1. Getting Connected to NGS while on the Road…
Donna V. Shaw, NGS Convocation

2. “Out of the office…”
Because there are many users who must work offsite (State Advisors, Teleworkers, Contractors, Employees who are on travel), it’s necessary to make many network services available from remote locations.
Access to these services may be slightly more complex, because of security considerations, but the users will find that they have much of the functionality that they would have in the office.

3. Available Remote Services
Internet
NGS Intranet (with a valid account)
Access to files on Internal Servers, behind the NOAA TCN firewall (via ftp, telnet, etc.)

4. NOAA Dial-up Account
With a NOAA Dialup account, also called a RAS (Remote Access Server) account, users may access their NOAA or the Internet for free from any computer that has a modem and access to a telephone line.

5. NOAA Dial-up Account (continued)
To request an account, and the or local (301) phone number, contact the NGS Help Desk.
Your NOAA Dial-up login information (username and password) are the same as those you use to access your NOAA .

6. NOAA Dial-up Account (continued)
From Windows 2000 and XP machines- You can configure the dialup session by right-clicking on the Desktop “My Network Places” icon. Then scroll down to and select “Properties”, and choose “Make (Create) New Connection”.

7. What is a VPN?
A Virtual Private Network is a system which uses encryption and other security features to allow private data communications over a public network (such as the Internet). This system is comprised of hardware and software, that create a “tunnel” between authorized, authenticated hosts and users. Once this “tunnel” is established, all data that is sent across is protected from other users of the public network infrastructure.

8. Why is the VPN necessary?
Most systems on NOAA’s network are now located behind a “firewall”. Host systems behind this security hardware have private addresses that cannot be contacted by outside internet systems. NOAA refers to this as the TCN (Trusted Campus Network)

9. Systems You May Access via the VPN:
UNIX Servers
Windows Servers
