KEYWORDS= Davrom Consulting Newsletter - Issue # 40 - Dated: 3 Mar 2008


From the desk of David Clark

To those who wish to join me in some amusement go to Google and search
for "microsoft lawsuit red hat suse" - and you will find pages detailing
the latest antics from MS - can you believe it? Yet another tactic to
try an gain world dominance and extract the dollars from those who
would suffer the most, the end user, over unfounded claims.

I have been observing the resistance to the introduction of Vista in the
industry so I have touched on some of the problems we have seen to date.

I would like to thank the reader for their time in reading this
newsletter.

Outlook IMAP issues with Linux servers

As I have discussed in previous articles, IMAP allows you to store your
e-mail on the mail server so that you can access your e-mail (and
folders) from anywhere (Webmail, mobile phone, laptop, PC). Unlike POP,
all of your e-mail is stored in plain text format under your UNIX/Linux
user $HOME directory. POP is no longer favoured as your e-mails are
stored within your e-mail client and are in danger of being destroyed in
the event of a hard disk crash - coupled with the fact you can only get
at your e-mail from one single point.

For those using MS Outlook there are some added issues when running it with
an IMAP based server - moreover a non-MS Exchange server. Outlook was designed
to run with MS Exchange and that is that.

One main issue customers have found is when deleting e-mail messages the
traditional "Deleted Items" folder is not updated or used with IMAP. Upon
further investigation this is not an issue with the IMAP server but some
underlying coding/technology in Outlook. Items deleted stay deleted so if
you are using Outlook with Linux and IMAP, perhaps setting up some rules or
manually moving the items to a folder for later manual deletion is advised.
Given you are running Linux you could then setup a script to auto-cull
the deleted items folders on a regular basis by using the systems cron
facility.

As Outlook is moving more and more to being MS Exchange compatible only,
the better solution is to use another e-mail client that is friendly with
all e-mail servers such as Thunderbird, Eudora or Incredimail.

I started using Netscape Messenger in 2001 and have since been using the
later Thunderbird product in both the Linux and MS environment - it is
truly one of the best available. (And it is free).


Vista issues

The two main issues we have encountered with customers installing Vista
into Linux and UNIX environments is the new personal firewall security (User
Account Control - Cancel or Allow), and the non-communication with the
old LAN Manager (LAN Manager 2) based servers and PCs.

The first step is to disable or at least extensively configure the
personal firewall to allow communication from other non-Vista network nodes
such as Samba servers and Windows XP/2003/98 PCs. Even after doing this
you will sometimes find that even though Vista is on the network it becomes
inaccessible/invisable after a period of time from other PCs and servers.
That is until you tell Vista to go and access something on the other PCs
or servers - then it reappears. Still working on the one-ways comms issue
here.

The main issue for most customers is the ability to access the share
folders on other machines and to allow others to access the Vista share
folders. This can only be done by editing the Vista security policies
(secpol.msc) and changing it from the default NTLVM2 to use "LM and
NTLM - use NTLVM2 if needed". Only in this mode can you access the share
folders on Vista from the other servers and PCs. If you are running a
very old version of Samba (such as those still on OpenServer) you will
need to upgrade Samba to a later version otherwise access to Vista will
never happen.

Market resistance is high and most companies are even reverting their new
hardware back to XP or earlier just for ease of use and integration into
their existing LAN/WAN.

I would welcome any feedback you have found with Vista in your
environment.


From the Trenches
Some comic or not so comic relief from the support days gone by.
An I.T. Parable:

A man is flying in a hot air balloon and realises he is lost. He
reduces height and spots a man down below. He lowers the balloon
further and shouts: "Excuse me, can you tell me where I am?"

The man below says: "Yes you're in a hot air balloon, hovering 30 feet
above this field."

"You must work in Information Technology" says the balloonist.

"I do" replies the man. "How did you know."

"Well" says the balloonist, "Everything you have told me is technically
correct, but it's no use to anyone."

The man below says "You must work in business."

"I do" replies the balloonist, "but how did you know?"

"Well", says the man, "you don't know where you are, or where you're
going, but you expect me to be able to help. You're in the same
position you were before we met, but now it's my fault."


Tech Tip

Sending attachments with mutt:

Have you ever needed to send a file from the Linux/UNIX command line only
to find that it arrives in your mailbox as just jibberish or something
you simply can't get at? The command below will send a file as an
e-mail attachment using the mutt command:

mutt -s"File attached" -a /tmp/budget.doc david@davrom.com
This will e-mail the file /tmp/budget.doc to david@davrom.com with the
subject "File attached". Don't forget to include the " end to prevent mutt trying to talk to you interactively.
