Re: Offline NTP time sync

My question is even more fundamental than that. He claimed "... we all know that best secure option is to use in offline mode and connected to internet via VPN /firewall access." For one: If it's "connected to the Internet" it's not off-line. And they'd have to break EyezOn's en...

Re: Envisalink - TPI Documentation

With only SSH access, tcpdump -p -n -i <interface> -X -s0 -w capturefile.pcap host <ip address> is my go-to, and then just scp/rsync the capturefile.pcap file to your computer and open in Wireshark. Yeah, it's almost certainly the re-use of the source port which is causing it. Since the EVL never dr...

Re: Envisalink - TPI Documentation

My first response is, what does a tcpdump/wireshark packet capture show?

I've used LUA a couple times but never with sockets. Is it re-using the source port? If so, can you fix it so it uses a random source port for each connection?

This should probably be a new thread...

Send a 001 "status report" and one of the things you'll get back is a 65x - a 650 or 653 means it's ready but not armed while a 652 is already armed.

Re: The Internet of Insecure Things

When I bought our home, the very first thing I did was contact a local, reputable locksmith and have all the locks re-keyed. If I had not done that, and somebody'd subsequently burgled the home, would that have been the seller's fault, for failing to re-key all the locks for me? What, no blame on t...

Re: The Internet of Insecure Things

That attitude was fine 10 years ago, but nowadays it is completely unacceptable. Speaking as an IT professional with better than 25 years experience in the field: I disagree. Put quite simply: Anybody who exposes their private LAN to the Internet such that IoT devices are readily-accessible by conn...

Re: The Internet of Insecure Things

That attitude was fine 10 years ago, but nowadays it is completely unacceptable. You will be singing a different tune when it is your server/network which is down because of a massive DDoS attack. The Oct 21st attack which brought down Dyn was caused by IoIT devices with default passwords. Users hav...

The Internet of Insecure Things

In this day and age of botnets taking over random IoIT, having a single default user/pass for everything is beyond stupid. At the absolute minimum the password should be the last 4 digits of the MAC or something, though a true random per-device password would be best. I just did a Shodan search. It ...
