Smokeping Installation

Goals

• Learn how to export flows from a Cisco router

• Learn how to install the smokeping tool

Notes

• Commands preceded with "$" imply that you should execute the command as a general user - not as root.

• Commands preceded with "#" imply that you should be working as root.

• Commands with more specific command lines (e.g. "rtrX>" or "mysql>") imply that you are executing commands on remote equipment, or within another program.

Building Smokeping

Become root user using “sudo”.

We now install smokeping. We also need to install sendmail as we need some kind of MTA on the system.

$ sudo -s
# apt-get update
# apt-get install smokeping sendmail

Given we are running Ubuntu 14.04, we will need to install a symlink to the apache2 config

# ln -s /etc/smokeping/apache2.conf /etc/apache2/conf-available/smokeping.conf
# a2enconf smokeping

I needed to fix the smokeping configuration file in the apache2 config. So, edit /etc/smokeping/apache2.conf so that the ScriptAlias line looks like this:

ScriptAlias /smokeping.cgi /usr/lib/cgi-bin/smokeping.cgi

Also, the CGI module needs to be enabled in Apache:

# a2enmod cgi

Finally, reload the Apache configuration:

# service apache2 restart

Change directory the the smokeping configuration directory:

# cd /etc/smokeping/config.d

Now edit the General file (note the first capital letter) and change the following lines:

owner    = Sysadm
contact  = sysadm@localhost
mailhost = localhost
cgiurl   = http://localhost/smokeping.cgi
# specify this to get syslog logging
syslogfacility = local5

Save the file and exit. Now edit the Alerts file (note the first capital letter) and change the following lines:

to = root@localhost
from = smokeping-alert@localhost

Save the file and exit. Restart Smokeping:

# service smokeping restart

Smokeping is now ready to be configured to monitor targets we choose.
