RedCheck licenses are based on the number of targets you want to scan from a single RedCheck console.
Every license has an expiration date; the default license duration is one year, which can be renewed. Technical support, security content updates, and software updates are available for clients with valid licenses.
While installing RedCheck, you need a 32-bit license key for activation (available on RedCheck official letterhead). Once the license is activated, you will see hosts available for scanning in the console. The number of scanned hosts is set in your license.
If you move your console to another computer, your activation key might become unavailable. In this case, please contact technical support team for details about how to reactivate the license.
If you buy an additional license to extend the number of hosts available for scanning, these hosts will appear in the console after the next content synchronization.
Application Server Security Audit module requires a separate license. A single license is provided for one IP address with installed applications (web servers). There are limitations: there should be no more than two web servers (two DNS names) on the same IP address.
To buy a license, please contact ALTEX-SOFT sales department:

7. Click CHECK NAMES and then OK
8. Click CREATE

If you created a REDCHECK_ADMINS local group and added a user thereto, then log out or reboot once RedCheck is installed.

If a network has a domain structure and several accounts are used to run RedCheck management console and scan target hosts, then each account should be within a REDCHECK_ADMINS global security group. To create a REDCHECK_ADMINS global group:

1. Open an ACTIVE DIRECTORY – USERS AND COMPUTERS snap-in by using Win+R keyboard combination to open RUN dialog box, entering dsa.msc in the OPEN field there and then clicking OK.
2. In the snap-in tree, expand your domain node and go to an item where the global group will be created. Right-click this item and select CREATE and then GROUP in the context menu
3. In the pop-upped dialog box NEW OBJECT – GROUP, enter REDCHECK_ADMINS in the GROUP NAME field and select GLOBAL in GROUP TYPE section.
4. Add a user account who will start console/scanning
5. Having filled in all mandatory fields, click OK

If you created a global group and added a user thereto, then apply the changes to a domain controller and on all client machines once RedCheck is installed.
All local REDCHECK_ADMINS groups should be deleted.

Open TCP/8732 for correct connection between the RedCheck console and an agent. If you use the default Microsoft Windows firewall, follow the instructions given below for Microsoft Windows 7:
1) Open Windows Firewall. Click Start — Control Panel. Type «firewall» in the search box, and click Windows Firewall in the search results
2) On the left, select «Advanced settings». Click on «Windows Firewall with Advanced Security», and in the right panel click New Rule
3) Select Port rule type and click Next
4) Specify TCP type and 8732 local port and click Next. Specify profile according to your network configuration

For agentless scanning, the scanner should be connected to Windows Management Instrumentation (WMI) of a scanned node, with settings being done locally, on the node, or centrally, using Windows Group Policies as well as other network administration tools. For local settings of the scanned node, proceed as follows:

1) Open WINDOWS FIREWALL by clicking START button and then CONTROL PANEL, entering ‘firewall’ in a search line and selecting WINDOWS FIREWALL
3) Scroll down in the ALLOWED PROGRAMS AND FEATURES list and tick a box in WINDOWS MANAGEMENT INSTRUMENTATION (WMI) line depending on the network architecture: domain or work group. Click ОК.

Linux, Cisco IOS and VMware are subject to agentless scanning, with SSH protocol (port 22 by default) being used as a transport.

Double-check the following:
1. Port 8732 has been opened on a client machine and is not blocked by either firewall or other security tools
2. WMI has been configured
3. RedCheck_Admins group has been configured
4. The machine is available via a command line and Ping function
5. The agent utility is running on the remote machine

For Linux scanning

1. Install OpenSSH Server package
2. Open a firewall port (port 22 by default)
3. Allow connection to certain SSH users
To configure SSH, go to /etc/ssh/sshd_config
To allow an SSH connection on behalf of the Root user, add the following:
PermitRootLogin yes
Once all necessary configurations are done, reboot: service ssh restart

For VMware scanning

VMware ESXi Server and VMware Vcenter Server should be scanned over SSH protocol v. 2 or higher, with SFTP module being on.
To configure SSH:
1. Activate SSH via ESXi host console (Option 1)
Go to host settings and select ENABLE SSH on TROUBLESHOOTING OPTIONS tab

2. Activate SSH via vSphere client (Option 2)

For Cisco IOS scanning

The scanning uses SSH protocol (port 22 by default) as a transport.
To activate SSH in Cisco IOS, take the following six mandatory steps:
1. Set a device name using a HOSTNAME command
(config)#hostname sw01

2. Set a user name and password
(config)#username Admin1 secret 5 $1$ukk…

3. Configure a DNS domain using an IP DOMAIN-NAME command
(config)#ip domain-name

4. Generate an RSA key to activate SSH on the device using (config)#crypto key generate rsa
Verify the key using #show crypto key mypubkey rsa
If the key is available, you will see its name and generation date:
% Key pair was generated at: 00:07:18 YEKT Jul 31 2014
Key name:
Usage: Encryption Key
Key Data:
xxxxxxxx xxxxxxxx xxxxxxxx …

5. Allow a virtual terminal to support SSH
(config)#line vty 0 4
(config-line)#transport input ssh
(config-line)#login local (if aaa new-model is not used in step 2)

6. Set v.2 to be used
(config)#ip ssh version 2

Make sure a super user account (root by default) is active and remote access over SSH is allowed.
To activate the super user root account, change its password: passwd root
To allow remote access over SSH for the super user root account, configure an SSH server by editing a configuration file and adding the following directive: PermitRootLogin yes. The default name of an SSH server configuration file is /etc/ssh/sshd_config. The SSH server configuration file may already contain PermitRootLogin directive. In this case, simply change the directive’s value to YES. If a system’s security policy does not allow the use of a super user account required to run the scanning, opt for user accounts of other types.

1. The link to download the updated distribution kit will be provided to you in your account on customer support portal after submitting the request.
2. Run the installer (if the software is already deployed) and follow the instructions
3. Enjoy the upgraded RedCheck once the installer finishes its work

The complete reinstallation of the scanner is not needed.

The most common reasons for this problem are incorrect account configuration and scanning service being down. For account configuration, see the relevant section in the admin guide. Configure in line with the network topology and restart the scanning service RedCheckSVR.

Make sure the pinging account has been configured in line with the admin guide and network topology. Check to be sure the agent is installed and active on a remote machine.

Make sure the WMI-related system settings are OK and there is no blocking by personal firewalls or antivirus applications. Note that a pinging account must have admin privileges.

Install Nmap.exe and specify a path by clicking Alt+S and going to NMAP COMPONENT tab.
