Hello All, I have a question in regards to iptables in general, I have been getting these log messages for a while now, and I am trying to figure out why these are coming in, I know that I am dropping all packets from the net 2 dmz named service. My question is why would I get these all the time, they are from multiple different sites. Are they trying to do something to my host or is this a

The following example involves a function whose on.exit() expression both generates an error and catches the error. The body of the function also generates an error. When calling the function wrapped in a tryCatch, should that tryCatch's error function be given the error from the body of the function, since the one from the on.exit has already been dealt with? Currently the outer tryCatch

Hi, I search a way to replace multiple occurrences of a string with different strings depending on the place where it occurs. I tried the following; x <- c("xx y e d xx e t f xx e f xx") x <- gsub("xx", c("x1", "x2", "x3", "x4"), x) what I want to get is; x = x1 y y e d x2 e t f x3 e f x4 but what I get is; x = x1 y y e

Hi, dear R-helpers, I have a simple question regarding selecting subset of a variable based on another variable. Here is the example: xx=rnorm(10) id=sample(1:10, 10) temp=c(6, 1, 8, 2) Now, all I want is xx's that their id are 6, 1, 8, 2, instead of the position. Any suggestions ? Thank you all your help !!

Hi all, I have a bridging firewall running fine with kernel 2.4.31 (Slackware 10.1) and iptables 1.2.11 Yesterday I install the new kernel 2.6.14.3 and iptables 1.3.4 but the bridging firewall doesn't work anymore. Do I need to patch the kernel 2.6 as what I did it for kernel 2.4? Or what I have missed? Regards, ro0ot

I migrated over the usernames/passwords and MACHINE.SID file (is this even used anymore?) and setup smb.conf

Hi, I am trying to plot multiple lines on a graph. The function is particularly simple: sigma<-function(lambda) atm-2*rr*(lambda-0.5)+16*str*(lambda-0.5)^2 which uses the variables atm, rr and str... I define these as such: atm<-0.4 rr<-0.2 str<-0.1 and this plots fine: plot(seq(0.01,0.99,0.01),sigma(seq(0.01,0.99,0.01)),ylim=c(0,1)) Now, I want to plot the same function for
