Is there a
standard procedure for recovering lost passwords for these systems, or for resetting
passwords? I do have physical access to the machine; it?s possible I can find an AIX
install disk but it?s *highly* desirable to preserve the contents of the existing hard
drive.
Image the hard drive off to a raw file using a linux host with a SCSI HBA?
Once that is done, it might be possible to run a hex editor against the hard drive (one
that doesn't copy the contents into RAM) and then search for the password file. From
there you can copy the des hash and use rainbow tables / wordfiles to crack it or replace
it with a known DES hash?
This is how I used to reset my root password on my Lucent Audix UNIX host.
YMMV, others might have more insight.
Update, I did locate a CD saying ?AIX V4.2.1 for 5765-C34? and this URL:
http://www-01.ibm.com/support/docview.wss?uid=isg3T1000366
which may be what I need. I?ll try this ASAP, hopefully tomorrow, and report what happens.
Thanks, and any more ideas welcome!
