In the Haktip Darren goes over a couple ways to identify web servers from the command line.

Wayno from pkill-9 sent this by. Two quick and dirty ways to ID a web server.

First way

curl -I www.hak5.org

Should result in

HTTP/1.1 200 OK
Date: Tue, 05 Apr 2011 01:00:09 GMT
Server: Apache/2.2.15 (Unix) mod_ssl/2.2.15 OpenSSL/0.9.8e-fips-rhel5 mod_auth_passthrough/
2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 PHP/5.2.9

The second, geekier way is to do it with telnet.

telnet www.hak5.org 80

What’s more wicked than a screen session? Two screen sessions! As we’ve talked about recently the unix command Screen is a great way to maintain bash sessions from multiple SSH clients without losing your work.

My favorite shortcut after invoking the “screen” command is CTRL+a followed by “S”, which splits the screen horizontally in two. Use CTRL+a then Tab to switch between the views. Debian users get the added sexyness of vertical split by hitting CTRL+a then Pipe.

Belvedere lets you organize any folders on your harddrive. You can create rules to move, copy, delete, rename, or open files based on name, extension, size, creation, date, and even more.

So basically it’s a self-cleaner tool for Windows Only. There’s also a Mac cleaner called Hazel that you might want to check out if you are an Apple user.It was created by Adam Pash back in ’08, and you can check out the source of this tool over at GitHub.It’s a .exe so just install it from the download link. You can make Belvedere startup when Windows starts, but you’ll have to add it manually.

How you use it: Belvedere is really easy to use, it’s just simple point and clicks. You create a folder, then name your rule from one of the choices, and build conditions with the drop down menus. Belvedere gives me the ability to multitask and not worry so much about how clean my PC is. Do you have another tool that works like Belve? Let me know at feedback@hak5.org.

Building a virtualization clusters with proxmox on the cheap and demonstrating how to migrate virtual machine.

Virtio drivers and paravirtualization explained while building a live Proxmox cluster migrating virtual machines using the Virtio drivers.

Go open source in your virtual server platform with Proxmox-VE. This walkthrough will go show the steps of setting up a Proxmox server that will allow you to run virtual machines and manage with a webclient.

Virtualization of physical versions of something such as a server or router is a way to minimize rack space and power consumption. So something like Proxmox will give those benefits and also the ability to do easy backups & load balancing. This also provided the work space for things like creating a virtual test network for hacking; running services such as home media servers. Proxmox VE supports OpenVZ which is a OS level virtualization via Linux kernel Isolated containers; this allows for performance speeds close to native running on its own hardware. It also has full virtualization KVM Kernel-based Virtual Machine Supports which will also give the machine complete hardware and kernel independence from the Linux host machine allowing for running OSes like windows. Some of the hardware requirements for Proxmox VE 64-bit Intel or AMD processors Intel-VT or AMD-V for KVM 1+ GB RAM, 4+ GB or better of hard drive storage (it does support RAIDS) and any network interface cards supported by Debian Lenny 64bit

Installation

You can install on top of Debian Lenny but it’s easier to do a fresh install Download, burn and boot from ISO.

In this segment Darren continues to show how to securely forwarding X11 over SSH so you can use Linux GUI tools in anywhere — even on Windows.

As explained in Part 1, all you need do open GUI apps over SSH is an SSH client and an X11 server. If you’re on Windows this can be achieved with Xming and Putty. Darren demos using an XP VM.

In this segment Darren shows how to securely forwarding X11 over SSH so you can use Linux GUI tools in anywhere — even on Windows.

While SSH is great for getting a bash terminal on a remote Linux box, a few paramaters and an X11 server can take it to the next level by running X Window graphical applications over your secure tunnel.

In this segment Darren demos launching GUI apps from one Linux box to another using ssh -X.

Shannon joins us to show off Katana — the happy hackers boot key

Katana is a multi boot USB key that has a focus on some o-so-familiar suite of security tools.

Darren checks out screen recording solutions for Linux.

First he checks out GTK RecordMyDesktop. Then uses mencoder to convert some of the recordings. Also shows off how to record screen with ffmpeg and setting it with an alias.

A Virtual Appliance can be though of as a software image containing a supporting stack designed to run inside a virtual machine. A quick look at vmware’s virtual appliance directory shows that there are hundreds of applications that can be quickly and easily deployed. In this segment I take the Dimdim open source virtual appliance, designed for vmware, and deploy it with VirtualBox (just becasue I can).

Joe Switch writes in to ask what the deal is with Virtual Routers and other such untangable networks. Matt has the answer. The way I understand it your more high end (read: expensive) Cisco and Juniper routers have virtual routers built in — much like you might have a virtual interface like eth0:1 in Linux — to manage VLANS, IP subnets and such.

Matt goes on to explain that in the vSphere product by VMware you can use the APIs to write, basically, a software based switch to compliment your existing deployments. Check out the Cisco Nexus 1000V. It’s a software implementation of a Cisco Nexus switch. I’d love to get my hands on it but at nearly $1000/year I’ll find something open source. Speaking of which, we’ve been meaning to play with a Cisco virtual network application but are in need of an ISO. If you’re privy to an open source alternative or can help out drop us a line.
