SSH From Windows Command Prompt

The title says it all. I had this question from one of my buddies earlier today. First, you'll need PuTTY installed in the Windows machine.

If we navigate to PuTTY directory, we are able to see there is a piece of executable called plink.exe. This would enable you to SSH directly to any devices (of course the ones that support SSH) from Windows command prompt.

The executable is invoked for SSH to target devices using the below syntax example:

Hope this helps for command line peoples out there!

Getting Notepad++ Installed In Your Linux Distribution

When dealing with scripts, you'll need a better text editor to work on the fly. I've been using Windows previously, and Notepad++ is a good text editor to get me going around scripts. Moving recently to Linux, you can't get Notepad++, but you may use Notepadqq as an alternative.

Here are the steps to install this piece of text editor. First, add the required repo to get the installer:

root@ubuntu:/home/fwnh67# add-apt-repository ppa:notepadqq-team/notepadqq
 Notepadqq text editor
 More info: https://launchpad.net/~notepadqq-team/+archive/ubuntu/notepadqq
Press [ENTER] to continue or ctrl-c to cancel adding it

gpg: keyring `/tmp/tmpgrega6w7/secring.gpg' created
gpg: keyring `/tmp/tmpgrega6w7/pubring.gpg' created
gpg: requesting key 63DE9CD4 from hkp server keyserver.ubuntu.com
gpg: /tmp/tmpgrega6w7/trustdb.gpg: trustdb created
gpg: key 63DE9CD4: public key "Launchpad PPA for Notepadqq Team" imported
gpg: Total number processed: 1
gpg:               imported: 1  (RSA: 1)
OK

Once the repo has been added, update the repo lists.

root@ubuntu:/home/fwnh67# apt-get update

After that, fetch the installer and installed the software.

root@ubuntu:/home/fwnh67# apt-get install notepadqq

Installing GIT On CentOS5

A simple sharing today, seems that installing git on CentOS5 (I am using CentOS 5.8 for some testing) requires different steps rather than the Ubuntu distribution I used previously.

First, you got to install some git dependencies:

[root@localhost ~]# yum -y install zlib-devel openssl-devel cpio expat-devel gettext-devel

Complete!

Next, we need to change the directory to source directory:

[root@localhost ~]# cd /usr/local/src

And then proceed to download git.

[root@localhost ~]# wget https://git-core.googlecode.com/files/git-1.9.0.tar.gz

After the download is done, extract the tar package.

[root@localhost ~]# tar xvzf git-1.9.0.tar.gz

Change the working directory to:

[root@localhost src]# cd git-1.9.0

Once done, invoke the below commands one by one (always wait for each to finish the tasks first):

[root@localhost ~]# ./configure
[root@localhost ~]# make
[root@localhost ~]# make install

And you're done! :O)

Getting Speedtest Into Your CLI

Previously, I performed Internet bandwidth and speedtest using GUI, browser and etc. However, since some of us might love terminals more (yes...it is indeed faster!), I'm going to share on how can we install speedtest script to our host OS.

The distribution that I used in this post would be:

root@ubuntu:/home/fwnh67# lsb_release -a
No LSB modules are available.
Distributor ID:    Ubuntu
Description:    Ubuntu 14.04.3 LTS
Release:    14.04
Codename:    trusty

Ah, before I forget, you got to elevate the terminal privilege to root before installing the speedtest-cli script.

Moving on, we invoke the below command to get the script installed:

root@ubuntu:/home/fwnh67# pip install speedtest-cli
Downloading/unpacking speedtest-cli
Downloading speedtest_cli-0.3.4-py2.py3-none-any.whl
Installing collected packages: speedtest-cli
Successfully installed speedtest-cli
Cleaning up...

Once done, you may return back to your original user privilege.

From the terminal, get speedtest to run and get your internet speed tested. Example as per below:

fwnh67@ubuntu:~$ speedtest
Retrieving speedtest.net configuration...
Retrieving speedtest.net server list...
Testing from TiME (1.1.36.4)...

Your Credentials Did Not Work!

Well, a classic solution to a classic problem.

Click on Start button, and search for gpedit.msc. Open.

In Computer Configuration, expand Administrative Templates.

Expand System.

Expand Credentials Delegation.

Double click Allow Delegating Saved Credentials and enable this.

Under add servers, I'm placing a wildcard just to allow every servers that I wanted the password remembered.

Click OK and then Apply.

Repeat the same with Allow Delegating Saved Credentials with NTLM-only Server!

Installing Firefox In Kali Linux

Ok, the next problem that I am facing right now is with the absence of a web browser for some surfing.

Here are the steps to download and install Firefox in your Kali Linux box:

Use the wget command to fetch the tar file from Firefox official site. Example:

xox@XOX-KLINUX:~$ wget https://download-installer.cdn.mozilla.net/pub/firefox/releases/40.0.3/linux-x86_64/en-US/firefox-40.0.3.tar.bz2
--2015-08-29 02:28:50--  https://download-installer.cdn.mozilla.net/pub/firefox/releases/40.0.3/linux-x86_64/en-US/firefox-40.0.3.tar.bz2

Unzip the tar file into the /usr/local directory, make sure you run this as root!:

root@XOX-KLINUX:/home/xox# ls
Desktop  Documents  Downloads  firefox-40.0.3.tar.bz2  Music  Pictures  Public  Templates  Videos
root@XOX-KLINUX:/home/xox# cd /usr/local
root@XOX-KLINUX:/usr/local# tar xjf /home/xox/firefox-40.0.3.tar.bz2
root@XOX-KLINUX:/usr/local# ls
bin  etc  firefox  games  include  lib  man  sbin  share  src

And you're done!

Adding Users In Kali Linux

For my work purpose, I need to use Kali Linux now. Been experimenting with it a little bit, I applied my experience to add user within the OS but it seems not to go through at all.

Had quite a hard time and around half an hour spent thinking on the solution, here are the steps for the unfortunate :P

First, by default, you should be logging into Kali Linux as a root user. I am using Kali with the below version output:

root@XOX-LINUX:~# uname -a
Linux XOX-LINUX 4.0.0-kali1-amd64 #1 SMP Debian 4.0.4-1+kali2 (2015-06-03) x86_64 GNU/Linux

root@XOX-LINUX:~# lsb_release -a
No LSB modules are available.
Distributor ID: Kali
Description: Kali GNU/Linux 2.0
Release: 2.0
Codename: sana

And here are the steps for new user creation:

root@XOX-LINUX:~# adduser xoxuser
Adding user `xoxuser' ...
Adding new group `xoxuser' (1001) ...
Adding new user `xoxuser' (1000) with group `xoxuser' ...
Creating home directory `/home/xoxuser' ...
Copying files from `/etc/skel' ...
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
Changing the user information for xoxuser
Enter the new value, or press ENTER for the default
Full Name []: Bob Nuxi
Room Number []:
Work Phone []:
Home Phone []:
Other []:
Is the information correct? [Y/n] y

Verification of new user:

root@XOX-LINUX:/etc# cat passwd | grep xoxuser
xoxuser:x:1000:1001:Bob Nuxi,,,:/home/xoxuser:/bin/bash

I'll edit this posting if any future changes are seen, but for now, hope it helps!
