Red Hat Linux 7.1 Release Notes

This document describes features that are new to Red Hat Linux 7.1, but may
not have been available prior to our documentation being finalized.  For
the very latest information, please read the RELEASE-NOTES file on the Red
Hat Linux CD #1.

Last-Minute Changes

    o The Oracle installation program (versions 8.1.7, 8.1.6, and possibly
      others) does not work properly with glibc 2.2 and above.  The problem
      is that it is linking object files compiled against different glibc
      (binary compatibility is ensured only for linked executables and
      shared libraries through symbol versioning).  You may work around
      this by installing the Red Hat Linux 6.2 compatibility packages
      (compat-egcs, compat-glibc and compat-libs) and issuing the following
      commands before running the Oracle installer:

        export LD_ASSUME_KERNEL=2.2.5
        . /usr/i386-glibc21-linux/bin/i386-glibc21-linux-env.sh

      The second line exports environment variables which will cause gcc
      and ld to look for glibc 2.1.3 compatibility headers and libraries.

    o Reminder regarding NFS, FTP, or HTTP installations -- Because the Red
      Hat Linux 7.1 installation program is capable of installing Red Hat
      Linux from multiple CD-ROMs, if you intend to support NFS, FTP, or
      HTTP installations it is no longer possible to simply mount a single
      Red Hat Linux CD-ROM, and install from it.

      Instead, you must copy the RedHat directory from each CD-ROM
      comprising Red Hat Linux 7.1 onto a disk drive:

        - Insert CD 1
          mount /dev/cdrom /mnt/cdrom
          cp -var /mnt/cdrom/RedHat /location/of/disk/space
          umount /mnt/cdrom

        - Insert CD 2
          mount /dev/cdrom /mnt/cdrom
          cp -var /mnt/cdrom/RedHat /location/of/disk/space
          umount /mnt/cdrom

      You must then make /location/of/disk/space accessible to the
      installation program (for example, exporting it for NFS

        - Export /location/of/disk/space

Installation-Related Enhancements and Changes

The Red Hat Linux 7.1 installation program includes a number of new
features.  For more information, please refer to the Official Red Hat Linux
Installation Guide.

    o Swap-related issues -- The 2.4 kernel is more aggressive than the 2.2
      kernel in its use of swap space.  However, as with previous versions
      of the kernel, the optimal sizing of swap space remains dependent on
      the following:

        - The amount of RAM installed
        - The amount of disk space available for swap
        - The applications being run
        - The mix of applications that are run concurrently

      No rule-of-thumb can possibly take all these data points into
      account.  However, we recommend the following swap sizes:

        - Single-user systems with less than 128MB physical RAM: 256MB

        - Single-user systems and low-end servers with more than 128MB
          physical RAM: two times physical RAM (2xRAM)

        - Dedicated servers with more than 512MB physical RAM: highly
          dependent on environment (must be determined on a case-by-case

      While it is certainly possible for systems with specific
      configurations and application loads to run with less (or even no)
      swap space, these guidelines attempt to ensure that you will not run
      out of swap.  The old saying certainly applies to swap space:

          "It's better to have it and not need it, than to need
           it and not have it."

    o Swap-related issues specific to upgrades -- If you are performing a
      fresh Red Hat Linux 7.1 installation, the sizing of swap partitions
      is a relatively-straightforward process.  However, if you have an
      older Red Hat Linux system that you wish to upgrade to Red Hat Linux
      7.1, please keep in mind that the size of the swap partition(s) you
      had previously created may no longer be sufficient.

      The Red Hat Linux 7.1 installation program now examines the available
      swap space.  If insufficient swap space exists, it will configure
      additional swap space in the form of a swap file.  The installation
      program will do this by asking you to select a partition on which to
      create a swap file.  You will also be asked for the desired size of
      the new swap file.

      (NOTE: In no instance will the Red Hat Linux 7.1 installation program
      create a swap partition or file larger than 2GB.  Should your swap
      requirements exceed this size, you will need to address this after
      the installation has completed.)

    o XFree86 4.0.3 -- The Red Hat Linux 7.1 installation program includes
      improved test screens and better detection of video memory, doing
      more than ever to help you get everything correct with a minimum of

    o Firewall Configuration -- For added security, you can now configure a
      firewall as part of your system installation.  You can choose from
      two levels of security, as well as choosing which common system
      services should be allowed or disallowed by default.

      Please note that both "medium" and "high" firewall settings will
      cause RPC-based services (such as NIS or NFS) to be blocked, and
      thus fail.

    o Hard Drive Installation - ISO images are now required for hard drive
      installations, making it no longer necessary to copy and install the
      entire tree. Instead, simply put the required ISO images in a
      directory.  During the hard drive installation, point the Red Hat
      Linux installation program at that directory.  In addition, since Red
      Hat publishes MD5 checksums for all ISO images, it is now possible to
      ensure that you are using officially-released software by running the
      md5sum program against your ISO images, and comparing the checksums
      against the ones published by Red Hat.

    o Language Selection -- Language selection has been significantly
      re-vamped.  It is now possible to install in one language, but
      specify that the system, after installation, will operate in another

    o Laptop Installation Class -- A New "Laptop" installation class is
      available, which enables PCMCIA support by default.  It should be
      detected automatically if your computer has a supported PCMCIA

    o LBA32 Support -- There is now support for the LBA32 option in LILO.
      This makes it possible to boot from partitions partially or
      completely above cylinder 1024 (which had been a historical
      limitation).  Note, however, that we have found that not all
      motherboards support this option, even when the BIOS claims support
      is available.  Therefore, this option is disabled by default.  Note
      also that this option is available ONLY when a partition has been
      created using fdisk, and that partition is then chosen as the /boot
      or / partition.  The fdisk restriction is necessary as it is not
      possible to create a bootable partition above cylinder 1024 using
      Disk Druid.

    o Disk Druid Improvements -- Disk Druid now detects partition table
      inconsistencies, such as partitions that do not end on cylinder
      boundaries.  This can be caused if the geometry of a hard disk drive
      is detected differently than when the drive was originally
      partitioned.  In these cases, we recommend that you use the fdisk
      program to more closely inspect these inconsistencies, or choose to
      skip the drive entirely.

    o Graphical Kickstart Configuration -- Red Hat Linux 7.1 now provides a
      graphical interface for creating kickstart configurations, allowing
      custom, unattended installations to be created with greater ease than
      ever before.

    o Improved Rescue Mode -- Rescue mode now attempts to mount the
      filesystems listed in /etc/fstab (assuming the root filesystem can be
      found).  The filesystems are mounted under /mnt/sysimage.  This
      eliminates a very confusing step for users using rescue-mode for the
      first time.

    o New Authentication Configuration Security Option -- Authentication
      configuration now includes the ability to use Transport Layer
      Security (TLS) when performing lookups.  TLS allows LDAP clients to
      use an encrypted connection when performing authentication.

    o Miscellaneous Installation Program Improvements -- Overall, there are
      many additional tests and checks performed to catch potential
      problems which previously caused tracebacks (installer crashes).
      This should reduce the number of poor out-of-box experiences for
      newer users.

System-Related Enhancements and Changes

There are many features new to Red Hat Linux 7.1 that are not part of the
installation process.  Some new features are server-oriented programs,
while others are new applications or desktop environment changes.  This
list will provide a bit more information about what to expect from Red Hat
Linux 7.1 once you are actually using the OS.

    o Upgraded Core System Components -- The following major system
      components have been upgraded in Red Hat Linux 7.1:

        - kernel 2.4.x (with additional fixes)
        - glibc 2.2.2
        - KDE 2.1.1
        - XFree86 4.0.3 with the Xft anti-aliased font render extension
        - GCC 2.96-RH, with many new fixes since the original 7.0 release

    o Improved USB Support -- The 2.4 kernel gives Red Hat Linux 7.1 more
      mature USB support than previous versions of Red Hat Linux.  It
      contains more drivers, and includes support for storage devices such
      as CD-ROMs.  It also supports "hot-pluggable" or removable devices --
      if a supported device is plugged in after booting, the necessary
      drivers will load automatically.

    o Removable media drives automatically added to /etc/fstab -- Red Hat
      Linux 7.1 now includes the ability for users to mount and unmount
      removable media drives.  This is done by the updfstab program (which
      is part of the kudzu boot-time hardware configurator).  It adds and
      removes the necessary entries in /etc/fstab.  Note that each entry
      managed by updfstab contains the new "kudzu" option -- this acts as a
      token indicating that the entry may subsequently be removed; if you
      wish to permanently add such an entry to your fstab, simply remove
      the "kudzu" option.

      Hotpluggable devices are handled through a combination of cardmgr,
      hotplug, updfstab, and pam_console_apply.  When the kernel notifies
      hotplug or cardmgr that a new storage device has been attached to the
      system, updfstab is run to add the new entries to the fstab.  Then,
      updfstab runs pam_console_apply, which uses the rules specified in
      /etc/security/console.perms to give the current console user access
      to the device.

      GNOME users who run magicdev will see device icons appear on their
      desktop automatically.  magicdev regularly checks the timestamp of
      /etc/fstab, and directs gmc to rescan devices when the fstab has
      changed.  If you do not run magicdev, the "Rescan Devices" option on
      the root gmc menu (which appears when you right-click on the desktop)
      performs an equivalent function.

      KDE users will see similar functionality.

    o New and Updated Drivers -- Many drivers are new to Red Hat Linux 7.1,
      or have been upgraded as a result of switching to a 2.4-based kernel.
      Changes include:

        - Updated Adaptec AIC7XXX SCSI driver
        - IEEE1394 (FireWire(tm)) subsystem
        - Adaptec starfire quad ethernet
        - Aironet 802.11 WiFI ethernet
        - National Semiconductor DP83810 ethernet
        - ATM subsystem and various ATM drivers
        - DECnet subsystem
        - Cyclom 2X, DEFEA, and DEFPA FDDI
        - IPv6 support
        - NFS version 3
        - iptables, an improved firewall layer
        - Maestro3 sound
        - Broadcom BCM5700 PCI-X 10/100/1000BASE-T controller
        - IDE UltraDMA/66 and UltraDMA/100 contoller support

    o 3D acceleration under XFree86 4.0.3 -- A wide variety of 3DFX cards
      have been added to the list of cards supporting accelerated 3D
      graphics. In addition, Intel i810, Matrox G200, G400, G450 (NOTE:
      dual-head operation on the G450 is unsupported), and ATI Rage 128
      based cards also support accelerated 3D graphics.  Please note that
      3D acceleration on ATI Radeon cards is not yet supported by XFree86

    o New Apache Configuration Tool -- apacheconf:

        - Helps manage virtual hosts in an intelligent fashion
        - Configured via the Alchemist Data Library

    o New BIND Configuration Tool -- bindconf:

        - Makes DNS configuration easier
        - Configured via the Alchemist Data Library

    o New Printing Configuration Tool -- printconf:

        - Filters are based on David Parson's magicfilter, the foomatic
          system, and the Linux Printing Database
        - Supports over 500 printers
        - Upgrades old systems configured with printtool
        - Configured via the Alchemist Data Library

    o Improvements to Red Hat Network, Software Manager service announced
       -- Red Hat Network, and its client program Update Agent, have been
       extended for this release of Red Hat Linux.  In addition, a new
       service -- Software Manager -- has been announced.  This technology
       includes the following enhancements over the previous release:

        - Update Agent now fully supports command-line operation.
        - Text-mode configuration utility is included.
        - Usage of the GUI mode can be disabled by specifying the "--nox"
          command line option.
        - More intelligent resolution of complex chains of package
        - "--whatprovides" and "--solvedeps" command line options allow
          querying of the Red Hat Network database to visually report
          package dependencies.
        - "--packagedir" command line option allows a list of directories
          to be specified.  These directories will be searched for packages
          when satisfying dependencies.
        - Kernel upgrades can now be processed by Update Agent.

    o Emacs/XEmacs site-start.d Directories -- Emacs/XEmacs each support a
      site-start.d directory.  Packages can now place emacs .el startup
      files in the appropriate directory, and they will be loaded when the
      editor starts.  This eliminates the need to edit the site-start.el
      file directly.  The directories are:


    o New ADSL/ISDN Configuration Tool -- internet-config is a replacement
      for adsl-config and isdn-config. It guides new users through setting
      up networking for these popular connection methods.

    o PostgreSQL Upgrade-Related Notes -- If you are upgrading from Red Hat
      Linux 6.2 or earlier, your existing databases must undergo a dump and
      restore cycle.  The best way to do this is to use pg_dumpall(1)
      BEFORE upgrading to Red Hat Linux 7.1.  After the upgrade, please see
      the README.rpm file in /usr/share/doc/postgresql*/.

      Also note that the upgrade keeps the old binaries around (along with
      a helper script) after the upgrade, but doing the dump before the
      upgrade and restoring afterwards (after removing the old database) is
      highly recommended.

    o OpenLDAP Upgrade-Related Notes -- The on-disk storage format used by
      slapd, the standalone OpenLDAP server binary, has changed.  Users
      upgrading LDAP servers from previous releases of Red Hat Linux will
      need to dump their directories to LDIF files using `ldbmcat -n' and
      re-import them into the new format using `slapadd'.

    o IMAP server changes -- The IMAP server now defaults to using its
      built-in SSL support instead of stunnel's tunneling support.
      Accordingly, the name of the certificate file used by imapd has
      changed from stunnel.pem to imapd.pem.  Users upgrading from previous
      releases of Red Hat Linux will need to rename, copy, or create a
      symbolic link to their existing certificate.

    o Sendmail -- By default, sendmail does not accept network connections
      from any host other than the local computer.  If you want to
      configure sendmail as a server for other clients, please edit
      /etc/mail/sendmail.mc and change DAEMON_OPTIONS to also listen on
      network devices, or comment out this option all together.  You will
      need to regenerate /etc/sendmail.cf by running:

            m4 /etc/mail/sendmail.mc > /etc/sendmail.cf

      Note that you must have the sendmail-cf package installed for this to

    o Other package highlights:

        - Ogg Vorbis audio encoder/decoder
        - Mozilla Web browser
        - LSB-compliant SGML and XML packages
        - KDE 2.1 and KOffice
        - BIND 9.x with DNSsec support and remote named control
        - SSL support in links, slrn, OpenLDAP, and pine
        - Pine 4.33
        - Quanta HTML editor (on Powertools)
        - Postfix and exim (on Powertools) include SSL/TLS support
        - WINE (on Powertools) can directly execute Windows .exe binaries
          from Linux

    o Deprecated Packages -- the following packages are deprecated, and
      could disappear in a future release:

        - AfterStep
        - Netscape 4.x
        - Qt 1.x
        - KDE v1 compatibility libraries / build environment
        - elm
        - linuxconf
        - ncpfs
        - mars_nwe

Known Issues / Trouble Spots:

    o PCMCIA support has changed greatly since Red Hat Linux 7; if you
      customized PCMCIA support under prior versions of Red Hat Linux, you
      should review your changes.

    o Some Java JVMs (both from Sun and IBM) don't work with the new
      floating stack feature of the i686 version of glibc.  The failures
      are due to programming assumptions in the JVMs that are now invalid.
      JVM vendors are working on making the necessary corrections.  Until
      corrected JVM packages are available, you may force glibc to use the
      deprecated stack model by setting the following environment variable:


Documentation-Related Enhancements and Changes

    o Additional documentation regarding the /etc/sysconfig/vncservers file
      -- Due to time constraints, the following information was not
      available prior to the Red Hat Linux Reference Guide's print date.

      The /etc/sysconfig/vncservers file configures how the Virtual Network
      Computing (VNC) server starts up. VNC is a remote display system
      which allows you to view a desktop environment not only on the
      machine where it is running but across different networks (from a LAN
      to the Internet) and using a wide variety of machine architectures.

      It may contain the following:

      VNCSERVERS=<value>, where <value> is set to something like "1:fred",
      to indicate that a VNC server should be started for user fred on
      display :1. User fred must have set a VNC passwd using vncpasswd
      before attempting to connect to the remote VNC server.

      Note that when you use a VNC server, your communication with it is
      unencrypted, and so it should not be used on an untrusted
      network. For specific instructions concerning the use of SSH to
      secure the VNC communication, please read the information found at
      http://www.uk.research.att.com/vnc/sshvnc.html.  To find out more
      about SSH, please refer to the Red Hat Linux Reference and
      Customization Guides.
