SSH scans vs connection ratelimiting
Gang,
For months now, we're all seeing repeated bruteforce attempts on SSH.
I've configured my pf install to ratelimit TCP connections to port 22
and to automatically add IP-addresses that connect too fast to a table
that's filtered:
table <lamers> { }
block quick from <lamers> to any
pass in quick on $ext_if inet proto tcp from any to ($ext_if) port 22

Bubble plot pie chart map
Hello,
I am currently trying to show the abundance of two species of
zooplankton within the North Sea as pie chart bubble plots. I followed
Werner Wernersen's advice in R help
(http://finzi.psych.upenn.edu/R/Rhelp02a/archive/48644.html) and used
Paul Murrell's paper "Integrating Grid Graphics Output with Base

New York Times Article: Data Analysts Captivated by R's Power
Readers of this list might be interested in the following article in the

familiar with R describe it as a supercharged version of Microsoft's

Rails on Apache
Hi all,
I''m trying to get rails to run under apache and have looked at the
various how-to pages, but don''t seem to see an answer to my basic question:
Can I do this without using mod-rewrite? Do I have to use .htaccess with
various rewrite rules, or can I just do it with a really minimal
.htaccess that only says something about the AddHandler for .cgi?

finding contours in a matrix
Hi,
I have matrix of sea bottom depths that I am plotting in R with the function
'image'.
I am particularly interested in the 200m depth contour (I'm using 'distance
from this feature' as a covariate in a model) and would like to extract the
data at evenly
spaced points along it. I can easily superimpose a line at 200m using the
function 'contour'. What I

DFS queries via rpcclient to Windows 2012 Server fails
Hello,
We previously had Win2008 R2 DCs which we have begun to replace with Win2012 servers (forest is still at 2008 level however). I was able to query DFS via rpcclient but now I find that I am unable to.
I know that SMB3 was introduced in Win2012 but I believe that it should auto-negotiate earlier versions. I did however test from v4.1.9 as well, unfortunately that still fails.

Searching for specific values in a matrix
Hello all,
I have a seemingly simple question which I have searched for an answer for
for a few hours without luck. I have a matrix of both values and characters
with thousands of rows. I would like to run a search of this matrix for
certain values and would like the search to retrieve the entire row. How
would I accomplish this?
Thanks!

nls confidence intervals
Hi,
Does anyone know how to compute the confidence prediction intervals for
a nonlinear least squares models (nls)?
I was trying to use the function 'predict' as I usually do for other
models fitting (glm, lm, gams...), but it seems that se.fit, and
interval computation is not implemented for the nls...
Cheers

Changing font type within y axis labels
I wish place the following axis label in such a manner that some of the
text is plain and the scientific name is in italics (i.e. a mixture of
two font types)
Using plot:
mtext("Total Landings of Pecten maximus (tonnes)",font,=3, side=2,
line=3)
makes everything italic, but how do I apply the font change to only
"Pecten maximus"?

selectFGR vs weighted coxph for internal validation and calibration curve- competing risks model
Dear Geskus,
I want to develop a prediction model. I followed your paper and analysed thro' weighted coxph approach. I can develop nomogram based on the final model also. But I do not know how to do internal validation of the model and subsequently obtain calibration plot. Is it possible to use Wolbers et al Epid 2009 approach 9 (R code for internal validation and calibration) . It is
