.SH "NAME"

mrtg\-nw\-guide \- MRTG for NetWare

.SH "SYNOPSIS"

.IX Header "SYNOPSIS"

This guide is intended to aid in the installation and configuration of \s-1MRTG\s0 on a NetWare server.

.SH "OVERVIEW"

.IX Header "OVERVIEW"

\&\s-1MRTG\s0 is a relative newcomer to the NetWare platform. Earlier versions of NetWare could not run \s-1MRTG\s0 natively for

several reasons:

.IP "\(bu" 4

Absence of NetWare \s-1OS\s0 support in the \s-1MRTG\s0 package.

.IP "\(bu" 4

A NetWare server commandline length limitation.

.IP "\(bu" 4

Absence of the Rateup executable (Rateup.nlm).

.IP "\(bu" 4

A standard installation method.

.IP "\(bu" 4

Problems with NetWare's implementation of Perl.

.PP

Support for the NetWare \s-1OS\s0 has now been fully added into \s-1MRTG,\s0 beginning with \s-1MRTG\s0 release 2.12.2.

.PP

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 \s-1MRTG\s0'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 \s-1MRTG\s0 script has been modified to support this method on a NetWare platform.  (See New Rateup Switch)

.PP

A Rateup \s-1NLM\s0 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 (\s-1NLM\s0).

.PP

The absence of a specific installation procedure has caused \s-1MRTG\s0 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.

.PP

The \s-1MRTG\s0.pl script in the 2.12.2 (or later) version of \s-1MRTG\s0 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 \s-1MRTG.\s0

.SH "PREREQUISITES"

.IX Header "PREREQUISITES"

You will need the following:

.IP "\(bu" 4

Perl 5.8.0 for NetWare with latest Perl Updates (February, 2005 or later; previous versions \s-1MAY\s0 work)

.IP "\(bu" 4

NetWare 5.1 w/ \s-1SP8,\s0 NetWare 6.0 w/ \s-1SP5\s0 or NetWare 6.5 w/ \s-1SP2.\s0

.IP "\(bu" 4

A copy of the \s-1MRTG\s0 Package (v2.12.2 at time of writting)

.IP "\(bu" 4

Three .ncf files to execute the Perl scripts at the NetWare server console.

.IP "\(bu" 4

A copy of the Rateup \s-1NLM \s0(Pre-built or compiled)

.IP "\(bu" 4

Optionally, any NetWare supported Web Server (Netscape, Apache 1.3 or 2.0)

.PP

For copies of the .ncf files and Rateup \s-1NLM,\s0 see NetWare Support in this document.

.SH "INSTALLING MRTG"

.IX Header "INSTALLING MRTG"

.IP "1." 4

Install the latest Perl 5.8.x release on your server. See the Perl documentation for details.

.IP "2." 4

Create the following directories:

.Sp

.Vb 10

\&         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

.Ve

.IP "3." 4

Copy from the \s-1MRTG\s0 package the following files:

.Sp

.Vb 1

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

.Ve

.Sp

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

The rateup.exe will \s-1NOT\s0 be needed on the NetWare server.

.Sp

.Vb 4

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

\& \edoc\e*        to  SYS:/Mrtg/doc/             All files

\& \eimages\e*     to  SYS:/Mrtg/html/images/     All files

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

.Ve

.Sp

Note 2: For English-only language support, all \etranslate files \s-1EXCEPT\s0 Locales_mrtg may be deleted.

.Sp

.Vb 1

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

.Ve

.Sp

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

.IP "4." 4

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

.Sp

.Vb 1

\& *.ncf         to  SYS:/Mrtg/bin

.Ve

.Sp

See NetWare Support in this document for details on how to create copies of these files.

.IP "5." 4

See Compiling Rateup.nlm"> in this document for details on compiling the Rateup \s-1NLM\s0 yourself if desired.

A prebuit verion is available in the .\emrtg\ebin directory where it must remain.

.SH "CONFIGURING MRTG"

.IX Header "CONFIGURING MRTG"

.IP "\(bu" 4

Refer to Novell documentation on configuring and loading \s-1SNMP\s0 support on your server if this is the device to

be monitored.

.IP "\(bu" 4

Edit sys:/mrtg/bin/MakeMrtgCfg.ncf:

.Sp

replace ccccc with the \s-1GET\s0 community name for the \s-1SNMP\s0 device (typically 'public'),

.Sp

replace ddddd with the \s-1DNS\s0 name or \s-1IP\s0 address of the device to be monitored.  e.g    public@www.myserver.com, public@10.202.65.180

.Sp

Note 1: These are \s-1NOT\s0 mail addresses, they just look like one!

.Sp

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

.Sp

e.g  perl cfgmaker.pl public@www.myserver.com public@10.202.65.180 > sys:/mrtg/bin/mrtg.cfg

.Sp

In this \*(L"Getting Started\*(R", it is 'suggested' to only monitor a single device.

.IP "\(bu" 4

At the server console, run:

.Sp

.Vb 1

\& sys:/mrtg/bin/MakeMrtgCfg.ncf

.Ve

.Sp

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

.IP "\(bu" 4

Edit the Mrtg.cfg configuration file created in the previous step. Note the following:

.Sp

It was found, when testing \s-1MRTG\s0 on a NetWare 6.5 server using a \s-1NIC\s0 Interface, that mrtg.cfg contained

the following message:

.Sp

.Vb 5

\& ### Interface 1 >> Descr: \*(AqIntel(R)\-8255x\-based\-Network\-Connection\*(Aq...

\& ### The following interface is commented out because:

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

\& # 

\& ...

.Ve

.Sp

If this occurs, edit MakeMrtgCfg.ncf and add the following parameter as shown:

.Sp

.Vb 1

\& perl sys:\emrtg\ebin\ecfgmaker.pl \-\-zero\-speed=nnn public@10.202.65.180 > sys:\emrtg\ebin\eMrtg.cfg

.Ve

.Sp

where \fBnnn\fR is the interface speed in bits per second. For a 100 Megabit \s-1LAN NIC,\s0 nnn = 10000000. It will be

necessary to re-execute the MakeMrtgCfg.ncf script before continuing with this section.

.Sp

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

.Sp

.Vb 4

\& 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

.Ve

.Sp

Note 1. The HtmlDir entry specifies where \s-1MRTG\s0 will create its \s-1HTML\s0 pages.

.Sp

Note 2. The ImageDir entry specifies where the created graphic icons are placed.

.Sp

Note 3. The IconDir entry specifies where the supplied \s-1MRTG\s0 icons are located.

It \s-1MUST\s0 be a relative path from HtmlDir or absolute \s-1URL.\s0 The value shown

is recommended.

.IP "\(bu" 4

At the server console run:

.Sp

.Vb 1

\& sys:/mrtg/bin/RunMrtg.ncf

.Ve

.Sp

several times. By the third time it should run without showing error messages on the console screen.

.Sp

This should create.

.Sp

\&\- A \s-1HTML\s0 page in the (HtmlDir) directory for each monitored device,

.Sp

\&\- A .dat file in the (ImageDir) directory for each monitored device,

.Sp

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

.Sp

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

.Sp

Note: If you experience a \*(L"Use of uninitialised value in split\*(R" error, it will be necessary to

create a 'Path' environment variable at the server console; use the following example

.Sp

.Vb 1

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

.Ve

.IP "\(bu" 4

Edit sys:/mrtg/bin/MakeMrtgIndex.ncf. Change the indicated <path> shown in the following example to

match the value entered for (HtmlDir).

.Sp

.Vb 1

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

.Ve

.IP "\(bu" 4

Create an index.html page linking the seperate device \s-1HTML\s0 page(s). At the server console, run:

.Sp

.Vb 1

\& sys:/mrtg/bin/MakeMrtgIndex.ncf

.Ve

.Sp

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

.IP "\(bu" 4

Optionally, configure a Web Server to permit access to the directory specified in (HtmlDir) to view the \s-1MRTG\s0

graphs remotely, at, for example:

.Sp

.Vb 1

\& http://ip_or_dns/mrtg/index.html

.Ve

.Sp

A sample configuration for an Apache Webserver is shown:

.Sp

.Vb 6

\& Alias /mrtg/ "SYS:/mrtg/html/"

\& <Directory "SYS:/mrtg/html">

\&             AllowOverride None

\&             Order allow,deny

\&             Allow from all

\& </Directory>

.Ve

.IP "\(bu" 4

Set the property of the directory pointed to by (ImageDir), to 'Purge Immediate'.

.IP "\(bu" 4
