Every once in a great while, I find it necessary to flush my DNS cache. Usually, I only find it necessary to do this after making changes to DNS when at the office, but when attempting to diagnose some interesting Internet connectivity issues, it can occasionally come in quite handy.
I couldn't find anything obvious, but, after a moment's googling, I came across this little gem.
Anyway, here's the command:
First, go here: http://sourceforge.net/project/showfiles.php?group_id=160317&package_id=235898. Get Dynagen_0.11.0-Tig.dmg and, if you don't feel you need Dynagen (you don't), feel free to yank the DynaMIPS executable out of the DMG and throw it someplace useful, just as before.
Next, go here: http://www.gns3.net/download. Get the GNS3 DMG and promptly install the hell out of it.
Now, run GNS3, tell it where to find the DynaMIPS executable, download and configure an IOS image, and voila! You have yourself a shiny new DynaMIPS/GNS3 install in OS X.
Handy? Absolutely. Handier, still, on my MacBook? Oh, hell yes.
Now, it's quiet as can be: no more propping one corner up with a guitar pick or shuffling papers on my desk, a la Jenga. It truly is a beautiful thing.
Ssshh... Can you hear that?
...I didn't think so.
