similar to: Proposed RST patch

Hello security gurus, yesterday, I mistakenly posted a question on the questions list about this article : http://www.securityfocus.com/bid/13676/info/ which talks about a form of DOS vulnerability. I was curious as to the possibility of FreeBSD 5.x being affected, and if anyone was working on this or not. Ted Mittelstaedt posted this possible patch based upon the OpenBSD patch : in

yes unless you use the version as of :> 2004-03-02 17:24:46 UTC (RELENG_5_2, 5.2.1-RELEASE-p1) check it out with uname -a if it does not say -p1 it affects you. My guess, you are affected :) cheers -- Kind regards, Remko Lodder Elvandar.org/DSINet.org www.mostly-harmless.nl Dutch community for helping newcomers on the hackerscene -----Oorspronkelijk bericht----- Van:

I can't test that at the moment as I don't have the libraries. Perhaps later.

Last line in the following (updated) code produces the error require(raster) require(rts) require(stringr) r <- raster(ncol=100, nrow=100) values(r) <- runif(ncell(r)) stack(r)->s r->rs for(i in 1:23){ rs[]<-r[]*i addLayer(s,rs)->s print(nlayers(s)) } dt<-list(ID=seq(1:24),month=rep(formatC(1:12,flag=0,width=2),2), year=sort(rep(2016:2017,12)))

It works if you use as.Date. But this defeates the purpose for the yearmon notion... require(raster) require(rts) require(stringr) r <- raster(ncol=100, nrow=100) values(r) <- runif(ncell(r)) stack(r)->s r->rs for(i in 1:23){ rs[]<-r[]*i addLayer(s,rs)->s print(nlayers(s)) } dt<-list(ID=seq(1:24),month=rep(formatC(1:12,flag=0,width=2),2), year=sort(rep(2016:2017,12)))

Which function was being evaluated to produce the error? I don't see

Hi Herry, This is probably due to a call to strptime (or similar). No, it doesn't accept %Y-%m as a valid format. Maybe add a constant day to all the dates as that will work: dt<-list(ID=seq(1:24),month=rep(formatC(1:12,flag=0,width=2),2), year=sort(rep(2016:2017,12))) timelst<-paste(unlist(dt['year']),unlist(dt['month']),"01",sep="-")

Hi List, The following code returns an "Error in as.POSIXlt.character(x, tz, ...) : character string is not in a standard unambiguous format" require(raster) require(rts) require(stringi) r <- raster(ncol=100, nrow=100) values(r) <- runif(ncell(r)) list(ID=seq(1:24),month=rep(str_pad(1:12, pad = 0,width = 2 , "left"),2),year=sort(rep(2016:2017,12)))->dt

Box with fresh RELENG_7 panic under heavy network load (more than 50k connections). This panics seems to be senfile(2) related, because when sendfile disabled in nginx, I can't reproduce the problem.

Hi, I've encountered a strange problem while using FreeBSD 6.0 for our local mirror (mirror.math.uni-bielefeld.de) and thus is providing access via ftp, http, rsync and cvsup (all local and remote). The system crashes periodically with a kernel panic (panic: sbdrop). The uptimes between two crashes are going from a few hours to a few weeks. The system is a i386, Intel Pentium 4 based with

I''m running 2.6.7 + (julian''s multi-path patch) + IMQ (imq2+beta6) and I got the following on my console while doing some stress testing: KERNEL: assertion (tp->retrans_out == 0) failed at net/ipv4/tcp_input.c (1827) I don''t know what I would do to try to reproduce this condition; it only appeared once. tcp_input.c sounds deep enough to scare me off from looking

Hello I'm a bit confused about the "tcp time stamp validation bug" mentioned in the http://www.kb.cert.org/vuls/id/637934 advisory. FreeBSD has fixed this issue in -current (2005-04-10) and in RELENG_5 (2005-04-19). Is this also already fixed in 5.4? The CVS ID for tcp_input.c does not look like this. But I'm not sure. Regards, Thomas
