Another idea (just reducing it to another form):

Let $$I=6\int \frac{1}{x^2+6x+3} dx=6\int \frac{1}{(x+3)^2-6} dx=\int \frac{1}{(\frac{1}{\sqrt{6}}(x+3))^2-1} dx$$.

Now let $$\frac{1}{\sqrt{6}}(x+3)=\cosh a$$, hence using $$\cosh^2 a - 1 = \sinh ^2 a$$ and $$\frac{1}{\sqrt{6}} = \sinh a \frac{da}{dx}\Leftrightarrow dx = da \sinh a \sqrt{6}$$ we get $$I=\int \frac{1}{\sinh ^2 a} da \sinh a\sqrt{6} = \sqrt{6} \int \frac{1}{\sinh a} da$$.

EDIT: Can someone please show me how to write bigger LaTeX?
EDIT2: Neat!

Integrate a division of polynomials
I need to run an NTP client on a very limited embedded device.  

ntpd is available but I do not see anything like rc.conf, or ntp.conf, or xntp.conf?  Can someone advise on how to setup NTP?  

I ran ntpd, but the date and time haven't updated.
