unable to run the l3VPN services example on the NSO user guide

[kerim mohammed]

Hi,

I don't seem to be able to run one of the examples provided on the user guide because of the following error when running "make stop clean all start" :

root@localhost mpls-vpn]# make stop clean all start

ncs-netsim stop

*** Need to either specify a netsim directory with --dir or be able

*** to find a netsim directory above us in the directory hierarchy

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

make: [stop] Error 1 (ignored)

ncs --stop

connection refused (stop)

make: [stop] Error 1 (ignored)

Hi,

"/bin/sh: ant: command not found"

You need to install ant

Ubuntu ex:

sudo apt-get install ant

Make sure you also have JDK installed

br,

Hi,

Make sure you source the ncsrc file in the NSO installation directory.

ex:

source /home/kerim/ncs_install/ncsrc

ncsrc has the paths to all the nso libs and binaries.

[kerim mohammed]

I sourced it. In fact, I installed jdk1.9 and set the environment variables (PATH). did new installation of ncs. but still...

able to give further configuration.
