Help Wanted Building Backbone

The South Florida DX Association is planning to install a 440-MHz packet radio backbone to accommodate the projected burden that the DX spotting system will create. The Association is seeking advice from those who have already built such a backbone so that they do not have to reinvent the wheel. If you can provide any assistance, please contact Tom Mannix, WA4YLD, at PO Box 6296, Hollywood, FL 33081.

SERVICES AVAILABLE ON TCP/IP

What can you do with TCP/IP? The standard answer says you can do electronic mail with SMTP, file transfers with FTP, keyboard-to-keyboard using TELNET, query FINGER services, etc. Actually, TCP/IP is a lot of fun! But newcomers want to know how to find other stations on the network?

The answer: by using the list below! This is a living document, one which will be regularly updated. It's being published here and in The NE TCPer, as well. And it's available on the air, in the Services directories at both ka1mf.ampr.org and nc1n.ampr.org.

So, whether you are just starting or have been using TCP/IP for a while, we hope you find the following list helpful.

Anonymous FTP File Servers

The following stations have files available on-line for anonymous FTP. To access these servers, establish an FTP session using "anonymous" as the user name and your call sign as the password. Then, browse, copy files and enjoy!

Host Name: n1gcr.ampr.org

SYSOP: Mark Hochman, N1GCR

For information, contact: [email protected]

Mark has a dual system: TCP/IP and landiine BBS (called InterVision) at his New Hampshire QTH. Like most BBSs, he carries lots (about 18 Mbytes) of IBM type programs there, some of which are ham related. Some are free and some are shareware. To get an idea of what is available, users should retrieve the file named "files.bbs" that gives a summary and size of each program available.

In particular, Mark would like to draw people's attention to his arc indows subdirectory. In this area, he has almost 3 Mbytes of Windows 3.0 software. This subdirectory also has its own "files.bbs" listing.

Host Name: k1ne.ampr.org SYSOP: Bill Becker, K1NE For information, contact: [email protected]

Bill has a number of GIF pictures and display programs. The programs are in the files subdirectory and the pictures are in the "files gif" subdirectory. K1 NE is on the air 24 hours a day.

Host Name: wa1phy.ampr.org SYSOP: Doc Willard, W1EO

For information, contact: w1eo%[email protected]

WA1PHY is located at MITRE in Bedford, Massachusetts. It is well-known as a PBBS (see the listing for bbs.walphy under "Gateways" below) and actually is a complex node with two different computers. The host wa1phy.ampr.org contains an extensive set of files available for FTP. They cover a variety of subjects of interest to TCP operators.

Note: WA1 PHY's FTP area used to be located on the bbs.walphy node. However, the bbs.walphy address is now dedicated to the packet mail gateway service.

Services Available Through SMTP

Services available through SMTP? Isn't SMTP a mail protocol? Well, yes, but the following systems each offer something special. Either the operator will offer help in the form of answers to questions or is looking for some kind of input from you. So, they are included in our list of services.

Host Name: n1gcr.ampr.org

SYSOP: Mark Hochman, N1GCR

Send SMTP Mail To: [email protected]1gcr.ampr.org

Mark is the editor of The NE TCPer. He is always looking for interesting articles. Please send anything you feel others would be interested in hearing about to [email protected]. Sending via SMTP is fine. Special arrangements for FTP submission can be made especially if you're a regular contributor.

Host Name: ka1mf.ampr.org

SYSOP; Don Hughes, KA1MF

Send SMTP Mail To: [email protected]

Don is the Amateur Radio IP address coordinator for Eastern and Central Massachusetts. Any licensed ham in those areas needing an IP address should contact Don. Send him your name, call sign, host name(s) (if special or multiple) and QTH. In addition to his SMTP address, Don can be reached at KA1 [email protected] PHY in the W0RLI-type packet mail world and also handles requests passed through a third party (eg, a current TCP/IP operator forwarding a request for a newcomer). Don also responds to mail requests for help, particularly from new comers. Don is most familiar with the IBM versions of the KA9Q software.

Host Name: nc1n.ampr.org

SYSOP: Charlie Ross, NC1N

Send SMTP Mail To: [email protected]

Charlie is the keeper of this AMPRNET services list. If you would like to contribute an entry or revise something that already appears, please send him mail. It is periodically published in several newsletters and maintained for anonymous FTP at several locations.

He's also very active within the Boston Computer Society (BCS) Amateur Radio Group. As such, any questions about the BCS can be addressed to him. He enjoys helping beginners get started particularly with the Macintosh TCP/IP software and tries to respond to questions promptly.

Host Name: ka1syf.ampr.org

SYSOP: Frank Knight, KA1SYF

Send SMTP Mail To: [email protected]

Frank is an answer man for NET/NOS and is happy to respond to user queries. He's had a lot of experience working with and adapting the source code.

Host Name: balrog.k8lt.ampr.org

SYSOP: Gary Grebus, K8LT

Send SMTP Mail To: [email protected]

Gary is the IP address coordinator for New Hampshire. Any licensed ham in that area needing an address should contact Gary. Send him your name, call sign, host name(s) (if special or multiple) and QTH. Gary's W0RLII packet address is [email protected] On the Internet, he's reachable at [email protected]. He handles third-party requests.

FINGER Services

FINGER services are among the simplest to use! Just establish a FINGER session as indicated in the description and the remote system will send you the information as a text display.

Host Name: n1ewb.ampr.org

SYSOP: Ned Kroeker, N1EWB

For information, contact: [email protected]

Ned maintains an on-line callbook server covering the first and second call areas. To look someone up, FINGER %call [email protected] For example, to get a listing on ndn, FINGER %nc1n @n1ewb. Don't forget the % sign!

Host Name: ke3z.ampr.org SYSOP: Jon Bloom, KE3Z For information, contact: [email protected]

Jon maintains the Connecticut News service. FINGER [email protected] to get an on-line listing of current noteworthy happenings.

Host Name: ka8scp.ampr.org

SYSOP: Terry Stader, KA8SCP

For information, contact: [email protected]

Terry maintains the Eastern and Central Massachusetts Update service. FINGER [email protected] to get a current on-line newsletter of area TCP/IP news and events.

Gateway Services

There are several different kinds of gateways available. The one thing in common is that they provide a "gateway" (an interface between two different communications systems). (TCP/IP "switches" often are gateways between different packet frequencies, but we will cover them in a separate listing.)

Host Name: bbs.wa1phy.ampr.org SYSOP: Doc Willard, W1E0

For information, contact: w1eo%[email protected]

One of the most heavily used nodes on the regional AMPRNET, bbs.walphy provides a gateway from SMTP into the traditional packet mailbox/BBS world. Anyone can send mail through the gateway as follows.

To send mail to the packet address [email protected] (for example, [email protected]), send SMTP mail to call°/[email protected] (for example, nc1n°/[email protected]). The gateway will convert it to regular packet mail and send it along its way.

Doc can configure the gateway to auto-forward in the other direction as well. Certain constraints apply, however. First, WA1PHY must be established as your home PBBS. Second, you must only use your call sign as your SMTP user name (eg, [email protected] rather than [email protected]). Third, to prevent backups at the gateway, your TCP/IP node must be on the air regularly. Send Doc a message if you want more information or wish to request that forwarding be established.

One final note: you can send packet bulletins (eg, to all%[email protected]) through the gateway. It is possible to pass categories of received bulletins. For details, contact Doc, however, to see all bulletins, your best bet is still to log into a PBBS using regular AX.25 packet.

Host Name: balrog.k8lt.ampr.org

SYSOP: Gary Grebus, K8LT

For information, contact: [email protected]

Gary redistributes the Internet "tcp group" mailing list. This is the mailing list of people on the Internet involved in developing and applying the KA9Q software. The list is archived in batches available for FTP at KA1MF. Gary's willing to mail this to other hosts that are up most of the time.

Gary also has an experimental mail gateway between the local AMPRNET and Usenet. He automatically routes ham-to-Usenet mail sent to user%[email protected] or hostl [email protected]
