Configuration and Deployment of PingertoSmokePing

Prerequisite:

Depends on rrdtool version 1.2.12 or newer version of it. Therefore it must be installed. The RRD tool is already installed on PingER machine.

Security Checks

The perl taint option -T is used in order to taint the input which the cgi will get from the user also "strict" is used.

CGI Scripts

Graph.cgi

Configuration Steps:

I changed the following path to point to 'rrdtool' installation. The path should go up to the 'perl' directory as follows:

use lib "/afs/slac.stanford.edu/package/netmon/rrdtool/lib/perl/5.8.8";
use lib "/afs/slac.stanford.edu/package/netmon/rrdtool/lib/perl/5.8.8/i386_linux24";

The problem I faced with this is that it was unable to link the dynamic library (.so) file at the run time which I ran it from Flora but when I ran it from

PingER it worked fine. The problem was due to the fact that Flora is a 64 bit machine.

I changed following link(present on line 58,252) to point to installation of Graph.cgi i.e http://www-dev.slac.stanford.edu/cgi-wrap/smokeping_graph.cgi
I changed the following relative path to GraphCache from folder containing Graph.cgi:

my $imgsrc="$HOME/pinger_smokeping/html/GraphCache where $HOME is my home directory where the project is placed.

Form.cgi

Displays the SourceSite_DestinationSite_PacketsSize_NumberOfPings(maximum) RRDs(data) available for the monitoring site or node slected from pingtable.pl by user.

Configuration Steps:

I changed the mainpath to point to the srcdest.txt file:

my $mainpath="$HOME/pinger_smokeping/SRCDEST_FILE/srcdest.txt";

where $HOME is my home directory where the project is placed.

I changed this path to point to the folder contaning the pinger.new.cf file: my $base_dir="$HOME/pinger_smokeping";
I also had to put <HTML> nad <BODY> tags to see the output correctly in the browser which otherwise gave error. This script takes two parameters as

1. src_regexp (Monitoring Site)
2. by site | node

I am facing lot of problems with this script. This script is called from the new version of Pingtable.pl but the problem is that it cannot find the

monitoring host. I think the problem is somewhere with the format of the monitorig site pingtable passes it (slac.stanford.edu) and the

*format in the text file is (pinger.slac.stanford.edu). I also tried to print the hash $NODE_DETAILS{$contents2\[1\]}\[1\] but it gave empty result.*

Pingtable.pl

I used the version provided with the distribution. I added this link to form.cgi Line 504:

$config
{URLCOLUMN0}

= "SMOKE [http://www-dev.slac.stanford.edu/cgi-wrap/smokeping_form.cgi?src_regexp=]";

I also had to chage require statement at line 96 to point it to new pinger.new.cf

require "$base_dir/pinger.new.cf";

where

$base_dir="/afs/slac/u/sg/shahryar/pinger_smokeping";

Also the path of mon-lib.pl was changed in pinger.new.cf to point to the new mon-lib.pl

These three scripts are deployed at Test server (/afs/slac.stanford.edu/g/www/cgi-wrap-bin/net/shahryar)

which I guess is not accessable from outside world. These scripts are deployed at:
