Tried taking dump from a remote node and got the following error:
Failed: can't create session: could not connect to server: connection(): auth error: sasl conversation error: unable to authenticate using mechanism "SCRAM-SHA-256": (AuthenticationFailed) Authentication failed.
Tried two methods to take dump from the remote node. But got the same error in both the methods.
# Method 1
mongodump -h remoteip@port -u xxx -p xxx --db xxx --authenticationDatabase xxx
# Method 2
mongodump --uri "mongodb://username:password@remoteip:port/db?authSource=xxx"
How to resolve this?
回答1:
I had the same issue. In my case, the password has special characters. It works with single quote for password:
-p 'my_password'
回答2:
I had the same problem and solved it using single quotes in the password like this:
--password 'secret'

Was in the same spot that you are, solved it this way:
mongodump --uri "mongodb+srv://username:password@yourmongodbclustersourceurl" --archive \
mongorestore --uri "mongodb+srv://username:password@yourmongodbclusterdestinationurl" --archive \
--nsExclude "admin.system.*"
Needless to mention, you just need to change your username, password and the url in this formula and voila. Good luck.

For me (trying to use mongodump on a single node DB on the same host), using --authenticationDatabase admin did the trick:
mongodump -u root --password 'secret' --authenticationDatabase admin -d mongo-dev -o /tmp/dump-2020-11-27.bson
