Networking

I have installed proftpd in my Ubuntu.

When I was downloading it was slow enough to make me searching for some answers...

Well I found some.

Here they are:


#UseReverseDNS — Toggle rDNS lookups
UseReverseDNS off
#IdentLookups — Toggle ident lookups
IdentLookups off


Placing these lines at your /etc/proftpd/proftpd.conf

you will get more speed at your file transfers.

Broadband - Switching To VOIP
By David Collins

For years we've relied on the telephone in order to keep in contact with one another, which is particularly useful for those with family in other countries or serving in the forces.

Now as technology moves on, so does our method of communicating with each other. Now the trend of communication appears to be switching to the online world, with handsets slowly being phased out by headsets and microphones.

With more of us now having access to cheap broadband technology many are now choosing to make the switch to using Voice Over Internet Protocol (or VoIP) in order to make calls.

The process seems simple enough; check your connection (and perform a broadband speed test) then download and install one of the many VoIP clients out there.

What Is Structured Cabling For Computer LAN Networks?

By Colin Yao

:: What is structured cabling?

Modern computer LAN (local area network) wiring has the concept of structured cabling.

With today's high speed networks, people realize that the networking system must be broken up into shorter chunks that allow workstation wiring to be concentrated, with each cable length short enough to support the high data rate.

Based on aforementioned reasons, structured wiring standard has been developed to help define a computer wiring system that stays within the maximum wiring distance for various LAN topologies. For example, the horizontal cable wiring length is 100 meters for 100BaseT networks.
