Windows to Linux Migration in the Enterprise? 92

Posted by Cliff from the a-mission-critical-move dept.
youngerpants asks: "There is a lot of talk at the moment about migrating applications from WIN32 to Linux. This certainly helps move the OSS movement along, however, the true test of Linux is in the enterprise. Whereas we can move applications, how can the enterprise itself (such as Active Directory to Open LDAP, Exchange Server to Sendmail and NTFS to Samba) be moved. Have Slashdot readers used any applications or followed any strategies to migrate their enterprise? How would you tackle an obviously risky migration?"

    • Realistically this just doesn't work because the overall best integrated system is still windows. Linux may be cheaper on a per seat basis but when you consider how many people are required to keep the systems running it becomes less and less clear that Linux us the way to go.
      • Are you claiming that Linux boxes require more support than windows boxes?
        That certainly has not been my experience.

        Could you please explain what you were trying to say in the previous post?
      • i cant agree with you on this one. at worst linux would require the same amount of people required to run windows system. it also helps that linux is much better at being remotely administrated (SSH/Commandline is much more efficient than Terminal Services). only reason i can think of linux requiring more people is because the admins arent properly trained.

    "Active Directory to Open LDAP, Exchange Server to Sendmail and NTFS to Samba"

    I understand the gist of your question, although I don't think you understand it yourself. None of your examples actually discuss the one thing the enterprise is interested in: "Functional Parity"

    AD to OpenLDAP doesn't go, because OpenLDAP is just a directory protocol -- I wish people would start to understand that. There is no directly usable management interface, no business logic, no nothing. It is just a protocol....

    Comparing Exchange Server and Sendmail earns you a good thwapping over the head in my team -- maybe Exchange Server vs. Open-Exchange, but again you are comparing the wrong things. Finally, go stand in the corner for comparing NTFS with Samba.

    I usually don't complain about Ask Slashdot type stuff, but this takes the cake. Go learn something about IT before you ask stupid questions.
    • Oh, and to answer the real questions:
      1. Active Directory to Novell eDirectory, although that doesn't really give you much. No real Open Source functional alternative.
      2. Exchange server to Open-Xchange [open-xchange.org]
      3. NTFS to perhaps XFS or Reiser, orOpenAFS [openafs.org], although OpenAFS is really lots better, and has tons more functionality

      Have a lot of Fun!

      • Actually really here you go 1. Active Directory to Samba 4 2. Exchange to Exim, Postfix, Sendmail, Qmail, or OpenXchange - pick one. 3. NTFS to Reiser.
        • Sorry, but Samba does not deliver functional partiy (i.e. sam functionality) to Active Directory. It may be somewhat similar, and it may be better in some ways, but it is not a good replacement. Neither are Exim, Postfix, Sendmail or QMail - all SMTP deamons. they don't even offer your basic IMAP/POP/ Calendaring, etc functionality. And I did actually mention NTFS to Reiser, but think AFS is more what the poster had in mind.

        As for "chilling a little", I met a customer last week, who simply did not want to talk open source, because some clueless critter of an "IR Consultant" came in some time ago shouting something similar. "Get rid of all your Microsoft products! They are EVIL!" now, this customer is a relaxed dude, so went like "okay, but I replace it with what?" and something similar to the above list came up. For most people that list is simply unacceptable -- they don't *care* what they run, as long as it works. So someone coming around that can't even tell the difference between Exchange and Sendmail, and states "rip out all your groupware, calendaring, forums, imap, mail, pop, webmail, and some CRM functionality, and instead I give you Sendmail....it's FREE!" does not really impress.

        Customer now thinks Open Source people are clueless freaks, and any mention of this stuff is taboo. I see this *all the time* and it really gets me upset.

            nssldap, pamldap and MS Services for Unix...

            Nssldap will have to be recompiled for schema mapping, since AD doesn't follow a standard LDAP schema. Last I checked FC2 and FC3 already had compiled nssldap this way, so no recompile was necessary.

            MS Services for Unix is needed to modify the AD schema and for a couple of added screens in the admin tools for AD, to allow Unix attributes to be added.

            If you want to be able to change passwords from *nix, you will need to setup SSL, since password changes can only occur over SSL in AD.

            I disagree that few *nix apps take advantage of Kerberos. Indeed, Samba and OpenLDAP, both mentioend here, do. OpenSSH, Cyrus IMAP, Netatalk, fetchmail, and many popular others do too. But you are right that it is far from universally implemented & many now choose to just run most traffic over SSL instead.

            My two cents on what you didn't ask about: I, like you, am impressed that you basically get kerb for free for most traffic from a windows server. However, I hate MS for the way they did this. They use non-standard, undocumented features that prevent non-MS systems from actually being interoperable with them. Even the MIT Kerberos team has accused them of trying to embrace & extinguish. I suspect that some (though certainly not all) of the lack of Kerberos on *NIX has to do with this.

              I agree that the way that MS changed Kerberos to add authorization information is intensely frustrating, but I think that adding authorization information is the right thing to do. Trouble is, it's a hard problem to come up with a reasonable authorization infrastructure. MS had one already. The rest of the world doesn't agree on

    As much as I love open source and think it provides tremendous value to organizations, I have to realistically evaluate any large migration and observe two obvious points:

    1) It's different. There will be people who will not want to see it succeed. You will need to PROVE that the functionality provided is SUPERIOR and that the cost of migrating is overcome by the reduced ongoing TCO.

    2) Is your organization ready to provide the level of support it has become accustomed too? Are you a MS Enterprise or Select customer? You need to prepare for the fact that to some extent the warm fuzzy blanket of misleading comfort is being pulled away from the organization.

      Yes. And when 50% of the company is on linux, then what?

      The key is to make your applications fully web-based and be os-agnostic. There are three main reasons companies even look to replace their existing systems:
      * Cost, short term and long term.
      * Increased functionality.
      * Effective staffing.

      Right now linux provides visible short-term cost. Also, it can provide some long-term cost saving but that's more fuzzy.

      On functionality, the gaming world will tell you going away from windows is a step back. I think you gain some and you lose some, so wash.

      Staffing: You need fewer people but you have to pay them more.

    The point of my post is not to denigrate Linux. I am generally a Linux advocate, and will still deploy it wherever it is practical (practical being the operant word here). The issue, however, is that much of these services are inside of niche markets where it doesn't make sense for the vendor to develop Linux support. Others are very bleeding edge and not commercially supported. If you don't have a very large IT department to support the services that you want to run, they're nearly useless -- that is, unless you've got gobs of free time on your hands.

    OTOH; if you're rolling a custom app (and thus already have the staff you need), need a webserver, or a database backend, Linux may be an excellent choice. One way to look into it is to find out how Linux is most widely deployed and supported as a solution (ie web servers, database backends, etc). If you go the other way, choosing whatever solution you find that's "out there", you may find yourself in a heap of trouble -- looking for a new job. I supppose that this applies to all software, commercial or otherwise. Always ensure that you can support it...but it's something that one has to be especially cautious about when getting into a bleeding edge F/OSS package that is new enough where there is either no commercial support, or inadequate support for your needs...and unfortunately, there are currently quite a few of these out there.

        It is. The original poster also implied that Windows is "enterprise class". This seems to just be generally implicit. You and I may or may not like Microsoft operating systems, but it doesn't change the fact that this is what they're in place for. You can see past your own agenda, right?

          Seriously, the concept of "shrinkwrapped" software doesn't go with Enterprise -- a lot of customization and integration will need to be done. "QuickBooks" and its kin won't cut it. That's what I think of when "shrinkwrap" is mentioned. You are not going to find ADP software at your local computer store!

          Now, if you are ARE talking enterprise accounting, the same number of solutions are going to be available on UNIX based platforms.

    I've always been curious about this. I love Linux, but one of the areas where I think it is sorely lacking is in file system permissions flexibility. For example, if I had a folder and wanted the following in Linux, how could I do it?

    MKTG group = rwx
    DEV group = r
    EXEC group = r
    ADVERT group = rx
    ADMINS group = rw

    Is there a way to do this in Linux? I have no idea. It has always been my understanding that I'm stuck with UGO and sitcky bits for permissions. Is this entirely true or is there another way.

    • I've always been curious about this. I love Linux, but one of the areas where I think it is sorely lacking is in file system permissions flexibility.

      I'm hoping that one of the things that you love about Linux is its flexibility...most distributions can grow far beyond their packaging. :)

      I believe that you're looking for ACL support (Access Control Lists). Check this [sourceforge.net] out. Also, just do a google search for Linux ACL's. There are lots of projects in development, and considering how long these have bee

    • You need to look into Access Control Lists. That will allow you do have much finer-grained file access controls.

    • Here is a guide for POSIX ACLs in Gentoo [gentoo-wiki.com]. From there, you should be able to do it easily in any other distro (in case you are not a Gentoo user). Basically, you get to recompile the kernel if POSIX ACLs for your filesystem are not already compiled in and then you have to remount your filesystems with the acl flag enabled. For bonus points, you should also install your distro's ACL manipulation tools. ;)

      The HOWTO that I linked to has a more detailed explanation of how to do it.

    • To go along with the other posters, yes ACLs give you this control over permissions and I believe they are included by default in the 2.6 kernel. Certainly Fedora Core 3 and RHEL 4 include them.
  • I always see comments on these stories like, "zealots tell people to switch and can't back it up". Perhaps what the community needs to realize is, apart from companies who know what they are doing and can facilitate an effective transition, maybe it is best that companies do not do an abrupt shift from Windows to Linux. I am a vehement Linux supporter, but I realize that the transition may not be good for some people/companies. My parents both use Windows. I know that giving them a Linux box probably is

  • If you have a lot of apps that simply can't be migrated, or there's no way to safely and gradually perform the migration, it may be best to hold off or look into a partial migration. The ultimate goal is to solve problems and/or save money.

    Samba for me has been a very good file server, performing seemingly much faster than I've seen with Windows servers, with the flexibility to do some very interesting and unusual setups.
