I have home laptop on 3G - client
I have sisters laptop on Wi-Fi router - target
I have dedicated server - middle
All on Ubuntu
I created tunnel from target to middle
Then I connect to middle from client
ssh -R 7778:localhost:22 middleuser@middleIP
And from it to target
But here I receive this errror: Permission denied, please try again.
ssh targetuser@localhost -p 7778
I actually already have success connections today, but then I broke smth...
Please help where to look first?
