Occasionally I’ll receive this error when trying to connect to VPN when using Mac’s built-in Cisco VPN client.

A configuration error occurred. Verify your settings and try reconnecting.

  501   349   335   0   0:00.00 ttys001    0:00.00 grep racoon

Then try and reconnect to VPN. That’ll save you from having to reboot to fix your VPN.

    Works for me.

    racoon is some key management program, and it seems like it will be restarted by the VPN client.

    I did:

    sudo killall racoon

    Then vpn worked, and racoon was running again per ‘ps -ef’
