INTRODUCTION

DECWRL is a mail gateway computer operated by Digital's Western Research

Laboratory in Palo Alto, California. Its purpose is to support the interchange

of electronic mail between Digital and the "outside world."

DECWRL is connected to Digital's Easynet, and also to a number of different

outside electronic mail networks. Digital users can send outside mail by

sending to DECWRL::"outside-address", and digital users can also receive mail

by having your correspondents route it through DECWRL. The details of incoming

mail are more complex, and are discussed below.

It is vitally important that Digital employees be good citizens of the networks

to which we are connected. They depend on the integrity of our user community

to ensure that tighter controls over the use of the gateway are not required.

The most important rule is "no chain letters," but there are other rules

depending on whether the connected network that you are using is commercial or

non-commercial.

The current traffic volume (September 1989) is about 10,000 mail messages per

day and about 3,000 USENET messages per day. Gatewayed mail traffic has

doubled every year since 1983. DECWRL is currently a Vax 8530 computer with 48

megabytes of main memory, 2500 megabytes of disk space, 8 9600-baud (Telebit)

modem ports, and various network connections. They will shortly be upgrading

to a Vax 8650 system. They run Ultrix 3.0 as the base operating system.

ADMINISTRATION

The gateway has engineering staff, but no administrative or clerical staff.

They work hard to keep it running, but they do not have the resources to answer

telephone queries or provide tutorials in its use.

They post periodic status reports to the USENET newsgroup dec.general. Various

helpful people usually copy these reports to the VAXNOTES "gateways" conference

within a day or two.

HOW TO SEND MAIL

DECWRL is connected to quite a number of different mail networks. If you were

logged on directly to it, you could type addresses directly, e.g.

To: strange!foreign!address.

But since you are not logged on directly to the gateway, you must send mail so

that when it arrives at the gateway, it will be sent as if that address had

been typed locally.

* Sending from VMS

If you are a VMS user, you should use NMAIL, because VMS mail does not know how

to requeue and retry mail when the network is congested or disconnected. From

VMS, address your mail like this:

To: nm%DECWRL::"strange!foreign!address"

The quote characters (") are important, to make sure that VMS doesn't try to

interpret strange!foreign!address itself. If you are typing such an address

inside a mail program, it will work as advertised. If you are using DCL and

typing directly to the command line, you should beware that DCL likes to remove

quotes, so you will have to enclose the entire address in quotes, and then put

two quotes in every place that one quote should appear in the address:

$ mail test.msg "nm%DECWRL::""foreign!addr""" /subj="hello"

Note the three quotes in a row after foreign!addr. The first two of them are

doubled to produce a single quote in the address, and the third ends the

address itself (balancing the quote in front of the nm%).

Here are some typical outgoing mail addresses as used from a VMS system:

To: nm%DECWRL::"lll-winkin!netsys!phrack"

To: nm%DECWRL::"[email protected]"

To: nm%DECWRL::"[email protected]"

To: nm%DECWRL::"[email protected]"

To: nm%DECWRL::"[email protected]"

* Sending from Ultrix

If your Ultrix system has been configured for it, then you can, from your

Ultrix system, just send directly to the foreign address, and the mail software

will take care of all of the gateway routing for you. Most Ultrix systems in

Corporate Research and in the Palo Alto cluster are configured this way.

To find out whether your Ultrix system has been so configured, just try it and

see what happens. If it doesn't work, you will receive notification almost

instantly.

NOTE: The Ultrix mail system is extremely flexible; it is almost

completely configurable by the customer. While this is valuable to

customers, it makes it very difficult to write global instructions for

the use of Ultrix mailers, because it is possible that the local changes

have produced something quite unlike the vendor-delivered mailer. One of

the popular changes is to tinker with the meaning of quote characters (")

in Ultrix addresses. Some systems consider that these two addresses are

the same:

[email protected]

and

"site1!site2!user"@host.dec.com

while others are configured so that one form will work and the other

will not. All of these examples use the quotes. If you have trouble

getting the examples to work, please try them again without the quotes.

Perhaps your Ultrix system is interpreting the quotes differently.

If your Ultrix system has an IP link to Palo Alto (type "/etc/ping

decwrl.dec.com" to find out if it does), then you can route your mail to the

gateway via IP. This has the advantage that your Ultrix mail headers will

reach the gateway directly, instead of being translated into DECNET mail

headers and then back into Ultrix at the other end. Do this as follows:

To: "alien!address"@decwrl.dec.com

The quotes are necessary only if the alien address contains a ! character, but

they don't hurt if you use them unnecessarily. If the alien address contains

an "@" character, you will need to change it into a "%" character. For

example, to send via IP to [email protected], you should address the mail

To: "joe%widget.org"@decwrl.dec.com

If your Ultrix system has only a DECNET link to Palo Alto, then you should

address mail in much the same way that VMS users do, save that you should not

put the nm% in front of the address:

To: DECWRL::"strange!foreign!address"

Here are some typical outgoing mail addresses as used from an Ultrix system

that has IP access. Ultrix systems without IP access should use the same

syntax as VMS users, except that the nm% at the front of the address should not

be used.

To: "lll-winken!netsys!phrack"@decwrl.dec.com

To: "postmaster%msp.pnet.sc.edu"@decwrl.dec.com

To: "phrackserv%CUNYVM.bitnet"@decwrl.dec.com

To: "netsys!phrack%uunet.uu.net"@decwrl.dec.com

To: "[email protected]"@decwrl.dec.com

DETAILS OF USING OTHER NETWORKS

All of the world's computer networks are connected together, more or less, so

it is hard to draw exact boundaries between them. Precisely where the Internet

ends and UUCP begins is a matter of interpretation.

For purposes of sending mail, though, it is convenient to divide the network

universe into these categories:

Easynet Digital's internal DECNET network. Characterized by addresses

of the form NODE::USER. Easynet can be used for commercial

purposes.

Internet A collection of networks including the old ARPAnet, the NSFnet,

the CSnet, and others. Most international research,

development, and educational organizations are connected in

some fashion to the Internet. Characterized by addresses of

the form [email protected]. The Internet itself

cannot be used for commercial purposes.

UUCP A very primitive network with no management, built with

auto-dialers phoning one computer from another. Characterized

by addresses of the form place1!place2!user. The UUCP network

can be used for commercial purposes provided that none of the

sites through which the message is routed objects to that.

USENET Not a network at all, but a layer of software built on top of

UUCP and Internet.

BITNET An IBM-based network linking primarily educational sites.

Digital users can send to BITNET as if it were part of

Internet, but BITNET users need special instructions for

reversing the process. BITNET cannot be used for commercial

purposes.

Fidonet A network of personal computers. I am unsure of the status of

using Fidonet for commercial purposes, nor am I sure of its

efficacy.

DOMAINS AND DOMAIN ADDRESSING

There is a particular network called "the Internet;" it is somewhat related to

what used to be "the ARPAnet." The Internet style of addressing is flexible

enough that people use it for addressing other networks as well, with the

result that it is quite difficult to look at an address and tell just what

network it is likely to traverse. But the phrase "Internet address" does not

mean "mail address of some computer on the Internet" but rather "mail address

in the style used by the Internet." Terminology is even further confused

because the word "address" means one thing to people who build networks and

something entirely different to people who use them. In this file an "address"

is something like "[email protected]" and not "192.1.24.177" (which is what

network engineers would call an "internet address").

The Internet naming scheme uses hierarchical domains, which despite their title

are just a bookkeeping trick. It doesn't really matter whether you say

NODE::USER or [email protected], but what happens when you connect two companies'

networks together and they both have a node ANCHOR?? You must, somehow,

specify which ANCHOR you mean. You could say ANCHOR.DEC::USER or

DEC.ANCHOR::USER or [email protected] or [email protected]. The Internet

convention is to say [email protected], with the owner (DEC) after the name

(ANCHOR).

But there could be several different organizations named DEC. You could have

Digital Equipment Corporation or Down East College or Disabled Education

Committee. The technique that the Internet scheme uses to resolve conflicts

like this is to have hierarchical domains. A normal domain isn't DEC or

STANFORD, but DEC.COM (commercial) and STANFORD.EDU (educational). These

domains can be further divided into ZK3.DEC.COM or CS.STANFORD.EDU. This

doesn't resolve conflicts completely, though: both Central Michigan University

and Carnegie-Mellon University could claim to be CMU.EDU. The rule is that the

owner of the EDU domain gets to decide, just as the owner of the CMU.EDU gets

to decide whether the Electrical Engineering department or the Elementary

Education department gets subdomain EE.CMU.EDU.

The domain scheme, while not perfect, is completely extensible. If you have

two addresses that can potentially conflict, you can suffix some domain to the

end of them, thereby making, say, decwrl.UUCP be somehow different from

DECWRL.ENET.

DECWRL's entire mail system is organized according to Internet domains, and in

fact we handle all mail internally as if it were Internet mail. Incoming mail

is converted into Internet mail, and then routed to the appropriate domain; if

that domain requires some conversion, then the mail is converted to the

requirements of the outbound domain as it passes through the gateway. For

example, they put Easynet mail into the domain ENE STATE DENSITY ACCESS NUMBER NTWK

On a side note, the recent book The Cuckoo's Egg provides some interesting

information (in the form of a story, however) on a Tymnet hacker. Remember

that he was into BIG things, and hence he was cracked down upon. If you keep a

low profile, networks should provide a good access method.

If you can find a system that is connected to the Internet that you can get on

from Tymnet, you are doing well.

_______________________________________________________________________________

[email protected]<node #>.n<net #>.z<zone #>.ifna.org

In other words, if I wanted to mail to Silicon Swindler at 1:135/5, the address

would be Sil[email protected] and, provided that your mailer

knows the .ifna.org domain, it should get through alright. Apparently, as of

the writing of this article, they have implemented a new gateway name called

fidonet.org which should work in place of ifna.org in all routings. If your

mailer does not know either of these domains, use the above routing but replace

the first "@" with a "%" and then afterwards, use either of the following

mailers after the "@": CS.ORST.EDU or K9.CS.ORST.EDU (i.e. username%f<node

#>.n<net #>.z<zone #>[email protected] [or replace CS.ORST.EDU with

K9.CS.ORST.EDU]).

The following is a list compiled by Bill Fenner ([email protected]) that was

posted on INFONETS DIGEST which lists a number of FIDONET gateways:

Net Node Node Name

~~~ ~~~~ ~~~~~~~~~

104 56 milehi.ifna.org

105 55 casper.ifna.org

107 320 rubbs.ifna.org

109 661 blkcat.ifna.org

125 406 fidogate.ifna.org

128 19 hipshk.ifna.org

129 65 insight.ifna.org

143 N/A fidogate.ifna.org

152 200 castle.ifna.org

161 N/A fidogate.ifna.org

369 17 megasys.ifna.org

NOTE: The UUCP equivalent node name is the first part of the node name. In

other words, the UUCP node milehi is listed as milehi.ifna.org but can

be mailed directly over the UUCP network.

Another way to mail to FIDONET, specifically for Internet people, is in this

format:

ihnp4!necntc!ncoast!ohiont!<net #>!<node #>[email protected]

And for those UUCP mailing people out there, just use the path described and

ignore the @husc5.harvard.edu portion. There is a FIDONET NODELIST available on

most any FIDONET bulletin board, but it is quite large.

ONTYME

~~~~~~

Previously known as Tymnet, OnTyme is the McDonnell Douglas revision. After

they bought out Tymnet, they renamed the company and opened an experimental

Internet gateway at ONTYME.TYMNET.COM but this is supposedly only good for

certain corporate addresses within McDonnell Douglas and Tymnet, not their

customers. The userid format is xx.yyy or xx.y/yy where xx is a net name and

yyy (or y/yy) is a true username. If you cannot directly nail this, try:

xx.yyy%ONTYME.TYM
