When USPS Informed Delivery was announced, I was genuinely excited.

After years of maintaining a complex WordPress-based blog, Linux servers, and a Datacenter Colo, I decided it was time to simplify.

If you did not know about this - you should be very worried.

A long time ago I became frustrated with having to update my WordPress plugins manually, so I created a Perl script and a blog post (vpetkov.net/2011/08/03/script-to-upgrade-plugins-on-wordpress-to-the-latest-version-fully-automatically/) that explained h…

NOTE: Updated code 10-27-2018 In this day and age where everything is measured, recorded, and available remotely (via a REST API most of the time!)

You need to connect to a Cisco AnyConnect (or Juniper Pulse Connect) VPN, and you cannot stand the default client for a variety of reasons (slow connects, crashes, unable to start, pointless pop-up notifications, crashes, pid-loss, etc), and so, you look…

I needed a way to monitor Docker resource usage and metrics (CPU, Memory, Network, Disk).

If you have not used Swarm, skim the non-service-discovery tutorial to get a feel for how it works: vpetkov.net/2015/12/07/docker-swarm-tutorial-and-examples.

[ updated 10-30-2016 | Upgraded Plex to plexmediaserver-1.1.4.2757-24ffd60.x86_64.rpm and CentOS ] Recently I tried setting up a Plex server in a docker container.

This problem starter as a rather simple one - I needed to send HTML emails, using Perl, to a remote SMTP server with user authentication and TLS support (STARTTLS).

The guys at Qualys discovered a very interesting buffer overflow in the __nss_hostname_digits_dots() function of glibc.

Lately, we have seen some really bad vulnerabilities in regards to SSL (Heartbleed) and Bash (later dubbed “Shellshock”), along with some slightly “lighter” linux/open source ones.

As some of you may have heard, a very serious remote vulnerability was discovered disclosed today within bash.

UPDATE: Insecure has released v6.46 which contains all of these patches.

There are many ways to exploit a web server and gain access to the file system - read or write (sometimes both).

Setting up the network interfaces is something that seems to give people a hard time (clearly visible here: http://docs.openstack.org/grizzly/basic-install/apt/content/basic-install_network.html).

Recently, while setting up my the network controller for OpenStack, I saw this message: # tail -f /var/log/quantum/openvswitch-agent.log ERROR [quantum.plugins.openvswitch.agent.ovs_quantum_agent] Failed to create OVS patch port.
