Hello again.
�
Here is more food for thought.
�
Can you use Linux on the desktop? The answer is yes you can.
�
I am assuming that you are using MS office,�but you can certainly use a linux office
suite to replace the�MS office suite.
�
Citrix offers a linux ICA client so you can connect to a citrix server using linux
workstations.
�
This setup; however, will not release you form your licensing agreement with MS and
the MS Terminal Server. You will still need to have the appropriate client licenses
and access licenses.
�
What you gain is the ability to to use smaller machines for the same purpose and less
technical support issues.
�
If you really want to move to a linux server. the same company that offers win4lin
offers a Terminal Server solution. Tarentella is another one that I know of. This will
only replace the Citrix part of your network. You will still neeed MS terminal Server
as long as you access MS programs.
�
(There are more thin client solutions, but they just don't come to mind right now)
�
I don't suggest running MS programs on top of linux. I don't see any real advantage to
that set up.
�
I don't suggest moving the databases to another server. Once again there is no real
advantage to it.
�
Some questions you might want to ask about the database programs. Do they use stored
procedures within SQL server? Does the user interface connect through a DSN?
�
Is the user interface a VB/C++ interface or a web interface.
�
Contact the companies and see if they support MySQL. My guess is they don't, but it
never hurts to ask.
�
If you need more hard drive space - add more hard drives.
�
If wish to add new CPU or Ram , you may want to run the performance monitor to get an
idea of what the current load is on your server.
�
The Lotus Domino Server can run on Linux and the Windows Notes client can run on a
Linux desktop using WINE. (Instructions for seting up Notes with wine is provided on
the Lotus Notes web site ,but it is� use at your own risk.)
�
I also do not know if the widows Domino license you have is transferable to Linux. You
would have to contact IBM for that information.
�
A possible senario would be like this:
�
2 servers - one Linux and one Windows.
�
The Windows Server runs Terminal Server and MS SQL server and possibly Citrix.
�
The�Linux server runs Lotus Domino Server and also functions as a file and print
server.(Removing Domino Server from the same server that runs MS SQL may�free up
the�necessary resources on the windows server.) If you choose to use a Citrix
alternate you can run it on the same linux box.
�
If you want to stay with one server. I suggest you stick with what you have.
�
You can run Linux on the desktops if you wish. Keep in mind the issues that I have
already covered.
�
The firewall can be any�of a number of solutions now being offered. Take your pick.
�
I hope this answers some of your questions.
�
Feel free to email me at any time if you want to discuss this further.
�
Wil

Subject: a serious question
I asked about a week ago a question from my doctor, DR.Greg Silver at the
local medical centre..
I had two replies to which he has answered in a more indepth manner.
I quote his repliy and additional questions below and would appreciate it if
anyone with knowlegde than I could answer him direct and cc to me please.

Thank you Keith and Linux affecionados: I am relatively new to Linux,
having a copy of Esmith server and lots of user reports of its utility.
The network setup is as follows:
Lan:� NT4 Terminal Server Edition with 5user Citrix metaframe license.
12user CAL���� P2 450 512MB RAM.
Netfinity5000 server.��� RAID for twin HDs
��������� NT4 workstations *8, soon to be 11,� P2 450� 64MB RAM�� 10/100
ethernet.� 16port hub, not switched. Internet
���� router with firewall, not meant to be user or application specific,
just to keep others out.
Wan: *3 citrix clients over individual copper phone lines.
The software running is:
���� 1. A medical practice management program. Windows based. MS SQL
database.
���� 2. A medical clinical notes patient management program. Windows based,
presently Foxpro database,����������� moving in Nov01 to MS SQL database
also
���� 3. Lotus domino server. Lotus notes clients.
The system is just over 2yrs old. The speed on lan is fine. Over wan is
acceptable. Bandwidth is probably the limiting factor here.��� With
increase in lan and movt of both programs to client/server architecture the
server may not cope cpu wise. Also the HDD space needs an increase,
presently twin 9.1 GB, RAID mirroring. Hot swappable. Do we increase the
existing HDD space within the same server box, with only a cpu upgrade to
P2 600 possible? Or can we run a linux file server? Can it allow the MS SQL
database to reside on the linux server, to be accessed by the two main
programs elsewhere? Will this help?� Will it slow the system to separate
the programs from the database hardware, particularly for the citrix
clients, who always suffer if there is sytem speed degradation. Is citrix
necessary with Linux?� Can linux run the windows programs in� win-4-linux
or whatever it is called?
Thank you for any advice re linux in respect of the above, or the needed
enhancements.
Greg Silver
