Windows 10: Password Less SSH between postgres and barman users in WSL2 - Not Working

HelloI have Installed Windows Subsystem for Linux on a windows 10 Pro machine. I have installed two software packages in itPostgreSQL database packages for which "postgres" is the user 2Barman Packages for which "barman" is the user.I'm trying to establish "password less SSH authentication" between the "postgres" and "barman" users within WSL2 on my Windows 10 Pro machine. I've followed these steps:Generated SSH keys 4096 bits for both users using ssh-keygen -t rsa -b 4096.Copied the public key of "postgres" to the authorized_keys file of the "barman" user at /var/lib/barman/.ssh/authorized

Weird SSH issue with WSL2 (and WSL1)

Hello all,

So this is something that has been bugging me for a while now.

I have this situation where I connect using SSH: My_Computer --SSH-> ServerA --SSH-> ServerB

The connection to ServerA is done with public key auth, and the connection from ServerA to ServerB is regular username/password.

For some strange reason, whenever I use WSL2 with an Ubuntu image (the default over the Windows Store), I never get to connect to ServerB. I successfully connect from my computer to ServerA with my key and from there the moment I input "ssh username@serverB"
I immediately get the error "ssh_exchange_identification: Connection closed by remote host", like instantly, which is very weird, as I assume the segment ServerA -> ServerB doesn't have much to do with WSL2, especially since the first connection from my computer
(running WSL2) to ServerA works perfectly fine.

I can replicate this issue on several computers and always with WSL (1 and 2).

Using any other solution, like Putty, SolarPutty, SnowflakeSSH, actual Ubuntu VM using Hyper-V/Virtualbox/VMWare works perfectly fine all the way up to ServerB.

Can anyone shed any light into this?

Thanks.

 

Setting up SSH in WSL2

Hey there! I have been using Ubuntu 20.04 on WSL2. I have successfully installed SSH in it, but while trying to connect with my IP Address, it shows the error "ssh: connect to host <IP Address> port 22: connection refused". I have already tested the same
installation procedure in Ubuntu 20.04 and it worked great. What is wrong with WSL or WSL2? Please help!
