Ubuntu how to setup a vpn connection, tsocks, corporate wifi with openconnect and openvpn or socks

These are just notes.

Cisco vpn setup [corporate setup]


# install
sudo apt-get install openconnect network-manager-openconnect-gnome

VPN GUI setup
# select dynamic updates
sudo dpkg-reconfigure resolvconf


#restart network-manager or reboot the laptop


#  create a new VPN openconnect connection, set only the gateway
nm-connection-editor

Gnome network manager GUI configuration

[This is not needed for Ubuntu 15.04 and 16.10]. The default routing rules are missing in ubuntu openconnect 15.10/16.04. After the network manager establishes the connection, the work around is to add a default route as specified below after the connection is established. Start a console and type the command below with the correct arguments.

sudo route add default netmask 255.255.255.0 gw 10.87.154.223 dev vpn0

run ifconfig to figure out the vpn device name, the gateway ip of the vpn device normally tun0 or vpn0.

Execute the command above and the default route should make the openconnect vpn work.

Command line without network manager

# open a connection, use --background to run as daemon
sudo openconnect --user=USERID server/group/

# to stop the connection you can ctrl-c the terminal running openconnect or

sudo killall openconnect*

Setup openvpn using ibvpn.com provider and openvpn

sudo apt-get install openvpn easy-rsa network-manager-openvpn-gnome

goto http://www.ibvpn.com

setup a free account

extract openvpn.tgz where you want

On UbuntuGnome goto settings->network->add
select vpn->Import from file

Select ibVPN-US-Dallas.ovpn


Type your email
Get the password from the ibvpn website, this is not you ibvpn account password.




Select Add.
And try it out.

Using  a socks proxy instead of VPN


# run a local socks server
ssh -D 9999 proxy.server

# setweb browser proxy or gnome network proxy in gnome network settings.
proxy: localhost:9999

# To use other apps with socks install
sudo apt-get install tsocks

# Change config file to (remove everything else)
/etc/tsocks.conf
server = 127.0.0.1
server_port = 9999

# ssh to a machine
tsocks ssh -X bla.corp.com

# eclipse to a machine
tsocks eclipse

See my previous post on how to install Ubuntu on Yoga Pro 2 for Ubuntu GNOME 16.10.

I think Ubuntu GNOME is the best flavor of Ubuntu if you are running in HiDPI mode 3200x1800. All screen captured images are at HiDPI resolution.
Touch support Ubuntu gnome support for touch screen is pretty good on the desktop shell.
Chrome browser supports touch screen very well and much better than Firefox without any plug-ins.
The windows key on the screen panel works as the windows key on the keyboard.
Screen rotation is supported on the new gnome and disables the keyboard when the yoga is used as a tablet, side lock rotation button works to lock the screen in a certain rotation.

Ubuntu GNOME 17.10

I think Ubuntu GNOME is the best flavor of Ubuntu if you are running in HiDPI mode 3200x1800 with a touchscreen. All screen captured images are at HiDPI resolution.

Since I prefer the standard gnome-session experience, I installed the "gnome-session" package and rebooted the system. And on the cog icon next to the sign in button, select the "GNOME" instead of ''Ubuntu" option before clicking the sign in button.

sudo apt install gnome-session

Touchpad
I increased the speed, enabled "tap to click", "two finger scrooling". and on gnome-tweak enabled click method to "fingers".
Touch support Ubuntu gnome support for touchscreen is pretty good on the desktop.
Chromium browser supports touch screen very well and much better than Firefox without any plug-ins.

Using a socks proxy

#ssh to a machine on the network you need access and start # a local socks server ssh -D 9999 httpserver.blah.com
# setweb browser proxy to proxy: localhost:9999
# To use other apps with socks install sudo apt-get install tsocks
# Change config file to (remove everything else) /etc/tsocks.conf server = 127.0.0.1 server_port = 9999
# ssh to a machine tsocks ssh -X httpserver.blah.com
# eclipse to a machine tsocks eclipse
