I have Ubuntu installed on one of my laptops with the GUI disabled. I installed
openssh-server and tried accessing it from PuTTY from my Windows machine and it was working all fine. Later I had to switch WiFi networks on both Windows and Ubuntu. Switching in Windows was easy but with Ubuntu it took me some time. Now I have both the systems connected to the same network over WiFi. Even the Internet is accessible from the Ubuntu machine using elinks but ssh is not connecting from the Windows machine. Tried reinstalling but no luck. Please help.
Even I am unable to ping the Linux machine from my Windows PC. I tried
ifconfig -a and got IP address 192.168.0.107 for wlan0. This is visible in the below screenshot:
I also have Apache on 80 and Tomcat on 8080, but neither is accessible from the LAN, only from within the same PC.
