Check Now, and Daily updates downloaded automatically sounds good to me. Ah, under System there is a Software Updates icon. The row of icons on the bottom (supposedly called the Dock) seems like a good starting place, specifically one labeled System Preferences. The first thing I want to do is tweak settings and look for updates, standard practice on a Windows machine. Connection to my wireless network is straight-forward. The wizard is simple enough, and I start in Mac OS X.
Interesting that it has the same start sound as the Apple iie. So what's the first thing I do? Boot it up, of course. It's also half the height of my other laptop (Dell Latitude). I won't lie one of the key deciding factors on why I went with Mac was because of the sexy, unibody casing. It exudes sophistication and elegance, right from the moment you open up the box. Initial thoughts: no one does packaging and presentation better than Apple. Neither here nor there, but I also got a free iPod Touch with it (will be writing about separately since it was my first support call)! Woot! Plain passwords on the command line are a security risk.I am now the proud owner of a MacBook Pro (Intel Core i7 2.66GHz), bought on May 17, 2010. $ ssh "echo | sudo -S tcpdump -U -s0 not port 22" -i eth0 -w - | sudo wireshark -k -i. You can check and find the proper one via $ ip link. It depends on its type and count off different interfaces.
And the network interface (eth0) in not necessarily eth0. Port is automatically chosen by protocol specification, so not necessarily required. Replace content in angle brackets to your needs.
This enables root privileges for tcpdump on the host to be sniffed remotely. If you have no root access via ssh on your host being sniffed to, like on a raspberrypi, and for good reason you don't want to enable it or you simply can't do it, for whatever reason, there is a slightly different approach of (alternative to answer to that from we do here is to pipe the sudo password into the sudo command which executes its argument tcpdump.
