  • How to use Powershell in an exploit · rapid7/metasploit-framework Wiki
    PowerShell is a scripting language developed by Microsoft. It provides API access to almost everything in a Windows platform, less detectable by countermeasures, easy to learn, therefore it is incredibly powerful for penetration testing during post exploitation, or exploit development for payload execution. Take Metasploit’s windows/smb/psexec_psh.rb module for example: it mimics the psexec utility from SysInternals, the payload is compressed and executed from the command line, which allows it to be somewhat stealthy against antivirus. There’s only less than 30 lines of code in psexec_psh.rb (excluding the metadata that describes what the module is about), because most of the work is done by the Powershell mixin, nothing is easier than that. The command line will automatically attempt to detect the architecture (x86 or x86_64) that it is being run in, as well as the payload architecture that it contains. If there is a mismatch it will spawn the correct PowerShell architecture to inject the payload into, so there is no need to worry about the architecture of the target system.

  • VMware: Add PortGroup to all hosts in cluster with PowerCLI – […]
    Today we configured a new VLAN on the physical switches, now we need to configure a portgroup with vlan id on multiple ESX hosts in our cluster. To do this by hand it will cost 3 minutes per host, to script this.. you configure this in 10 seconds![…]

  • LVM Loopback HOW-TO | Anthony’s Blog – This is a simple tutorial on setting up LVM on loopback devices, I’ve used it a few times for creating dynamic virtual disks; it came in particularly handy when archiving NEXRAD radar data for my radarwatchd project – using up all your inodes on several hundreds of thousands of 15Kb files doesn’t sound like my idea of fun. Creating a virtual volume with reiserfs was a particularly handy solution in this case.

  • How to create an RPM package – FedoraProject – This page describes in detail how to create an RPM package, and in particular, how to create a SPEC file. Unlike other RPM guides, this page explains the specifics for Fedora with links to Fedora-specific guidelines. Since it is maintained through the Fedora Wiki, it is likely to be more up-to-date than other guides. Despite the focus on Fedora, most of this document does apply to other RPM-based distributions.
  • How To Install Elasticsearch, Logstash, and Kibana 4 on CentOS 7 | DigitalOcean – In this tutorial, we will go over the installation of the Elasticsearch ELK Stack on CentOS 7—that is, Elasticsearch 1.4.4, Logstash 1.5.0, and Kibana 4. We will also show you how to configure it to gather and visualize the syslogs of your systems in a centralized location. Logstash is an open source tool for collecting, parsing, and storing logs for future use. Kibana 4 is a web interface that can be used to search and view the logs that Logstash has indexed. Both of these tools are based on Elasticsearch.

  • Step by Step Installation and Configuration of OpenLDAP as Proxy to Active Directory | haroonferoze – This guide describes how to install and configure OpenLDAP as proxy to Active Directory.
  • Integrate Active Directory and OpenLDAP | Networking content from Windows IT Pro – OpenLDAP’s proxy service can allow LDAP operations to cross the boundaries between AD and OpenLDAP deployments. To demonstrate this proxy service, we walk through the steps to make AD’s cn=Users container, which by default contains all user objects, part of an OpenLDAP directory. To produce the examples in this article, I used CentOS 4.3, OpenLDAP 2.2.13, and AD running on Windows Server 2003 R2. Later in the article, I’ll show you a limitation in the commonly deployed OpenLDAP 2.2, which you can solve by installing OpenLDAP 2.3 on CentOS 4.3.
  • Let’s Chat — Self-hosted chat for small teams – WHAT IS THIS THING? Some backstory. Way back in 2012, we didn't like any of the existing chat services out there. So we decided to write our own. Let's Chat is a persistent messaging application that runs on Node.js and MongoDB. It's designed to be easily deployable and fits well with small, intimate teams. It's free (MIT licensed) and ships with killer features such as LDAP/Kerberos authentication, a REST-like API and XMPP support. Let's Chat is a side-project of the development team at Security Compass. (A real life 10% time project!)

  • SSH_VPN – Community Help Wiki – This page discusses using SSH to set up SSH-based point to point connections, which can then be used to create routes that create virtual private networks. Note that using SSH in this fashion is not the "best" way to create a permanent, stable VPN. Notably, SSH uses TCP, and TCP over TCP can provide abysmal performance under pathological conditions.
  • VPN over SSH – This how-to is intended to cover the details of how to establish a VPN (Virtual Private Network) over a SSH connection. Starting with open-ssh 4.3, you can now use a ssh connection to set up a VPN. This is technically termed "layer-3 IP-in-SSH tunnelling" and is not using ssh to port forward (ssh -L ) or create a dynamic "application level" forwarding (SOCKS) (ssh -D ). Rather a VPN is established using a SSH connection to create a virtual interface, tun0. Advantages : IMO, this technique is easier to set up then openvpn, especially if you are using a single client. Works with most Linux distributions without the need to install any additional software on the clients. The server only needs openssh-server. This protocol uses udp to transmit tunneled tcp connections resulting in a more stable connection compared with port forwarding (using ssh with the -L or -D options). Disadvantages : As of yet I do not know of a windows client which will use this protocol. If you are needing to set up a VPN with numerous clients I would use openvpn. Although there are several "how-to's" on the web, most of them assume you know something about networking and routing. This page attempts to explain some of the "missing details".

  • Enterprise/Authentication/sssd – Ubuntu Wiki – The sssd authentication in Ubuntu works pretty decently. You can use it basically with any directory-style backend, including OpenLDAP, Kerberos, RedHat's FreeIPA and Microsoft's Active Directory. The good part about sssd is that it can be used to log into multiple directory services, so if you have some users in one directory, and the the rest in a different place, this works pretty decently in sssd. You can use it for single-server deployments with plain LDAP with servers or workstations (where you could as well go with pam-ldap and nss-ldap), but also, or especially for more sophisticated setups.
