4. Client Software requirements
This section describes the software requirements for the workstation that is accessing the e-
collabcenter.com web site. The workstation is sometimes referred to as a client machine. Ensuring that
your workstation meets these software requirements will enable it to work optimally the E-
CollabCenter environment.
4.1 IWS Conflict
Previously Sametime and IWS could both use JRE 1.4.2_14. However in order for Sametime to support
FIPS 140-2 encryption, E-CollabCenter (which is based on Sametime technology) requires Java JRE 1.5
Update 12 or greater.
IWS 3.0 does not support JRE 1.5. IWS 3.0 is the version used by most of DoD. IWS Version 3.0.6 will
be released soon and it is JRE independent so it would not conflict with Sametime at all (theoretically)

.
This means that a workstation running IWS would have to install JRE 1.5 (update 12 is preferred) and
most likely have to uninstall JRE 1.4.2 in order to use E-CollabCenter.
4.2 Linux clients
Library required for application sharing on Linux systems
In order to load Application Sharing native code on Linux platforms, the following library is required on the
client machine: libz.so.1, which resides in /usr/lib.
The supported Linux operating systems are: RedHat Enterprise Linux 4.0, Ubuntu 8.04, CentOS 5.1 and
Novell Linux Desktop 10.0 using Firefox 1.5. Limited testing has been done by the IBM E-CollabCenter
project team with these Linux desktops.
4.3 Windows clients
The recommended operating system for E-CollabCenter is Windows XP with Service Pack (SP) 2. Prior
versions of Windows such Windows XP SP 1 and Windows 2000 may work but have not been tested by
the E-CollabCenter team. Limited testing has been done using Windows 2003 Server SP1 and SP2 as
an E-CollabCenter client; they both appear to work fine.
For the Sametime Broadcast client, Sametime Connect (a.k.a. thick client) client, Sametime Meeting
Room client the Microsoft Virtual Machine (VM) is not supported and must be disabled. The
supported JRE for all Sametime java applet clients in the Sametime 7.5.1 release is Sun Microsystems
Java JRE release 1.5.0 (update 12 is preferred).
4.4 FDCC & SDC v2.0.4 Windows clients
The Federal Desktop Core Configuration (FDCC) is an OMB-mandated security configuration. The
FDCC currently exists for Microsoft Windows Vista and XP operating system software. While not
addressed specifically as the “Federal Desktop Core Configuration,” the FDCC was originally called for in
a March 22, 2007 memorandum from OMB to all Federal agencies and department heads and a
corresponding memorandum from OMB to all Federal agency and depart Chief Information Officers
(CIO).
The Windows Vista FDCC is based on DoD customization of the Microsoft Security Guides for both
Windows Vista and Internet Explorer 7.0. Microsoft’s Vista Security Guide was produced through a
collaborative effort with DISA, NSA, and NIST for the Windows Vista platform. The Window’s XP FDCC
