similar to: firewalls, a practical question

A little over a week ago I posted asking about setting up a linux box between an existing router and a switch in order to provide firewall service to a subnet of machines. I was curious what experience others had with this type of setup in terms of machines, configurations, and the appropriateness of using linux in this manner. There were basically three issues discussed in replies: hardware

Hi Are there any known security holes or necessary precautions in using port forwarding with ipportfw? I'm planning on forwarding ports from an outer firewall/router (connected to the Internet) to a host in the DMZ, then on from the DMZ host to the inner firewall, and finally from the inner firewall to some host on the inside.

R-users, Has anyone implemented (coded) the Rai and Van Ryzin dose-response model from their 1985 Biometrics paper. I'm trying to avoid re-inventing the wheel. If not any hints on coding this would be greatly appreciated. Thanks, -- ==================== Calvin L. Williams, Ph.D. ==================== Department of Mathematical Sciences, Clemson University

R-Users, I'm in the process of developing some notes on optimizing likelihoods for a class I'm teaching next term. Can anyone offer examples showing the optimization of a complex likelihood function that they wouldn't mind sharing using optim(). I've adapted some of the S-plus likelihood examplesfrom the ``Guide to Statistics" and the Zip example from ``Statistical Models in

Hello: The following code extracts the links to the daily transcripts of Canada's House Of Commons. 'links' is a matrix of URLs (ncol=1), each of which points to one day's transcripts. If you inspect the code for scrape(links[1]), you will find that periodically there appears an italicitze tag after a paragraph tag (<p some text ><i>Translation</i></p>.

R-users, This may be a simple problem, but I don't have an intuition of how simple it could be. Suppose I have a sequence of numbers corresponding to a series of diagnoses on the same patient over a sequence of time. The diagnoses are coded 1,2,3,4,5, but could come in a sequence like 1,3,2,5,3,5,...etc. Is there a simple way to count the number of times a 1 diagnosis is followed by a 2, or a

Hello. I came across your response in an R forum and could use your help. I have a data set with 472 rows. I want to delete rows 416 through 472. The name of my data set is MERGE. I am an extreme R novice. How do I write a script to accomplish this? Thank you. --- Christopher H. Porter, M.A., M.Ed.

I'm new to SAMBA and am somewhat confused. So I'll get right to the point. Situation: I am running both UNIX (Solaris 9) and Windows 2000. I have a system running on Windows will be creating some large files. These files need to be input to a system running on the UNIX (Solaris) box. Solution? I would like to be able to have the system on the UNIX box be able to read the files on Windows

Hello all- I am doing a survival analysis for two species of invasive plants I outplanted to edges and interiors of island and mainland sites in a local reservoir. I am using the KM estimate and had no problem doing survdiff for my data using the following code: S4<-Surv(outplant$SurvTime, outplant$StatusD6) diff4=survdiff(S4 ~ outplant$Species+outplant$SiteType+outplant$EdgInt) diff4

Hello All: I am very new to R and am trying to import some (107) text files into R while simultaneously manipulating the data into a structure that I can use. Below is a description of what I am trying to ultimately accomplish. However, I find that I am unable to even read one file into R using the read.table function. I get the following error: > test<-read.table("test4.txt")

I'm looking for a way to batch create a list of computers accounts in Active directroy running on Windows 2000 PDC. I tried to use perl ldap to create those objects but I didn't manage to set the sAMAccountType to "805306369" ( apparently this is a read only auto generated value) Is there any way to do that under Linux ? Thanks, Thomas #! /usr/bin/perl use strict; use

Hi. I am very new to R and have been diligently working my way through the manual and various tutorials. I am now trying to work with some of my own data and have encountered a problem that I need to fix. I have a dataframe with 8 columns and approximately 850 rows. I have provided an excerpt of the dataframe below. Within column 6 (Question) the numbers 1:33 repeat down the entire column.

I am still fairly new to R and have a fairly rudimentary question. I am trying to name a vector of coefficients retrieved from a multilevel model using the coef function. I guess the default name is "Intercept" and I cannot figure out how to rename it. I have tried the using the code below to name the column of coefficients ind.y derived from an lme model. Unfortunately, the
