How to find System Serial Number in x86 using ipmitool
As we discussed earlier here, you can find the serial number of a Sun Hardware using the utility “sneep”. However, in Sun X86 systems, you can use the pre-installed tool “ipmitool” to find the system serial number. It is not as straight forward as sneep but still is simpl procedure.
Error Could not get shadow information for NOUSER
Have you ever had the following error popup on your /var/adm/messages:
Oct 8 12:26:14 myserver sshd[29288]: [ID 800047 auth.error] error: Could not get shadow information for NOUSER
It would look like a security incident with the “nouser” system account but not so to be. The error gets written to /var/adm/messages when a user tries to SSH to the server using a user account which doesn’t exist on the system (a typo error can contribute) or on your NIS/NIS+ systems.
So no panic!!!!
