SCO OpenServer runtime products

Products listed in this section are included on the SCO OpenServer System CD-ROM:


Apache Web Server
The Apache Web Server has been integrated into SCO OpenServer, replacing the Netscape FastTrack server. SCO OpenServer includes the /etc/apache startup script, with options to enable/disable and start/stop the Apache web service.

The Java Runtime Environment is now installed by default with SCO OpenServer. Previously, the JRE was only available from the UDK CD-ROM.

OpenSSH
OpenSSH, a suite of network connectivity tools that encrypts all traffic to eliminate eavesdropping, connection hijacking, and other network-level attacks, is now included with SCO OpenServer Release 5.0.7. The OpenSSH suite includes the ssh(1) program (replacing rlogin and telnet), scp(1) (replacing rcp), and sftp(1) (replacing ftp). For more information on these OpenSSH tools, see the Section 1 manual pages or the following URL: www.openssh.org/manual.html.

OpenSSL
OpenSSL, an Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols, as well as a general purpose cryptography library, is also included with SCO OpenServer Release 5.0.7. A user-level command for performing a variety of cryptographic functions, openssl, is also provided. For more information on OpenSSL, see the OpenSSL manual pages, including ssl(3) and openssl(1), or see the following URL: www.openssl.org.

Perl
Perl has been updated to version 5.8.0, which includes enhanced Unicode and threads support, the new I/O subsystem called PerlIO, and many bug fixes. For more details, see the following URL: www.perl.org.

sendmail
sendmail has been updated to version 8.11.0. Highlights of this version include:

Also in this release, the sendmail.cf file has been updated to version 9 to provide better anti-spam capabilities. An M4 configuration file has also been included.

See ``sendmail administration'' for more information.

Volution Manager Client
Caldera Volution(TM) Manager is a web-based systems management product that runs on Caldera OpenLinux® 3.1.1 servers. Volution Manager can manage SCO OpenServer systems through the use of Volution Manager clients. The Volution Manager client is included with SCO OpenServer Release 5.0.7 and is automatically installed as part of the base operating system. For information on enabling the Volution Manager client and using Volution Manager to perform a variety of administration tasks on your SCO OpenServer system, see ``Managing SCO OpenServer systems with Caldera Volution Manager'' and ``Managing your system with Caldera Volution Manager''.

Samba File and Print Server Release 2.2.6
SCO OpenServer Release 5.0.7 introduces support for Samba File and Print Server Release 2.2.6, a suite of networking products based on Open Source technologies that implement the SMB/CIFS (Server Message Block/Common Internet File System) protocols on UNIX and Linux platforms. This release of Samba provides:

For more information about Samba features and administration, see:


NOTE: SCO also offers SCO Advanced File and Print Server (Advanced Server), a UNIX-based network operating system that interoperates with systems running Microsoft® Windows servers and Workstation. Although Advanced Server and Samba are comparable, the former can be administered from Windows systems using Windows tools, while Samba administrative tools use UNIX and web-based conventions. The two products also implement authentication and security management differently, although authentication is compatible. Consult your SCO representative to determine which product is most appropriate for you.


SCO OpenServer Development System

The SCO OpenServer Release 5.0.7 Development System has been updated to improve multibyte and wide-character support. Additionally, the ability to scan and print 64-bit integers has been added. (Note that only the GNU C compiler supports 64-bit integers.)
