Easy way to reject all incoming packets except from certain IPs?
Is there an easy way to reject all incoming packets except those that come
from certain IPs? I can't find any way via iptables or via the GUI provided
with CentOS (or another GUI for CentOS) without having to resort to
Shorewall. It's fine if the answer is "go with Shorewall". I just didn't
want to have to become a Shorewall expert for this really small task.
Any help/advice

ssh attack
Hi,
I get ssh connect attempts all the time, to my servers at home and at
work. I've noticed lately they come from a certain ip address, hitting
every 3 or 4 seconds, trying 50 or 100 different user names and
passwords. And I get these sweeps from 2 or 3 ip addresses a day. I
guess this is an automated attempt to guess a user/pass and break into a
system.
I tried to secure ssh better by

I am having a problem understanding the lda package. I have a dataset here:

Find reason for heavy load
My Centos 5 server has seen the average load jumped through the roof
recently despite having no major additional clients placed on it.
Previously, I was looking at an average of less than 0.6 load, I had a
monitoring script that sends an email warning me if the current load stayed
above 0.6 for more than 2 minutes. This script used to trigger perhaps once
an hour during peak periods. Even so, I

help files for libraries that aren't in the defaults library tree
Hello,
I created a library for a bunch of functions that I use frequently

up an R sesssion. However, I have problems locating the help files
for those functions. Here are some details.
I created the library "myR" and installed this in /home/royle/R

[cfe-dev] FE_INEXACT being set for an exact conversion from float to unsigned long long
I think it’s generally true that whenever branches can reliably be predicted branching is faster than a cmov that involves speculative execution, and I would guess that your assessment regarding looping on input values is probably correct.
I believe the code that actually creates most of the transformation you’re interested in here is in SelectionDAGLegalize::ExpandNode() in LegalizeDAG.cpp. The

FENV_ACCESS and floating point LibFunc calls
Thanks, Andy. I'm not sure how to solve that or my case given the DAG's
basic-block limit. Probably CodeGenPrepare or SelectionDAGBuilder...or we
wait until after isel and try to split it up in a machine instruction pass.
I filed my example here:
https://bugs.llvm.org/show_bug.cgi?id=33013
Feel free to comment there and/or open a new bug for the FP_TO_UINT case.

cant restore .Rdata
Hi Folks,
I loaded a couple of quite large data sets into an R session and then
quit (after saving the image). Now I get:
Error: a read error occured
Fatal error: unable to restore saved data
(remove .RData or increase memory)
after trying to start my R session using something like:
R --vsize XXX --nsize 1000000
For any value of XXX (I went up to 300 or 400, which is as high as I could
go.

Multiple logistic regression
Dear R-users,
Is there a function in R that classifies data in more than 2 groups using
logistic regression/classification? I want to compare the c-indices of
earlier research (lrm, binary response variables) with new c-indices
obtained from 'multiple' (more response variables) logistic regression.

[LLVMdev] sprintf -> snprintf conversion
Hello, llvmdev!
I'm using LLVM on OpenBSD. This project proactively advocates usage
of 'secure' C apis, especially related to memory bounds checking.
Thus using functions like sprintf/strcpy/etc usually spits out a
linker warning in base toolchain like this one:

help with "attach"
Hello,
I've been migrating my computing to R and have not had any major
problems running old Splus programs in R. However, the one thing
I am missing is the ability to attach directories full of general
utility functions from whereever I happen to fire up an R session.
As a consequence, I find myself making many duplicate copies of
these little general purpose functions by cutting and
