I use Robo 3T as a UI tool for MongoDB on a Windows 8 machine. Now I've deployed the DB to production on a Ubuntu 14 server in Amazon EC2 cloud. When I try to connect from the Windows machine to the Ubuntu one via Robo 3T, I receive the following error:
Cannot connect to the MongoDB at [http://12.345.678.90]:27017.
Error: No unix socket support on windows
Is that a problem I need to fix on my computer by installing something? or it's an issue of Mongo 3T?
If it's an issue on my Windows, what do I have to install in order to make it work?
If it's a Mongo 3T issue, do you know another UI that does support connecting from Windows to Ubuntu?
Perhaps an EC2 solution?
Or maybe some settings I need to change in Robo 3T?
I've tried changing "http" to "mongodb" to no avail. I've also tried removing the protocol prefix as suggested here but I ended up with the error:
Cannot connect to the MongoDB at 12.345.678.90:27017.
Error: Network is unreachable.
Do you have a bindIP setting in your mongo configuration file? Probably that can cause the error.
Either remove the bindIp configuration or allow your IP to access mongo server.
(restart your service after changes the configuration).

Description
I have a Node server and React App running on my notebook Ubuntu 18.04.
Notebook ip is 10.0.0.101
I tried to connect my desktop to this server on the same network
Desktop ip is 10.0.0.100
Node is running on PORT=3333
React is running on PORT=3000
I can ping my notebook from my desktop but when I try to connect to node using Insomnia or to http://10.0.0.101:3000 from my desktop I cannot reach.
Errors
When try to connect to backend with Insomnia
Error: Couldn't connect to server
When try to connect to app on 10.0.0.101:3000
ERR_CONNECTION_TIMED_OUT
What I've done
I already changed the node listen and specified the port and the ip but it didn't work.
I tried to use my phone as router and connect from my phone to react on my notebook and also didn't work.
I've tried so many things since I can't remember them all.
I'm also creating a react-native app and when I try to connect to my mobile using Expo, it just works using tunnel, but cannot get data from the backend.
Please save me.
Thanks
After making many failed attempts, I realized that the problem was in my notebook.
I checked my firewall and it was disabled and still cannot get acess to my notebook on LAN. But finally I discovered what have to be done
Solution
You have to open the specific port for TCP traffic
Ubuntu:
sudo ufw allow <PORT-NUMBER>/tcp
or for Red Hat Enterprise
firewall-cmd --add-port <PORT-NUMER>/tcp

I want to connect my apps nodejs using node-posgres to PostgreSQL. My apps in linux server and my postgresql in another linux server by 176.9.154.123 IP.
this is my error:
this is my pg_hba.conf:
host all all 176.9.154.123/32 trust
i can solve this problem by add this line to postgressql.conf:
listen_addresses = '*'
I am using MongoDB v3.6.3 on macOS, installed via home-brew. I have used almost every possible way to make my MongoDB server accessible on local network, but to no avail. I have:
Turned off firewall on both machines
Edited \etc\mongod.conf file to add bindIP.
used options-> bind_ip, bind_ip_all (127.0.0.1, 0.0.0.0, other machine's address)
As a matter of fact, also, my redis-server is not accessible on network.
I believe there is a common issue in between this.
I have tried the above mentioned solutions on macOS High Sierra, Ubuntu 16, Windows 10.
I have been facing the same error.
You could allow external access using the following parameters when starting your server:
mongod --bind_ip_all // Allow any ip
or
mongod --bind_ip <your_ip_here>
Open MongoDB config file.
Add the below command in that file(mongod.conf) and save it.
Mac config file location is : /usr/local/etc/mongod.conf
net:
bindIp: 0.0.0.0
Important Note: Once saved please restart the MongoDB services then only it will work.
Apologize in front, maybe the situation here is a bit complicated. I searched everywhere online but couldn't find a perfect solution, plus I have tried almost all the solutions mentioned in other posts.
Situation:
So I have a postgreSQL database installed in a Ubuntu system. The system is actually a virtual machine on the VMware workstation 12, which is installed on Windows 7 professional. Now I am trying to remotely access the postgreSQL database through my MacBook pro 2013.
In the Mac terminal, the command line I tried is:
psql -U postgres -h xxx.xxx.xxx.xx
"xxx.xxx.xxx.xx" represents the IP address of the Windows 7 machine. The result is a failure:
psql: could not connect to server: Operation timed out
Is the server running on host "169.254.121.2" and accepting
TCP/IP connections on port 5432?
What I have done:
Edited the pg_hba.conf file to include
host all all 0.0.0.0/0 md5
Edited the postgresql.conf to include
listen_addresses='*'
Restarted postgres service.
Disabled firewall on the host.
I checked by running the psql command locally and it worked. Also, on the same VMware I have other Ubuntu systems. They are all fine to connect and access the data in this Ubuntu system.
Running Nmap, the output is
PORT STATE SERVICE
5432/TCP open postgresql
What's next? Anything else I can try? Any advice is highly appreciated and please let me know if anything above is ambiguous. I will clarify for better diagnosis. Thank you all!
Somehow managed to get it working..
So when I ran "Nmap" on the other Ubuntu system towards this one, it does shows
PORT STATE SERVICE
5432/TCP open postgresql
However, when I ran "Nmap" on my Mac, it's a different port, 3389, which is mainly used for Windows remote desktop. So what I did was to check the network configuration of this Ubuntu virtual machine from "bridged" to "NAT" and did a port forwarding to 5432. It is working fine now..
I read in some places saying that VMware favors bridged whereas VirtualBox favors NAT+port forwarding. I am quite confused as it is certain not the case in my situation. Maybe I am wrong.
I have MongoDB 3.2 installed on my Linux Red Hat server.
I am starting to access it and looking at the mongo Shell instructions.
For a Windows machine, the instructions want me to get to the command prompt and change dirs to the installation directory. The problem is, MongoDB is installed on my web server and not my local windows machine.
Question: does Mongo Shell apply to me then? How do I start using, connecting and accessing Mongo from my Windows and Mac machines?
[Note: I am a traditional MySQL / phpMyAdmin developer looking to advance to MongoDB]
Amendments:
(1) With the help of #AlexBlex I am progressing to trying to connect to my MongoDB on my server from Robomongo on my windows client. I get the following error when trying to setup my connection. I tried the address with just my server ip and with http://{my server ip}. Neither worked. See screen shot of error
(2) This is what I have in my current mongod.conf file:
#port=27017
bind_ip=127.0.0.1
(3) here is what my connection settings look like. Oddly, #AlexBlex's solution below shows an SSH tab on his Mac version. The Windows and Mac versions I just installed lacks that tab.
If you install MongoDB on your local machine, you can use the Mongo shell like below to connect to your remote server
mongo yourserver:27017/database
You will have to configure your Mongo server to allow remote connections. In order to achieve this you need to have the following line in your /etc/mongodb.conf file. You need to replace 10.0.0.2 with the ip address of your client machine.
bind_ip = 127.0.0.1,10.0.0.2
You need either ssh to the server where mongodb is installed, or install mongodb on local machine.
For robomongo to connect to remote host you need to ssh to the server, and check it listens on external interface:
lsof -i | grep 27017
In case it is bound to localhost only, you need to edit a line with bind_ip in /etc/mongodb.conf and restart the service.
I would recommend to keep it listening on the local interface only for security reasons, and use ssh tunnelling to connect:
I found the answer. #ShahNewasKhan is brilliant. See How to connect Robomongo to MongoDB
All you need to do is SSH to server and edit mongod.conf file:
uncomment #port=27017 to port=27017
comment bind_ip=127.0.0.1 to #bind_ip=127.0.0.1
restart mongodb via service mongod restart
Then create a mongo connection via your server ip in the address field and 27017 in the port field
Hope this helps mongo newbies and start-ups like me :) Good luck.
Now I just need to figure out how to make this secure. My concern is that anyone who knows my server ip can hack into my MongoDB
