic port number used in probes. " Number of requests " is the number of times it will query by jumping. " Source IP address " you can specify and the possible use spoofed addresses as source for outbound requests. " Type of Service " option to specify the type of service in outbound requests. " Waiting time " is the waiting time in seconds for a response to a query. Then there are several boolean options you can choose to work with. You can also choose to save the output to a local file
Command Line Interface :. This is pretty interesting one that provides the CLI you can work on as a regular CLI. This is the context of the user interface and you have all the RBAC policies in this CLI access mode based on the user who is logged into the GUI. You can take all actions and execute all the commands you would on the regular CLI
Unzip File :. this tool will allow you to unzip a file on NetScaler
Start DST file synchronization :. This is very useful utility that allows you to synchronize files between primary and secondary. It provides you multiple file synchronization modes:
- Everything But licenses and rc.conf
- Does any sync between leaving the license directory and rc.conf file
- Bookmarks
- only synchronizes bookmarks saved SSLVPN fashion
- SSL certificate and key
- syncs all in / nsconfig / ssl / directory
- EdgeSight scripts monitoring
- syncs the ES4NS scripts
- imported Objects XML
- syncs items imported as schema and WSDL
- Licenses and rc.conf
- synchronization license files and rc.conf
- everything including licenses and rc.conf
- syncs everything through in HA pair
These are the tools you want to use from day to day functioning. More to come in the next blog ...
