I used MacOS X already in the past on an “old” MacBook and I have an iMac at home, but recently I am using a MacBook Pro for work. This blog is just a wrap up for “things” that I use often, but for some reason I always forget.

Add Static route

Add a static route via de command.

sudo route -n add -net <network> <gateway>
Example: sudo route -n add -net 172.16.0.0/12 172.18.21.254

Import intermediate / root certificate

Export a certificate from a website, so I am able to import the certificate into the MBP certificate store or import the certificate to other appliances, like ClearPass

openssl s_client -connect www.booches.nl:443 -showcerts
