I am trying to use PuTTy ssh into my ubuntu machine which is wirelessly connected to the same network. I originally ran ifconfig to get my ubuntu machines private network IP address. I then verified that ssh was running, I even ssh'd into my school network and then into the ubuntu machine itself. No problems yet.
On my windows 8 machine I ran ipconfig to get my private network IPv4 address. I then pinged my ubunty machines IP and 100% of packets were received. I figured, "OK we are ready to use PuTTy to connect to my Ubuntu Machine". Keep in mind this was my first time using PuTTy. I tried entering the IP of my ubuntu machine in the PuTTy Config GUI but I got a connection timeout. At this moment I don't really know what's going on, SSH is running on port 22 of my Ubuntu machine and I can ping the machine why is it not connecting? (I tried [username]@ip too).
So I went on my Ubuntu machine and ran nmap -sP 192.168.0.1/24 and found that my windows machines IP did not show up, the host is down. I'm at a lost in something I am not very familiar with. Would anyone be able to help me or direct me to some resources that would trouble shoot my problem?
Thank you
