I've recently set up a Ubuntu 16.04 desktop, and installed openSSH. I can access this desktop via SSH from my Ubuntu 16.04 laptop, but not from Windows 10 PuTTY. I get no response when I tried to ping from Windows either. However, I can connect to other servers via SSH from Windows. I'm a bit confused and not sure where the problem is. The error I get from putty is Network Connection Time Out. Any tips will be appreciated, thanks!
