CISCO – Connecting a New Switch to the Network

When connecting a new switch to your network you can accidentally change your current VLAN database if the new switch has a higher VLAN Trunking Protocol (VTP) revision number. To avoid this, you must clear the VTP revision number on the new switch. The easiest way is to delete the vlan database in flash memory e reload the switch. This sets the VTP revision number to 0 and you can connect the switch to the network without any problem.

Example:
cisco.switch#show vtp status
VTP Version : 2
Configuration Revision : 17
Maximum VLANs supported locally : 254
Number of existing VLANs : 10
VTP Operating Mode : Server
VTP Domain Name : doamin.com
VTP Pruning Mode : Disabled
VTP V2 Mode : Enabled
VTP Traps Generation : Disabled
MD5 digest : 0×01 0x1F 0×11 0x2B 0xF4 0×36 0x3E 0×41

LINUX – Setting up AWStats in debian etch

AWStats is a free and powerful log analyzer that works as a CGI or from command line.

AWStats is a free software distributed under the GNU General Public License.

We want to have AWStats working with Apache2 logs on Debian Etch.

0) First let’s check Apache2 Log Configuration in virtual host configuration (by default on /etc/apache2/sites-available/)

A commonly used format string to define log format is this one:

LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-agent}i\"" combined

Add this and definition in your host configuration file and then get it in use with this additional row

CustomLog /var/log/apache2/access.log combined

Save and restart Apache2

# /etc/init.d/apache2 restart

1) Now install AWStats

# apt-get install awstats

2) Configure Apache2 to include AWStats

create a new config file /etc/apache2/awstats.conf with these rows:

Now that are settings are defined you need that apache2 is aware of these config by adding this row in the end of /etc/apache2/apache2.conf

Include /etc/apache2/awstats.conf

Apply new configs:

# /etc/init.d/apache2 reload

3) Configure AWStats

Now try to call the URL http://www.yoursite.com/awstats/awstats.pl and you will get this error:

Error: SiteDomain parameter not defined in your config/domain file. You must edit it for using this version of AWStats.

When calling the URL http://www.mysite.org/awstats/awstats.pl, awstats is looking for the configuration file name after your domain name, namely here /etc/awstats/awstats.www.yoursite.com.conf.

Copy the default awstats configuration file

cp /etc/awstats/awstats.conf /etc/awstats/awstats.www.yoursite.com.conf

And edit it checking these rows:
