Gulpfile, Rsync,RsyncWrapper, Rsync Exits with code 12 - vagrant

Question

Im trying to use gulp to handle my rysnc task from a local dev environment to a running vagrant machine.
The gulp task is set up like this:
var rsync = require('rsyncwrapper').rsync;
var secrets = require('./secrets.json');
// ###Rsync
// Ran from gulp
gulp.task('deploy', function() {
rsync({
ssh: true,
src: './website/',
dest: secrets.servers.dev.rsyncDest,
recursive: true,
syncDest: true,
exclude: ['node_modules'],
args: ['--verbose'],
privateKey: './.vagrant/machines/default/virtualbox/private_key',
onStdout: function (data) {
console .log (data.toString ());
}
},function (error,stdout,stderr,cmd) {
if ( error ) {
// failed
console.log(error.message);
} else {
// success
console.log("folder synced!");
}
});
});
The secrets.json contains the path to my destination vagrant machine:
{
"servers": {
"dev": {
"rsyncDest": "vagrant#192.168.2.101:/opt/webiste"
}
}
}
The rest of my gulp file works without issue, a normal vagrant rsync also works to transfer the file across.
However, when I run my task deploy, I simply get: Rsync Exited with code 12.
After some googling I found that this means the protocol stream has failed but I am unsure as even where to begin trying to fix this issue.
Any help would be greatly appreciated!

Answer 1

I encountered the same problem. It occurred when I destroyed and rebuilt my vagrant machine, but I left the old key in ~/.ssh/known_hosts file. The error message gulp-rsync isn't helpful. If you try to login directly you'll get an error like this:
>> ssh vagrant#192.168.50.104
###########################################################
# WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! #
###########################################################
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
87:9b:39:02:b8:96:6b:21:01:fa:b5:42:5f:0a:0b:f7.
Please contact your system administrator.
Add correct host key in /Users/me/.ssh/known_hosts to get rid of this message.
Offending RSA key in /Users/me/.ssh/known_hosts:36
RSA host key for 192.168.50.104 has changed and you have requested strict checking.
Host key verification failed.
To fix it, edit the file ~/.ssh/known_hosts. Remove the line for the host key of your vagrant machine. In my case, it was line beginning with 192.158.50.104.
The next time you run gulp-rsync, you'll have to type yes at the prompt.
