I'm trying to use nls() to fit an exponential decay with an unknown offset in the time (independent variable). (Perhaps this is inherently very difficult?). > decay.pl <- nls (amp ~ expn(b0,b1,tau,t0,t), data = decay, + start = c(b0=1, b1=7.5, tau=3.5, t0=0.1), trace=T) Error in nlsModel(formula, mf, start) : singular gradient matrix at initial parameter estimates > > expn(1, 7.5, 3.5, 0.1, decay$t) [1] 6.636080 5.259657 4.164661 2.797383 1.760584 1.250300 a...

Hi, In the third edition of the MASS book, Chapter 8, Page 252 ~ 253. I tried applying the same technique on using a negative exponential model (as suggested in Exercise 1), and trying to get a confidence interval. What I have changed is follows: expn <- function(b0, b1, th, x) { temp <- exp(-x/th) model.func <- b0 + b1 * temp # Differentiate temp derive.negexp <- (x * temp) / th^2 Z <- cbind(1, temp, derive.negexp) dimnames(Z) <- list(NULL, c("b0","b1","th")) attr(model...

Dear All, I have two machines, a Centos 3.4 machine and a Centos 4.1 machine. I have used the same sendmail.mc file on each, and 3.4 machine does plain SMTP auth with no problems, compiling the same mc file on the 4.1 machine gives this error: xxxxx [x.x.x.x] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA in the logs, it doesn't even try to authenticate, the cyrus sasl rpm is installed for auth PLAIN It reports this from the EHLO so all looks good: 250-ENHANCEDSTATUSCODES 250-PIPELINING 250-8BITMIME 250-SIZE 250-DSN 250-ETRN 250-AUTH DIGEST-MD5 CRAM-MD5 LOGI...

These hosts sit on different netblocks and on both machines the sendmail.cf files date from Jan 09, 2007. The last successfull connection from any hotmail acocunt was on Jan 15 at 13:17:29. The firs...

...but don't know how to figure out what the IP address is. I don't see anything in the "maillog" that, for example, has the name "bettie" or some other clue. The only thing I see is a message like sendmail[5452]: v9HIoBox005452: [xxx.xxx.xxx.xxx] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA with a close timestamp, but I'm reluctant to tie the two log entries together. Is there some log, or log setting that might enable me to tie the do_auth error to a specific IP address? I'm very reluctant to change mail servers to postfix or something...

hello, i wondered if it would not be interesting to have some filters function in puppet like filter_integer(), filter_prelregex, filter_text, filter_email or such so we can validate and make our defines a little more foolproof :) i particulary see filter_regex as usefull in quite a lot of exec that manipulates text files. What do you think about this ? -- Cordialement, Ghislain

Hi , I have posted DTrace script to snoop tcp traffic and also provided a wrapper script for it to filter out unwanted traffic. http://blogs.sun.com/roller/comments/raviswam/Weblog/tcp_snoop_using_dtrace Please let me know if you have any feedback/comments on this. Thanks Ravi

Someone I was speaking with this evening claimed they have installed the latest named rpms yet they are still getting exploited daily and being hacked. Do the latest rpm''s for the named 4.9.x stuff fix all the root exploits or is this person just an idiot who probably has holes elsewhere in the system?
