SSH Tunnel – keeping you safe online

2

Category : Android, General, Internet, LAN

I own a HTC Desire HD and I find it extremely handy when it comes to banking online or checking out my social networks.

With the emergence of software such as Firesheep and Faceniff I feel that mobile security is more paramount than ever.

This is where SSH Tunnel comes in. SSH Tunnel allows you to connect to a secure SSH (secure shell) server and pipe all your internet traffic through an encrypted tunnel. Some of the main downfalls of SSH Tunnel are that you need a rooted Android phone, access to a SSH server and a little bit of technical knowledge.

If you are interested in more leave a comment and I can discuss it in more detail.

How to bypass a restrictive firewall using a ssh tunnel

Category : DIY, General, Internet, LAN, Linux

If you are at work or school and you are trapped behind a strict firewall then why not create a tunnel to your home computer and route all the traffic through that tunnel giving you unrestricted internet access.

All these directions are based on using a Linux based computer. I’m sure it can be done in Windows too I just haven’t tried it.

This post describes how to ssh to a personal server using authenticated proxy. SSH (Secure Shell) is typically used to log into a remote machine and execute commands, but it also supports tunneling, forwarding TCP ports and X11 connections; it can transfer files using the associated SFTP or SCP protocols.

Normally we use NetCat to ssh outside using proxy server but if its not support proxy user / pass to authenticate by proxy server and then ssh outside. Here we will use a package called connect.c.

connect.c is the simple relaying command to make network connection via SOCKS and https proxy. It is mainly intended to be used as proxy command of OpenSSH. You can make SSH session beyond the firewall with this command.

This can be achieved by other methods too but this works for me.

1) Download connect.c software.

wget http://www.meadowy.org/~gotoh/ssh/connect.c

2) Compile connect.c Using GCC

gcc connect.c -o connect

and then copy to directory in your PATH i.e /usr/bin or /usr/local/bin

cp connect /usr/bin

3) Congiure ssh_config

append following line

ProxyCommand /usr/bin/connect -H proxy.yourserver.com:8080 %h %p

4) Export Proxy User / Pass as variable

It is insecure but we have to used it. If your proxy doesnt use user/pass for authenticatio, you can skip this.

export HTTP_PROXY_USER=your_username
export HTTP_PROXY_PASSWORD=your_password

Thats it now you can ssh outside without any restriction :)

 

View DELL Service Tag and Express Service Code From Linux and Windows

Category : Internet, LAN

I work with a large number of servers and sometimes I need to get details from the servers when calling Dell technical support. I found a great way to retrieve the service tags from Dell machines remotely. Read below for more info

Get DELL Service Tag on remote Windows system

Login to the Windows remote-host using VNC or remote desktop connection. Use WMIC on Windows to get service tag as shown below.

C:\>wmic bios get serialnumber

SerialNumber

ABCDEF1

Following WMIC command will give make and model number along with service tag.

C:\>wmic csproduct get vendor,name,identifyingnumber

IdentifyingNumber                                Name                                              Vendor

ABCDEF1                                                 PowerEdge 2950                          Dell Inc.

If VNC or remote desktop connection to the remote-host is not available,  execute the following from the local-host to get the service tag of the remote-host.

C:\>wmic /user:administrator /node:remote-host bios get serialnumber

SerialNumber

ABCDEF1

[Note: Replace remote-host with the machine name of your remote-host.]

2. Get DELL Service Tag on remote Linux system

Login to the Linux remote-host using SSH. Use dmidecode on Linux to get service tag as shown below.

[remote-host]# dmidecode -s system-serial-number

ABCDEF1

Buffer Overflow Exploit in Action

Category : Internet, Microsoft

The link below shows why you should always keep your security patches up-to-date and also not click on any attachment regardless of whether it is a PDF file, a Word document or anything else from someone that you don’t know.

In the case outlined below the exploit was able to evade anti virus and malware scanners so as you can see the next best form of defense is common sense.

Beware the article is kinda technical so it might be a bit over the head of some non techy folk.
