smokeping_install - How to install SmokePing

OOVVEERRVVIIEEWW
This document explains how to setup SmokePing at your site.

DDEESSCCRRIIPPTTIIOONN

SmokePing does not stand alone. It relies on various other tools and
services being present. Apart from a Unix OS and a working Perl instal-
lation you need the following things. The list contains the names of
the tools together with the version of the tool which I am using, and a
link for downloading the tool.

RRDtool 1.2.x
<http://oss.oetiker.ch/rrdtool/>

Just follow the installation instructions. We need this package
todo all the logging and graphing in SmokePing.

FPing
<http://www.fping.com/>

The official site seems to be a bit unmaintained. You might want to
grab the fping source from <http://packages.debian.org/unsta-
ble/net/fping> (at the bottom of the page).

Note that fping must be installed setuid root. It seems that older
versions of fping report round trip times in 0.1 milliseconds
instead of 1 milliseconds as advertised ... SmokePing tries to fig-
ure this out. It tells you when it starts ... let me know it it
gets it wrong.

EchoPing (Optional)
<http://echoping.sourceforge.net/>

You need this to run the EchoPing probes

Curl (Optional)
<http://curl.haxx.se/>

You need this for the Curl probe.

dig (Optional)
<http://www.isc.org/sw/bind/>

You need this for the DNS probe.

SSH (Optional)
<http://www.openssh.org/>

You need this for the SSH probe.

Various Perl modules (Most of these are optional)
You can get these from <http://www.cpan.org/>.

libwww-perl
The master/slave functionality introduced a dependency
LWP::UserAgent from the libwww-perl (also known as LWP)
library. Currently the module is needed even if the mas-
ter/slave mode is not enabled.

Socket6 0.11-1
Optionally installing the Socket6 module for perl enables
smokeping to check hostnames that only resolve to an IPv6
address. If you probe such hosts using ie. the FPing6 probe and
get warnings that those hosts don't resolve to an IP address,
you need to install it.

Net::Telnet
You need this for the TelnetIOSPing probe.

Net::DNS
You need this for the AnotherDNS probe.

Net::LDAP
You need this for the LDAP probe.

IO::Socket::SSL
You need this if you want the LDAP probe to be able to use the
'starttls' command.

Authen::Radius
You need this for the Radius probe.

Webserver
<http://httpd.apache.org/>

Well I wont get much into this. The important thing is, to have a
webserver which allows you to run CGI scripts. If you are using
Apache I strongly recommend using the _s_u_e_x_e_c system for running CGI
scripts. Often it is sufficient to change the _s_u_e_x_e_c binary to
setuid root and restart Apache. Using _s_u_e_x_e_c allow to run cgi
scripts under proper user accounts.

Perl 5.8.8
<http://www.perl.com>

I guess you will get away with older versions of perl. I am using
5.8.8 here and it works fine.

SpeedyCGI
<http://www.daemoninc.com/SpeedyCGI/>

SpeedyCGI speeds up CGIs written in perl dramatically by making
them memory resident and handing new request to the script which is
already running. SmokePing has been optimized for use with Speedy-
CGI. Note that you do NOT need mod_speedy, just the plain and sim-
ple speedy executable, this is the beauty of this tool it works
without touching your apache ... Otherwise you could as well be
using FastCGI or mod_perl. There is a bug in speedy with returning
error messages to the apache error log. You can find a patch in the
smokeping download area.

CGI::Carp
<http://http://search.cpan.org/~lds/CGI.pm/>

If you are using a version of Perl older than 5.8.1, you should
consider installing a newer version of CGI::Carp (must be at least
1.24, included in CGI.pm-2.82). Otherwise any error messages gener-
ated by the CGI script will not show up quite as clean as they
could in the web server error log. If you can't or don't want to
upgrade CGI::Carp, you can also set the "changecgiprogramname"
variable in the "General" section to the value "no".

IInnssttaallllaattiioonn

Once the tools listed above are in place, you can start setting up
SmokePing itself. Once the SmokePing tools are unpacked, they are more
of less ready to use. At least to the extent, that it is not necessary
to iinnssttaallll them. You may want to rename the directory to a name which
does not contain the version number of SmokePing, or at least make a
symlink, so that you can use a persistent name when referring to
SmokePing files.

In the distribution you find a number of files named _*_._d_i_s_t they have
to be edited and renamed to _*. Below you find a short explanation for
each of the files you have to edit:

_b_i_n_/_s_m_o_k_e_p_i_n_g
Make sure all the required libraries are available and the first
line of the script points to your copy of perl. Adjust the uussee lliibb
lines to point to your RRRRDDttooooll installation and to the
SSmmookkeeppiinngg//lliibb directory and edit the path of the config file to be
in sync with reality.

_h_t_d_o_c_s_/_s_m_o_k_e_p_i_n_g_._c_g_i
Edit the _s_m_o_k_e_p_i_n_g_._c_g_i analog to the _s_m_o_k_e_p_i_n_g script above. Make
sure the first line of the script is pointing to your freshly
installed copy of Speedy CGI. Store the script in a directory of
your weberver where CGIs get executed. You also have to edit the
uussee lliibb line similar to what you did to _s_m_o_k_e_p_i_n_g.

_h_t_d_o_c_s_/_c_r_o_p_p_e_r_/_*
To make the interactive graph-zoomer work, you have to place the
content of the cropper directory somewhere on your webserver and
adapt the links in _b_a_s_e_p_a_g_e_._h_t_m_l (see below).

_e_t_c_/_c_o_n_f_i_g
Create your SmokePing configuration file. The easiest is to copy
the _e_t_c_/_c_o_n_f_i_g file and work from there. Please refer to
smokeping_config for details.

_e_t_c_/_b_a_s_e_p_a_g_e_._h_t_m_l
Edit the html template to your likings. Please do not remove the
link to the SmokePing counter and my name from the template. The
content of the template will be renderd by the smokeping.cgi. This
means that all embeded links must be relative to smokeping.cgi.

_e_t_c_/_s_m_o_k_e_m_a_i_l
If you are going to use the DDYYNNAAMMIICC IP support, customize the con-
tents of this file.

Now you are ready to start smokeping:

./bin/smokeping

Once the system works, you may want to put a SmokePing startup script
into your _/_e_t_c_/_i_n_i_t_._d tree. Check out smokeping for further informa-
tion.

When you can now also open the smokeping.cgi webpage to look at your
data.
