- This is the summary of the posting I did for SCO Unix. Thanks to all
- who contributed to the posting. It was a REAL education!
- Enjoy.

- Topic for Summary: SCO vs Any Other Unix
- ___________________________________________________________________________
- ===========================================================================
-
- I am contemplating buying SCO ODT or SCO Unix. I have heard from one
- person that SCO is not as good as some of the other flavors. I may be
- opening myself up for a large response, but could anyone comment on this?
- I realize that this may have been covered extensively or may even be an
- FAQ. I would appreciate any comments to this subject. If there is any
- large response, I will summarize.

-
- We are indeed very happy with the technical support, performance, and
- reliability of this product. I would be happy to discuss this with you
- at length if you desire. We are entirely independent of SCO interests.

-
- This depends a great deal on what you want to do with your Unix. If
- you want a "business Unix" system that runs and runs and runs, with
- little maintenance or downtime, get SCO. There are also lots of
- shrinkwrapped applications available for it, and despite what you
- might have heard about SVR4 running SCO applications, it's still going
- to be a lot easier to run them on a real SCO system. The latest
- releases (ODT 2.0 and SCO Unix 3.2v4.0) have eliminated most of the
- major complaints that people had about SCO -- inability to deal with
- long filenames and symlinks, the security that couldn't be turned off,
- and so forth. Support from your vendor will usually be really good
- with SCO, and SCO has its own support system that works pretty well.
- SCO's documentation is second to none.
-
- On the other hand, if you're looking for a system to use at home or to
- play around with, you'll be happier with SVR4. PD software tends to
- compile with less trouble on SVR4 than on SCO Unix (but then again,
- SCO is getting better in this regard), and SVR4 has more neato-keen
- features than SCO. SVR4 isn't as stable as SCO, though, and there are
- fewer shrinkwrapped applications available for it. SVR4 will tend to
- be less expensive than SCO, but the documentation isn't as good and
- support may be more of a problem.
-
- If you decide to go with SVR4, I'd highly recommend Dell's offering.
- Although there are a few odd things about it, Dell seems to be a lot
- more responsive about fixing bugs in the USL code and supporting its
- product. Esix might be a bit cheaper, but you don't get the same
- goodies you get with Dell, and Everex doesn't seem to be as interested
- in after-the-sale support.

- Yes indeed, this has been the topic of many "religious like" flame wars in
- this group. Get out your asbestos suit :^)
-

-
- Seriously though, there is one big difference; SCO is based on System V
- release 3.x, while many other vendors offer ports of System V release 4.x.
- SCO has recently been using the phrase "version 4", which is relevant only
- to thier own revision control, SCO is definitely not SVR4! SVR3 is "pure"
- System V UNIX, while SVR4 has stuff from BSD UNIX folded in. If you like
- pure System V, then you may like SCO, but most people I know (myself
- included), like BSD, and hate System V. SVR4 conatins enough BSD-isms to
- keep most BSD fans happy, although it's still a matter of personal taste!
-
- SCO has several other negatives; (1) It pretty expensive when compared
- to the competition. (2) It's still pretty buggy. Just watch this group for
- awhile, and see how many postings like "Trouble with blah under SCO", etc.
- you see. Not very comforting, although one could argue this is because SCO
- has sold more copies than anyone else. They *have* been around awhile, *and*
- they are popular, but then this is also true of MS-DOS :^)
-
- As I mentioned, I like BSD, so SCO was out of the question. I bought
- Dell's SVR4, and have been very happy with it. Another thing to consider
- is the various free UNIX flavors that have popped up, like BSD386, and
- linux. Can't beat the price!
-

-
- I have only used SCO and Interactive UNIX, and I tend to use them
- differently than a "normal" user might use them (I use them to develop
- networking products). In my experience the SCO implementation of TCP/IP
- is _much_ more robust than that from Interactive. I have uncovered at
- least one admitted bug in the ISC implementation, and I have seen much
- other bizarre behavior. Although I have no deep abiding love for SCO,
- their TCP/IP is much better.
-
- I don't know if TCP/IP figures in your plans, but this would make a big
- difference to me in making a choice.
-

-
- Last I heard, SCO was not following the SVR4 route and had no intention
- of doing so. This means again, SCO's products will be 'non-standard'.
-
- Do consider, however, that SCO has a large market presence and the
- resources to provide support and maintenance for some time to come. Be
- prepared to pay for more than installation support. SCO appeals to
- business owners who feel a need for the security of things like service
- agreements.
-
- I am looking toward SVR4.2/Destiny as the cohesive UNIX that everyone will
- use, not SCO. I expect several of the smaller (ESIX, Dell, etc.) to pick
- up SVR4.2 as a product and provide better tech support than SCO can provide.
-
- For now, I think you would be better off with Everex ESIX or Dell UNIX.
- Both have inexpensive or free tech support, are current versions and have
- a significant base of ported free software.
-
- ___________________________________________________________________________
- ---------------------------------------------------------------------------
-
- YOu will get a lot of personal opinion but most systems out there are still
- SCO and will continue to be so for quite some time to come. What you need to
- measure is support for the long run and that is where SCO shines in not simply
- deserting the past and jumping into the future while leaving many customers
- floating in obsolescence.
-

-
- I have installed and used SCO Xenix, SCO UNIX, ESIX, Interactive 386/IX,
- Consensys V.4 and probably a few others. On the plus side, the SCO stuff
- works. But bug fixes are slow to appear, the software is expensive and
- tech support for knowledgable users is a pain as they assume everyone is a
- newcomer. The main reason I wouldn't buy SCO products for a new system is
- that they are non-standard. For example, SCO UNIX is not related to
- System V, Release 4 yet they try to make it sound like it is. Lots of
- people got burned by going with Xenix and realizing they were stuck
- because of the applications they bought.
-
- As for the other vendors, each has its advantages and disadvantages. I
- expect you will hear a lot about each and I am not about to go into
- details but here are some clues.
- * Don't buy Consensys unless you know what you are doing or have
- a dealer that will support you. The lower price is because of
- virtually no hand holding.
- * ESIX is a pretty good product with e-mail tech support and a
- mailing list of ESIX users to talk with
- * For a complete solution I have heard really good things about Dell.
-
- Good luck. If it matters, I am posting this from a Xenix system and the
- system in the next room is Consensys V.4. I am the administrator for these
- systems as well as an ESIX system.

-
- Although SCO Opendesktop has come a long way in the last year, I still
- feel that DELL has the best product. wimsey uses SCO ODT 2.0 and ever
- since the 'sysop' installed it, I've had problems with logging in and
- staying logged in - kind of like earlier days when wimsey used Xenix. I
- use DELL at home and have found it very good BUT I have not run it as a
- dial-in/dial-out service with ftp etc. According to people who have, it
- is very solid. I suspect that DELL has the best 386/486 Unix around -
- all things considered. They have a 30 day try out policy as well I hear.
-

-
- I'm not even going to try to summarize. There simply doesn't seem to
- be another reliable V.3 UNIX other than SCO. We have a number of them at
- work, just got a new ISC, lots of funny stuff, bum compiler, etc.
-
- For V.4 I would go with Dell (I do at home) and get the whole package
- for a cheap price compared to SCO. SCO has drivers for lots of stuff,
- has a cross compiler, has both AT&T C and their own, and is reliable.
