We have two SGI/O2 operating pm Irix 6.3. On Nov 30 at exactly the same
time (18:02) they both have the "su" password protection turned off. So
anyone can get to super user mode without a root password. we found out
that a file called .rhost containing two + signs was added under /. After
deleting the file "su" works normal (will ask password) again. This may
affect anyone who has a O2 if the problem is caused by some system bug. We
know another O2 in our campus having the same problem starting at the same
time.
Another problem may be related to the first one: the SYSLOG file is now
constantly adding this line
"bootp [16713]: DHCP request, server not configured. exiting."
Have anyone got this problem also? If you have how have you solved it?
Thanks,
Wei
