Building a new box? Time to go find the latest version of Chrome, Firefox, Thunderbird, Skype, etc etc.
One step installer for the most common things you’ll need to install.
This one came from Tekzilla…
Want a list of files in a directory in your clipboard so you can paste it elsewhere? Open up a CMD window, CD to where you need to be. And then…
DIR | CLIP
Then paste it where you need it.
Only seems to work with Vista or Windows 7.

Seems that every time I try to do a reconfiguration reboot of a
new Sparc Solaris 10 Update 6 box, I end up having to take a trip
to the console.
Update 6 includes the concept of a boot_archive, and for some
reason it’s not getting properly updated as the box goes down.
The fix is to get on the console and… (Output below)
But if you’re not near the physical box, and your console isn’t
readily available on the network, you may be in trouble.
Something to consider before starting the reboot…

How many times have we been asked to troubleshoot a server connectivity problem?
Sooner or later, you end up in a three way call between yourself, the firewall folks,
and the admin of the server on the other end, so that everyone can snoop/filter or
otherwise capture an attempted connection. Unfortunately, getting that three way
call going can be difficult, especially when the folks required are not readily available.
Wouldn’t it be nice, if you could just set something up to try the connection over and
over, so that you don’t have to type “telnet {ip} {port}” yourself a million times ?
That’s where netcat (a.k.a nc) comes into play… Available pre-compiled from
Sunfreeware – this little tool will save you some time. The following shell script will
call on netcat to try the connection once a minute until it is successful.
Then it will send an email, and be done.
#!/bin/ksh HOST=1.2.3.4; PORT=567 NOTIFY=someone@somewhere.com WAIT_TIME=5; SLEEP_TIME=55 DONE=1 while [ ${DONE} -gt 0 ] do /local/bin/nc -z -w ${WAIT_TIME} ${HOST} ${PORT} DONE=$? [ ${DONE} -gt 0 ] && sleep ${SLEEP_TIME} done mailx -s "Connection to Host ${HOST} Port ${PORT} succeeded." ${NOTIFY} < /dev/null
You could easily extend the functionality of this… Let’s say you have to maintenance
window where you shut down your application for a while because the database it talks
to in the back end is unavailable… This script could easily “listen” for that database
to be available again, and instead of sending you an email at the end, it could be triggered
to start up your application.
Give it a try.
On a number of occasions, I have had zones just disappear for no good reason.
Until I get to the bottom of that, here is a small script that I have cron’ed that
notifies me that there is trouble.
