Silicon Graphics Iris Indigo!
I was fortunate to come across one of these and couldn't resist purchasing it. It is an SGI Iris Indigo. CPU is a MIPS R4000 or R4400, at I think 100MHz. RAM appears to be 160MB, though I may have some more memory to put in. The unit came with no hard drive, but I have a 2GB and 6GB drive that will work. I have old 5.25" external SCSI devices, and an internal SCSI CD-ROM, so I believe I have what I need to attach an external CDROM. The graphics board is the massive Elan board, alone the size of an ATX motherboard.
Now, I need suggestions on what to install as an OS. Problem is, Id really like to put that graphics board to use. So unless I can somehow find a driver for Linux or BSD, it seems as though my only option may be to find a copy of Irix.
Thoughts? Please include any OS, not just Linux. I am very familiar with Debian. Net-BSD seems to be relatively compatible with this machine. Gentoo would work but Ive never tried it. Irix is unfortunately not ideal in that it is not free or open source, but if that's what it will take to take advantage of the graphics board, that will probably be the option I pursue.
Actually, I was also curious about finding a copy of Irix, and maybe just somehow finding the driver for the graphics board and using that in a BSD or Linux install.
Thanks for any suggestions
Cracked the root password on my Indigo -- here's how
Well, I broke into my Indigo running Irix 6.2. It had been sitting on my desk for a week, and I had just ordered a $30 SCSI drive and a $20 PCI SCSI adapter for my PC, so that I could mount the system drive on my Linux system and try to zero the root password. This pretty much guaranteed that I would figure out a way to get into it without needing the stuff I'd just purchased.
If you have an SGI system and don't know the root password, try the following steps:
1. I found a listing of an SGI /etc/passwd file online
2. I noticed that there was a "demo" user with no PW
3. tried it, got logged in
4. was able to list /etc/passwd
5. transcribed the line for "root" into a text file on my Linux system
6. used "john", a password cracker that comes with Ubuntu on it
7. 5 minutes later, john produces:
8. logged in as root, using the "smaat1" as the password.
9. the above took about 15 minutes.
So, if you have acquired an old SGI machine and are missing the root password, apparently the "demo" user is a bigtime security hole! Either that, or it's your ticket to a usable system without having to jump through a bunch of hoops involving mounting the system drive on a Linux system, finding an install CD, unsoldering the PROM, etc.
Obviously, your mileage may vary considerably, depending on how good a password your original system manager chose (and whether he was smart enough to delete the "demo" user Irix installed by default or turn on shadow passwords). And hopefully, the above posting doesn't contravene the rule about no discussion of cracking and warez -- it should fall under "elementary security for classic UNIX systems"!
