Subject: Enterprise Linux 4.0.2 for routers available
Version 4.0.2 of ImageStream's Enterprise Linux is now available as a general
availability release for all ImageStream router customers.
This software release is provided at no charge to all ImageStream customers, and
is recommended for all customers who wish to upgrade to the latest available
VERSION 4.0 RELEASES ARE BASED ON THE LINUX 2.4 SERIES KERNELS. LINUX 2.4 USES

This release note documents commands and features added between Version 4.0.1

New Features in Version 4.0.2

ImageStream's SAND Version 3.5.8 release is included in the Version 4.0.2
release. See the release notes for Version 3.5.8 for more information about the
SAND Version 3.5.8 software release. SAND Version 3.5.8 is a maintenance
release and also adds the ability to disable LMI on frame relay links.
Diagnostic Utilities Added
Version 4.0.2 adds new X/Y/ZModem send and receive utilities. sz and rz allow
administrators to send or receive files across a serial modem or console
connection to an ImageStream router.
OpenSSL Upgraded To OpenSSL 0.9.6e
The version of OpenSSL included in Version 4.0.2 addresses a recent security
advisory. Version 0.9.6e included with this release patches the July 30, 2002
advisory regarding SSL2 and SSL3 vulnerabilities. IMAGESTREAM ROUTERS DO NOT
USE THE SSL LIBRARY AFFECTED BY THIS ADVISORY AND ARE NOT AFFECTED BY THIS
ADVISORY. Version 4.0.2 updates the OpenSSL cryptography library used by
ImageStream routers. This library is NOT vulnerable and is being upgraded as a
precaution against any future vulnerabilities.
Bugs fixed in Version 4.0.2
The following bugs have been fixed in Version 4.0.2:
Ethernet Sort Ordering Problem Fixed
Version 4.0.2 fixes a boot-time problem with certain revisions of Gateway
Routers with multiple Ethernet devices. Earlier Version 4.0 releases could
cause the order of Ethernet devices on these routers to shift. Version 3.2.x
releases were not affected by this problem.
Limitations and Upgrade Instructions
*** NOTE! If the upgrade fails, do NOT reboot! Contact ImageStream's Technical
Support without rebooting. ***
Upgrading to Version 4.0 or later requires the following:
1. 64 MB of RAM or higher.
2. 32 MB of flash.
3. 300 MHz processor or better.
4. Enterprise Linux Version 2.3.2 or higher.
The upgrade utility will not install Version 4.0 if memory and flash
requirements are not met. Users can contact ImageStream to purchase a RAM,
processor or flash upgrade.
Users running an Enterprise Linux version less than 2.3.2 must upgrade before
Version 4.0 will be available from the Update menu. Upgrading any version prior

required to install Version 4.0.
The upgrade does not otherwise affect the stored configuration in the
ImageStream router. To back up the router's configuration prior to upgrading,
choose option 4 (Backup/Restore) from the router's main menu. Choose the Backup
methods option (Option 1) and select a method from the choices listed. From the
router's command line, use the "backup" command. The backup utility takes four
arguments: flash (to back up configurations to the router's nonvolatile flash
memory), floppy (to back up to a floppy disk), scp (to back up via secure copy),
or file (to back up to a separate file on the router's nonvolatile flash
