Important Things 1999

Usually, I use VPN to update my Outlook. After succeed dial-up, the policy of company will prohibit you to visit lots of websites, such as youtube, google word, and all vicious websites he thinks. How to visit those websites and update Outlook at the same time?

This is my VPN solution:

1. Host OS: Ubuntu Linux
2. Guest OS: Microsoft Windows in VMware Workstation/Server for Linux(If you are VCP of VMware, they will send you a formal Workstation license after passing training class and VCP-310 test).
3.  CISCO VPN and Outlook software is installed in guest OS(Windows).
4. Using Linux to visit website which is prohibitted by the company’s firewall.
5. Using Windows to dial VPN, and setup VPN tunnal, Outlook will using this tunnal to receive and send email.

Since tunnel is setup by Windows, no Ubuntu, so Ubuntu can do anything without considering firewall of company. This will be helpful when you work at home.

Internet access network can be ethernet or wireless, because Windows(Virtual machine) don’t care about it, setup of physical line is job of Ubuntu.

If this article help you, I will be pleasure to hear from you.

if you can’t open wireless connection of Internet, you should try this again.

Mannul Network Configuration –> Unlock –> wireless configuration –> re-fill SSID with correct WPA2 key –> OK

Notes: You should have your wireless device recognized before doing this.

Three posts of today were written under Ubuntu 8.04 using wireles connection.

I have tested a lot of times for Ubuntu wireless configuration on DELL Latitude D420.

It’s very strange that Ubuntu cann’t recognize hidden broadcast SSID althought I had input correct SSID and WPA2 key.

I didn’t think this would be a problem, even tried NDIS(deleted later), but after I changed my SSID configuration two days late, the error was gone, I could visit Internet after DHCP.

Hidden SSID problem wasted my two nights to solve and verify.

Maybe Ubuntu next version(V8.10) doesn’t have this problem, but I have no schedule to upgrade, V8.04 is good enough for me.

Stable is the first thing.
