Unable to SSH using Bash on WSL

Question

I have recently installed Bash on Windows thru WSL.

However, when I tried to access my school server using SSH for my projects (as I normally would using PuTTY), I keep getting the following error message whenever I tried to SSH into my school network:

The command I entered was:

ssh [email protected]

And the error message I received was:

Could not resolve hostname schooldomain.edu.com: Temporary failure in name resolution

As I am rather new to unix system, I might have missed out certain configuration steps. That said, I could access my school's server using PuTTY. Please advice if there are any other configurations that I might have to do to get it working.

Thanks folks!

can you ping schooldomain.edu.com? Does schooldomain.edu.com exist? — ifconfig

Nope. I am unable to ping schooldomain.edu.com. The return was unknown host. — xhxh96

Sounds like DNS issue. Make sure that you are able to ping schooldomain.edu.com as @ifconfig mentioned in the comment. Also make sure that you have the correct DNS entry in /etc/resolv.conf. It should look similar to

cat /etc/resolv.conf
nameserver 8.8.8.8
nameserver 8.8.4.4

I am using google DNS but you can use any DNS you want.

Hi, Thanks for the reply. However, I am unable to ping to schooldomain.edu.com. I get ping: unknown host schooldomain.edu.com I managed to get reply when I executed the ping command on my cmd (outside the unix environment) though. I have made changes to my resolv.conf like you mentioned but it still doesn't work.

Can you get access to the site using Windows on the same host? If so, did you have to make any Windows-specific configuration changes to do so?

Turns out that it was because AVG’s firewall blocks all WSL processes by default. Got it working finally. Thanks folks!
