Debugging on remote machine

[Jan Honza Odvarko]

I can't connect ndb to a node process (launched as $ node --debug
script.js) that is running on a different machine, it works only with
127.0.0.1 host. Is that known limitation or I am rather doing
something wrong?

Yeah - just use the --host option (see --help for other options like --port if you need them).

HTH,

I did use the --host option.

Here is my scenario.

1) I have ran the node process one the first machine (10.0.0.2) as
follows:
$ node --debug-brk main.js
debugger listening on port 5858

2) Consequently I ran the ndb on the second machine:
$ ./bin/ndb --host 10.0.0.2
Could not connect to host 10.0.0.2 on port 5858. Will try again in 2
seconds.
Could not connect to host 10.0.0.2 on port 5858. Will try again in 2
seconds.

Both machines in the local network and there is no firewall.

I'd do a head check to make sure that port is actually open:

nmap 10.0.0.2 -p 5858

If it *is* open, then please file a bug report:

Thanks,

I have found some more info and a solution here:

The problem is that V8 debugger thread listens only on 127.0.0.1
