http and (ip.addr <= 10.80.211.142 and ip.addr >= 10.80.211.140)

tcp.port == 80 and (ip.addr <= 10.80.211.142 and ip.addr >= 10.80.211.140)

The above will filter out all packets with an ip address between 10.80.211.140 and 142 with a TCP port of 80.

If you have redundant connections to the internet via different internet service providers you will need to contact your Regional Internet Registry to obtain a range of IP addresses. You can then have single or multiple IP ranges broadcast by your ISP as your IP block thus providing you with a multihomed solution. When multihoming takes place you can have one IP address used with two interfaces or ISP connections. With the use of a routing protocol, most commonly BGP, the end-site (your ISP) announces your assigned IP address space to its upstream links. When one of the links fails, the protocol notices this on both sides and traffic is not sent over the failed interface / link any more. You must obtain your own public IP address range or block of IP addresses in order to take advantage of multihoming.

If you need your own IP addresses for your business or otherwise you’ll need to contact one of the five Regional Internet Registries, RIRs.

• American Registry for Internet Numbers (ARIN). The ARIN service region includes Canada, many Caribbean and North Atlantic islands, and the United States.
• LACNIC’s geographical service area includes ARGENTINA, MEXICO, PERU, BRAZIL for a complete list please google LACNIC.
• RIPE NCC’s geographical service area includes BULGARIA, FRANCE, GREECE, ITALY, for a complete list please google RIPE.
• AfriNIC’s geographical service area includes ALGERIA, ETHIOPIA, LIBERIA, SUDAN for a complete list please google AfriNIC.
• APNIC’s geographical service area includes AFGHANISTAN, AUSTRALIA, NEPAL, VIETNAM for a complete list please google APNIC.

We will explore the process of “how to get your own IP address” with ARIN. While I haven’t ever tried the other RIRs I’m sure the process is similar for the other Regional Internet Registries.

Step 1: Requirements
First thing you need to ask yourself is “do I meet the requirements necessary to obtain my own IP addresses”? This really isn’t hard to answer. If you truly plan to use the IP addresses it’s not hard to get them and keeping them is more of a reporting function that anything else. The four basic things you’ll have to do are:
provide data showing efficient utilization of all previous assignments (unless you don’t have previous assignments)
provide data demonstrating a 25% utilization rate of the requested block immediately upon assignment
provide data demonstrating a 50% utilization rate of the requested block within one year
provide verification your organization intends to multi-home using the requested block (a network diagram will suffice)

Step 2: Submit Request

The next two forms you’ll need to fill out to procure your IP address or IP addresses are the:

POC https://www.arin.net/resources/templates/poc.txt this is to Register a Point of Contact (POC) record in ARIN’s database.
Organization https://www.arin.net/resources/templates/org.txt this is to Register an Org ID in ARIN’s database.

Step 3: Verification
Okay now ARIN has the data and will make sure it’s all filled out right. So don’t waste time here.. it’s a simple double and triple check of the form. Make sure its filled out right before you submit your request to get IP addresses.

Step 4: Review Process
ARIN will respond to requests within two (2) business days. We may request additional information. For each question and response cycle, ARIN will respond within two (2) days. If you do not reply within ninety (90) days, the ticket will be closed. Just don’t get the forms wrong. Be sure to include all the needed information to obtain your IP addresses.

Step 5: Officer Certification
Prior to approval, ARIN will send an e-mail with all data received on the request to an officer of the company for certification.

Step 6: Request Approval
ARIN notifies the submitter of request approval, via e-mail. The approval is good for ninety (90) days. If your organization does not follow up on the approval within that time, you will need to resubmit your request.

Step 7: Fees & Registration Services Agreement
ARIN charges a one-time registration fee for each resource assignment, based on the size of the assignment. Double check this data but last time I checked here was the going rate for Initial IP Allocation Space Assignment

First lets look at the windows operating system and how to find out what process is using what port.

Open your command prompt and type in netstat -ano  this will list all processes ID and what port it is running or listening on. To open the command prompt click start -> run -> cmd and hit enter. This will open the command prompt. netstat -ano will output as seen below

Type netstat -ano to list processes running and the PID number

Find the port you’re inquiying about and take note of the PID. Now that you have the PID number (located to the left side of the command prompt) you can open up the task manager to tie that PID to a process / program.

Just hit control + alt + del then click task manager or you can right click the bottom task bar and select task manager from the list.  Once task manager is open you’ll need to tell it to display the PID. To do this open task manger and click -> view -> select columns -> and select PID

Now you can see the PID and the corresponding program / process associated with it.

Finished with windows.. on to UNIX!

How to determine what process is listening on a port in Unix is so much easier.

Let’s say we want to find our what process is tied to port 53.

First, use the following command to find if the port is is use or not
netstat -an | grep 53

#Then, use the following command to find which process is using the port
fuser -n tcp 53
This will return something like ’53/tcp: 5006′.
it shows pid.

After that, we can find the full process information.
ps -ef | grep 9113

If you know shell you can use the below in a shell script to put all these step together

#!/bin/sh
status=`netstat -an |grep $1`
if [ "$status" == "" ]; then
echo “port $1 is free”
exit
fi
ps -ef |grep `fuser -n tcp $1`

Or if you’re running linux download lsof
lsof -i :53

or

lsof -i :1226

Or you and use grep

lsof | grep [process name]

Before we start I just want you to know about this free online backup program from an icon in the backup industry.

Recuva – freeware file recovery that can’t be beat. I’ve used this several times already and it’s a great file recovery software. Works well and is easy to use. Intuitive user interface so you don’t need to be super geek to get your lost file back. Fairly high sucsess rate but not 100 percent. If you can’t find it with recuva I recommend File Recover from PC Tools. PC Tools is a great option for file recovery with the main software you want to use being called File Recover.  PC Tools Software is a global leader developing products to protect the privacy, security, performance and stability of Windows computer users.

So lets get started with Recuva. Here is the main list of instructions on how to use recuva software. This information is spread across the recuva site but I figured it would help you guys if I pulled it all together into one document here. So after you download recuva you can come back here for instuctions.

Before you start Recuva:

Take these precautions to get the best results from Recuva:

• Quit any applications you’re not using and don’t need.
• If you are trying to recover files from a media card, stop using that card immediately.

Here’s the fastest way to get your files back:

1. Start Recuva in Wizard mode. If the Wizard doesn’t appear, click the Options button, and then click Run Wizard.
2. On the Welcome to the Recuva Wizard page, click Next.
3. On the File Type page, select the type of files you want to recover, then click Next. If you’re not sure what type of files you’re looking for, select Other.
4. On the File Location page, select the location where you want to search, and then click Next.
5. On the Thank You page, click Start. Recuva displays the progress of the scan, and then shows its search results in the main window. If the file(s) you’re looking for aren’t in the list, see below.
6. Select the check boxes beside the file or files you want to restore. The color of the dot next to the file name indicates your chances for a successful recovery (green for excellent, orange for acceptable, and red for unlikely):
7. Click Recover. Select a destination for the recovered files (ideally, on another drive). Click OK.

If Step 5 did not locate the files you were seeking, close Recuva and run Steps 1 to 4 again. On the Thank You page, select Enable Deep Scan and then click Start. This advanced scan will take much longer (possibly hours).

Quick Start: If you know the file names

You can speed up Recuva’s search and recovery if you know all or part of the name of the file you’re looking for:

1. Start Recuva in Advanced mode. If the Wizard appears, select Do Not Show This Wizard on Startup and then click Cancel.
2. In Recuva’s main window, type all or part of the file name into the Filename or path box. Select the location you want to search from the drop-down box at left, and then click Scan.
3. Recuva displays the progress of the scan, and then shows its search results in the main window. If the file(s) you’re looking for aren’t in the list, see below.
4. Select the check boxes beside the file or files you want to restore. The color of the dot next to the file name indicates your chances for a successful recovery (green for excellent, orange for acceptable, and red for unlikely):
5. Click Recover. Select a destination for the recovered files (ideally, on another drive). Click OK.

If Step 4 did not locate the files you were seeking, select Deep Scan in the Options dialog box on the Actions tab. Run Step 5 again. This advanced scan will take much longer (it can take hours).

Issues after running Recuva

Now that firefox is installed we are going to make it 10 times faster by telling firefox it is okay to open up multiple connects to the web site we are visiting. So it’s like having 10 browsers working for you to open one web page! This works especially well when uploading files (pictures, email attachments etc) to a websites like hotmail, yahoo mail and flickr etc.

Open firefox and in the address bar type: about:config

Now in the filter filled type in “network” or just search for network.http.pipelining – okay now change network.http.pipelining to true by clicking it. see photo below. This will allow pipelining and is step one in how to make firefox faster.

Normally Mozilla Firefox only sends one or two tunnels to the website you are visiting – Changing the following setting will allow 10 tunnels thus allowing you to view the site faster. This works good for large sites like youtube, yahoo, google, and I noticed my webmail is a lot faster to. Please don’t set it any higher than 10 because it will hurt small sites that can’t handle tons of request.

That’s all! wasn’t that easy! that’s how to make firefox faster! well what we really did was allow firefox to pipeline multiple connections to websites thus using more of your bandwidth and the site which you are connecting to so keep maxpipeline set to 10.. anything higher is bad mojo.

If you use a proxy server then you can also change the following setting to allow pipelining to a proxy. Firefox faster with a proxy!

Now what are you waiting for? Download firefox now! The download is from google and includes firefox and the google tool bar.

Make sure you don’t have a load of programs running in the background, particularly ones that use an Internet connection. P2P programs like Limewire and Kazaa often cause extreme bogging and slowness. Right click you task bar and choose task manager – here look at your performance and research each item listed under the processes tab on google killing anything you are advised to kill via the search engine. If you are unsure then leave it alone.

Delete any temporary Internet files and perhaps increase the cache sizes. Also you could try firefox I think it’s faster!

Purchase and/or re-seat another cat5 cable and try that out. Bad connections will cause slow connection speed.

Run a tracert to several websites to determine the latency – you will find the latency to be different between different sites etc you can use this to judge where the bogging it taking place. – click start – run – type CMD – then type at the command prompt “tracert yahoo.com” and hit enter.. no quotes of course.

Last but not lease check the duplex and speed setting of your PC. If you are connected to a hub you need to set it to half duplex 10 mpbs – you are connected to a switch or modem you want full duplex 100 mbps

Here is how you check -

1. Clickon the Startbutton.

2. Right Clickon My Computer.

3. Clickon Properties.

3. Clickon the Hardwaretab.

5. Then Clickon the Device Managerbutton.

6. Clickon the Plus signnext to Network Adapters.

7. Right Clickon your ethernet card. Then Clickon Properties.
8. Clickon the Advanced tab – if you don’t have one then you are SOL
9. In the advanced panel there will be a list of settings look for something like connection type, line speed, or duplex mode. Remember that you’re trying to change the speed setting to 100 mbps and full duplex
