If you are using a SNAPstick 200 or SN220 SNAPstick, SNAPtoolbelt can scan for your node(s):
$ snap config scan
SNAPtoolbelt will automagically add new nodes (including sniffer nodes) to your configuration.
If you get a message about a
Read error, you can bypass it by adding the
--force flag. Read errors
may just mean (a) this node’s actually a SNAP Sniffer, we were looking for non-Sniffer nodes, or (b) it was busy
when we tried to talk to it.
To make one of them your default, move it to the default profile:
$ snap config move profile SNAPstick0 default
