How do I integrate my Unix work station in an Exchange Enviornment?

I am in the military and have been assigned to work on a Unix worksation  thats sits on Windows 2003 Server network. The wonderful software engineers that developed my system did not take several things into consideration. I'm not knocking them believe me because my system does exactly what it is supposed to do and very well at that. The problem I am having is collaborationg with the Windows enviornment. I cannot get sendmail to work and at my wits end. I have exhausted my limited Unix knowledge and have spend way too many hours reading google search results with no solution to date. PLEASE HELP! The higher ups are all looking at me to fix this issue and fast.

Thanks
SSG Jamie A. Nelson

man sendmail
man nslookup
man bind

should be telling your all you need.

> ..  cannot get sendmail to work ..
sorry, this is a totally useless statement.
Could you please give information *what* is not working?
Which messages do you get?

Sorry, I'll try to be a little more specific. I know that sendmail is working. I monitored the logs and the emails are going out. I checked my hosts tables and everything looks good. It keeps returning as connection refused from the exchange server. I've tried everything at this point that I can think. And because it is a miltary network they will not turn on IMAP4 access for use of Netscape.
It keeps returning the same error : Connection Refused by 148.xx.xx.xx xxx.army.xxxx.mil (sorry about the address exclusions but they said I had to lol)

I also had to exlcude the AutoRebuildAliases function because when it was included sendmail would not start. But when I do exclude it sendmail starts and returns the message WARNING: Dangerous write permissions.

I've been through everyline in sendmail.cf and I believe that I have made the appropriate entries. As I said I am an Air Traffic Controller and while I can run an airfield all day, I am quite possibly the least qualified UNIX terminal operator on the market LOL. But we do what is ordered so if I have trouble conveying my problems please have patience with me.

Thanks
Jamie

Are you talking about a server (MTA) or a client (MUA)? In other words: do you just want to get your mails stored on another server?

> It keeps returning the same error : Connection Refused
this have to be fixed on the remote server. You can't do it yourself (except by cracking the remote onw :-)

being patient, but sounds that we nee to clarify the basics first

Jamie, this is just a comment on the side because it looks like ahoffmann is taking care of your problem.
So just to ask the obvious: is there an smtp server on your machine (148.xxx.xxx.xxx)?
It seems to me that Exchange is not SMTP.

ahoffman/Bill,

The basic flow of information would looke like this:

My Unix Operator Terminal   <--------->  Remote Site Unix Terminal  <----------> Remote Site Unix Radar Service Provider
   (Master Terminal)                |   \                           |                            /
         \                                   |     \                         |                          /
           \                                 |    Remote Unix Systems Integration Server
             \                               |                               |
               \                             |                               |
                 \                 Windows Server (2003) SQL Database Home
                   \                         |
                     \_______>Windows Exchange Server (2003)
                                             |
             Windows XP Based Network User Enviornment    

I have every piece of collaborative technology working between the cross system platorm excluding sendmail. Our resident Windows "IT Experts" said it wasn't a problem on "their" end. But talking to them is the equivalent of a create-your-own-adventure novel (if this happens go to page 63 ... if not then proceed to page 110 .. etc etc). As far as the IMAP goes I've already asked ... no correction ... I've pleaded for them to turn it on. But alas, they said no. They said that it would open the server to possible "security weakness". I had to laugh at this because we are on closed network that never touches a land line. I have no problems sending mail Unix to Unix or collaborating across the board with other Unix hosts. It's just that damn freaking exchange server. I know your probably ready to shoot me by now .. lol ... but I have one last question. I have Windows running on my unix platform via a dual motherboard and an emulator very similar to VMWARE. Is there a way to create a network drive on my machine to transfer information directly from SunOS to the WindowsXP? That would solve ALL of my problems in one nice neat clean package and get all these damn Officers off my back. Just once I'd like to see one of these smug West Point graduates sit behind my console and try to get equipment built by the lowest bidder to work! But then maybe the Tech Gods only bestow thier ultimate knowledge on college grads ..... I guess I'll never know ... roflmao.

LOL, that's what MSCEs always say (a bit narrow minded, somehow), be patient with them: thy had to pay for their certs :-))

>  Is there a way to create a network drive on my machine to transfer information directly from SunOS to the WindowsXP?
Install Samba on Unix, and ready you go from both ends.

Jamie,
Probably the Officers suffer from fear of failure: if you fail, they (presumably) get some of the "blame".
So they push you to avoid their own failure.
Is it the case that they are expecting you to do this because there is no other person available with the knowledge needed?
Or, are they testing you to see how you handle being put in such a situation?

There are both technical and non-technical parts to this problem.
On the non-technical side, this is something like trying to get your helicopter repaired at a fixed-wing airfield (no, I'm not a pilot, just trying to make an analogy that may be understandable to the military officers.)  In such a situation, it helps a great deal to have the officers make it very clear to the airfield people (who are analogous to the Windows experts) that they share the responsibility for making this work.  People from different backgrounds need to work together to solve such a problem.

Okay first the question I forgot to answer:

>Are you talking about a server (MTA) or a client (MUA)? In other words: do you just want to get your mails stored on another server?
No, I do not want to get my mail stored on another server. Any email I recieve is sent via Unix to Unix or through my Outlook account in VMware. I am attempting to email current Outlook Accounts on the exchange server for the units that do not have access to the Unix enviornment.  As well as send my airspace picture data (provided in a text to graphic conversion format called USMTF) to the SQL database that provides the high command with a Common Operational Overlay. All of this is done through Outlook accounts across our division. The Maneuver Control System that uses the MDR of the SQL server is designed to import information only one way ... via Outlook. And untill I figure out how to 1) 'install Samba' and 2) 'use Samba' I am stuck trying to figure out the email issue. I hope that answers your question pretty thoroughly and doesn't send us back to square one again. LOL.

Bill,
In answer to your question. Yes I am the sole lonely guy at this outpost. And unfortunately (I know this part is gonna be scary), but I am the most computer proficient individual on the staff. I've always been the "gotoguy" when something goes wrong and they know that I will make it happen. And as to the failure thing .... if this fails ... then we don't; the system does. I am more worried about that than I am about getting yelled at for not getting it to work. This system is light years ahead of anything out there right now and it will not only improve situational awareness but will significantly reduce the time it takes to handle emergency aviation matters and response times of aviation forces in combat. And when your talking situation awareness and time in combat then that translates to lives that can be saved or lost. That is the true motivation behind getting all the bugs worked out of this system. All my other comments were just posted in jest and held no malevolence to them at all.

You both have truly impressed me with your timeliness in response and willingness to help.

Thanks
Jamie

You "email account"? what does this mean?
You try to send emails to accounts on the exchange server?
Then you simply need to contact the exchange server and deliver the mail (which is your initial question, and the anser is http:#13748475 means that admins on exchange have to accept connections from your server, or tell you where to send the mails to)

Jamie,
I did not find anything "malicious" in your words, just normal frustration.
That can happen on any IT project, military or civilian.
As ahoffmann says, the administrators on the excahnge server MUST be part of the solution.

Jaime,

despite all your comments your question is still to vage, I am going to take a stab at the problem and going to type a lot, hope to be clear and the guys here will keep me straight with sendmail, with Exchange I will not even attempt to comment, my knowledge of sendmail is too limited and anything related to Microsoft I just plain do not know.

In the SMTP world there are user agents and transport ones, the user agents are the ones that we usually interact with, outlook, eudora (still around?), netscape, etc.etc... transport agents are the ones who deliver email between sites and in behalf of the users, in order for me to send an email, my client application has to deliver it to a transport agent and it will relay it to the world.

thanks to spamers now transport agent admins are becoming paranoic and for the ones that are not yet, transport agents default config is not to relay or receive email from un-resolvable domains or to receive email from a local user from a remote location, unless specifically permited to, also your client has to satisfy different rules for the transport agent to agree to relay your message on your behalf.

if you are trying to deliver an email from your unix machine/terminal/workstation/server you are not using an outlook account to deliver it, and you'd better do not try to impersonate one, otherwise you will never be able to send the message across. You need to deliver your email from your UNIX box to the Exchange server via SMTP, but the Exchange Server has to trust your Unix workstation/server/terminal and has to be configured to "listen" for SMTP connections, on how to configure and make it play along I have no clue.

now, afaik, most of unix mta's only speak SMTP/IMAP/POP to talk to servers, Exchange might be configured to receive smtp messages, unless it receives emails from other sites NOT using exchange, you might be out of luck here, try poking for port 25 on the exchange server using telnet from ur unix box  ie  "telnet <server's_ip> 25 "  (without the quotes) if you still get a connection refused, you will have to use an exchange client, yes an Exchange client on Unix. I do not endorse any product or service but I believe your answer would be "Evolution" from Novell (http://www.novell.com/documentation/ximian/evolution.pdf), it is the only product I know has a connector from Linux to Exchange, at this point Novell might have connectors for different architectures. there is also a company that provides the API on Linux to run Microsoft office applications it is called CrossOver Office (http://www.codeweavers.com/products/cxoffice/?cw=cff01678c8de6dbe8e0aa6a7505f5383), but again, this is limited to Linux, you might try WINE (http://www.winehq.com/) a free API for LINUX again..but this uses GPL so if you are not using Linux you might be able to make it run on your workstation.

good luck,
esv.
