Posted January 28, 2012 By Landis VNTPD and the Terrible, Horrible, No Good, Very Bad Listening Sockets
Posted January 28, 2012 By Landis VTrying to get ntpd to stop creating listening sockets is a royal pain in the ass. Sure, I can set a firewall rule that blocks access to the port on undesired interfaces, but it's more work to make that happen, and it's just not as clean. Here's what I finally ended up doing to stop creating default (0.0.0.0:123 for IPv4 and :::123 for IPv6) listeners and just set a listening socket on one address on my internal interface. Hopefully it helps someone else out. # Add to ntp.conf, in order interface ignore all interface ignore ipv4 interface ignore ipv6 interface listen 192.168.0.1
While there’s not a gaping security window with NTP, I just feel a little safer not having anything listening at all.
- My sentiments exactly! Glad I could help.
- thank you!!! "interface ignore all" doesn't stop listening on all sockets and this doesn't make sense... We need to ignore…
WordPress Plugin Failure
Posted January 7, 2012 By Landis VAfter a recent WordPress upgrade, I found myself unable to log in again and was receiving HTTP 500 messages. Kudos to Jeff for his post at http://perishablepress.com/press/2008/02/18/quickly-disable-or-enable-all-wordpress-plugins-via-the-database/ for the quick backend disable of plugins through the database. I’m sure there are other posts describing the process out there, but his came up near the top of Google’s results for my search and were very simple and straightforward – and solved the problem in short order. Fortunately I wasn’t under his time crunch to get things fixed, but I appreciate his documenting the fix after the fact.

They don’t pay you for the use of this data – your data – that they turn around and use to bilk even more money out of you.

Posted October 27, 2011 By Landis Vhttp://iscs.sourceforge.net/ ISCS administrators do not configure the security subsystems separately. They never write a single order dependent rule or complex security association. They describe the security environment in functional, practical, process oriented terms such as, “Sales needs access to Sales Data”, “Marketing, Financial, Engineering and the outside Advertising Agency need access to the New Product Line data”, “the 192.168.1.0/24 network should participate in the VPN”, “the new acquisition’s 10.1.1.0/24 network needs to NAT globally to 172.16.8.0/24 to avoid conflict with the existing 10.1.1.0/24 network” or “the credit card database servers should not be allowed to send packets any further than the e-commerce web server in the DMZ to prevent data theft over the Internet.”

Really, really need to take some time to play with cfengine.
Had a funny thought about Apple (of the garden) being treated like a religion, “meticulous management of customer experience” (i.e., “herding the flock”), and suddenly it’s now the Rapture.

Would be nice to have a ping command with a configurable (via command line switches) exponential weighted moving average for packet loss. That way, you could watch some statistics on loss over intervals while running from a command line, and not just be interpreting loss for the time since you started the command an hour (day/week/whatever) earlier.

Data visualization tools
Posted April 29, 2011 By Landis VComputerWorld recently posted an article with information on 22 free tools for data visualization. I’ve run across a few of these in the past. Still need to put some focus on learning statistics principles to be able to better use the data. Until then, this link will help me keep track of them.
