eVX Frequently Asked Questions


Q: What was eVX?

A: eVX was an acronym for "eta.infinity / VorteX", the names of the 2 systems involved in the eVX SL/IP Alliance.


Q: What was the eVX SL/IP Alliance?

A: The eVX SL/IP alliance was the name given to a SL/IP (Serial Line / Internet Protocol) connection that linked 2 computers in Appleton, WI over the phone line. The Alliance also entailed an attempt to set up, learn, and configure all the 'major' networking utilites for UNIX, in the preparation that eta.infinity would be connected to the Internet at the University of Wisconsin, Madison, which it did.


Q: Who was involved in this project?

A: Matthew R. Peterson (aka Avrex), System Administrator of eta.infinity and Jonathan W. Day (aka Lucipher), System Administrator of VorteX.


Q: What type of hardware and software was used?

A: 
eta.infinity

Software: Macintosh System 7.1 and 
          MachTen UNIX v2.1 (BSD4.3) from Tenon Systems

Q: How long did eVX last?

A: Aproximently from May, 1994 to July, 1994, when we both moved from Appleton, WI to Madison, WI to start college.


Q: Did you have everything scripted, and set up so if it disconnected, it would automatically call back?

A: Yeah, whatever!

Lucipher had an account on America OnLine (AOL) which he used fairly often, so he would take down the SL/IP connection without warning to dial up AOL. I would only find out later that I had to re-establish the connection by having him call me, or if I tried to telnet to his system and nothing happened.


Q: So what excatly did you have to do to connect to VorteX from eta.infinity?

A: We pretty much didn't bother with too many scripts, especially the ones provided with BSDI, so the following is the process Avrex went through each time to connect:

eta% call
[Which was the following script:
 #!/bin/sh
 stty 57600
 tip -57600 tty00
]
atdt7313383
CONNECT 57600
4.3 BSD (VorteX.eVX) (tty00)

login: etaslip
Password: 

[bunch of misc stuff from /etc/motd woudl appear]
Starting SL/IP Script
[then I would suspend the telnet session and kill it]
eta% slipon
[Which was the following script:
 #!/bin/sh
 stty -f /dev/tty00 cts_oflow rts_iflow
 slattach /dev/tty00 57600 
 ifconfig sl0 89.0.0.2 89.0.0.1 link2 up
 echo "eVX SL/IP Integrity Established"
 echo "89.0.0.2 (eta.infinity.eVX) <----> 89.0.0.1 (VorteX.eVX)"
]
eta% ping VorteX.eVX
[Just to make sure the system was connected]

And that was it... fun. Not.
Q: Why didn't you set eta.infinity up to be the 'dial in' so Lucipher could call AOL, and then call eta.infinity when he was done?

A: BSDI BSD/386 is not a pretty Operating System at times... enough said.


Q: What was the longest time you had the eVX SL/IP running continously without a broken connection?

A: I'm trying to remember the longest I saw on 'uptime', but I think it was around 17 days. Of course our systems were on 24 hours a day from May to July.


Q: Any problems with the Alliance?

A: The BSDI Sendmail didn't seem to like anyone, it worked for a while, but then just died. Though when eta.infinity was attached to the Internet via Ethernet, Sendmail worked perfectly, and still does.

NFS (Network File System) didn't seem to work well with MachTen and the Macintosh file system, especially when trying to view a .GIF through XV on the Macs Hard Drive, at 9600 baud. It crashed the Macintosh. Needless to say, NFS / nfsd was disabled.

nn (news), we never did get it compiled, it wasn't SL/IPs fault though. Doesn't matter, now eta.infinity has "tin".


Q: Did either Matt or Jon loose any sleep during the eVX SL/IP Alliance?

A: I think The SL/IP Storybook will answer that question...


Q: Last question, why did Matt Peterson write "The SL/IP Storybook"?

A: It was written in response to the "SL/IP Cookbook" article that appeared in AXCESS Magazine, and submitted to them in an attempt to show them that SL/IP can be hell. There was never an acknoledgement that the story was recieved, and was never published.
