Cisco NSO No login prompt

[zyko]

Hello

I have installed cisco nso 6.1 and created devices using ncs-netsim as below:

#configure authgroup

ncs_cli -C -u admin
conf
devices authgroups group labtest
default-map remote-name cisco
default-map remote-password cisco
default-map remote-secondary-password cisco
commit
end

#add device using ncs-netsim

ncs-netsim add-device cisco-ios-cli-3.8 rtr08
cd netsim
ncs-netsim start rtr08
ncs-netsim is-alive

#configure device on nso

ncs_cli -C -u admin
conf
devices device rtr08
address 127.0.0.1 port 10026
authgroup labtest
device-type cli ned-id cisco-ios-cli-3.8
device-type cli protocol telnet
ssh host-key-verification none
commit
state admin-state unlocked
commit
end

I am getting the below response when trying to connect to the configured router either through CLI or through the webui:

admin@ncs(config-device-rtr08)# connect
result false
info Failed to connect to device rtr08: connection refused: No login prompt

Any idea of what I am doing wrong?

Thanks

You should use ssh, not telnet. Netsim does not support telnet access.

We have several examples on how to setup netsim and NSO. Take a look at this Learning Lab - https://developer.cisco.com/learning/labs/learn-nso-with-netsim/

On the first step "Setting up NSO", you can see how to mix ncs-netsim with ncs-setup to automatically add your devices to NSO.
