Configuring Windows 7 for Internet Connection Sharing

Configuring your computer and device for Internet Connection Sharing takes a few minutes. You will, however, need to meet the following requirements.

System Requirements

· Your game console must have an Ethernet port. A LAN Adapter is required for connecting to

Michigan Tech’s network via ICS.

· The computer you use for ICS must have two viable network connections; one to connect to Michigan Tech’s network and another to share the Internet connection with your game console. These ports must be wired Ethernet ports.

· For connection sharing, you will need an Ethernet cable long enough to connect your game console to your connection sharing computer.

Configuring the Sharing Computer

1. Ensure you have an active internet connection.

2. Right-click your Network Configuration icon on System Tray.

3. Click Open Network and Sharing Center.


4. Click Change adapter settings located in the left navigation pane to open the Network

clip_image006Connections window.

clip_image0085. Right-click the network adapter that will be connected to the internet and select


clip_image0106. Click on the Sharing tab of the network adapter Properties window.

7. Check the Allow other network users to connect through this computer’s Internet connection


8. Select the connection you will be using to connect to your secondary device (e.g. Xbox, Ps3, Wii)

from the networking connection drop-down list.

9. Click OK on each open window to save your changes and close the windows.

Your computer is now configured for connection of the secondary device

Howto Remove a Mailbox Export Request in Exchange 2010

Completed mailbox export requests aren't cleared automatically. You can remove fully or partially completed mailbox export requests by using the Remove-MailboxExportRequest cmdlet.

If you remove a partially completed mailbox export request, content already exported isn't removed from the .pst file. If you want to start a new mailbox export request to the same file and start with an empty .pst file, you must rename or delete the previous .pst file.

You can't use the Exchange Management Console (EMC) to remove an export request. You must use the Shell.


Use the Shell to remove a mailbox export request

This example removes the mailbox export request office\MailboxExport.

Remove-MailboxExportRequest -Identity "office\MailboxExport"

Use the Shell to remove multiple mailbox export requests

This example removes all mailbox export requests that have a status of Completed.

Get-MailboxExportRequest -Status Completed | Remove-MailboxExportRequest

How to disable ICMP echo responses in Linux

Many malicious attacks begin with a ping scan. Disabling ICMP echo requests prevents your system’s discovery with a ping.

Disable ICMP echo responses temporarily

You can temporarily disable the ICMP using the following method but this setting will be erased after the reboot.

root@lifelinux:~# echo 1 >  /proc/sys/net/ipv4/icmp_echo_ignore_all

Also, to enable the ICMP echo responses back, type the following command:

root@lifelinux:~# echo 0 >  /proc/sys/net/ipv4/icmp_echo_ignore_all

Disable ICMP echo responses permanently

You can permanently disable the ICMP echo reponses using the following method:
Edit the sysctl.conf file:

root@lifelinux:~# vi /etc/sysctl.conf

And add the following line:

net.ipv4.icmp_echo_ignore_all = 1

After that, execute sysctl -p to enforce this setting immediately:

root@lifelinux:~# sysctl -p

The above command loads the sysctl settings from the sysctl.conf.
