Hi, One of our AWS machines was used in an DOS attack last night and I am looking for possible attack vectors. AWS tells me it was sending UDP port 0 traffic to a cloudflare address. This instance had an incorrectly configured AWS security group exposing all ports. The server in question is a Centos 7 based FreeIPA server, OpenVPN concentrator and DNS server. With a brief inspection before the

I have the function CN_state_log_sum=function(Tot_log_sum){ #estimate copy number state for the log sum approach if(((Im(Tot_log_sum))!=0)|Re(Tot_log_sum)<=log(1/4)/log(2)) {return(0)}

Given this recent announcement https://www.us-cert.gov/ncas/current-activity/2017/01/16/SMB-Security-Best-Practices How does one turn off and verify the SMB protocol setting? I'm a bit confused by looking at the man page for smb.conf. I have the following set which I believe to be the default settings. samba-tool testparm -v | grep "max protocol" client ipc max

Hi all, I need an help to implement this kind of rules on shorewall: iptables --insert INPUT -p udp --dport 53 -m u32 --u32 "0x28&0xFFDFDFDF=0x055a5a47 && 0x2c&0xDFDFFFDF=0x53540343 && 0x30&0xDFDFFFFF=0x4f4d0000" -j DROP This kind of rules need to block a DNS Amplification Attack.

Yeah, I know, this is statistics, things like that does happen, but this really strange because a poisson distribution with a parameter of 3 shouldn't see the number 1932 very often, but the same,

How can I configure samba4 to be protected against DNS amplification attacks? Is there a way to set the network I want it to be recursive, like in bind9?

agc_gain seemed to fit with the idea of what I wanted to do, it was easy to understand its units and behavior, and freezing it produced the desired results. Also I wanted to cap it, so that's done at the same place, and that definitely works. All I want to do is be able to freeze AGC adaptation and put an upper bound on the AGC (for example, 2x amplification). Both of these things seem

Hi, In addition to GADA, what are the available package in R and bioconductor to analyze amplification, deletion, LOH and indels of CNV, SNP data? Any reference is welcome. Best, Carol

Hello, Can anyone recommend a hardphone that has the following qualities... Both headset and handset ports Headset port has amplification built in Supports SIP using G729 We are switching from a Nortel switch to Asterisk. If anyone is familiar with Nortel phones, the Nortel 2216 phone has the features we're looking for in a SIP phone. Any help would be greatly appreciated. Thank you.

This is directly equivalent to repartitioning and installing CentOS alongside Windows. how many modern cars have DIN mount stereos anymore? almost all have some weird custom shaped dashboard specific stereo insert. sure, you can get DIN

Hi! I have a few questions considering echo cancellation algorithm in Speex: 1. In the manual it's stated that the delay between the input signal and the echo signal must be small. How small should it be? Is for example 100 ms acceptable? 2. Does echo cancellation algorithm deal well with situation, when one of the users of Speex-based VOIP application has "record-what-you-here"

There was a post in the Opus subthread on HA where there was a link to the file called Opus-tools-0.2-34-g98f3ddc_(using_libopus_1.5.2-21-gff6dea5)_Win_GCC142.7z. That's the one I'm currently using. First, I used GoldWave to convert your input file from ?-law to PCM and saved it as a ".wav" file. Next, I encoded it with Opusenc, I decoded its result with Opusdec with the

Hi, I'm currently testing SoftEcho, an echo cancellation software for Asterisk from Octasic. I noticed an important increase of the quality of my coms, but I still have a few echo problems. There is an ERL parameter which corresponds to an initial ERL value probably to optimize the echo training or something in that kind. Is there a way to monitor, using one of the zttools, the instant
