WASP - Maximum number of registrations reached

You need to make a change on the server to resolve this.

On the computer with your InventoryControl database:

Click Start > Run.  Type 'regedit' in the blank and click Ok.  Click the + next to HKEY_LOCAL_MACHINE > SOFTWARE > Wasp Technologies > Wasp License Manager > Products for 32 bit Windows, or HKEY_LOCAL_MACHINE > SOFTWARE > Wow6432Node > Wasp Technologies > Wasp License Manager > Products for 64 bit Windows.

You'll have folders under Products named ID70 and ID79.  Check both of these for entries on the right that say "Client1" or "Client2" etc.   The data for these keys will be the serial number in folder ID70 or activation code in ID79, followed by the client's machine name. Delete the keys for the machines that are no longer in use. 

If you are seeing multiple keys for the same client machine, check the license to see if there are spaces in the license, i.e. "0679 107..." If that is the case, delete those keys, then go to the client machine, run regedit, and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Wasp Technologies\InventoryControl\Options, or HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Wasp Technologies\InventoryControl\Options for 64 bit Windows. Right click License and select Modify, then remove the spaces from the license number.

Axis Camera Update Firmware - FTP

1. You must be at the command prompt and in the directory that contains the upgrade file. Example: C:\Axis\213\4_02>
2. From the command prompt, open an FTP connection to the unit you wish to upgrade. (Do not use a "Windows" based FTP-program to do this, use only command line FTP programs!)
3. Log in as root. The default password for the root user is "pass", unless this has been changed by the user. You must be logged in as the root user to upgrade the unit.
4. Change to binary transfer mode by typing "bin" and press enter. Type "hash" and press enter. (This will allow you to see how the upgrade progresses)
5. Type the command "put XXX.bin flash" where XXX.bin is the name of the upgrade file you downloaded (and maybe decompressed) from our site. 
6. Wait for the flash load to complete, which may take 1-10 minutes.

Adding a TCP/IP Route to the Windows Routing Table

Syntax:

route ADD xxx.xxx.xxx.xxx MASK xxx.xxx.xxx.xxx  xxx.xxx.xxx.xxx
Means:
route ADD “network” MASK “subnet mask”  “gateway ip”

 route ADD 10.10.10.0 MASK 255.255.255.0 192.168.1.12

options :
ADD
DELETE

How to Configure VPN on Sonicwall TZ 200 and TZ 215

1. Login to sonicwall 
2. Click on Network and select WAN (by default X1) configure

 

3. Next, navigate to SSL VPN > server settings. 

Click on WAN interface link to change the red dot to green. This enables the SSL VPN feature.  

SSL VPN Server Settings :

 

In the SSL Server VPN settings, you may want to change the default port to 443 if the VPN users travel frequently and find themselves behind highly restrictive firewalls that block outbound access by port. Port 443 is usually not blocked by even the most restrictive firewalls. 

If you decide to do this, keep in mind that you will need to change the Sonicwall management port to something other than the default port 443. Do this under the system > administration menu. You will also need to double check that port 443 is not being used for other services such as an Exchange/OWA HTTPS connection. 

In SSL VPN > Portal Settings you can customize the message that appears to VPN users. Just edit the HTML text to create custom messages or to link custom logos. 

Under Client Settings, follow these instructions: 

 

Interface: Select your LAN Interface, by default X0 

NetExtender IP: SSL VPN will not use the DHCP address pool from either the firewall or from a server on your network . For this reason, you must specify a range of usable IP addresses for the VPN client. Make sure the address pool is outside the scope of your DHCP server's pool. 

DNS Server: Configure your internal DNS server IP address 

Domain: Configure the internal domain 

WINS: If you use WINS, enter the IP address of your WINS server. 

Default Session Timeout: I like to increase it from the default to avoid constant disconnects. 

Enable Web/SSH Management over VPN: Enabled if you want VPN access to manage the Sonicwall device. 

Exit Client after Disconnect: Enabled will shut down the NetExtender client program. 

Uninstall Client after Exit: If enabled will uninstall client software after disconnect (not recommended in most cases). 

Lastly, in the Client Routes, click on Add Client Routes and select LAN Subnet to allow the VPN client access to the LAN subnet. 

Now that you have completed the SSL VPN setup, the two remaining things to do are:

1. Add SSL VPN users
2. Install NetExtender and connect to the VPN

Once you have finished, log in using using HTTPS and either the IP address and port or URL and port to access the Virtual Office VPN connect site.

RAID 0, RAID 1, RAID 5, RAID 10 Explained with Diagrams

RAID stands for Redundant Array of Inexpensive (Independent) Disks.
On most situations you will be using one of the following four levels of RAIDs.

• RAID 0
• RAID 1
• RAID 5
• RAID 10 (also known as RAID 1+0)

This article explains the main difference between these raid levels along with an easy to understand diagram.
In all the diagrams mentioned below:

• A, B, C, D, E and F – represents blocks
• p1, p2, and p3 – represents parity

 

RAID LEVEL 0

image

Following are the key points to remember for RAID level 0.

• Minimum 2 disks.
• Excellent performance ( as blocks are striped ).
• No redundancy ( no mirror, no parity ).
• Don’t use this for any critical system.

 

RAID LEVEL 1

Following are the key points to remember for RAID level 1.

• Minimum 2 disks.
• Good performance ( no striping. no parity ).
• Excellent redundancy ( as blocks are mirrored ).

 

RAID LEVEL 5

 Following are the key points to remember for RAID level 5.

• Minimum 3 disks.
• Good performance ( as blocks are striped ).
• Good redundancy ( distributed parity ).
• Best cost effective option providing both performance and redundancy. Use this for DB that is heavily read oriented. Write operations will be slow.

 

RAID LEVEL 10

Following are the key points to remember for RAID level 10.

• Minimum 4 disks.
• This is also called as “stripe of mirrors”
• Excellent redundancy ( as blocks are mirrored )
• Excellent performance ( as blocks are striped )
• If you can afford the dollar, this is the BEST option for any mission critical applications (especially databases).
