mongodump dose not work on remote host

[Zhen Cao]

hi,

i use command mongodump to backup mongodb instance:

mongodump -h 192.168.150.101 --username ira.cao --password ira.cao -d udisk -o temp

its output:

connected to: 192.168.150.101

2018-03-01T11:52:34.035+0800 DATABASE: udisk to temp/udisk

but temp/udisk is a empty dir

run the same command on host 192.168.150.101, it works well locally

its output:

Hi

Did you see any error message? Could you try running mongodump with the --verbose option and see if there’s any error message? Please also post the complete output of the remote mongodump command.

It will also be helpful if you can provide your exact MongoDB version (e.g. 3.6.3) along with some relevant information about your deployment (e.g. is it a replica set, is it MongoDB Atlas, what OS are you using, etc.)

Best regards
Kevin
