  • Resolve Hardware Status Alert SEL_FULLNESS | Brian Ragazzi – […] I noticed an alert on two UCS B250M2 hosts in the vSphere Client. The alert Name was “Status of other host hardware objects”. This isn’t helpful. To get more information, you have to navigate to the Hardware Status tab of the host properties. Here I saw more information about the alert. It’s cryptically named “System Board 0 SEL_FULLNESS”. […]
  • Network Stack: Cisco ASA Packet Capture – […] The ASA platform has fantastic built-in packet capture capabilities which can come in very handy for troubleshooting issues. I will be demonstrating some of the capabilities using an ASA 5505 running version 9.0(1).Performing a packet capture is done using the capture command from privileged exec mode. […][ Fantastic… I won’t say that ]
  • Sanesecurity ClamAV Malware, Phishing, and Spam Signatures – Sanesecurity produces add-ons signatures to help improve the ClamAV detection rate on Zero-Day malware and even on Zero-Hour malware. Since 2006 we have provided professional quality ClamAV signatures to protect against the following email types: Macro malware, Zip malware, Rar malware, Javascript malware, 7z malware, Phishing, Spear phishing and other types of common emailed malware and spam. Sanesecurity 3rd Party ClamAV signatures can also help prevent TeslaCrypt, Cryptowall, Cryptolocker and other ransomware, who’s source usually starts as a malicious email.
  • Multistage environments with Ansible – Ross Tuck – Ansible has excellent documentation but one thing I was confused about was the best way to store the configuration for multistage projects: say, different passwords for dev, staging, production. This isn’t really covered in the ansible-examples repo because it’s specific to your project and while the documentation has recommendations, it doesn’t spell it out completely (which I need since I’m an idiot).

  • One Thing Well | Let’s Encrypt – Let’s Encrypt is now in public beta and offers a command line tool that makes the process of getting and renewing certificates easy, but you have to run it as root, and it’s designed to rewrite your web server’s configuration files. Here’s a selection of alternative tools and clients:
  • Tsung – It can be used to stress HTTP, WebDAV, SOAP, PostgreSQL, MySQL, LDAP and Jabber/XMPP servers. Tsung is a free software released under the GPLv2 license. The purpose of Tsung is to simulate users in order to test the scalability and performance of IP based client/server applications. You can use it to do load and stress testing of your servers. Many protocols have been implemented and tested, and it can be easily extended. It can be distributed on several client machines and is able to simulate hundreds of thousands of virtual users concurrently (or even millions if you have enough hardware …). Tsung is developed in Erlang, an open-source language made by Ericsson for building robust fault-tolerant distributed applications. [ via http://onethingwell.org/post/134852940551/tsung ]
  • Internet Redundancy with ASA SLA and IPSec – PacketU – I’ve seen a lot of examples of redundant Internet connections that use SLA to track a primary connection. The logic is that the primary Internet connection is constantly being validated by pinging something on that ISP’s network and routing floats over to a secondary service provider in the event of a failure. I was recently challenged with how this interacted with IPSec. As a result I built out this configuration and performed some fairly extensive testing.

  • Can’t SSH into ASA? « Axelilly’s Ponderings – Something strange happened today when I went to SSH into my ASA cluster.

    Upon running ssh I got this error message:

    ssh_exchange_identification: Connection closed by remote host

  • Ubuntu Linux Resources – It's a collection of tutorials designed to help new Ubuntu users, in particular those coming from a Windows-using background.
  • PsPasswd – Systems administrators that manage local administrative accounts on multiple computers regularly need to change the account password as part of standard security practices. PsPasswd is a tool that lets you change an account password on the local or remote systems, enabling administrators to create batch files that run PsPasswd against the computers they manage in order to perform a mass change of the administrator password.

    PsPasswd uses Windows password reset APIs, so does not send passwords over the network in the clear.

  • Configuring a site-to-site VPN between a Sonicwall and Linux Openswan – Mike A. Leonetti – I have had the fortune of having the challenge to set up a site-to-site (or BOVPN/Branch Office VPN) between a Sonicwall and Openswan. I have searched for other articles that cover this topic and found plenty of information that got me far enough to get some of it working. However, getting the whole thing working took quite some time and I found the guides to be incomplete. So for the sake of even my own remembrance, I will write a mini guide up. Of course I will link all of the guides I've used in a references section.
  • VPN Site-to-Site Openswan x ASA (Cisco) – House of Linux – Ladies and gentleman, today I am going to demonstrate how to integrate technologies from different platforms. It is possible to use Cisco to integrate with Windows and Linux using protocol such as LDAP. In this case the communication between Linux and ASA (Adaptive Security Appliances) is straight. We will only need to check the cryptography configuration and that it, the connection is established.
