We have been noticing flurries of sshd reject messages in which some system out there in the hinterlands hits us with a flood of ssh login attempts. An example: Apr 6 05:41:51 dc sshd[88763]: Did not receive identification string from 67.19.58.170 Apr 6 05:49:42 dc sshd[12389]: input_userauth_request: illegal user anonymous Apr 6 05:49:42 dc sshd[12389]: Failed password for illegal user

I recently discovered that I need to occasionally forward Email from a FreeBSD system to a Macintosh. Imap does look like the best solution to this problem. The mail program on the Mac lists several protocols such as pop (okay with me) and SSL certificates which I want to avoid if at all possible. Which of the several listed methods of authentication should I compile in as I build dovecot on the

I've spent the morning looking at making some RPMs for Fedora Core 1 and run into a problem with GSSAPI. Basically the default install of Fedora doesn't come with the necessary gssapi code to build the RPMs by default (i.e. you need to say %define kerberos5 0 in openssh.spec). Since Fedora is going to fork off from RedHat I was going to create a set of patches to make a

Hi, Does anyone know how to do a coord_trans() in which the y-axis is tranformed into (for example) -1000/y?

Hi, I would like to use the effect() function (actually a slightly modified version of it) on the output of the lmer() function in the lme4 package. But the effects package requires the nlme pacvkage, which is incompatible with lme4. Workaround? ______________________________________________ Professor Michael Kubovy University of Virginia Department of Psychology for mail add: for FedEx or

John, The following steps should work for you (or anyone buildling on a RedHat box): 1) Get the official OpenSSH source RPM from ftp://ftp.openbsd.org/pub/OpenBSD/OpenSSH/portable/rpm/SRPMS/openssh-3.7.1p2-1.src.rpm 2) Do 'rpmbuild --rebuild ./openssh-3.7.1p2-1.src.rpm' from where you saved the file. 3) This should create the following files in /usr/src/redhat/RPMS/i386:

How does one define PDFs as yet undefined in R, such as the ex- gaussian, the sum of two RVs, one exponential, one Gaussian? The PDF would then be the convolution of an exponential PDF, dexp(), and a normal, dnorm(). Kindly cc me in your reply to r-help.

df1 <- data.frame(a = LETTERS[1:2], b = LETTERS[3:4], c = 1:2) I am looking for an idiom that swaps the elements of df$a and df$b when (e.g.) df$c == 2, resulting in df2 <- data.frame(a = LETTERS[c(1, 4)], b = LETTERS[c(3, 2)], c = 1:2) _____________________________ Professor Michael Kubovy University of Virginia Department of Psychology USPS: P.O.Box 400400 Charlottesville, VA

Summary: + I am writing an R extension that needs to call dmvnorm more than 10,000 times during a model fitting computation. + My extension uses openmp for parallel execution. + As of R 3.0, it is no longer permitted for threads to call the R interpreter because there is a stack overflow check that always trips because the thread's stack is different from what R is expecting. +

Hi all, While working on a loadable Alias Analysis module pass, I'm running into the following issue: I'm finding my pass queried for results after it has had 'releaseMemory' called on it and its dependencies, but before runOnModule is called again (on my pass or its deps). As you might expect, this makes my pass rather unhappy (and I think correctly so). This happens with LICM

Dear R-helpers, It is not clear to me how you get measurement.error SD when you have a single dataset, and it is not clear to me how sensitive SIMEX is to errors in the estimates of measurement error. Could someone please point me to the relevant literature? _____________________________ Professor Michael Kubovy University of Virginia Department of Psychology USPS: P.O.Box 400400

Dear r-helpers, Can anyone suggest why lm() doesn't complain here: summary(osss.lm1 <- lm(logOdds ~ c.setSize %in% task, data = osss)) whereas in package:nlme (and in package:lme4) osss.lmL <- lmList(logOdds ~ c.setSize %in% task | subj, data = osss) # Error in `contrasts<-`(`*tmp*`, value = "contr.treatment") : # contrasts can be applied only to factors with 2 or more
