Hummingbird Exceed is an X-Windows package that allows you to access the UNIX systems via X-Windows giving you access to X-Windows applications. There are other network utilities included such as telnet and FTP applications.
In the Hummingbird Neighborhood (located on your Desktop), several icons for X-Windows connections have been configured for you already. If you want to create new connections, follow the instructions for Configure Exceed to connect to a UNIX workstation using X-Windows located in the MMM UNIX Computing Guide.
VMWare systems will not have Exceed installed.
The telnet utility allows you to connect to UNIX systems also. This is a less sophisticated but faster way than using the Exceed X-Windows.
There are two telnet clients that are used in MMM. They include one that is bundled with the Exceed software and the telnet that comes bundled with Windows. You can also use PuTTY, which is described below in the Secure Shell section, as a telnet client.
If you have Exceed, the telnet client can be found by double-clicking on the
Hummingbird Neighborhood icon located on your Desktop. Then double-click
on the icon labeled Default VT. The following window will be displayed:
Enter the host name that you wish to connect to in the Host Name Field and click on Connect. Then you will be prompted for your UNIX username and password.
To start the basic telnet utility that is included with Windows, click on Start, select Run and type telnet host.mmm.ucar.edu. A telnet window will appear and prompt you for your UNIX username and password.
The three FTP utilities used in MMM include the Exceed FTP, WS_FTP and you can use Netscape or Internet Explorer. There is one included in Windows, but it is highly recommended that you do not use that utility. Accidentally mistyping in the Windows FTP utility will delete files.
Exceed FTP
To start the Exceed FTP, open Hummingbird Neighborhood located on your Desktop and double-click on New FTP Profile. The following window will be displayed:
Enter the host name of the system you want to connect to, your username and password in the appropriate fields and click on OK. It will prompt you to save the connection. If you select Save, then you can find the saved FTP Profile in Hummingbird Neighborhood.
When the following window is displayed, you can navigate similiar to Windows Explorer. The left side of the screen will show your Windows and UNIX files. Using this utility you can now Drag & Drop, Cut & Paste, or right-click on a file to select Download. If you do not see the file that you are looking for, select Refresh from the View menu.
WS_FTP
Since VMWare systems do not have Exceed installed, they use WS-FTP. To start it, click on the Start menu, select Programs, select WS_FTP, and click on WS_FTP95 LE.
The following will be displayed:
Enter the appropriate information such as the host name that you want to connect to, your username, and password. Click on OK to connect.
The left side shows your Windows files and the right side shows your UNIX files. To transfer files, navigate to where the file is, select it and click on the arrow buttons located in the middle to transer the file.
NOTE: Scroll down to the bottom of the Windows files to select different drives. The W: drive contains the My Documents and Desktop folders.
FTP using Netscape or Internet Explorer
You can also use one of your web browsers as an FTP client. In the Address field, use the format:
ftp://username:password@service14.mmm.ucar.edu
If the system is an anonymous FTP server, then you can enter an address similiar to the one below:
ftp://ftp.whatever.com
Outgoing FTP
If you need to transfer files between NCAR and a site outside the UCAR security perimeter, then you must use FTP in Passive mode. By default, the FTP utilities described above use passive mode as the default.
Secure Shell, or SSH, is a set of commands that allows you to make secure connections to other systems. In NCAR we use the SSH client called PuTTY. PuTTY is freely available and can be downloaded from the CSAC web page (click on Security Tools Repository).
SSH (or PuTTY) is mainly used when you are outside the security perimeter and need to connect to the gatekeeper system to gain access to MMM UNIX systems. Run putty.exe to start it. The following will be displayed. Enter gate.ucar.edu in the Hostname field and select SSH in the Protocol area. You can enter a name in the Saved Sessions field and click on Save. Click on Open.
The gatekeeper will prompt for your gatekeeper (or timecard) username and password. Once connected to gate.ucar.edu, you can type telnet hostname.mmm.ucar.edu to connect to a MMM UNIX system.
PuTTY can also be used to connect to systems other than gate.ucar.edu.

The main benefit the Domain provides is giving you access to network drives. When you are on the MMM network, this is done for you automatically through login scripts. If you are not on the MMM network, you can have access to these network resources by manually mapping network drives. The following section Accessing the Domain from another network gives more detailed instructions on configuring your system in order to map the network drives.
Open My Computer. Under the Tools menu, select Map Network Drive. The following window will be displayed:
Using the pull-down menu in the Drive field, select a drive letter. In the Folder field, enter the network drive that you wish to connect to. Below are a list of useful Network Drives.
If the Windows system is not on the Domain, then you will need to specify your Domain username by clicking on the option Connect using a different user name.
In the username field, precede your username with CIT\, which will specify your account in the CIT Domain. Enter your password in the next field and click on OK. Then click on the Finish button.
When mapping to network shares you must use the fully qualified domain name. That is, you would need to specify peepul.mmm.ucar.edu instead of peepul.
| Drive | Path | DFS |
| W: | \\peepul.mmm.ucar.edu\winusers | no |
| M: | \\peepul.mmm.ucar.edu\MMMResources | yes |
| U: | \\cit\ucar | yes |
NOTE: You may have trouble connecting to DFS Shares. DFS is a convenient way to organize network shares in one location. For example the \\cit\ucar DFS Share contains links to network shares in other divisions. If you do have trouble, you can connect to the linked shares directly. The DFS share and their links are listed below.
DFS Share \\peepul.mmm.ucar.edu\MMMResources contains links to
DFS Share \\cit\ucar contains links to
Currently this information is valid for Windows 2000/XP systems.
When you are on another network such as the RAS network, the VPN network, wireless network or from another division's network, you can still gain access to the MMM fileserver.
The way to access the MMM shares is to map network drives using the information above.
First some configuration changes may be needed. Please see the information provided below depending on which remote network you are using.
Information about configuring the RAS dial-up networking is described below.
RAS Dial-up networking is used mostly on home computers and also on NCAR laptops. After you have connected to the RAS service you can map network drives using the instructions in Mapping Network Drives.
Currently, there is a problem connecting to the DFS share \\peepul.mmm.ucar.edu\MMMResources. But you can connect to the shares listed in MMMResources, which are:
If you need to synchronize your files while using the RAS, you can right-click on the file and select Synchronize. It is recommended that you synchronize only the file that you need because you are using a slow connection.
For information regarding configuring the Virtual Private Network (VPN), see the VPN Documentation.
If you have your own Internet Service Provider and you are using the Virtual Private Network to connect to NCAR, then see the following Web pages:
Configuring and Using the VPN Client to Access a Windows Domain from a Windows 98 System
Configuring and Using the VPN Client to Access a Windows Domain from a Windows 2000 System
For information regarding configuring a wireless card, please see the Wireless Network documentation in Chapter 9 of the MMM UNIX Computing Guide.
After you have connected to the wireless service you can map network drives using the instructions in Mapping Network Drives.
Currently, there is a problem connecting to the DFS share \\peepul.mmm.ucar.edu\MMMResources. But you can connect to the shares listed in MMMResources, which are:

If the other division is on the CIT domain, then when you log into the computer, you should see all the necessary network drives that you are used to seeing. This is because network drives are mapped through login scripts.
If the division is not on the CIT domain, then you may be able to map the network drives using the Mapping Network Drives information above, but you need to select the option Connect using a different user name.
This section has not been tested.
You will need to have Virtual Private Network configured on your system. Then
you can follow the instructions above for Virtual Private
Networks.
The Scientific Computing Division has enhanced dial-up access to UCAR/NCAR networks with the addition of a CISCO AS5200 Remote Access Server (RAS). The RAS is connected to 46 telephone lines. The lines support speeds up to 56k, and can support ISDN access.
To use the new RAS, you must get a RAS account. Complete the on-line form at the following URL, and SCD personnel will contact you when your account is ready:

Enter your RAS username and password in the appropriate fields, select Save password, and click on Dial.
After this connects, you are on the UCAR network, which is on the internet. If you wish to access computers in MMM, you must specify the hostname and the mmm.ucar.edu DNS suffix (i.e. laurel.mmm.ucar.edu).
When you connect to the RAS, there will be a new connection icon in your system tray, which is located on the lower right-side of the computer screen. To disconnect from the RAS Server, put your mouse over the connection icon, right-click and select Disconnect.
If you are out of town and need to access MMM via the modem lines, use the number (800) 303-6227. The division is charged for usage of the 800 number, so use it judiciously.You can follow the procedure above Configuring RAS on a Windows 2000 System to configure a dial-up connection for the 800 number.
Local Number for Accessing the Modem
The division has an AT&T Global Net account that MMM staff can use when they travel. This will allow you to dial into a local number. The coverage is not only throughout the U.S., but also international.
To gain access to MMM systems while use the AT&T account, you need to either use the Virtual Private Network or you can connect to the Gatekeeper system via a secure shell application like PuTTY. PuTTY is mainly used to connect to the UNIX systems.
To have the AT&T connection configured for you, please enter an assist
request. You can find the AT&T access phone numbers, on the AT&T
