Tip: Check out Hula, an open source calendar and mail server for Linux environments

  • Are you looking for an alternative to Microsoft's Exchange Server or Novell's GroupWise for your Linux environment? One possible option you may want to look into is Novell’s Hula project. Hula is an open-source calendar and mail server that works well in both small and larger-scale environments. It’s supported on a large number of Linux platforms, including SuSE Linux, Mandrake, Red Hat, FreeBSD, and so on, as well as on Mac OS X and Windows 2000/XP/2003. So, you have lots of choices when it comes to the operating system on which you ultimately want to run your mail server. Check out www.hula-project.org/Hula_Project for more information.

Tip: Schedule an automatic application IP address change using NoRM

  • If you need to change the IP address of a server application, you can use the Novell Remote Manager (NoRM) to schedule this change to occur at a specified date and time. Once that time comes, the change takes place automatically and the server is restarted. To set the schedule, follow these steps:
    • 1.In NoRM, click on the IP Address Management link under the Manage Server section in the left column of NoRM.
    • 2.Click on the Schedule Configuration Change link.
    • 3.Set the Date and Time for the change to occur.
    • 4.From the dropdown menu under the From heading, select the IP address to change.
    • 5.From the dropdown menu under the To heading, select the new IP address.
    • 6.Click Apply.

Tip: Get the scoop on the Novell Certified Linux Engineer 9 certification

  • Not too long ago, Novell introduced a new certification, the Novell Certified Linux Engineer (CLE) 9. According to Novell's website, the CLE 9 certification "will help you master advanced SUSE Linux Enterprise Server administration skills." After you pass the two exams required for this certification, including one Practicum exam, you'll have proven that you possess theoretical as well as hands-on knowledge of advanced Linux administration tasks in a SuSE Linux Enterprise Server 9 network environment. The CLE 9 certification is an advanced certification that requires previous Linux experience and knowledge, and therefore has the prerequisite that you must already be certified as a Novell Certified Linux Professional 9 (CLP 9). You can check out all the details at http://www.novell.com/training/certinfo/cle9/.

Tip: Recovering from a failed iManager upgrade (iManager 2.0.2)

  • If you've tried to upgrade iManager from version 2.0.2 to 2.5 and ended up with a failed upgrade, you'll have to uninstall iManger 2.5 and then reinstall it. The process is somewhat complex and involves a number of steps, including unloading Tomcat, unloading Apache services, moving a Tomcat directory from the SYS: volume to to another volume, making a backup of the Apache httpd.conf file, and removing an include statement from the file, deleting a Tomcat directory, reloading Tomcat and Apache, actually reinstalling iManager 2.5, bouncing Apache and Tomcat (reloading the services), and reinstalling non-core plugins. For detailed explanations to carry out these steps, consult TID 10097073 in Novell's online knowledgebase.

Tip: Industry thoughts on Novell Open Enterprise Server

  • If you're curious about industry opinions and other write-ups about Novell Open Enterprise Server (OES), here are some links to articles that pertain to the subject:
    • "Past And Future Meet In Novell OES," http://www.infoworld.com/article/05/04/22/17PPpreview_1.html
    •  "Novell Plans Upgrade To Open Enterprise Server," http://www.infoworld.com/article/05/04/25/17NNcypress_1.html
    •  "Novell's OES Server May Draw Business Customers," http://www.eweek.com/article2/0,1759,1778516,00.asp
    • "The Future of OES," http://www.abend.org/article.php/20050203174132363 (This article also includes a timeline through the fall of 2006 for the development of OES), and
    • "Novell's One-Two Punch," http://www.networkworld.com/nw200/2005/042505novell.html

Tip: Resolve iManager problem on Windows Server 2003/XP (Windows XP SP2/Windows Server 2003 SP1)

  • If you're using Microsoft Windows XP SP2 or Windows Server 2003 SP1 and try to install iManager 2.0.2 on either of these platforms, you'll either not be able to install iManager or you won't be able to launch iManager. This is because of a new feature in these Windows releases called Data Execution Prevention (DEP), which is aimed at increasing security by protecting the system from malicious code. This is a great idea, of course, but unfortunately, it can also prevent non-malicious code from executing, as in the case of iManager. You can, however, get around this problem by changing a Data Execution Prevention setting. First, open the System applet in Control Panel and select the Advanced tab. Next, below Performance, click Settings. Then, select the Data Execution Prevention tab, and select either Turn On DEP For Essential Windows Programs And Services Only or Turn On DEP For All Programs And Services Except Those I select. If you choose the former, DEP won't prevent iManager from installing or being launched. If you choose the latter, you'll have to specify programs, such as iManager, for which you want DEP to be turned off. Finally, click OK twice to apply the setting.
Tip: New Linux certification
  • Novell has released another new Linux certification, called the Novell Certified Linux Engineer 9 (CLE9), which focuses on advanced administration skills for SUSE Linux Enterprise Server. This certification has a prerequisite--the Novell CLP certification. Once you've gotten your CLP, you're halfway on your way to the CLE9 certification. For the complete certification path, go to the certification roadmap information page at http://www.novell.com/training/certinfo/clp/roadmap.html.  

Tip: Learn about the network discovery feature of ZENworks for Servers 6.5 (ZFS 6.5)

  • If you're new to using ZFS 6.5, the network discovery feature may seem quite confusing, even if you're an experienced network administrator. The network discovery feature of ZFS 6.5 probes the network for connected devices. Information about the discovered devices is then stored in a database you can use for a variety of purposes, including building and displaying maps of your network with all discovered devices clearly identified. This is a handy feature, because it enables you to easily keep track of what devices are connected to your network, making troubleshooting more efficient and effective. You can also control how devices are discovered and, using file-based discovery, you can appreciably limit the network traffic generated by the discovery process, leaving more bandwidth available for other important tasks.

Tip: Get the skinny on SecureLogin error codes (SecureLogin 3.5 or higher)

  • Have you ever encountered a SecureLogin error code and wondered what the error code meant? Having this information is certainly helpful for troubleshooting purposes. To find out, go to TID 10088513. This TID lists all of the possible SecureLogin error codes and their definitions. The definitions, however, aren't very detailed, so if the information you see isn't enough, you can then go to http://www.novell.com/documentation/securelogin351/index.html and choose Error Codes below the Nsure SecureLogin 3.51 Administration Guide heading. Next, choose Error Codes With Tips. You can then click Next to navigate through the error codes, or use the navigation frame on the left to select a specific error code.

Tip: When will Novell Open Enterprise Server ship?

  • Are you wondering when Novell's new offering in the server market, Novell Open Enterprise Server (OES), will ship?  So far, the word had been that it's release date was going to be around the end of 2005.  Recently, however, Novell announced that the slated release date for OES is now February of 2005, just in time for BrainShare 2005.  OES will also ship with the first support pack for SuSE Linux Enterprise Server 9 (SLES), to ensure that companies deploying OES will have the most recent updates incorporated right in OES.

Tip: Setting GroupWise notification options (GroupWise 6.x)

  • If you're running GroupWise in your network, your users may be running the GroupWise Notify program.  With Notify, when messages arrive in a user's mailbox, a message box displays for each received message.  By default, these message boxes display for 15 seconds.  You can, however, change the amount of time the Notify message box displays for each message.  To do so, right-click on the Notify icon in the system tray and choose Options.  Then, below Show Notify Dialog For, change the value to the number of seconds you want the Notify dialog box to display.  Click OK to save your settings.

Tip: New Linux certification available (SuSE Linux Enterprise Server 9)

  • A new Novell Linux certification called the Novell Certified Linux Professional (CLP) is now available.  To obtain the certification, you have to pass one practicum exam in which you have to prove your skills solving real-world problems and performing hands-on tasks.  To prepare for the certification, you can take Novell's new courses 3036 (Linux Fundamentals), 3037 (Linux Administration), and 3038 (Advanced Linux Administration).  For more information and to register for courses, go to http://www.novell.com/training/certinfo/clp/.

Tip: Updating ZENwokds for Servers (ZENWorks for Servers 3.0/3.0.0.2)

  • An interim patch called Interim Release 2 (IR 2) is now available for ZENworks for Servers 3.0 with SP2 or ZENworks for Servers 3.0.2.  You can download it by going to TID 2969668.  This TID also describes what the patch includdes, how to install the patch, and the issues it addresses.  If you previously have applied interim pach 1 (IR 1) or other patches, this does not affect your ability to install the IR 2 patch.

Tip: Sharing subfolders in GroupWise (GroupWise 5.x/6.x)

  • Do you need to share a GroupWise folder that's located below another folder?  If so, you can't share the folder by sharing the parent folder.  Instead, in GroupWise, each folder needs to be shared individually.  To share a folder, right-click on the folder and choose Sharing.  In the folder's Properties dialog box, select Shared With and then add the users or groups with whom you want to share the folder.  Click OK to save your changes.

Tip: Web seminars about SuSE Linux Enterprise Server 9 available (SuSE Linux Enterprise Server 9)

  • Are you interested in learning more about SuSE Linux Enterprise Server 9 and how it could fit into your environment?  Then check out http://register.novell.com/listings/?id=13" for a list of upcoming Web seminars that deal with this topic.  The seminars are free, but to participate, you'll have to register for the seminar(s) in which you're interested.  To do so, simply click on the Register Now link next to the seminar you'd like to attend virtually.

Tip: Resolving server SYS volume issues (NetWare 5)

  • If your NetWare 5 server displays odd symptoms, such as only a few directories displaying on the SYS volume, reports of insufficient disk space on the SYS volume by workstations when you know this to be untrue, and NLMs which should be loading but aren't, you can try the following.  In the C:\NWSERVER directory, delete the following files:  SERVCFG.TMP, SERVCFG.NBK, and SERVCFG.000.  These files hold a copy of all of the server's SET commands as specified in NCF files and at the server console, and may have become corrupted.  After deleting the files, bring the server back up and check if your problem has gone away.  Note that during the reboot, the files are re-created, and should no longer be corrupt.

Tip: Returning to the server console after an NLM hangs (NetWare 4.x/5.x)

  • When an NLM causes your NetWare server to hang, it's best to down the server properly.  However, you may not know how to return to the server console prompt in this scenario to be able to do so.  Here's what you do.  Press [Alt] [Left Shift] [Right Shift] [Esc].  Then, at the # prompt that displays, enter EIP=CSleepUntilInterrupt.  Note that this is a case sensitive command.  The message Register Changed displays on the screen.  Finally, enter G, and you should be returned to a console prompt.  Now you can down the server gracefully.  Note this doesn't fix the problem that caused the server to hang, so you still have to troubleshoot the situation.

Tip: Get the Novell Cool Solutions newsletter in your email

  • If you like Novell's Cool Solutions Web site, but don't have the time to check consistently to see if something new has been posted in your areas of interest, sign up for their email newsletter.  Once you've signed up, you'll receive an email whenever something new has been posted in the Cool Solutions areas you select.  To get the newsletter, go to www.novell.com/coolsolutions/forms/subscribe.html, enter your email address, select your areas of interest, and click Submit.

Tip: Using iManager on NetWare 6 with old volumes can be disastrous (NetWare 6)

  • Here's a tip from one of our subscribers, Erik Klausen.  There are two formats of traditional volumes: the old format and the NW6 format.  Among the differences are that the Master Boot Record spans 32 sectors in the old format, but it spans 63 sectors in the new format.  The raw server software can handle this, so you can move a volume from an old server to a new server, but iManager doesn't know the difference!  If you run iManager on a server with an old format volume, iManager will get confused and erase the volume beyond repair.  The volumes will be adjusted to the new format during an upgrade, but if the volume for some reason isn't accessible during upgrade, your old volumes are in danger.  The error can be prevented by using a special command, or by installing NW65SP2.  You can find more information on this subject in Novell's Knowledgebase, TID 10092919

Tip: Novell forums volunteer SysOPs information

  • Have you ever wondered who the technically savvy people are that help you out on Novell's technical forums?  Then point your browser to http://support.novell.com/forums/sysop_info.html.  All of the SysOPs names are listed on this page and if you click on any name, you'll get to a page with more information about that particular SysOP.  Here you can find out about the SysOP's background in networking, and often, their area of expertise.  You'll also find out where the SysOP lives so you'll have an idea of his time zone and when he's likely to be checking the forums.  Further, each SysOP's picture is posted, so when you correspond with a SysOP, you can put a face with a name.

Tip: DirXML documentation locations (DirXML 1.0/1.1/1.1a/Novell Identity manager 2.0)

  • If you're looking for documentation on Novell's DirXML product (now Novell Identity Manager), here are the links:
    • For version 1.0: http://www.novell.com/documentation/lg/dirxml10/index.html
    • For version 1.1: http://www.novell.com/documentation/lg/dirxml11/index.html

  • You can also reach the latter two via the Documentation links on their respective product pages on Novell's Web site.

Tip: Reboot fails after installing NetWare 6.5 Support Pack 2 (NetWare 6.5)

  • If you've installed the NetWare 6.5 Support Pack 2 and your server won't start after rebooting, showing an error message of "The critical component (SGUID.NLM) was not loaded or executed or is missing.  NetWare cannot function with out this component", there is a workaround.  Likely, you're experiencing this error if you're running an IBM X series server model 225, 235, or 345, although other server machines may experience this error as well.  Novell is looking into the issue, but for now, they advise to back rev NBI.NLM to the version that shipped with the Support Pack 1.1.  This should take care of the problem.

Tip: Download SUSE Linux 9.1 Personal desktop OS free (SUSE Linux 9.1 Personal)

  • You can now download unlimited free copies of SUSE Linux 9.1 Personal desktop OS from Novell's Web site.  Novell positions this OS as an alternative to the Microsoft Windows OS and also provides free training options, including a self-study kit.  You can get the free download and information on the training options at www.novell.com/training/linux/maketheswitch.html.  If you'd like to test the OS without actually installing it, you can alternatively download the LiveCD version of SUSE Linux 9.1.  This version emulates a hard drive and then runs a fully functional version of the OS.  Novell states that this version runs much slower than if you'd actually install the OS, but this way you can get a feel for what the OS is all about without going through a full install.

Tip: Checking your certification status online

  • If you aren't sure about or can't remember all the Novell certification tests you've taken over time, the scores you received, and when you've taken the exams, you can find this information online.  Go to http://www.novell.com/training/certinfo/ and in the left navigation frame, move your mouse pointer over Check Your Certification Status and then select Training & Testing History.  You'll have to log into the site with your My Novell credentials before you're taken to your personal Training & Testing History page.  This page also tells you the version of each test you've taken, which can help you with figuring out future training paths, as sometimes only certain versions of exams are still accepted for specific training paths.

Tip: Novell Small Business Suite (NSBS) 6.5 Products SP2 Overlay CD available (NSBS 6.5)

  • The Novell Small Business Suite (NSBS) 6.5 products SP2 Overlay CD is now available free for download from Novell's Web site.  This CD lets you create a new CD that installs NSBS 6.5 along with the NetWare 6.5 server Support Pack 2.  To download the software, check out TID 2969184 in Novell's Knowledgebase.  The file is approximately 554 MB, so take that into consideration relative to your download connection speed and hard drive space available.  The filename is NSBS65prodsp2.exe.  According to Novell, you'll also need the NetWare 6.5 OS Support Pack 2 Overlay CD to be able to complete an install, as the NSBS Overlay CD isn't bootable.  You can get this file through TID 2969163.

Tip: Downloading ConsoleOne snap-ins (NetWare 5.1/6.x)

  • If you need to install or re-install ConsoleOne snap-ins, you can get them from one convenient location.  Point your browser to any of the ConsoleOne product pages, such as http://www.novell.com/products/consoles/consoleone/quicklook.html, and mouse over Downloads in the left frame.  Select Consoleone Snap-Ins and you're taken to a page that contains many ConsoleOne snap-ins, ready for download.  Examples include snap-ins for ZENworks, iChain, eDirectory, and so on.
