NSO getting started guide examples errors

smolz — Wed, 19 Dec 2018 22:54:43 GMT

Trying to run through the getting starting guide and getting errors on the first example when doing a `devices connect`

admin@ncs# devices connect

connect-result {

device c0

result false

info Failed to connect to device c0: connection refused: Connection refused (Connection refused)

}

connect-result {

device c1

result false

info Failed to connect to device c1: connection refused: Connection refused (Connection refused)

}

connect-result {

device c2

result false

info Failed to connect to device c2: connection refused: Connection refused (Connection refused)

}

admin@ncs# *** ALARM connection-failure: Failed to connect to device c0: connection refused: Connection refused (Connection refused)

admin@ncs# *** ALARM connection-failure: Failed to connect to device c2: connection refused: Connection refused (Connection refused)

admin@ncs# *** ALARM connection-failure: Failed to connect to device c1: connection refused: Connection refused (Connection refused)

Hi,

I assume these are netsim devices.

Did you go to the requested directory and perform the desired steps?

Go to examples.ncs/getting-started/using-ncs/1-simulated-cisco-ios. ### In the install directory, follow the requested path

$ ncs-netsim create-network $NCS_DIR/packages/neds/cisco-ios 3 c

then perform the:

ncs-netsim start ## starts the 3 created netsim devices

And try to connect to the generated netsim devices.

Where exactly did you stop in the documentation?

$ ncs-setup --netsim-dir ./netsim --dest .## must be defined as well.

I just played with the same example and I get the same response as you if I stop my netsim devcies and then try to re-connect.

try "ncs-netsim status" and see if they are started.

i.e.

connect-result {

device c2

result false

info Failed to connect to device c2: connection refused: Connection refused

}

[ok][2018-12-20 10:27:32]

admin@ncs> *** ALARM connection-failure: Failed to connect to device c1: connection refused: Connection refused

:~/nso-4.7/examples.ncs/getting-started/using-ncs/1-simulated-cisco-ios$ ncs-netsim status

DEVICE c0

connection refused (status)

DEVICE c1

connection refused (status)

DEVICE c2

connection refused (status)

I have tried on both Mac and Ubuntu. See the 2 sections below

On mac:

Re: NSO getting started guide examples errors

Hi, so i think i know what the issue is/was.

Josephs-MacBook-Pro:1-simulated-cisco-ios jleepak$ ncs-setup --netsim-dir ./netsim --dest .
Using netsim dir ./netsim

I stopped NSO due to my previous instance being up via ncs --stop. Started NSO

Josephs-MacBook-Pro:1-simulated-cisco-ios jleepak$ ncs
Josephs-MacBook-Pro:1-simulated-cisco-ios jleepak$ ncs_cli -C -u admin

admin connected from 127.0.0.1 using console on Josephs-MacBook-Pro.local

}

What I think you did was forgetting to set up the netsim-dir in the examples.ncs/getting-started/using-ncs/1-simulated-cisco-ios directory.

You must remain in the directory of the desired samples.

tperiasa — Mon, 11 Feb 2019 01:22:33 GMT

Not true. I did follow the examples. set the netsim folder to the examples folder.

I got the same error , connection refused.

Can you show me step by step how you are performing this? Can you perform 'pwd' and proceed with trying to generate the samples?

I see this in your status:

DEVICE c0
./env.sh: line 12: export: `Fusion.app/Contents/Public:/Library/TeX/texbin:/opt/X11/bin:/Library/Frameworks/Mono.framework/Versions/Current/Commands:/usr/local/bin:/Users/smolz/bin:/Users/smolz/.rvm/bin:/Users/smolz/.rvm/bin': not a valid identifier
vsn: 6.7

I'm not sure if that affects the netsim, but i notice i do not have that in my status output. What device are you trying to run the samples on?
