Pocket Ethernet should be in your toolkit


Wiremap including shield
Check whether pins on RJ45 jacks have been crimped in the correct order. Pockethernet as well tests the shield for continuity.

Advanced cable testing with only one end connected to Pockethernet. Determine how long a cable is and if it contains any short circuits, split pairs or bad terminations. Pockethernet also detects if a cable is connected to a switched-off computer or switch.
Graphical TDR
Generate a graph of signal reflections throughout the entire cable length. You can view the length of connected cables and any imperfections they may have (such as extenders or patch panels).
VLAN support
Set the VLAN tags, PCP and DEI for outgoing DNS, DHCP, HTTP and Ping requests. View tagged and untagged traffic with the traffic monitor.
Network discovery (CDP, LLDP)

View the content of CDP and LLDP messages to identify network ports more easily. If the switch port supports it, you can instantly view the connected chassis and port ID as well as the native VLAN.

Voltage detection
Find out if any pairs have a phone line or passive PoE connected to them. This allows you to detect services and to protect your network equipment.
PoE supply detection

Measure the presence and voltage of Power over Ethernet to ensure a sufficient power supply for your PoE devices.

Cable toner with customizable tones
Determine the location of cables in a wall and identify single cables in batches or at patch panels. You can set different tones and even control their volume to keep signals separate.
Bit error rate test (10/100/1000)

Real-world cable quality measurement at gigabit speeds. Measure packet length, payload and configure the number of test packets.

Port blinker
Let Pockethernet toggle the Link LED on switches and routers to easily find the cable you are looking for. Set the link speed to toggle a change of color for the port LED.
Link speed and duplex identification (10/100/1000)

Find out the Ethernet capabilities of that unused port you’re wondering about and rule out duplex conflicts.

Link establishment test (10/100/1000)
Determine whether a link can be established at different speeds and make sure the wiring is up to date for gigabit.
DHCP, DNS, Ping, HTTP tests (10/100)

Test the network connection to see if you are able to get an IP address on a port, and connect to internal servers or the Internet.

Traffic detection (10/100)
View which other devices are reachable on a specific port, as well as the type and amount of traffic that is being directed there.
Generate PDF reports

Keep a detailed, up-to-date database and log of your work just by noting locations and port IDs.

Export your results

Email reports for your own records, or share them through a phone’s OS’s native share menu with the press of a button. No more lost reports, tedious downloads from the device or manual editing.

Precision screwdriver review

Recently I came across this nifty, and inexpensive, precision screwdriver set.  If you want to order your own: http://www.amazon.com/gp/product/B07CMVYDQ2

Being an I.T. guy and an avid G.I.joe collector I am always in need of a smaller sized screwdriver set for various reasons.  ANyone who has been at a Data Center trying to get the rack ears on or off a Mikrotik cloud core router knows what I mean. Let’s dive into some uses of this particular kit.

First of all the kit comes with the following bits.
10 x “✡” (Star hexagon Screwdrivers) (T2/T3/T4/T5/T6/T7/T8/T9/T10/T15)
5 x “+” (Cross Screwdrivers) (1.0/1.2/1.5/2.0/3.0)
4 x “-” (Flat-blade Screwdrivers) (1.0/1.5/2.0/3.0)
2 x “★”(Pentagon Screwdriver) (0.8/1.2)
1 x “Y” (Y-type Screwdriver) (2.0)
1 x “▲” (Triangle Screwdriver) (2.3)
1 x “⊙” (Point Screwdriver)(0.8)
1 x Screwdriver Handle

This covers most of the small things I come across on a regular basis.  For my purposes, the cross and flat bits are what I use the most. The rest are nice to have for those one-offs.

One of the problems I always have in the GI Joe World is the back screws on the “o-ring” figures.  For those of you who don’t know there is a little screw in the back which basically holds the entire figure together.

G.I. Joe was released in 1982 and the screw can rust or otherwise become almost impossible to get out.  With this set I am able to get several screws out I have been unable to get out with other kits.

Once the screws are out you can get replacements, but getting them out is the hard part.  If the screwdriver doesn’t work you have to go to extreme measures if you don’t want to damage the figure.

The handle is easy to grip. I like the flared design to it.  Some of the other small screwdrivers don’t allow me to leverage I need. On a small screwdriver, you might not think you need leverage, because, well it’s small.  Well, there are cases where you need that extra bit of “bite”.

The bits are held in but a unique system.  I both like this and am annoyed by it at the same time.  What I like is the bits are pretty secure.  However, getting them back into the holder can be a little of a pain.

The case is small enough to have in your go bag or laptop bag. Close up, the case is about the size of a credit card.  I will be adding one into the tool bag I carry with me.
