More partners involved means security

"we can't use the GUI unless we are connected to the network via an Ethernet cable; our
wireless blocks the port we need." (Aleph500-Discuss-L Thursday, July 25, 2013)
BYOD (bring your own device) GYDD (get your devices donated)
Recently we received a donation of Apple devices. Ex Libris has advised that the ALEPH client
could be used on these with the help of a Windows emulator such as Wine. Could mac users
share their experiences and advice on running ALEPH on mac e.g. the best/most popular
windows emulation to use, setup & configuration and ‘gotchas’. (Aleph500-Discuss-L Monday, June

Networked GUI; why
•
•
Easy to deploy
Cost efficient to maintain and update
o
•
•
o
Facilitates using test and production server
using only one client installation
Enables roaming use of client by profile
o
•
Keep central settings central and offer personal or
functional settings local
No need for Version check on client
Although Ex Libris advises profiles should be stored
on client device this is not necessary
Facilitates server based computing
o
BYOD and GYDD
Key elements networked GUI
1. File Server
2. Profile.dat
3. Client files
4. Profile files
● File serving: just a shared folder on a server!
● Is installation really necessary?
○ No, even installing the main network on
any windows PC and then copying the file
tree to any file server suffices
● The file server is the CENTRAL installation,
serving the executables and default settings for
ALL clients
○ only clients that need different settings
should have supplemental settings in their
profiles
● Profile.dat is the essential file on the file server,
determining where the profiles reside
● The GUI is a Windows application !!!!
○ Installation on a windows device
(PC) is mandatory
○ The GUI runs on the client
device, so the system files (*.dll,
*.ocx, fonts etc.) should reside
there (folders depend on 32/64
bits)
○ No executables on the client
device, only shortcuts to the file
server
○ Peripherals attached to the client
device
■ Keyboard devices like
●
●
■
Barcode readers
RFID readers
Printers (preferably avoid, use
networked printers!)
4. Profiles
● Used for personal and functional profiles
○
Settings other than or additional to defaults
■ Printer settings (slips, receipts etc.)
■ Email settings (sender address for replies)
■ StationID: %profile\alephcom\tab\stationid.dat
●
●
■
■
Statistics in transaction tables, also for ARC
Transport between sublibraries,determining when home
configured on Alephserver/AXX_1/XXX50/tab/tab_attr_sublibrary
Save defaults buttons in Items and ACQ
All other client settings like colors that normally are
not changed by staff but can be
● Stored on:
○
○
Personal: network (home directory or windows profile)
Functional: networked share for all staff users

Networked GUI; how
Choose the file server to use
Install the main network based GUI on server
Prepare the file Profile.dat on server
o
Decide where the profiles should be stored
o
Decide how functional profiles should be used
o
Prepare the functional profiles settings
Prepare the network based client setup
o
net500.exe
o
net500.ini having path to file server installation
Run the network based client setup on client
o
can be silent, no need for user actions
Done

Adding new elements & techniques
SAMBA for file server
● SMB (Samba) offers file server to Windows
● Aleph server renowned for robustness
● Running file server on Aleph server, less
TCO

If Aleph server is single point of failure, why not
Aleph network file server?
Install SMB-deamon on Aleph server
Configure users and access rights
Copy Aleph main network file tree to Samba share
Point Aleph client shortcuts to Samba share
Trash your Windows file servers
Landscape
Aleph server + File Server + Profiles functional
Client PC
Profiles personal
Adding new elements & techniques
Terminal server traditional
Why
● Making Aleph available from home
● Preparing for thin client workstations
How
● Run the network based client setup on a Windows
Terminal Server (2003 that time)
○ 32-bits and 64-bits
● Configure users and access rights
Can replace PC’s or be an add on for PC’s

Making Aleph available via browser
Preparing for:
○ BYOD (bring your own device)
○ GYDD (get your devices donated)
○ Outsourcing Aleph client hosting to;
■ Central ICT in University
■ Commercial partner
■ Ex Libris cloud
○ Outsourcing Aleph server hosting to;
■ Central ICT in University or consortium
■ Ex Libris cloud
Facilitates Aleph GUI deployment for customers without any ICTdepartment
Landscape in cloud
● Aleph Server
○ File Server possible
● Terminal Server
○ Network based GUI
○ File Server possible
● Profiles functional
● Profiles personal
And now..............

Networked GUI has many scenarios
All scenarios lower TCO
Aleph server can act as file server (Samba)
Terminal server can host network based client
Ex Libris should certify GUI for Windows server
2008R2 and 2012 (64-bits)
Terminal server web offers GUI to BYOD/GYDD
Terminal server facilitates GUI in Cloud
Cloud can host Aleph terminal server
Should Ex Libris offer Aleph server combined
with Aleph terminal server in their cloud?
