Ports for printerservices

I'm not sure which ports are exactly required, but here are a list of often used ones:

TCP 80 (HTTP)
TCP 443 (HTTPS)
UDP 137 (WINS)
UDP 161 (SNMP)
UDP 162 (SNMP Traps)
TCP 515 (LPR/LPD)
TCP 631 (IPP)
TCP 5000 (XML)
TCP 5001 (IPDS)
UDP 5353 (MDNS)
TCP 8000 (HTTP)
TCP 9000 (Telnet)
TCP 9100 (Raw Print)
TCP 9200 (IR Alerts)
UDP 9200 (Discovery)
UDP 9300 (NPAP)
TCP 9400 (Lexmark Print Port)
TCP 9500 (NPAP)
TCP 9600 (IPDS)
UDP 9700 (Plug-n-Print)
 
Normally just 9100 for RAW printing and 515 for LPD spooling. However, I know Windows clients (and I think Linux as well?) want to use SNMP to the printer to check on status, so consider 161 and 162 UDP as well.

If you need to remotely administer the printer's network interface card, you might need 80 and/or 443 as well to pull up the Web management interface.

Hyundai i10 door panel removal

Billede
Here's a little guide to how to remove the door panels on Hyundai i10. My goal was to see how I could replace the stock speakers in the car. This will be in another post when I get to it. There are two screws in the door which have to be removed. There's a little cover which easily pops open. In order to proceed you are gonna need a set of tools like this: When the screws removed, start by removing the panel near the rear mirror joystick. Use the tools above: Then you are gonna remove the window crank. I used the same tools as above to get underneath the crank, and then with some force pulled it off. Then start removal of the whole panel by starting at the bottom. There's a small gap between the panel and the door located at the bottom, which is an easy starting point. When you get around the whole panel, it should snap right off. My car had no wires attached to the panel at all. The following is pictures of the panel and speakers, which I

Hyundai i10 Subwoofer installation

Billede
This is the first time that I've upgraded any part of a car, so this post is more or less about what I learned and how I did it. I wanted more bass in my car and I definitely got it. Most of theese images are work in progress btw. I acquired the following items that I wanted to install: Blaupunkt GTB 1200 subwoofer 250 RMSW - 850W Max Pioneer GM-D8601 Amplifier 500W Continuous Power Output - 1600W Max  Pioneer 2DIN headunit - MVH-AV290BT USB/AUX/BT I started off by essentially just unscrewing stuff to see what was possible. I spend a lot of time just removing panels everywhere in the car to uncover where I could wire it all up. At the end I ended up with something like this:  1. I connected a powerwire to battery with a 40 amp fuse installed. I bought all the cables as a set similar to the picture. This included RCA-cables, power wire, ground wire, fuseholder with fuse and some connectors.  2. The power wire is pull through the so called firewall w
