A Dynamic Watermarking Technique for Matching Communication Addresses with Cars in a Visual Field
We consider a problem faced by an intelligent roadside unit (RSU) monitoring a roadway by a video camera. Suppose the RSU notices that a particular car in its visual field needs to execute a specific evasive maneuver to avoid danger. It would like to send a packet addressed to that particular car with this suggestion. The problem is that while all the cars are communicating with the RSU, the RSU does not know which car in the video is associated with what IP address. So, it does not know which …

TIL why I can't access release files from open-source projects on GitHub anymore.
It seems that the IP for release-assets.githubusercontent.com got added to ipthreat.net list:

Malware is actually being distributed via GitHub, but the majorit…

Ah, a free update on the state of the legacy IP address market, from a spammer:
Subject: Spanish IPs ranges available
We currently have a very competitive offer on IP sales, with the following prices:
• €27/IP for ranges from /24 to /22
• €26/IP for ranges of /21 and larger

Off-Path TCP Exploits: PMTUD Breaks TCP Connection Isolation in IP Address Sharing Scenarios
Path MTU Discovery (PMTUD) and IP address sharing are integral aspects of modern Internet infrastructure. In this paper, we investigate the security vulnerabilities associated with PMTUD within the context of prevalent IP address sharing practices. We reveal that PMTUD is inadequately designed to handle IP address sharing, creating vulnerabilities that attackers can exploit to perform off-path TCP hijacking attacks. We demonstrate that by observing the path MTU value determined by a server for …

STM32MP2 PCIe bringup update: the PCIe IP has 4 MB of address space allocated to it, but touching anything past the first 2 MB seems to hang.
When I dump any of the register blocks in the first 2 MB, they all report the same Synopsys : 0550 device ID.
All of the registers are the same in each of the mirrors, with the exception of 8 bytes starting at 0x174 and 4 bytes starting at 0x728.
Somehow there has to be a way to see devices behind the root complex.

More legacy edu space likely to be used for hosting.
Not immediately obvious who or what steel-axis is to me, and who they represent. They have a virtual business address in Delaware, a gmail email, and a RIR database contact address in Israel. RIPE-based LIR that has gotten a number of transfers over the years, usually ending up being used by India-based HostRoyale.

I thought Arthur Andersen folded after #Enron? Wonder why they still have a /16, among which is a server impersonating a bunch of #Amazon hosts...

@… I'm curious to hear people's thoughts on securing publicly available software running at home.
I'm thinking about running my mastodon instance at home instead of DigitalOcean, but that means publicly advertising my home IP address on the web. Putting that behind a VPN or similar isn't an option because other servers have to reach mine r…

Accelerated Convolutive Transfer Function-Based Multichannel NMF Using Iterative Source Steering
Among numerous blind source separation (BSS) methods, convolutive transfer function-based multichannel non-negative matrix factorization (CTF-MNMF) has demonstrated strong performance in highly reverberant environments by modeling multi-frame correlations of delayed source signals. However, its practical deployment is hindered by the high computational cost associated with the iterative projection (IP) update rule, which requires matrix inversion for each source. To address this issue, we propo…

TL;DR
Document your network!!!! And if not, keep your actions in the right order to not waste a lot of time.

Last week I wanted to check something on my network switch and tried to open the web interface at the IP address I remembered. Unable to connect.
I was short of time as always so I put this back on my 'to-do' list.
Yesterday I had 25mins to spare... So I took a look at the internet router which maintains a list of all active network devices. Na…

Do I know any C programmers?
I’m fiddling with a 20yo *trivial* C program and my editor(!) is warning me about the twisted casts in the first line of this:
if ((int)(addr = (void *)inet_addr(argv[1])) == -1) {
errnum=errno;
strerror(errnum);
perror("ERRNO");
(void) printf("IP address must be of the form a.b.c.d\n");
exit (2);
}
I can no longer understand what I was thinking. Can anyo…
