ANSWERED SSH "Socket bind failed on local address"

Recommended Posts

Guest MuYiXiao

Running Fedora 21, KDE

I'm in china

 

Trying to connect via SSH.  I tried all 4 port options listed.  Same error.

 

I know SSH works (I'm using it right now).   In the AirVPN client, I authorize, it gets to local forwarding, and then kills.  Is this a setting in the client or is something happening with Fedora that's blocking it?

That's the error. It must be 127.0.0.1. How does that happen?

Okay.... that makes sense.     Any idea if this is a client issue or a Linux issue?

Neither of them.

Check your /etc/hosts for the proper IP address of "localhost", it should be 127.0.0.1.

 

Unless you have a line containing

127.0.0.1	localhost

in your /etc/hosts, on any *nix OS, things will behave abnormally.

Bingo!   I have to muck about with my hosts file all the time, and I apparently deleted the first two digits of "home".  I completely missed that.  OOPS!

 

Thank you.  It's so nice when the answer is simple and easy to fix
