       - Exceptions in Windows Firewall on TCP ports used in the program: the default is 5556 for client and 5555 for server.
       - Domain structure of the network. You can use RSend in a non-domain network with little loss of functionality (public groups usage, additional user/computer information from domain).

Program structure

RSendServer – provides a user registration, messaging, provides access to public (domain) and private groups, logging:
       - RSend.dll – shared library of functions for the server and the client.
       - RSendServer.exe – server executable.
       - RSendServer.exe.config – server config file.
       - RSend.dat – data file (automatically generated).
       - RSend.log – log file (automatically generated).

RSendClient – installed at the user:
       - RSend.dll – shared library of functions for the server and the client.
       - RSendClient.exe – client executable.
       - RSendClient.exe.config - client config file.
       - Lang.EN.config, Lang.RU.config - language config files.

RSendAlert – client command-line utility:
       - RSend.dll – shared library of functions for the server and the client.
       - RSendAlert.exe – utility file executable.
       - RSendAlert.exe.config - utility config file (the file name can be any).

Initial settings to run the program

1. RSendServer configuration is only required if you intend to use domain groups as RSend public groups. To do this, open a text editor "RSendServer.exe.config" and specify the names of the domain groups in the parameter "domainGroups".
2. RsendClient configuration. Open the "RSendClient.exe.config" in a text editor and change ip address of the server.
3. If you intend to use the attributes (for example, "Description") of domain objects "User", "Computer", "Group" as identifiers for RSend clients and public groups, set the parameters "domainShowUserDisplay", "domainShowHostDisplay" and "domainShowGroupDisplay" equal to "true" in the client and the server configuration files.
Examples: Standart mode Using attributes of domain objects

Tip. To exit RSendClient use the shortcut "Ctrl-Z". For more information about RSend configuration, operation, deployment in production environment and other issues please refer to Administrator Guide and User Guide.

Download rsend_2.4.9.zip (~61 kb, 27.10.2015, checked by Kaspersky Antivirus)

What's new in version 2.4.9:
    - Excluded parameters "domainGroupDescription" and "domainUserHostDescription" in the the server and the client configuration files. Instead, added new groups of parameters to add more flexibility of RSend depending on configuration of "Group", "User" and "Computer" objects in the domain:
    - Parameters "domainShow(Group, User, Host)Display" define whether to use the attributes of the domain objects "Group", "User" and "Computer" as identifiers of public groups, users, computers in RSend. Default is off ("false").
    - Parameters "domain(Group, User, Host)SearchAttribute" define the attributes to search for groups, users, computers in the domain. For example, "cn", "name", "sAMAccountName" and others. By default, used the attribute "name".
    - Parameters "domain(Group, User, Host)DisplayAttribute" define the attributes to identify public groups, users, computers in RSend. For example, "description", "displayName", "info" and others. By default, used the attribute "description".
