Introduction
The new Livingston Enterprises ComOS(tm) 3.3.3 software release is now
available for the PortMaster 2, 2E, 2ER, 2R and 25. This release is
provided at no charge to all Livingston customers. The following
document describes the features of the ComOS 3.3.3 software release and
how to upgrade your PortMaster. Upgrade instructions are included at
the end of this release note.
WARNING! YOU MUST USE PMINSTALL VERSION 3.3.1 OR LATER TO PERFORM THIS
UPGRADE! If you are upgrading using PMconsole for Windows, you must use
PMconsole for Windows version 1.1 or later. See "Upgrade Instructions"
on page2. If you have any port speeds set to 115200, upgrade to ComOS
release 3.3.3, and later downgrade to any earlier release you must set
the port speeds after downgrading.
New Feature in ComOS 3.3.3
ComOS 3.3.3 includes the following new feature:
For compatibility with the RADIUS RFC, Framed-Route attributes
delivered from the RADIUS server which contain network masks of the
type "/xx" no longer create an error condition. The PortMaster strips
the mask value from the destination address and ignores it.
Bug Fixes in ComOS 3.3.3
Basic rate ISDN lines using switch type 5ESS point-to-point (5ESS-PTP)
now establish LAPD sessions on their D channels immediately after
system startup. This allows some hunt group provisioning to work
properly.
ISDN ports configured for "host prompt" now accept synchronous PPP
connections.
When dialing from one PortMaster to another using the V.120 protocol,
users occasionally would not receive a login prompt until they pressed
the Enter key. This problem has been fixed.
ISDN calls made using French switch type VN4 now pass their called
telephone number using the "unnumbered" plan. This increases
compatibility with some switches.
Calls rejected due to service incompatibility now provide proper cause
codes to the switch.
A larger number of processes are now supported on the PM-2. This is
required at boot time on a fully loaded PM-2E with 15 ISDN BRI ports.
The PortMaster occasionally rebooted while auto-detecting asynchronous
PPP sessions. This problem has been fixed.
If a RADIUS server sent an Access-Challenge to users being
authenticated with PAP the PortMaster incorrectly treated it as an ACK.
This has been fixed. An Access-Challenge received for a PAP user is now
treated as a NAK.
Memory Requirements
If you are installing a MOD-10I-U or MOD-10I-ST expansion card into a
PM-2E-20 you should first install four megabytes of memory. This is the
only hardware configuration that requires additional memory in ComOS
3.3.2 or 3.3.3. For instructions on upgrading the memory see the
Communications Server Hardware Installation Guide.
Upgrade Instructions
If you are upgrading from ComOS 2.3 or 2.4 to 3.3.3, you must first
upgrade to ComOS 3.0.4, reboot, then upgrade to 3.3.3.
If you have any port speeds set to 115200, upgrade to ComOS release
3.3.3. and downgrade to any release before 3.3.2 you must set the port
speeds again after downgrading.
WARNING! YOU MUST USE PMINSTALL VERSION 3.3.1 OR LATER TO PERFORM THIS
UPGRADE! If you are upgrading using PMconsole for Windows, you must use
PMconsole for Windows version 1.1 or later.
The 3.3.3 upgrade image is available for the PortMaster 2, 2E, 2ER, and
2R at ftp://ftp.livingston.com/pub/le/upgrades/pm2_3.3.3 and for the
PortMaster 25 at ftp://ftp.livingston.com/pub/le/upgrades/pm25_3.3.3.
ComOS 3.3.3 uses the same RADIUS dictionary file as ComOS 3.3.2. The
dictionary file is available at
ftp://ftp.livingston.com/pub/le/radius/dictionary.
The installation software can be FTPed from
ftp://ftp.livingston.com/pub/le/software/system/tarfile.
umask 22
mkdir /usr/portmaster
cd /usr/portmaster
tar xvf tarfile
./pminstall
To upgrade a PM-2, PM-2E, PM-2ER, or PM-2R to ComOS 3.3.3, run
pminstall and choose the Upgrade PortMaster option, choose pm2_3.3.3
from the menu of upgrade choices, enter your PortMaster's hostname or
IP address, and enter your PortMaster's administrative password.
pminstall upgrades your PortMaster to ComOS 3.3.3.
To upgrade a PM-25 follow the above instructions except choose
pm25_3.3.3 from the menu of upgrade choices instead of pm2_3.3.3.
The upgrade does not affect your stored configuration in the
PortMaster. If you would like to backup your PortMaster configuration
before upgrading, run pmreadconf:
cd /usr/portmaster
./pmreadconf pmname pmpassword data/pmname.conf
chmod 600 data/pmname.conf
