I've got Git for Windows (configured for MinTTY and `PuTTY\plink.exe`) and PuTTY installed, and I am trying to get it to work with a Bitbucket repository. I've got my SSH key loaded, in Pageant and on the website, and yet whenever I attempt to do anything that requires pulling/pushing:

```
Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

```

When I run the suggested `ssh -v hg@bitbucket.org` it uses `id_rsa` but none of my other keys in `~/.ssh`. Trying to use `ssh-add ~/.ssh/bitbucket_rsa` results in:

```
Could not open a connection to your authentication agent.

```

I've read about configuring PuTTY to allow forwarding, but that's usually where the advice ends, so I just set this option for the default session and saved it there.

I've run `ps` to check which applications were running, and `ssh-agent` was not among them. Running `eval 'ssh-agent'` starts the daemon, but it makes no difference.
