I have a host running Windows 10, WSL 2. My guest is Ubuntu.
I'm trying to use sqlcmd
to connect to the SQL Server running on my host machine, but I'm not sure what IP to use in the connection?
I've exposed/enabled basically everything from the SQL Configuration Manager on the host Windows SQL Server, and am using commands like this to try to connect:
sqlcmd -S 127.0.0.1 -U sa -P pass
Sqlcmd: Error: Microsoft ODBC Driver 17 for SQL Server : Login timeout expired.
Have you try looking on the IP on /etc/resolv.conf?
Try connecting using that one, example: sqlcmd -S 192.168.202.65 -U sa -P pass
This is because of this
You also have to open the 1433
port in Windows Firewall.
New rule - Port - Next - Specific ports 1433 - Next - Allow - Next - Next - Name "WSL2 sql"
IMPORTANT: now edit the rule again (otherwise you just opened the port to the entire world!) and limit it to your WSL2 IP address only.
Double click the rule - Scope - Remote IP ads - Add WSL2 address
To find your wsl host address type wsl hostname -I
in windows cmd shell.
Enabling the "Virtual Machine Monitoring" worked for me. These four firewall rules are located in the inbound list, names starting with "Virtual Machine Monitoring" for:
They appear to be disabled by default and once I enabled them, I was able to ping the host as well connect to my host sql server service using the IP address from the WSL generated resolv.conf file --
cat /etc/resolv.conf
# This file was automatically generated by WSL. To stop automatic generation of this file, add the following entry to /etc/wsl.conf:
# [network]
# generateResolvConf = false
nameserver 1xx.1xx.1xx.1xx
