How To Build A Hydroponics System
Given the fact that hydroponic systems are sometimes quite expensive, and very often they
can only be ordered on the Internet, many people choose to build a hydroponics systems at
home and experiment growing plants without soil. This may begin as a hobby that could
turn into a life time occupation. Building your own plant growing independent system is not
just simple, but it is also fun. Here are the basic instructions you need to follow in order to
have a system applicable to water-loving plants.
Useful steps
In oder to build a hydroponics system you need a lightproof reservoir; this can either be a
fish tank, a bin or a bucket. If it is transparent, you'll have to paint it black given the fact that
light exposure stimulates algae growth. Once you've painted the reservoir, you'll have to
draw a line or a sign of some kind to mark the maximum water level. Then you will need a
floater ' StyroFoam is ideal for such cases. The ideal reservoirs should have the same
dimensions from top to bottom so that the floater fits better. Don't place it within the tank
until you've made the holes for the net pots.
You are going to place the net pots on the floater, so, when you build a hydroponics system
you have to trace the exact shape of the pots on the StyroFoam. Use a knife or a cutter to
do so. Since air will have to enter the reservoir, don't forget to cut another little hole at one
of the end of the floaters for the air line to run inside. Also keep in mind that plants mustn't
be too close to each other.
On the contrary, you should leave enough space between them to make sure that there is
enough light for them all. Next you have to fix the air line of the pump into the tank. When
you choose the pump, consider the reservoir dimensions. Furthermore, the air line needs to
be either on the bottom of the reservoir or in the middle, in such a way so as the oxygen
bubbles would reach the plant roots.
Top tips and recommendations
When you build a hydroponics system at home there are some dos and don'ts you have to
remember. Once you've filled the reservoir with the nutrient solution, you will need to keep
constant watch over its level. Moreover, light sources are everything. If you grow your plants
indoors and use artificial light, there are special types of lamps to be used depending on the
growth period.
For instance for accelerated growth you'd need High Intensity Discharge lamps, whereas for
dense flowers High Pressure Sodium is the best solution. Should you turn hydroponics into
a full time occupation, you'll have to think of more professional solutions when you build a
hydroponics system. Good luck!

How To Build A Simple Open-Source Distributed Protocol Analyzer
This is the way that Network General (the creator of Sniffer ') has deployed Distributed
Sniffer ' since the beginning. While the product that you are using may be from another or
Open-Source vendor,( i.e. Ethereal '/ WireShark '), this process is time honored and as
such, is considered to be 'Best Practice.'
This design is meant to assure that the NIC that is listening to the Monitor is not sending
any packets itself. The Monitor Card should have no protocols bound to itself and listens in
promiscuous mode. Additionally, the PC should be as passive as possible and not phoning
home to vendors because of unnecessary software it has loaded.
One process is to take a company's standard laptop and customize it by removing anything
that is not needed to support the role of a Protocol Analyzer. Any software that is not part of
the laptops OS requirements should be un-installed. Once the laptop has been stripped
down this way, load the Open Source Protocol Analyzer of your choice and test it.
Once testing is satisfactorily completed, save an Image of the laptop to be used to generate
other Open Source Laptop Protocol Analyzers.
System Requirements:
Pentium 4 or higher.
1GB Memory or higher.
2 NICs. One of which is 100Mbs (not Gigabit) to be used as the Monitor Card. (NOTE: This
process is not appropriate for Gigabit Monitoring.)
Remote Control Software (i.e. VNC) that supports File Transfers from the laptop acting as a
Protocol Analyzer to the PC used by the Network Transaction Analyst.

3. Two NICs:
1st NIC ' Monitor Card ' No IP bound to the card. This card just listens in promiscuous
mode. It is the one that is attached to the Monitor Port in the Switch. This should be a 100
Mbs NIC.
2nd NIC ' Transport Card ' IP is bound (static) so that this card can be used on the Intranet
to access the remote control function of the PC. This can be Gigabit if that is all that is
available.
Other Configuration Issues:
No Management Software (SMS, Radia, etc.) enabled. No management of this device other
than remote control.
Virus Protection (only if it is considered mandatory by company policy). However, this laptop
should have no email client or any other software that will want to connect to the Internet
(with the possible exception of Time Services). A Firewall rule can always be created to
enforce its isolation from the public Internet except on approved sockets.
A Time Server should be in place to keep the various Protocol Analysis Laptops in sync.
This can be an Internet source if Company Policy permits or a local Intranet source.
The laptop should not be a member of the Company Domain. One logs into the PC itself,
locally or via remote control.
All Mirrors in switches are to be bi-directional.
Consider creating a shared folder to act as a Trace File depository. This is not required, but
can be helpful as these files can easily grow too large for many corporate email policy size
limits.
Use WinZip on the Laptop to allow compression of the large trace files to speed up transfer.
