--- name: "smokeping_install" section: "1" platform: "linux" package: "smokeping" version: "1.38-3" release: "Debian 3.1 (Sarge)" platforms: ["linux"] url: "https://new.carta.tech/smokeping_install" --- # smokeping\_install(1) smokeping\_install - How to install SmokePing This document explains how to setup SmokePing at your site.\ **Prerequisites** SmokePing does not stand alone. It relies on various other tools and services being present. Apart from a Unix OS and a working Perl installation 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. http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/pub/rrdtool-1.0.33.tar.gz Just follow the installation instructions. We need this package todo all the logging and graphing in SmokePing. http://people.ee.ethz.ch/~oetiker/webtools/smokeping/pub/fping-2.4b2\_to.tar.gz This is a special version of fping which actually builds. I have not modified the code in any way, I just fixed the autoconf setup. The original can be found on http://www.fping.com/download/fping-2.4b2.tar.gz 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 figure this out. It tells you when it starts ... let me know it it gets it wrong. http://unfix.org/projects/ipv6/fping-2.4b2\_to-ipv6.tar.gz You need this if you want to use the FPing6 probe http://www.cpan.org/modules/by-module/Socket6/ 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. http://echoping.sourceforge.net/ You need this to run the EchoPing probes 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 *suexec* system for running CGI scripts. Often it is sufficient to change the *suexec* binary to setuid root and restart Apache. Using *suexec* allow to run cgi scripts under proper user accounts. http://www.perl.com I guess you will get away with older versions of perl. I am using 5.6.1 here and it works fine. http://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 SpeedyCGI. Note that you do NOT need mod\_speedy, just the plain and simple 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.\ **Installation** 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 **install** 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 *\*.dist* they have to be edited and renamed to *\**. Below you find a short explanation for each of the files you have to edit: Make sure all the required libraries are available and the first line of the script points to your copy of perl. Adjust the **use lib** lines to point to your **RRDtool** installation and to the **Smokeping/lib** directory and edit the path of the config file to be in sync with reality. Edit the *smokeping.cgi* analog to the *smokeping* 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 **use lib** line similar to what you did to *smokeping* Create your SmokePing configuration file. The easiest is to copy the *etc/config* file and work from there. Please refer to smokeping\_config for details. Edit the html template to your likings. Please do not remove the link to the SmokePing counter and my name from the template. If you are going to use the **DYNAMIC** IP support, customize the contents 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 */etc/init.d* tree. Check out smokeping for further information. When you can now also open the smokeping.cgi webpage to look at your data. Copyright (c) 2001 by Tobias Oetiker. All right reserved.
