Welcome to Jetstream!

Welcome to my homeserver, called Jetstream. What is Jetstream you may ask? Jetstream is a virtual machine that is running CentOS 6.5 Linux on my laptop. I use VirtualBox and it's quite stable. Probably my most favorite hypervisor is VirtualBox. Jetstream's specs are 512MB of RAM, 512MB swap, Intel Core 2 Duo T5850 2.16GHz, 20GB HDD. Jetstream's network is CenturyLink (Embarq Tier) with 6Mbps down, and 0.50Mbps up. It was 0.80Mbps upload, until awful CenturyLink bought Embarq and said, "we don't offer that anymore!" Worst company ever! I use a CDN to load balance some of the things on this site, for instance the cascade style sheets. My lovely 2Wire router/modem powers the network for Jetstream. My 2Wire runs a variant of BSD and is actually a decent residential gateway! I really love it's professional-grade firewall and it's ability to syslog and change more advance settings such as what NTP servers to use. I've been trying to find a way to gain SSH access to my 2Wire. I run a syslog host on Jetstream, and my 2wire outputs the logs to it. I can then tail -f them into the #ControlDeck IRC channel for live inspection of my network. The 2Wire is much more stable than the Westell router I had. On a good month when nobody touches me, I can achieve 100% uptime. What does Jetstream do you may ask? For one, it gives me a playground to work around and learn Linux. I just started Linux about 4 years ago, and I'm learning rapidly. Jetstream also is a contributing server to GTAXLnet IRC.Jetstream runs an NTP server, DNS server (bind9), and DHCPd for my LAN network. Jetstream is also plays a major roll in GTAXLnet DEFCON, scanning the entire internet. Chances are, you've been touched by Jetstream. So yeah, look around and you might find something useful.

Jetstream Status


I take uptime very seriously. I monitor system uptime and network uptime. Network uptime is monitored via Pingdom, which probes TCP port 6667 (IRC) every minute from multiple geographic diverse servers, making the uptime results highly accurate. Jetstream stays on 24/7 for the most part. I've had system uptime up to 19 weeks! I strive to reach 250 days before maintenance. Jestream being a laptop, requires a lot of maintenance. For instance, I had to replace the CPU fan in Jetstream in February 2014. This required me to tear Jetstream completely apart, including the screen, and even the motherboard. Here is a picture, and another one here. You can view more that maintenance on my Instagram page. As for network uptime, there are several factors that can play a roll in downtime. The main ones are: maintenance, CenturyLink faults, storms, and Denial of Service attacks. You can view Jetstream's network uptime here. I try to maintain 95% uptime per given month, although sometimes this is hard to achieve. We do not guarantee uptime, although we do strive.
Here is a brief summary of Jetstream's network uptime:
November 2013: 99.99%
December 2013: 99.90%
January 2014: 99.43%
February 2014: 96.37%

Firewall Monitor

I monitor all attacks and dropped packets that hit my servers. This includes, but not limited to: UDP Floods, SYN Floods, ICMP Floods, TCP Port Probes, TCP Port Scans, UDP Port Scans, NULL attacks, etc. At this time I only monitor dropped traffic on Jetstream. I even watch every single port that gets probed. If a port keeps getting probed within a certain threshold, I will then enlist it in the Firewall Monitor. This Firewall Monitor is for the purpose for education and to publicly expose all attackers that touch my IP. The website version doesn't contain as much information as my copy, and the website version is not live. I will try to update it at least weekly. If you feel your IP is wrongfully listed in my Firewall Monitor, and want it removed, just contact me and I will remove it from the Web Version if I feel inclined to. Please note, it is possible to spoof the IP header on some of these attacks, this cannot be verified and there is nothing anyone can do about it except the attacker's ISP.

DNS Amplification/Reflection Firewall

This is no longer being maintained. Sorry for the inconvenience! This logged all scanners searching for domain name servers that allow recursive queries for use for DNS amplification/reflection denial of service attacks. You can still view what we had logged by clicking the button below. The major were Ecatel servers, due to Ecatel having no egress filtering for spoofed IP headers. Many attackers scan and perform their attacks from the same server (Ecatel).
