Darkavich's Daily Ramblings

So at the ball game today I decided to see how good the iPhone app is that recognized songs and allows you to purchase them. Between each inning they play music and I have wonder what some of the songs are. So, I started up Shazam! and well… Shazam! it recognized every song!

This app rocks!

I received my two yubikey’s today. I quickly found the wordpress plugin and it JUST works after adding the plugin and setting up my account. Now I want to see if I can use this for my unix login and all other forms of authentication.

Digging through my old email archives I found this:

Ok, I learned something really cool today from Sun.
How can you tell if a process is chroot’d or not? ps gives you no clue, nor does the kmem.
Here is a neat trick to figure this out.  You have to love those kernal hackers!!!

% ps -aef | egrep nscd
root  1022     1  0 09:21:20 ?        0:00 /bb/bin/nscd
% crash -d /dev/mem -n /dev/ksyms
dumpfile = /dev/mem, namelist = /dev/ksyms, outfile = stdout
> p #1022
PROC TABLE SIZE = 30000
SLOT ST  PID  PPID  PGID   SID   UID PRI   NAME        FLAGS
47 s  1022     1  1022  1022     0  50 nscd           load
> user 47
PER PROCESS USER AREA FOR PROCESS 47
PROCESS MISC:
command: nscd, psargs: /bb/bin/nscd
start: Thu Oct 24 09:21:20 2002
mem: 1fd, type: fork
vnode of current directory: 300041d98e8, vnode of root directory: 300041d98e8,
[rest of output deleted]

Run crash, then “p #pid”, then “user SLOT”

The fact that it lists “vnode of root directory” means it is chroot’d.

pretty cool 😉

For those of you wanting to know how to use ARD through a firewall or NAT bridge:

If you wish to use the Remote Desktop application from behind a NAT router, you will need to set UDP port forwarding for port #3283 to your administration computer. If you wish to access a client computer that is behind a NAT router, you will need to set the router to forward UDP port #3283 to the client computer you wish to access. Note: You will be able to access only that client computer.
