New and updated products and components

The following new and updated products and components are included with SCO OpenServer Release 5.0.7:

• ``SCO OpenServer runtime products''

• ``SCO OpenServer Optional Services''

• ``SCO OpenServer Development System''

• ``Additional Development Environments and Tools''

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. This version of Apache includes support for XML, PHP, ASP, and other popular Apache technologies, such as mod_perl. You can access the Apache documentation from the Internet Services link on the DocView home page.

BIND

BIND has been updated to version 8.2.5, and all of the security patches from version 8.2.6 have been applied. See ``Configuring the Domain Name Service'' for more information.

Java Runtime Environment

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:

• Added vigilance for set*uid(), setgid(), setgroups(), initgroups(), and chroot() calls.

• Outgoing (client-side) SMTP Authentication mechanisms limited to those specified in AuthMechanisms to prevent information leakage.

• Safe file checks now backtrack through symbolic links. This ensures that the files cannot be compromised due to poor permissions on the parent directories of the symbolic link target.

• Only root, TrustedUser, and users in class t can rebuild the alias map.

• All file descriptors (besides stdin, stdout, and stderr) are closed before restarting sendmail.

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.

Squid Web Proxy Cache

SCO OpenServer Release 5.0.7 now includes Squid, the high performance proxy cache for Web clients. This product is not installed by default. After you install Squid, you can access the documentation from the Internet Services link on the DocView home page.

Volution Manager Client

Caldera Volution 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''.

Web Browsers

SCO OpenServer Release 5.0.7 provides two new web browsers:

• the graphical Mozilla web browser

• the character-based Lynx web browser

For more information on using these products, see mozilla(1) and the following URL: lynx.browser.org.

SCO OpenServer Optional Services

Products listed in this section are included on the SCO OpenServer Optional Services CD-ROM and must be installed separately. New Optional Services products include:

NeTraverse Merge 5.3

NeTraverse Merge 5.3 is the successor to SCO Merge 5.1. New and enhanced features in this new release include:

• Support for Microsoft Windows ME, Windows 98 Second Edition, as well as DOS applications.

• Support for Windows VNET Networking on SCO OpenServer systems, allowing Merge users, UNIX users, and native Windows users to share files and print facilities via Windows Network Neighborhood.

• Audio playback support (using third-party device drivers).

• Zoomless installation of Windows. A UNIX console is not required during the Windows installation.

• Support for web browsers such was Microsoft Internet Explorer 5 and 6, as well as Netscape Communicator versions 4.x, 6.x, and 7. A wide variety of personal and office productivity tools such as Microsoft Office 2000 and Outlook are also supported.

• Automatic creation of D: drive for user data.

• Available Windows memory increased to 128MB.

Once Merge is installed, you can access the documentation from the Windows and NetWare Connectivity link on the DocView home page.

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:

• file and print services to Windows, UNIX, and Linux clients

• authentication, authorization, and name resolution services

• service announcement (browsing)

• updated SWAT (Samba Web Administration Tool) wizard for remote administration

• numerous enhancements and bug fixes over previous releases

For more information about Samba features and administration, see:

• the /info/samba/readme.html file on the Optional Services CD-ROM

• the Samba documentation, available from the Windows and NetWare Connectivity link on the DocView home page after Samba is installed

---

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.
