October 1987 228 ACSS Network Mail

) Paul W. Fakler BITNET: PWF@UMNACVX, PWF@UMNACCA Internet: [email protected], [email protected]

The electronic mail systems on ACSS systems, especially those on the CA and VX machines, have been upgraded over the summer. This article briefly describes those changes and how to transmit and receive network mail on each of the ACSS mainframes after the upgrades. Table 1, on page 232 of this Newsletter, displays the network mail address formats for the CYBER CA, the ENCORE UX, and the VAX VX.

Changes on CA

On CA, the ACSS mail utility (MAIL Version 3.0) has been modified by Mike Pritchard. You can now send and receive BITNET messages within CYBER MAIL-you no longer need to use the BITSEND, NJROUTE, or QGET commands to use BITNET. See Mike Pritchard's article on page 231.

Changes on the VX

On VX, the various network mail software packages have been integrated with VMS Mail, because of the installation of PMDF (Pascal Memo Distribution Facility}, a general purpose system for delivering computer-based mail.

On VX, we installed a mail gateway between UMN.EDU (the Campus Internet) and BITNET. VMS Mail now allows you to send all network MAIL from within VMS Mail-you no longer need to use GMAIL to send to networks other than BITNET.

Network Mail: What You Have to Know

You need the following information to send and receive network mail on ACSS machines:

• A node or host is any machine that you can communicate with using network mail.

• A user is the name by which a person receives mail on a node. It can be your login name (as on UX or VX), or it can be your mail name (as on CA).

• A gateway is a node that forwards mail between two or more networks.

Network Mail on CA

CA (the CYBER 855) is BITNET node UMNACCA. You can send BITNET mail from inside CYBER MAIL. WRITEUP,MAIL, an on-line document on CA, will give you information on how to use MAIL.

continued on page 230

October 1987 229 continued from page 229

You must join the CYBER MAIL utility (with MAIL's join command) to receive BITNET mail. I suggest that you join with an easy-to-remember mail name (for example: first initial, middle initial, and the first 6 letters of your last name). If you join with a name longer than 8 characters, you will not be able to receive BITNET mail. After you have joined MAIL, I suggest that you use your CAuser name (if unique) as your mail alias. That way you will also receive BITNET mail addressed to your user name.

Users on networks other than BITNET can send and receive mail using BITNET gateways. The on­ line document WRITEUP,BGATES contains a list of all"domains" you can reach via BITNET gateways from CA. WRITEUP,BNODES contains a current list of all BITNET nodes.

Forwarding: If you have accounts on several ACSS systems, you may wish to have all of your mail forwarded to one user name on a single system. To forward your mail to UX, type the following in response to a prompt from CYBER MAIL:

Mail? SETFORWARD Enter address or codename to forward messages to? [email protected]

Replace user with your user name on UX.

The CYBER MAIL command status will show your present forwarding address (plus a lot of other information) if you've set one.

To forward your mail to VX, type the following after a prompt from CYBER MAIL:

Mail? SETFORWARD Enter address or codename to forward messages to? user@UMNACVX

See Table 1 (page 232) for address formats for sending network mail from the CYBER CA.

Network Mail on VX

VX (the VAX 8600) is connected to both BITNET and to UMN.EDU, the Campus Internet. Its BITNET name is UMNACVX. Its Internet name is VX.ACSS.UMN.EDU. VX also functions as a gateway for these networks, forwarding messages back and forth between them. See the on-line VX Writeup MAIL for more information on this utility.

If there are people sending mail to you using the old Internet name (UMN-ACSS-VX.ARPA) or any of the local aliases, then they must use the new Internet name. Eventually the old names will fade away, and your friend may have a hard time finding your new address. The way we recommend sending network mail from inside of VMS Mail is to use the IN%" .•• " notation. This calls up the PMDF server to deliver your mail.

The on-line document NET$DOCS:BITNET.LINKS contains a list of all BITNET nodes. A list of all official BITNET gateways to other domains is on NET$DOCS:BITNET.GATES.

October 1987 230 To forward your mail from the VX to UX, type the following lines from within VMS Mail:

MAIL> SET FORWARD "IN%""[email protected]""" MAIL> SHOW FORWARD

Your mail will be forwarded to: IN%"[email protected]. UMN .EDO". Replace user with your user name on the VX. Note the multiple quotation marks!

To forward your mail to CA, type:

MAIL> SET FORWARD "IN%""user@OMNACCA"'"'

Note: If you try to send mail and receive an error message:

PMDF-F-FCRT, File create error

you have run out of disk space, and PMDF cannot create a temporary mail file to send you. Delete some of your unnecessary files and try again.

See Table 1 (p. 232) for address formats for sending network mail from the VAX VX.

Network Mail on the UX

UX (an ENCORE Multimax running the UMAX operating system, a version of UNIX) is also connected to UMN.EDU, the Campus Internet. The full Internet node name for UX is UX.ACSS.UMN.EDU. If there are people sending mail to you via the old Internet name (UMN-ACSS-UX.ARPA) or any of the local aliases, then they must use the new Internet name.

To forward your mail on UX, you must create a file called .forward on your UX login directory. The file must contain only the address where you want your mail forwarded. For example, your file would contain user@UMNACCA when forwarding to CA, and user@VX. ACSS. UMN. EDO when forwarding to VX. In each case, replace user with your user name on the CA or VX.

See Table 1 (p. 232) for address formats for sending mail from the ENCORE UX.

• All mail to BITNET nodes or sent via BITNET gateways is routed through VX by the mailer program on UX. (UX is not a BITNET node.)

October 1987 232 WISCVM Gateway Departs December 1

Linda S. Gray Internet Mail: [email protected] lsg@vx .acss .u mn. edu BITNET Mail: LSG@UMNACVX

WISCVM, a primary electronic mail gateway, will no longer be available as of December 1, 1987. This system has been the major mail routing node between the two major educational and research networks in this country, BITNET and ARPAnet, typically passing five to ten thousand messages a day between them.

To help compensate for this loss, ACSS has installed a mail gateway on its VX system that will route mail between BITNET hosts and hosts on the campus Internet (those computers using the TCP/IP protocols and attached to one of the campus backbone networks). This gateway is registered as the BITNET gateway to the UMN.EDU domain.

To send mail to BITNET from a host on the campus Internet, the address of your correspon­ dent should be of this format:

user%[email protected]

Replace user with the specific user name of your correspondent on her/his computer, and host with the BITNET code name for your correspondent's computer.

You may need to alter this address slightly, depending on the configuration of the mail software on the computer you're using. Alternatively, system managers can alter their software configurations to recognize shorter addresses and automatically send the messages to the VX system. System managers requiring assistance should contact Linda Gray at 626-1321.

When someone on another campus sends messages from BITNET hosts to the Minnesota Internet, they may face more difficulties. If the system host is running one of the standard BITNET mailer programs (e.g., PMDF, GMAIL, Columbia/Crosswell Mailer, Pony Express), your correspondent can put your address into the following format, which is usually sufficient:

[email protected]

Your correspondent replaces user with your user name on your computer, and host with the full name of your computer as specified in the University host tables, in proper domain format. UMN.EDU is the domain name of our Campus Internet.

There are now many University hosts-mainframes, networked workstations, etc.-on which you can receive mail. If you are unsure as to the name of the system on which you want to receive mail, talk to your system administrator or contact Linda Gray.

If the format above does not work on your correspondent's computer, your correspondent should contact the BITNET information representative or the electronic mail manager at their site. ACSS can supply some help in this area, but we cannot always supply information on all the mailer software packages running on different systems within BITNET or on the Campus Internet. f I October 1987 233 1 I Services ...

Xerox 8700 Printing Defaults Changed

Dave Bianchi BITNET: YZE61 08@UMNACCA

As announced in our last issue, on September 20 we changed some of the defaults on the Xerox 8700 laser printer at our Lauderdale facility.

All output printed on the 8700 is now printed in duplex mode (that is, it is printed on both sides of the page) on three-hole punched paper. The text is shifted one-quarter of an inch on the page to allow for the three-hole punch. As before, text is printed in "landscape" mode (across a horizontal page) instead of in "portrait" mode (on a vertical page, like this newsletter).

This new default will make output less cumbersome, because duplex printing reduces by half the number of pages a print job requires. The change also reduces the time required to get your output to you.

Printing In Other Formats

If you are sending a file to the 8700 and want to override these format defaults, you can do it by using the appropriate parameters on the printing command you use.

If you want to print in other formats on the CYBER CA, you need to use several parameters of the PRINT command. For example, use the following format of the PRINT command to get simplex output (printing on only one side of the page) without shifting or three-hole punching:

PRINT,£ilename,UJN=BC*100,S,NP,NS

If you want to print in another format on the VAX VX, you need to use several parameters of the PRINT command. For example, use the following format on the VX to get simplex output (printing on only one side of the page) without shifting or three-hole punching:

$ PRINT filename /FORMS=SIMPLEX /NAME=site.bin

Defaults on the Lind Hall laser printer or on the laser printer at the Diehl Hall Learning Re­ source Center have not changed.

For more information about this change, see the previous article in our September Newsletter.

Conventions

Throughout the ACSS Newsletter, and in a growing number of recent ACSS publications, we have adopted these conventions:

• Messages and prompts from the ACSS computers appear in plain type, like this.

• Words that the computer systems replace with a specific name, value, or other information appear in italic type, like this.

• Commands you type at your terminal keyboard appear in bold face type, like this.

• Words that must be replaced by a specific name, value, or command that you type in appear in bold italic tY,Pe, like this.

• Comments to interactive sessions and program files are enclosed in { curly braces, like this }.

Here's an example:

save, filename is a command you type in. You type save and replace filename with the name of your file. The system may respond with the message

filename ALREADY PERMANENT {An example of a system message. } where filename will be replaced by the name of the file you attempted to save.

• The symbol refers to the carriage return (or RETURN) key on the terminal. The serves as a terminator for commands you type at your terminal. In most cases we do not show ; we assume you know to type it after every command .
