Intel thunderbolt

Hi all,

Intel has officially introduced its new high-speed Thunderbolt technology. The Thunderbolt technology provides data transfer rates up to 10Gbps. It has been first introduced into the Apple macbook. Wondering about speeds?

USB 2 = 480Mbps (half duplex)
USB 3 = 5Gbps (full duplex)
Firewire 800 = 800Mbps (full duplex)
eSata = 3Gbps (full duplex)
Thunderbolt = 10Gbps per channel, bi directional (two channels per port)

Very exciting news!

Cisco tdr command

I recently discovered a really cool command for Cisco 3560 switches.

It has a TDR (Time-domain reflectometer). It basically means you can test how long the cable is, if it has a short, pair of wires open and any other problem. More info available here from cisco.

Switch# test cable-diagnostics tdr interface g0/1
TDR test started on interface Gi0/1
A TDR test can take a few seconds to run on an interface
Use ‘show cable-diagnostics tdr’ to read the TDR results.

Switch# sh cable-diagnostics tdr int g0/1
TDR test last run on: March 01 00:09:06

Interface Speed Local pair Pair length Remote pair Pair status
——— —– ———- —————— ———– ——————–
Gi0/1 auto Pair A 20 +/- 4 meters N/A Open
Pair B 20 +/- 4 meters N/A Open
Pair C 21 +/- 4 meters N/A Open
Pair D 20 +/- 4 meters N/A Open

What are PCL and PS drivers?

PCL means printer control language and PS means postscript.

Printer control language (PCL) was released in the 1980s by Hewlett-Packard as a simpler, faster and less expensive alternative to PostScript-based laser printers.

PCL driver enables access to the maximum number of printer features, it offers limited capabilities. However, for everyday office color printing, this driver is recommended.

If you are printing color graphics or are performing desktop publishing, PS (PostScript) driver is recommended. Ideal for both Mac and Windows, this driver produces the most accurate color output.

Disable Autotuning on Vista / Windows 7 / 2008 Server

This autotuning fix is definately something to try if you are experiencing slow network/internet speeds in Vista / Windows 7 or 2008 server.

How do you run this fix:

To turn off autotuning launch a command prompt as an Administrator (type “cmd” into the Start box, right click on Command Prompt and select “Run as Administrator), then enter the following line:

netsh interface tcp set global autotuning=disabled
Restart your pc after running this command.

If you want to set this back to normal type the following:
netsh interface tcp set global autotuning=normal

Here is a link for more information regarding autotuning from Microsoft.

NTBackup is back, kinda

Good ol’ ntbackup is back again. Running vista, w7 or win 2008 server and need to recover or backup files with ntbackup? I will explain how to do this (See below).

I do like the new backup in Win 7 / 2008 server. Image / block level backups are great, especially when you can run a first big backup and afterwards only backup incrementally what has changed.

What is block based file backup? Each block in a file is examined. If a duplicate already exists, even from a different file, it is not saved. After the first backup only the delta or the changed blocks are saved in the next backup.

Here how to use ntbackup on Vista / W7 / Server 2008:

Download ntbackup from MS here

or

Copy these files from a win xp box:

Ntbackup.exe
Ntmsapi.dll
Vssapi.dll

You can find these in c:\windows\system32 of Win XP.
