About This Repo

This is a simple utility that will simulate an SSH endpoint as a Ciena, Cisco, or Juniper with a very small command set.

To Run This

System prep

• Download and install Linux (here Ubuntu)
• Install docker apt-get install docker.io
• Note that to do installs and start containers, you must be root or use the sudo command prefixed to each one
• If installing Linux onto a VM, make sure the network adaptor is in the correct mode depending on use case, such as bridged if you want to SSH in from another machine than the VM host
• If you want to start the container at boot, follow this tutorial after getting the container onto your system via the "From Source" or "From DockerHub" sections below

From Source

• Download this repo somewhere (here /root/FakeTelnet)
• Change to the directory cd /root/FakeTelnet
• Build the container docker build -t gskyft .
• Start the container docker run -t -i -d -p 2222:22 --name ft gskyft
• After that, you should be able to ssh to the server on port 2222

From DockerHub

• Start the container docker run -t -i -d -p 2222:22 --name ft graboskyc/faketelnet
• After that, you should be able to ssh to the server on port 2222

Command Set

Juniper

• SSH into the device on port 2222 using username juniper and password juniper0
• Enter configuration mode (configure)
• Set root password (set system root-authentication plain-text-password newpassword)
• Hostname is customizable and when you commit, it will set the host name in the prompt
• Set hostname (set system host-name JuniperMX480-01)
• Set domain (set system domain-name example.com)
• Set default route (set system backup-router 10.0.0.1)
• Set default route (set routing-options static route default nexthop 10.0.0.1 retain noreadvertise)
• Save configuration (commit)
• Kill connection (exit)

Cisco

• SSH into the device on port 2222 using username cisco and password cisco
• Show interfaces (show ip interface brief)
• Show interfaces (show interface descriptions)
• Show terminal server hosts (show hosts)
• Enter configure mode (configure terminal)
• Add a new terminal server host (ip host ciena3916 2048 192.168.1.1)
• Exit configure mode (end)
• Save configuration (write memory)
• Enter any bad command and it will spit it back to you
• Kill connection (exit)

Ciena

• SSH into the device on port 2222 using username su and password wwp
• Create a VLAN (vlan create vlan 100)
• Note that all VLAN numbers and ports (1-6) are usable for all these commands. Also note you must create the VLAN before adding it to a port. The script does not have logic to handle this
• Add VLAN to a port (vlan add vlan 100 port 2)
• See list of VLANs on which port (vlan show)
• Show statistics with fake counters (port show port 2 statistics)
• All ports share the same fake statistics. Once cleared, they will be zero for the rest of the SSH session.
• Reset fake counter statistics (port clear port 2 statistics)
• Remove VLAN from port (vlan remove vlan 100 port 2)
• Be sure to remove the VLAN from the port before deleting. There is no logic to handle this
• Delete a VLAN (vlan delete vlan 100)
• Save configuration (configuration save)
• Enter any bad command and it will spit it back to you
• Kill connection (exit)
