       mrtg-nw-guide - MRTG for NetWare

S?SY?YN?NO?OP?PS?SI?IS?S

       This guide is intended to aid in the installation and configuration of

       MRTG on a NetWare server.

O?OV?VE?ER?RV?VI?IE?EW?W

       MRTG is a relative newcomer to the NetWare platform. Earlier versions

       of NetWare could not run MRTG natively for several reasons:

       +?o   Absence of NetWare OS support in the MRTG package.

       +?o   A NetWare server commandline length limitation.

       +?o   Absence of the Rateup executable (Rateup.nlm).

       +?o   A standard installation method.

       +?o   Problems with NetWare's implementation of Perl.

       Support for the NetWare OS has now been fully added into MRTG,

       beginning with MRTG release 2.12.2.

       Liberallly minded operating systems support a commandline length

       approaching 1000 characters. In such environments it was an easy matter

       to pass the sometimes high number of parameters used by MRTG's Rateup

       executable directly on the commandline. Until NetWare 6.5, NetWare had

       a commandline limit of 512 characters. This limitation was also removed

       for NetWare 6.0 by Service Pack 5. For other NetWare versions and

       earlier Service Packs, this limitation remains. To permit a 'standard'

       interface for NetWare, the Rateup executable has been modified to also

       read its parameters from a file, and the MRTG script has been modified

       to support this method on a NetWare platform.  (See New Rateup Switch)

       A Rateup NLM is now available, along with the necessary scripts to

       build it if required. See the  NetWare Support section of this document

       for further details. Additionally, mrtg.pl has been revised because of

       the unique (to NetWare) name of executables (NLM).

       The absence of a specific installation procedure has caused MRTG to

       fail in the past because the Perl script could not find or load the

       Rateup executable. The installation method supplied here will solve

       this problem for now.

       The MRTG.pl script in the 2.12.2 (or later) version of MRTG has been

       configured to suit all likely versions of NetWare able to use Perl5,

       and bypasses all of the known problems with NetWare Perl running MRTG.

P?PR?RE?ER?RE?EQ?QU?UI?IS?SI?IT?TE?ES?S

       You will need the following:

       +?o   Perl 5.8.0 for NetWare with latest Perl Updates (February, 2005 or

           later; previous versions MAY work)

       +?o   NetWare 5.1 w/ SP8, NetWare 6.0 w/ SP5 or NetWare 6.5 w/ SP2.

       +?o   A copy of the MRTG Package (v2.12.2 at time of writting)

       +?o   Three .ncf files to execute the Perl scripts at the NetWare server

           console.

       +?o   A copy of the Rateup NLM (Pre-built or compiled)

       +?o   Optionally, any NetWare supported Web Server (Netscape, Apache 1.3

           or 2.0)

       For copies of the .ncf files and Rateup NLM, see NetWare Support in

       this document.

I?IN?NS?ST?TA?AL?LL?LI?IN?NG?G M?MR?RT?TG?G

       1.  Install the latest Perl 5.8.x release on your server. See the Perl

           documentation for details.

       2.  Create the following directories:

                    SYS:/Mrtg

                    SYS:/Mrtg/bin

                    SYS:/Mrtg/contrib    (Optional for this document)

                    SYS:/Mrtg/doc        (Optional for this document)

                    SYS:/Mrtg/html

                    SYS:/Mrtg/html/images

                    SYS:/Mrtg/html/work

                    SYS:/Mrtg/lib

                    SYS:/Mrtg/logs

                    SYS:/Mrtg/translate

       3.  Copy from the MRTG package the following files:

            \bin\*        to  SYS:/Mrtg/bin              All files. See Note 1.

           Note 1: Add a .pl extension to the mrtg, cfgmaker and indexmaker

           files.  The rateup.exe will NOT be needed on the NetWare server.

            \contrib\*    to  SYS:/Mrtg/contrib/         Include sub-directories

            \doc\*        to  SYS:/Mrtg/doc/             All files

            \images\*     to  SYS:/Mrtg/html/images/     All files

            \translate\*  to  SYS:/Mrtg/translate/       All files. See Note 2.

           Note 2: For English-only language support, all \translate files

           EXCEPT Locales_mrtg may be deleted.

            \lib\*        to  SYS:/Mrtg/lib              Include sub-directories. See Note 3.

           Note 3: This will create the SYS:/Mrtg/lib/mrtg2 and ./pod

           directories.

       4.  Create copies of the three .ncf files and install them:

            *.ncf         to  SYS:/Mrtg/bin

           See NetWare Support in this document for details on how to create

           copies of these files.

       5.  See Compiling Rateup.nlm"> in this document for details on

           compiling the Rateup NLM yourself if desired.  A prebuit verion is

           available in the .\mrtg\bin directory where it must remain.

C?CO?ON?NF?FI?IG?GU?UR?RI?IN?NG?G M?MR?RT?TG?G

       +?o   Refer to Novell documentation on configuring and loading SNMP

           support on your server if this is the device to be monitored.

       +?o   Edit sys:/mrtg/bin/MakeMrtgCfg.ncf:

           replace ccccc with the GET community name for the SNMP device

           (typically 'public'),

           replace ddddd with the DNS name or IP address of the device to be

           monitored.  e.g    public@www.myserver.com, public@10.202.65.180

           Note 1: These are NOT mail addresses, they just look like one!

           Note 2: If multiple devices are to be monitored, add their entries

           to the same line:

           e.g  perl cfgmaker.pl public@www.myserver.com public@10.202.65.180

           > sys:/mrtg/bin/mrtg.cfg

           In this "Getting Started", it is 'suggested' to only monitor a

           single device.

       +?o   At the server console, run:

            sys:/mrtg/bin/MakeMrtgCfg.ncf

           This will create Mrtg.cfg in sys:/mrtg/bin.

       +?o   Edit the Mrtg.cfg configuration file created in the previous step.

           Note the following:

           It was found, when testing MRTG on a NetWare 6.5 server using a NIC

           Interface, that mrtg.cfg contained the following message:

            ### Interface 1 >> Descr: 'Intel(R)-8255x-based-Network-Connection'...

            ### The following interface is commented out because:

            ### * has a speed of 0 which makes no sense

            #

            ...

           If this occurs, edit MakeMrtgCfg.ncf and add the following

           parameter as shown:

            perl sys:\mrtg\bin\cfgmaker.pl --zero-speed=nnn public@10.202.65.180 > sys:\mrtg\bin\Mrtg.cfg

           where n?nn?nn?n is the interface speed in bits per second. For a 100

           Megabit LAN NIC, nnn = 10000000. It will be necessary to re-execute

           the MakeMrtgCfg.ncf script before continuing with this section.

           Below line 16 (*** Global Defaults), add:

            HtmlDir:    e.g  HtmlDir:  sys:/mrtg/html

            ImageDir:   e.g  ImageDir: sys:/mrtg/html/work

            LogDir:     e.g  LogDir:   sys:/mrtg/logs

            IconDir:    e.g  IconDir:  ./images

           Note 1. The HtmlDir entry specifies where MRTG will create its HTML

           pages.

           Note 2. The ImageDir entry specifies where the created graphic

           icons are placed.

           Note 3. The IconDir entry specifies where the supplied MRTG icons

           are located.  It MUST be a relative path from HtmlDir or absolute

           URL. The value shown is recommended.

       +?o   At the server console run:

            sys:/mrtg/bin/RunMrtg.ncf

           several times. By the third time it should run without showing

           error messages on the console screen.

           This should create.

           - A HTML page in the (HtmlDir) directory for each monitored device,

           - A .dat file in the (ImageDir) directory for each monitored

           device,

           - Several .png icons in the (ImageDir) directory,

           - Some log file entries in the (LogDir) directory.

           Note: If you experience a "Use of uninitialised value in split"

           error, it will be necessary to create a 'Path' environment variable

           at the server console; use the following example

            env path="SYS:\"  (The actual value is immaterial, as long as the var itself exists.)

       +?o   Edit sys:/mrtg/bin/MakeMrtgIndex.ncf. Change the indicated <path>

           shown in the following example to match the value entered for

           (HtmlDir).

            perl --noscreen sys:/mrtg/bin/indexmaker.pl sys:/mrtg/bin/Mrtg.cfg > <path>/index.html

       +?o   Create an index.html page linking the seperate device HTML page(s).

           At the server console, run:

            sys:/mrtg/bin/MakeMrtgIndex.ncf

           This will create index.html in the (HtmlDir) directory.

       +?o   Optionally, configure a Web Server to permit access to the

           directory specified in (HtmlDir) to view the MRTG graphs remotely,

           at, for example:

            http://ip_or_dns/mrtg/index.html

           A sample configuration for an Apache Webserver is shown:

            Alias /mrtg/ "SYS:/mrtg/html/"

            <Directory "SYS:/mrtg/html">

                        AllowOverride None

                        Order allow,deny

                        Allow from all

            </Directory>

       +?o   Set the property of the directory pointed to by (ImageDir), to

           'Purge Immediate'.

       +?o   Finally, read the MRTG documentation for much more detailed

           configuration/usage information.

       Welcome to MRTG!!

       MRTG can be made to run periodically by at least two means:

       +?o   Using CRON Scheduling

       +?o   Running MRTG in Daemon Mode

   C?CR?RO?ON?N S?Sc?ch?he?ed?du?ul?li?in?ng?g

       To use CRON scheduling, create a CRON Scheduler entry to execute the

       RunMrtg.ncf file on a frequency appropriate for the server environment

       and information desired. The following entry in the sys:\etc\crontab

       file will execute MRTG every five minutes:

        0,5,10,15,20,25,30,35,40,45,50,55 * * * * sys:\mrtg\bin\runmrtg.ncf

       The CRON Scheduler (cron.nlm) can be started automatically by adding it

       in AUTOEXEC.ncf or, manually loading it at the server console.

       In addition to the rateup.c and Makefile.Netware supplied with the MRTG

       release, you will also need:

       +?o   Metrowerks CodeWarrior with NetWare Support OR GCC Compiler (v3.0.3

           or later) with NlmConv Utility

       +?o   Novell LibC NDK (February 2004 or later)

       +?o   GD Graphics Library (v2.0.33 or later)

       +?o   LibPNG Graphics Library (v1.2.8 or later)

       +?o   ZLib Library (v1.2.3 or later)

       +?o   The get_ver.awk script

       +?o   A copy of the GNU build tools.    (See

           http://sourceforge.net/projects/gnuwin32/)

       The auxiliary libraries can be obtained from:

       GD Graphics Library.   (See http://www.boutell.com/gd/ )

       PNG Graphics Library.   (See http://libpng.sourceforge.net/ )

       zLib Compression Library.   (See http://www.gzip.org/zlib/ )

       Edit the Makefile.Netware file as required to match your installation

       paths; search the file for the key word 'Edit'.

       news://developer-forums.novell.com/novell.devsup.perl (Novell Developer

       Forums).

       To move the MRTG application to a volume other than SYS: you will need

       to edit the NCF scripts provided plus the MRTG[.pl] script itself in

       two places.

N?NE?EW?W R?RA?AT?TE?EU?UP?P S?SW?WI?IT?TC?CH?H

       The MRTG[.pl] script, when used on a NetWare platform, uses

       Rateup[.nlm] with the new commandline switch:

            RATEUP -f filename

       where the filename parameter can include a leading path element.

       The file format is exactly the same as that used on the commandline by

       other operating systems, including the leading path and name of the

       Rateup NLM.

A?AP?PP?PE?EN?ND?DI?IX?X

       The Appendix includes 'copies' of the following files:

       +?o   The NCF files used during MRTG configuration,

       To create copies of these files, simply 'cut and paste' into your

       favourite 't?te?ex?xt?t e?ed?di?it?to?or?r' and save under their respective names. You

       should remove the leading space from each line.
