Learning something new every day…

One of the things I really like about working within a team in one location is the fact that are able to learn something new regularly. And of course you are also able to give some useful advice to others 🙂

Something I learned this week is how to turn on the UID light on a HP server without logging into the iLO webinterface. You can use the tool hpasmcli – which probably can do some more useful stuff too 🙂

“I solved it” – Java with MacOSX

Many of you have probably noticed during the last months. Java is somewhat broken with MacOSX since Oracle started shipping Java7 for MacOSX. Some of the things I recommend about using Java on MacOSX:

– Install the SDK even if you do not necessary need it as it might fix some problems
– If you upgrade Java7 and you need Java6 for some applications (e.g. in my case it was Cisco ASDM configuration for Cisco ASA), you might need to reinstall Java6 (latest version as of July 2013 is here: https://support.apple.com/kb/dl1572 ). I have no idea what it does, but it does something with the binaries in /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/ – sizes seem to be the same, I don’t have any md5sums…

Hopefully that should fix most of the Java issues.

Hello world! New Homepage!

Today I have started a new homepage. I’ll try to update it somewhat regular with private stuff as well as some thing I am stumbling upon during my work as a sysadmin.
