Who is the CCO Rep?

James Dooley. His email address is jdooley@ugcs.caltech.edu. His extension is x1604. He lives in room 136. Feel free to bother him anytime, although if you wake him up it had better be important.

How do I get ethernet in my room?

E-mail me: 1) your name, 2) your room number, 3) your e-mail address, and 4) your phone number. I will pass on the request to the appropriate person. Downstairs they will be running twisted pair (10BaseT, looks kinda like a telephone cable). Upstairs will be converted to 10BaseT during Spring Break. Talk to Mike Michrowski for more information about the conversion.

Now that I have ethernet, how do I get an IP address?

Send e-mail to hostmaster@cco including your email address, the name you would like to give your system, and your house, and she will set things up for you.

What workgroup should my Windows/95/NT or SMB-configured Linux system belong to?

RUDDOCK. Wakko is the Master Browser. You should still be able to access Wakko from DISNEYLAND, though.

What AppleTalk zone should my Mac belong to?

NET6. You should only have two options, NET6 and CiscoCCO. Because your computer is not owned by CCO and doesn't reside in Jorg it probably shouldn't go under CiscoCCO...

What is this NET6, NET90, NETxx stuff?

I tend to use these terms interchangably for three different things: physical subnets, logical subnets, and AppleTalk zones. For a number of reasons (mostly performance related), TCP/IP networks break up groups of computers into smaller units called subnets. Each of those numbers corresponds to a logical subnet number. Most people with new computers in Ruddock should have NET90 addresses (131.215.90.xxx), although many of us old-timers still have NET6 addresses (131.215.6.xxx). Physically there is no difference because NET90 is only a "phantom" subnet, so while it is logically different from NET6 it uses the same physical cables as NET6. Because NET6 is totally saturated (there are something like 400 nodes on a physical subnet that is only supposed to support up to 250 nodes) CCO is working on splitting the houses up into their own seperate physical subnets, which is why they don't give out NET6 addresses anymore. When this split happens Ruddock's subnet will be NET90. If you have a NET6 address don't worry about getting your address updated because the split won't be happening anytime soon. CCO also has plans to upgrade to 100BaseT around that time.

What do I need to do to be able to print from my computer to one of the laser printers in the Computer Room?

First of all, you need to be hooked up to ethernet. If you are using a Mac, you just need to use the Chooser; the printers are on NET6. Be sure you connect to "Maleficent" if you are upstairs, or "Ruddock HP" if you are downstairs and not some variation on those names. These altered names (usually containing "_NTQ") are garbage created by NT machines and will be a lot slower and less reliable. If you are using Windows 3x/95/NT, connect to Wakko, which should be in the RUDDOCK and DISNEYLAND groups. If you can't see Wakko, make sure you have a TCP/IP stack installed (You can only run Netscape if you have one installed). If you still can't see Wakko, try typing in the address \\wakko\ruddockhp or \\wakko\maleficent directly. You can reach all CCO printers this way. If you are running Linux, see the printcap files for RuddockHP and Maleficent.

What kind of printers are RuddockHP and Maleficent?

Maleficent is a Compaq Pagemarq 15, with postscript support. This is sometimes referred to as the "v2012.015" version. It has 4MB of memory and feeds Letter out of the upper and lower trays. RuddockHP is a Hewlett Packard LaserJet 4MV (also postscript). If you can't find a 4MV driver, the LaserJet 4V driver will also work. You may also borrow the 4MV driver disks from the CCO-Rep. RuddockHP has 12MB of memory and feeds Letter from its only tray. If you need help with any of this please ask the CCO Rep.

I had a file on one of the drives, and now it isn't there anymore. Is someone deleting my files?

Most likely you saved the file to somewhere other than your user directory or an appropriate save-game directory. In that case your file may or may not still be where you put it, as the CCO Rep goes through periodically and moves all files that aren't where they should be to the "LOST&FND" directory on the appropriate drive. If you can't find your file there, talk to the CCO Rep and hopefully he can help you find it. If a computer runs out of space, I'll typicaly pick a large program/game that I have never seen used and delete it. In general, I won't delete anything in the user subdirectories, though I will ask people taking up large amounts of space on the hard drives to clean their directory(ies) out.

I lost my default TCP/IP settings. What are the general defaults?

If you have a 131.215.6.xxx address your default gateway is 131.215.6.254 and broadcast is 131.215.6.255. If you have a 131.215.90.xxx address your default gateway is 131.215.90.254 and broadcast is 131.215.90.255. Your subnet mask should be 255.255.255.000. For nameservers use 131.215.139.100, 131.215.9.49, and 131.215.145.137. If you can't remember your ip address go to another system and do a nslookup on your system name. Don't worry if you don't use all of these parameters, not all implementations need all of this information.

Microsoft's TCP/IP setup complains that I don't have a Primary WINS Server configured. What can I do to shut it up?

Wakko is set up as a WINS server. The ip address is 131.215.6.195.

Where did the names in the Computer Room come from?

Most of them are the fault of Dave Cuthbert, the CCO Rep when they were donated. The Pentium's name was suggested sometime first term, and it was finally named mountain-dew when a new ethernet card was installed in it. The HP printer still needs a name. Email suggestions to me.

Is there a way I can print from my PC without having to go through a server somewhere?

To Maleficent, no, unless you can print over AppleTalk. If you're running Linux, just install the netatalk pacakge to enable AppleTalk. Here's how.
To RuddockHP, AppleTalk is an option as well, but you can also print to it using lpd, which is far easier to use in UNIX-land. See here for a sample printcap entry. You can also print to RuddockHP using DLC, which is supposedly easier to come by for Windows 3x/95/NT users. All you will need to do is install the DLC protocol and give it the printer's node number (0800090C1895).
