Configuring NTP Server in HP Procurve Switches

Time is important for you to check logs.
This time I'd like to show you how to configure NTP Server in HP Procurve Switches.
HP Switches are only support less secure SNTP instead of NTP.

OK. Let's Configure!

Login to your switch with console/terminal and type following commands for your sntp server configuration.

configure terminal
timesync sntp


sntp unicast (Use this command if you want to use only one NTP server)
(or)
sntp broadcast
(Use this command if you want to use more than one NTP server)

sntp server priority 1 218.186.3.36
(or)
sntp server  218.186.3.36

(These above two commands are working on different model.
Some model work first command and some model work second command.
Please take note that you can configure maximum 3 NTP server for your switch.
In my example, I use NTP server for Singapore)


time timezone +480 (Formula for this command is GMT+Regional Time in Minute. I use Singapore Time and GMT+8. 8 hours in minute is 480. So result is GMT+480)

Once you done above all commands, use below command to check NTP Server setting.

show sntp
(or)
show sntp statistics
(This command is not working on some switch model)

If NTP server setting are correct, check the time with command "show time".
If Time is showing as expected ,save the configuration with "write memory" command.
Logout from switch then.
If NTP server setting is not correct as what you expected, check all your configuration again.

Hope this post help you on configuratre the SNTP for your switch.

Have a good time.

Fortigate guide for Begineer - 6

I would like to explaine how to troubleshoot the Fortigate Unit configured by Transparent Mode in step by step this time. Let's assume, you have one Fortigate Unit that configured as Transparent Mode. But devices from Internal/Private Network unable to access Internet/Public Network through your Fortigate Unit. OK. Let's troubleshoot with following steps, 1) Check the physical network connections between the network and the FortiGate unit, and between the FortiGate unit and the Internet. 2) Check the router and ISP-supplied equipment to make sure it is operating correctly. 3) Verify that you can connect to the internal interface by connecting to the management IP address of the FortiGate unit from the Internal network. From the internal network, attempt to ping the management IP address. If you cannot connect to the internal interface, verify the IP configuration of the PC and make sure the cables are connected and all switches and other devices on the network are powered on a

Solving the "A general system error occured:Invalid fault" error in vSphere 4

Below error was come out when you try to migrate VM to other host for some reason. Below error was come out when you try to edit VM setting. Below error was come out when you power on the VM. How to solve those error? Here is how I resolve the error! Login to the Host that errored VM exist by using Terminal or Direct Console. Enter below command and press enter. services.sh restart Wait until all VMware Services are restarted. After that try to Power On/Edit Settings or Migrate the errored VM and you will see all you can do without any error pop-up. This kind of errors can occur if you shutdown/restart VM unproperly or shutdown/restart the Host unproperly that VM exist. You can check log file deeply if you willing to know precisely on this. May you all be happy. (Be knowledgeable, pass it on then)

Why do we need network virtualization?

We need to think about Server Virtualization first if we want to talk about Network Virtualization. In the era of cloud computing, servers are virtualized and used in Data Centers. We are facing a lot of problem when we virtualized our Servers, 1) Routing and Switching Problem Routing become the issue when we create Virtual Switch and VLANs according to production requirement. Network Team might need some time to change on their end to meet with Server Virtualization Team changes on their end. ၂) Firewall Services Physical Firewall are difficult to manage due to the large number of rules needed to satisfy business requirements. New applications, new projects, and new networks all come with potential security requirements, which impact centralized firewall management. ၃) Load Balancing Let's say your company deploys a new physical load balancer for each tenant, resulting in increased capital expenditures. Once a tenant reaches their maximum capacity, it ca
