syscontact Vivek G Gite <[email]vivek@nixcraft.com[/email]> For your convenient, here is my /etc/snmp/snmpd.conf file. Feel free to use this file. Make sure you make backup of your existing file if you use this file as it is. Start your snmp server and test it: (a) Make sure when linux comes up snmpd always starts: # chkconfig snmpd on (b) Make sure service start whenever Linux comes up (after reboot): # service snmpd start (c) Finally test your snmp server: # snmpwalk -v 1 -c public localhost IP-MIB::ipAdEntIfIndex Step # 4 : Install mrtg if not installed Mrtg software may install during initial installation; you can verify if MRTG installed or not with following RPM command: rpm -qa | grep mrtg If mrtg already installed please see step # 5; else use rpmfind.net to find MRTG rpm or up2date command to install MRTG software: # up2date -v -i mrtg Fedora Linux user can use yum command as follows to install MRTG: # yum install mrtg Step # 5 : Commands to Configure mrtg (a) Create document root to store mrtg graphs/html pages: # mkdir -p /var/www/html/mymrtg/ (b) Run any one of the following cfgmaker command to create mrtg configuration file: #cfgmaker --global ''WorkDir: /var/www/html/mymrtg'' --output /etc/mrtg/mymrtg.cfg public@localhost or (make sure your FQDN resolves, in following example i''m using rh9.test.com which is my router FQDN address) # cfgmaker --global ''WorkDir: /var/www/html/mymrtg'' --output /etc/mrtg/mymrtg1.cfg [email]public@rh9.test.com[/email] (c) Create default index page for your MRTG configuration: # indexmaker --output=/var/www/html/mymrtg/index.html /etc/mrtg/mymrtg.cfg (d) Copy all tiny png files to your mrtg path: # cp -av /var/www/html/mrtg/*.png /var/www/html/mymrtg/ Step # 6 First test run of mrtg (a) Run mrtg command from command line with your configuration file: # mrtg /etc/mrtg/mymrtg.cfg
Note: You may get few warning message for first time; ignore them. (b) Fire your favorite web browser (like FireFox :D ) and type url [url]http://www.your.com/mymrtg/[/url] or [url]http://your-ip/mymrtg/[/url] Step # 7 Create crontab entry so that mrtg graph / images get generated every 5 minutes (a) Login as a root user or login as a mrtg user and type following command: # crontab -e (b) Add mrtg cron j |
