This is one of those not so technical tip but certainly the one we need when it comes to talk to Sun Support or creating a documentation. yes, its taking screenshots in Sun Solaris Operating Environment using CDE. Sun Solaris X utilities uses “xwd“, an application that is standard among the X utilities can be used to take screenshots.
xwd dumps the output of a window into a file that can be viewed with xwud, or converted with convert (part of ImageMagick package), xv or another tool to a more usable image type, like png.

In multiprocessor environments, Sun Solaris can allow enabling or disabling Processors. This although is not something that we would do all the time but can come handy when troubleshooting hardware issues.
Sun Solaris has the psradm utility which allows enabling or disabling a Processor on the system. The psradm utility changes the operational status of processors. The legal states for the processor are on-line, offline, spare, Faulted, and no-intr. An online processor processes LWPs (lightweight processes) and can be interrupted by I/O devices in the system.

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. This could be immediatly or at a later time.
The at utility reads commands from standard input and groups them together as an at job, to be executed at a later time.

Setting up a Sun Solaris Server to receive its IP address from a DHCP Server is fairly straight forward and is infact just a matter of setting up files on your Solaris Server.

Everytime you reboot your Sun Solaris Server, you may find that one or more of your Network Interfaces may not come online.
If you did a “netstat -r”
sunsolaris# netstat -r
Routing Table: IPv4
Destination Gateway Flags Ref Use Interface

BASE-ADDRESS.MCAST.NET solaris10 U 1 0 hme0
default 192.168.0.1 UG 1 0 hme0
localhost localhost UH 1 61 lo0
You may not find that the network for the Network interface not found in there (192.168.0.0 here) and as you would expect adding the netmask manually fixes the problem.
sunsolaris# ifconfig hme0 255.255.0.0

The Volume Manager (vold) daemon in Sun Solaris will automatically detect and mount a CDROM when inserted on Sun Solaris under /cdrom (if CD is not labelled )or /cdrom/<label> where <label> is the label of the CD
In instances where vold is not running or when there is a need to manually mount the CDROM the following the procedure should help.
