There's a lot of information on the intertoobs about getting ssh-agent "working" in OS X and even more articles about when and how the stock behavior of ssh-agent changed (mostly with respect to how ssh-agent interacted with the Keychain). This article doesn't cover or care about any of that. This article is concerned with: Enabling ssh-agent in such a way that I can "ssh-add" in one terminal window and that same agent (and the loaded keys) is available in all of my other terminal windows.

I wanted to jot down some quick notes relating to running a virtual Firepower sensor on ESXi and how to validate that all the settings are correct for getting traffic from the physical network down into the sensor. Firepower is the name of Cisco's (formerly Sourcefire's) so-called Next-Gen IPS. The IPS comes in many form-factors, including beefy physical appliances, integrated into the ASA firewall, and as a discrete virtual machine. Since the virtual machine (likely) does not sit in-line of ...| packetmischief.ca
In the previous post (Label Switched Multicast - An Introduction) in this series on Label Switched Multicast (LSM) I introduced the concepts behind LSM and draft-rosen, the two most poplar methods for transporting multicast traffic through MPLS Layer 3 VPNs. In this article I will talk through the configuration of LSM on the PE and P routers and get to the point where two CEs are successfully passing multicast traffic via the MPLS network. All of the configuration examples will be relevant to...| packetmischief.ca
There are two common methods for transporting multicast packets within an MPLS-based Layer 3 VPN: Generic Routing Encapsulation (GRE) with Protocol Independent Multicast (PIM) (also known as "draft-rosen") Label Switched Multicast (LSM) There's also a third method which uses Resource Reservation Protocol-Traffic Engineering (RSVP-TE) but I'm not going to get into that one. In this first post in a series on LSM, I'll describe how draft-rosen works, how LSM works, and then compare and contrast ...| packetmischief.ca
Happy New Year! As is my tradition, here are the 2015 blog statistics as compared to 2014. I'm pretty excited that once again readership and overall reach of this blog has increased by double digits. I'm looking forward to growing these numbers and creating challenging and interesting new content in 2016.| packetmischief.ca
