My son has picked up a Sun Sparc workstation which has Debian 3.1 on it. It was from a freecycle mail list but the preson donating it was a bit clueless - he said he worked for an Apple Store but the iMac he was also trying to make work, didn't. That was due to a blank boot CD and a dead hard drive. The Sun works and gets to a login prompt but that's the problem, no userids or passwords as you might expect. As my son doesn't have broadband and so can't easily download a full CD, is there an easy way to recover the machine, perhaps by blowing away a file containing the afore-mentioned userids? If so, what can I do to help him?
