NSO - Problem creating a NETSIM device

humbertomoya96676 — Wed, 25 Sep 2019 21:05:33 GMT

i finish install my NSO 5.1 on ubuntu.

i try to create a device in NETSIM and i get this error:

same thing happened to me. I did the "source $HOME/nso-5.1/ncsrc" command again, even though I didn't think I needed to since I'd already done it......voila.

You need to point to the NED package location.

If your NED is in ./packages/cisco-ios-cli-3.8, then the line should be:

ncs-netsim create-device packages/cisco-ios-cli-3.8 CE0

otherwise, ncs-netsim is looking for the NED under the current directory, which is usually not the case (you don't create netsim devices inside your packages directory).

Going off this error message:

mat@mat-VirtualBox:~$ ncs-netsim create-device nso-5.3/packages/neds/cisco-ios-cli-3.0 mydevice
env: «make»: Aucun fichier ou dossier de ce type

I took a quick look at the ncs-netsim script (ncs-5.3/bin/ncs-netsim) looking for a a potential issue with 'make' on an 'env' command:

I found this:

if missing_cmd gmake; then
MAKE=make
else
MAKE=gmake
fi

<..snip..>

env DEST_DIR="${destdir}" NAME=${rname} COUNTER=${rno} \
TWO_DIGIT_COUNTER=${counter} ${MAKE} -s install

If gmake is not available it will default to make...

If make is not available will cause and error in this env command.

I'd guess that make (or lack of) on your ubuntu system may be the cultprit.

Its lacks OS components. For ubuntu 20, you need to install "build-essential" as the example below:

nso5@nso5:~/nso-run$ ncs-netsim create-network packages/cisco-iosxr-cli-3.5/ 3 XR

env: ‘make’: No such file or directory

*** Failed to install

Try ncs-netsim --help or man ncs-netsim to get usage text

nso5@nso5:~/nso-run$ sudo apt install build-essential

This is what we run when creating images on ubuntu-latest (container stuff but applicable to your situation too).

apt install python3 python3-pip libxml2-utils curl make ant xsltproc

What exactly is or is not in ubuntu-latest compared to image you used to spin up your VM, is a different matter. If you used anything "fatter" than Ubuntu Minimal Cloud Image, not much else should be missing.

I had the same issue with the docker implementation:

ncs-netsim create-network /nso/run/packages/cisco-ios-6.92 2 ios, see bellow message:

*** The NED package called </nso/run/packages/cisco-ios-6.92> doesn't have a
*** netsim directory. ncs-netsim cannot emulate
*** devices that do not have a netsim directory.
Try ncs-netsim --help or man ncs-netsim to get usage text

In my case what solved it was to specify the path + full name for the package:

ncs-netsim create-network /nso/run/packages/ncs-6.1-cisco-ios-6.92.8.tar.gz 2 ios
DEVICE ios0 CREATED
DEVICE ios1 CREATED
