ssh-agent on MAC OS X Lion - sometimes it requests ssh password

Question

I have a DataFrame that looks like this:

               spot      total
date_delivery       
2016-06-21       x            20
2016-07-25       x            22
2016-08-14       x            25
2016-09-11       y            16
2016-10-16       y            10

The index of the DataFrame is in a datetime format. I want to create a simple graph for each unique spot that shows the total over time. I am having trouble writing a loop that performs this as well as saves each one. Keep in mind that while there is only 2 actual spots in this DataFrame the real one has many many more.

Solution

On OS X Lion, ssh-agent is configured to start at boot by default. And ssh-agent will always load your default keys (~/.ssh/id_rsa and ~/.ssh/id_dsa). If you have multiple ssh keys (I have one for each client/project) and want ssh-agent to remember them across restarts:

ssh-add -K ~/.ssh/your-other-key

I give mine an expiration as well, although honestly, I don't know if it matters, since the -K adds it to keychain and I believe the expiration is just the agent. Anyway:

ssh-add -K -t 7776000 ~/.ssh/my-other-key

Thanks! This worked. How would I save all of them without doing it manually?

import matplotlib.pyplot as plt, then plt.savefig('myfig.jpg') for example. Pretty sure you'll have to loop over your groupby object in order to save each individually.
