WARNING: Crypto package not found. Some features will fail.

June 5, 2009 – 6:45 am

That message show up when I scan conflicker in our lan.

After some google, I know the answer :

In FreeBSD :

# cd /usr/ports/security/py-pycrypto && make install

In Ubuntu :

# apt-get install python-crypto

Done.

NO more error message I guess.

Recent search for finding solution for inventory computer in the school lead me to interesting url :

From their architecture page :

“OCS Inventory NG uses an agent, which runs the inventory on client computers, and a management server, which centralizes inventory results, allow viewing inventory results and creating deployment packages.”

arsitektur ocs Install ocsinventory ng and glpi on FreeBSD

Very interesting software. After think a little bit I decide to try to install it on one of FreeBSD jail.

Here’s the steps :

1. Install database server

cd /usr/ports/databases/mysql50-server/ && make install

2. Install ocsinventory-ng

cd /usr/ports/net-mgmt/ocsinventory-ng/ && make install

3. Install logrotate

cd /usr/ports/sysutils/logrotate && make install

mkdir /etc/logrotate.d

mkdir /etc/logrotate.d/ocsinventory-NG

cd /usr/ports/net-mgmt/ocsinventory-ng/work/OCSNG_LINUX_SERVER_1.01

./setup.sh

That step will initiate checking screen.

The kernel requires the following features not present on the CPU 0:6

January 28, 2009 – 8:37 am

That message show up when I try to install Ubuntu Server 8.04.2

Looking around, the solution :

apt-get update
apt-get remove linux-server
apt-get install linux-386
apt-get install linux-server

or change linux-386 with linux-generic

will solve that problem.

December 11, 2008 – 2:15 pm

Many of us still using internet explorer as main browser due to many factor, but much more related to our worksheet display. It’s in progress to make it more compliance to other browser such firefox and opera.

Another problem came up when spyware and virus spread more easier using IE. To prevent it from spread to other host I decide to install havp in junction with installed squid.

Squid already run in port 3128 and I want to install havp in recent FreeBSD 7.1 RC1

Here’s my steps :

1.  Update ports to latest version using csup and install havp

cd /usr/ports/www/havp && make install

2. Install clamav

/usr/ports/security/clamav && make install

3. Edit rc.conf, add these lines :

clamav_freshclam_enable=”YES”

clamav_clamd_enable=”YES”

havp_enable=”YES”
