SNF Client/Server *nix

This product is for use in a *nix environment where SNF will be integrated through scripting (such as a postfix filter) or as a kind of command line scanning utility. This product is also useful if you will be running SNFServer as a daemon and issuing XCI scan requests.

You can download this package from our Products page.

This distribution includes:

• SNFServer.exe - Source for *nix systems. (SNF Server Application)
• SNFClient.exe - Source for *nix systems. (SNF Client Application)
• snf2check.exe - Source for *nix systems. (SNF Rulebase Authenticator)
• getRulebase - Bash script (uses wget, gzip, and snf2check.exe).
• snfctrl - Bash script for launching SNFServer as a daemon.

SNFServer.exe provides a high performance, multi-threaded implementation of the SNFMulti anti-spam engine coupled to a TCP (locahlost) server that accepts XCI requests. SNFServer.exe can be run at the command line for testing; it can be launched as a child process as part of a larger filtering system; or it can be run as a service using srvany, XYNTservice, or any similar utility.

SNFClient.exe provides a command line interface to SNFServer.exe by translating command line scan requests to XCI requests and interpreting the result. SNF scan result codes can be retrieved as the %errorlevel% in scripts or directly by the calling program. Declude, eWall, and mxGuard are examples of message filtering systems that typically call SNFClient.exe to scan messages.

snf2check.exe is a command line utility that tests SNF rulebase files for authenticity and integrity.

getRulebase.cmd provides a rulebase update mechanism using the open source utilities wget (for retreiving the rulebase) and gzip (for decompressing the rulebase file). The script is designed for use with SNF's update-script feature to provide up-to-the-minute filtering rules automatically.

snfcrtl is an example bash script for launching SNFServer.exe as a daemon.

Note: Although this source distribution is most commonly used on *nix systems it is also the exact same source code we use to compile these programs for win* systems using MinGW!
