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!!!!

A quick guide to At jobs in Sun Solaris
A quick reference guide for “at” utility in Sun Solaris. “at” utility in unix is similar to the “cron” daemon except for that “at” jobs are run only once while cron jobs are recurring. “at” is primarily used to schedule a job which can be command or a script to run once at a particular time although it can be made to reschedule the job.
