event id 5807

Tuesday, March 27, 2018 - Posted by Keith A. Smith, in Microsoft

I recently encountered a rare event log entry event id 5807

During the past 4.22 hours there have been 24 connections to this Domain Controller from client machines whose IP addresses don't map to any of the existing sites in the enterprise. Those clients, therefore, have undefined sites and may connect to any Domain Controller including those that are in far distant locations from the clients. A client's site is determined by the mapping of its subnet to one of the existing sites. To move the above clients to one of the sites, please consider creating subnet object(s) covering the above IP addresses with mapping to one of the existing sites.  The names and IP addresses of the clients in question have been logged on this computer in the following log file '%SystemRoot%\debug\netlogon.log' and, potentially, in the log file '%SystemRoot%\debug\netlogon.bak' created if the former log becomes full. The log(s) may contain additional unrelated debugging information. To filter out the needed information, please search for lines which contain text 'NO_CLIENT_SITE:'. The first word after this string is the client name and the second word is the client IP address. The maximum size of the log(s) is controlled by the following registry DWORD value 'HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters\LogFileMaxSize'; the default is 20000000 bytes.  The current maximum size is 20000000 bytes.  To set a different maximum size, create the above registry value and set the desired maximum size in bytes.

After doing a search for netlogon.log and taking a closer look at the netlogon.log file, I noticed that it doesn’t record the year of each entry, just the day and month.  I scrolling down to the bottom and all the most recent entries, I noticed that the ip address range had not been defined in AD Sites and Services.  The IP’s were from laptops connecting through the VPN which was assigning a completely different subnet,  so I just added the VPN subnet and everything was fine after that.

Why you should review your ISP Advertising and Marketing Preferences

Sunday, March 11, 2018 - Posted by Keith A. Smith, in Security

I was recently asked by a colleague of my mine if it was possible that Comcast could be targeting ads based content that was viewed while using the services. I said “it’s possible if you haven’t opted out of anything preferences” typically service providers automatically opt-in customers into data collection practices now. My colleague logged into the account —> went into settings then clicked on communications & ad preferences to find 4 very interesting area’s under “Advertising Preferences” and “Marketing Preferences”

My colleague clicked on the edit for the cable targeted advertising and was shocked to see that the opt in box was checked and immediately switched to Opt out for advanced advertising preferences: activity data and ad groups. On the same page we saw links to the privacy notice and the FAQ for advanced advertising preferences, the privacy policy clearly stated that

We also collect information about your account and your use of the Services, which may include:
    •    your account number;
    •    billing, payment, and deposit history;
    •    maintenance information;
    •    the types of Services to which you subscribe;
    •    the device identifiers and network addresses of equipment used with your account;
    •    voice commands;
    •    video and audio recordings;
    •    records indicating the number and types of devices connected to our network;
    •    technical information about your Service-related devices, including customization settings and preferences;
    •    network traffic data;
    •    information about your use of the Services and their features, including video activity data, as well as Internet or online information such as web addresses and other activity data in order to render Internet service; and
    •    additional information about the Service options you have chosen.

"When you use the Services, our cable system automatically generates, transmits, and collects much of this information as part of providing the Services to you. For example, we receive information about the use of set-top boxes, remote controls, program guides, video players, applications, and other devices and software connected to our cable system (“video activity data”). The video activity data includes, for example, which channels, programs, and advertisements are viewed and for how long. It may also include information about navigation through program guides and applications, and use of devices like remote controls and tablets. If you select various features of our equipment, such as voice commands or search, we also will collect and process the data needed to fulfill your requests."

As we continued to review the notices and policies we saw more of information which led to me suggest the use of a VPN service, there are many providers of this service now and most of in the IT field have started suggesting this more frequently.

Kanboard

Friday, January 19, 2018 - Posted by Keith A. Smith, in Linux

What is kanboard?

Kanboard is an opensource web hosted project management software. So far I think it’s pretty damn cool. It has all the features of the top paid project management solutions out there with the little added bonus of it being free.

The “cost” for anyone working with FOSS will be the setup time. This was my first time trying to setup Kanboard so I figured I would post how it went, I did encounter some stumbling blocks  so I noted the solutions I used to get the installation up and running. Hopefully this will reduce the “cost” for you.

I tested this on Ubuntu Xenial 16.04 LTS

Installation

  1. sudo apt-get update and upgrade
  2. sudo apt-get install -y apache2 libapache2-mod-php7.0 php7.0-cli php7.0-mbstring php7.0-sqlite3 \  php7.0-opcache php7.0-json php7.0-mysql php7.0-pgsql php7.0-ldap php7.0-gd
  3. cd /var/www/html
  4. sudo apt-get install php-xml
  5. sudo apt-get update && apt-get install git
  6. sudo git clone https://github.com/kanboard/kanboard.git
  7. chown -R www-data:www-data kanboard/data
  8. Reboot
  9. Try the url http://hostname/kanboard








I commented out the two bottom lines to make it work.

// Credentials for authentication on the SMTP server (not mandatory)
define('MAIL_SMTP_USERNAME', 'username');
define('MAIL_SMTP_PASSWORD', 'super password');




Errors I encountered

Internal Error: PHP extension required: “pdo_sqlite”

Solution: Run the following in the terminal window

sudo apt-get install php7.0-sqlite



Internal Error: This PHP extension is required: "dom".

sudo apt-get install php-xml

See Ya to 2017!!!

Sunday, December 31, 2017 - Posted by Keith A. Smith, in Journal of thoughts

Well, 2017 is soon to be over...at least in my time zone. For me, I can certainly say that in 2017 the going up was worth the coming down. It's been another year of growth both personally and professionally. In 2018, there will be many new adventures and experiences. Some I am aware of already and many that are undiscovered.

With that being said, I close 2017 out like this. The past is history, tomorrow is a mystery, and today is gift that's why they call it the present!!

On to a new chapter

Monday, December 11, 2017 - Posted by Keith A. Smith, in Journal of thoughts

Today was my last day at SIFF as CTO. It's been one hell of a year! I am proud to have spearheaded over 30 major projects in the Infrastructure, Security, and Business Application arena and saw them to completion. I look back at my time here with pride knowing that in the technological sense, it was truly a night and day transformation since I joined.


I've always tried to capture before and after pic's of things because pictures always tell a unique story. Below is one of my favorite photos, it literally represents all the technical transformation I spearheaded.
Before
After





Next chapter starts in a few weeks!
