How to debug WIFI connection between two Ubuntu

  • 772

I have made all steps from How to share files through the local network?

I am able to connect to my PC1, if it works as WIFI router with its built in WIFI adapter, but if I connect it to my WIFI router, it has internet.

My second PC2 are connected to the same WIFI router too and has internet.

I know IPs of both. I can not connect with sftp in both ways.

In first case it says: Oops! Something went wrong, Unhandled error message. Timed out when logging in.

The PC2 says: Unable to access location. No route to host

my PC1's IP: 192.168.0.101, and second IP 192.168.0.102

How to find out what's wrong. I am really tired of messing up with USB flash drive and copy/move files with it.

I've wasted an hour for this with no result.

Words that Ubuntu/Linux is user friendly are real bullshit.

  1. You need to tell your firewall that it should accept incoming connections from ssh and ftp. Try doing a sudo ufw allow ssh and sudo ufw allow ftp, and ask for status. (sudo ufw status)
