raster time series statistics
...pad = 0,width = 2 , "left"),2),year=sort(rep(2016:2017,12)))->dt stack(r)->s r->rs for(i in 1:23){ rs[]<-r[]*i addLayer(s,rs)->s print(nlayers(s)) } timelst<-paste0(unlist(dt['year']),'-',unlist(dt['month'])) rts(s,time=as.yearmon(timelst))->rsts str(rsts at time) apply.monthly(rsts,mean) I was expecting that the statistics accept the yearmonth format of the timeslot, as it allows subsetting. Any suggestions? Thanks Herry [[alternative HTML version deleted]]

Proposed RST patch
...cking, but connections in other states are only subject to the "within the window" check. Part 2 of the patch is simply a patch to netstat so that it displays the statistic. As expected, it's very straightforward, the only real question is what to call the statistic... "Ignored RSTs in the window" isn't the best description. FWIW, I've been testing with the exploit code (reset-tcp-rfc31337-compliant.c from osvdb-4030-exploit.zip), and this change does indeed defeat the attack. It took me a while to get the code working, they really munged up the libnet calls, bu...

[Bug 118] NAT stops working
...on comes from the workstation, and is greeted with a SYNACK by the server which also disappears - finally, the workstation gets tired of waiting and the connecting application fails - several minutes later the glitch magically clears up, and the missing SYNACKs are sent to the workstation, which RSTs them. - everything works later on I haven't discovered a method to reproduce this behaviour, and my sysadminning is only part time here, as I have windows coding to do. The detective work I mentioned was done several weeks ago, and the local LUG here classified it as a nat/conntrack bug. I...

[Bug 693] SNAT is failing to maquerade some TCP RST packets
...addresses. But I was testing something else, and while looking at this interface with a packet capture, I accidentally noticed that a public internet interface was occasionally sending packets sourced from internal private machines, using an RFC1918 address as the source address. These were FIN and RSTs, only, just like you say. Unlike some of you, I use a front-end for IPtables that makes use of perl scripting (which in the end, scripts IPtables similarly in the way most of you are also scripting your policies). So then I composed a huge bug report that I was going to submit to the developer of...

state INVALID
Having moved from a "cascading LANs" configuration to two independent LANs on eth0 and eth1, I still get some "state INVALID" for which I am not sure what the cause is. Can somebody help me understand its probable origin? Thanks, Costantino [see attachment]

use keep state(strict) to mitigate tcp issues?
Hi, When deploying a BSD with IPF in at the network perimeter and using rules like these: pass in .. proto tcp ... keep state(strict) it's possible to refuse tcp packets which arrive out of order. This would increase the difficulty doing blind attack resets and blind data injection attack, cause then you'd have to "guess" the exact expected number. Checpoint has a similar
