The authenticity of host 'people.apache.org (209.237.237.194)' can't be
established.
RSA key fingerprint is 51:85:7d:8f:57:54:e7:6f:27:26:98:7a:c7:c1:47:87.
Are you sure you want to continue connecting (yes/no)?
The fingerprints for `people.apache.org` can be found
[here](new-committers-guide.html#spoof). If the user elects to continue
then this value will be written to a `known_hosts` file. In future, when
the user connects to the same server, this value will be checked and the
user alerted if it has changed.
Please do not continue the connection after such an alert: contact
infrastructure. This is of crucial importance when using keyboard
interactive authentication.
**Note:** the fingerprint for the key used for ssh is different to the
fingerprint of the certificate used to [securely serve the
website](version-control.html#cert).

# Using OpenSSH To Connect To Apache # {#openssh}
[OpenSSH](http://www.openssh.org) is a widely used and trusted suite of
software using the SSH family of protocols.
## Configuring OpenSSH To Use SSH2 (*nix) ## {#openssh-ssh2}
The OpenSSH client uses (by default) configuration files in the `~/.ssh`
directory. The main configuration file is `~/.ssh/config` and is optional.
In other words, it may or may not exist already. If it does not then it
should be created.
A simple text format is used. Instructions for a particular host (or group
of hosts) are grouped together. The following is a suggested basic
configuration:
