Linux Ubuntu (22.04+)

1. Download installer wget https://nvisnet.com/dist/nvis_ubuntu_inst

2. Run installer chmod 755 ./nvis_ubuntu_inst sudo ./nvis_ubuntu_inst install

3. Use the address assigned to you by your Admin to obtain an NVIS IP sudo nvis -ga <insert address>

4. Verify status and addresses associated nvis -s

5. Turn NVIS ON nvis on

Verify connections

1. You can ping yourself ping <NVIS IP>

2. If connected to the test network (tlcnet), ping the test node ping 10.0.1.65

Troubleshooting

1. If ping fails, run: sudo /opt/local/nvis/bin/nvis_ubuntu_inst refresh

2. Check interface. Expect tun0 to show NVIS IP.

   sudo nvis off sudo nvis on ifconfig tun0

3. Deeper troubleshooting to disable firewall sudo systemctl stop ufw sudo /opt/local/nvis/bin/nvis_ubuntu_inst refresh

Linux (21.04 or below)

This describes how to install NVIS v7.08 for Linux 20.04 and ping a host in Paris. This shows multiple machines that can connect to each other over layer 2 encrypted in a shared group security context. You may then do whatever generators you wish to provide traffic to monitor between the NVIS IPs.

Given two computers, HOST1 connected to the Internet. I have pre-provisioned two addresses.

Address1: 0x54ef7d105246e3f3bb8b0b9e1177e41af2585102 (or your assigned address)

Here is the Linux tarball:

If it is 20.04 or later:

wget https://nvisnet.com/dist/nvis_linux_dist.tgz

INSTALLATION

On HOST1 , you will install NVIS, turn it on and check it’s status. Note that after installation, you should have the installation folder in your path. In case not, I’ll add commands to go to the installed folder

On HOST1

SSH to the host, cd to the folder with the installer, and issue:

# tar zxvPf ../nvis_linux_dist.tgz

/bin/nvis

/bin/edge

./README

# nvis

wallet address : 0x54ef7d105246e3f3bb8b0b9e1177e41af2585102

# nvis -s

10.0.3.103

# nvis -v

Nvis for Linux Version 1.2

# nvis on

Make sure the status is eventually ON.
