If you’re running a rails application with capistrano and you run into the following error:
Error reading response length from authentication socket
When you attempt to connect via cap, for instance
> cap staging deploy
Then make sure you can answer the following questions with a ‘yes’ before continuing.
1) Is my private key properly created and available on my local system. Simple configurations will generally maintain the key at:
~/.ssh/id_rsa
2) Is my public key available on the remote server. If not, you will need to add it to the authorized_keys file on the remote server:
~/.ssh/authorized_keys
Your public key can be found in the following location (on your local machine):
~/.ssh/id_rsa.pub (or whatever your public key pairing is for your situation)
and paste it as a newline in the above file on the remote server (authorized_keys).
If you are still experiencing the authentication socket error, do the following at your local command prompt:
> eval $(ssh-agent)
> ssh-add
This is particularly important if you are using a private:public key pairing and expecting capistrano to allow agent forwarding.
Thanks! this corrected the problem.
thanks.. it solved my error.. great job
Thanks, ssh-add was required!
I tried your steps but still I am getting error… could you please help?

Vijaysinhparmar – it looks like you need to add your public key to your bitbucket account. The error you’re receiving isn’t related to your local client to your remote server, but to your remote server to bitbucket.
