Kali/Post Install
From charlesreid1
Post-install procedure for Kali:
Contents
Update Aptitude
Make sure everything is up to date before you begin:
$ sudo apt-get -y update $ sudo apt-get -y dist-upgrade
just makin sure:
$ sudo apt-get install -y vim screen tmux
and in case you wanna make a spreadsheet:
$ sudo apt-get install libreoffice
Fix SSH Keys
Fix SSH keys. First, install OpenSSH server:
$ apt-get install openssh-server
Update the SSH service to be at the default runlevel (i.e., to run on boot):
$ update-rc.d -f ssh remove $ update-rc.d -f ssh defaults
Move the old SSH keys somewhere else:
$ cd /etc/ssh/ $ mkdir insecure_original_default_kali_keys $ mv ssh_host_* insecure_original_default_kali_keys/
And finally, make new SSH keys for this machine.
$ dpkg-reconfigure openssh-server
If you want to enable root login at this point, do so:
$ vim /etc/ssh/sshd_config
add the line
PermitRootLogin yes
Set ssh to start running on all runlevels:
update-rc.d -f ssh enable 2 3 4 5
Add Non-Root User
List all users on system
Let's start by looking at what users are on the systeHOLY TOLEDO THAT IS A LOOOOOOT OF USERS
root@mars:~# cut -d: -f1 /etc/passwd root daemon bin sys sync games man lp mail news uucp proxy www-data backup list irc gnats nobody libuuid mysql messagebus colord usbmux miredo ntp Debian-exim arpwatch avahi beef-xss dradis pulse speech-dispatcher haldaemon sshd snmp iodine postgres redsocks stunnel4 statd sslh Debian-gdm rtkit saned dnsmasq
THAT IS A LOT OF USERS
List all users logged in
But only one of those many, many users is logged in:
root@mars:~# w 23:32:24 up 13:26, 2 users, load average: 0.00, 0.01, 0.05 USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT root pts/0 10.0.0.120 23:18 0.00s 0.16s 0.00s w
Add new user
Now we can add our new user:
root@mars:~# useradd -m charles
the m flag creates a home user. Check out our user's user id and group id:
root@mars:~# id charles uid=1000(charles) gid=1001(charles) groups=1001(charles)
Change user password:
root@mars:~# passwd charles
Add the user to the sudoers group:
root@mars:~# usermod -a -G sudo charles
Specify shell:
root@mars:~# chsh -s /bin/bash charles
