ssh-add add all private keys in .ssh directory

Question

My CSS file is located here: /Areas/Car/Views/Shared/CSS/css.css. I reference it in my code like this:

<link href="@Url.Content("/Areas/Car/Views/Shared/CSS/css.css")" rel="stylesheet" type="text/css" />

However, C# is throwing a 404 error for that link.

I've tried adding a context.MapRoute:

context.MapRoute(
    "CSS",
    "/Areas/Car/Views/Shared/{action}/{id}",
    new { controller = "Car", action = "CSS", id = UrlParameter.Optional }
};

And then accessing it with /Car/CSS/css.css (and all the variations I can think of)

But I am still getting the same error. If, however, I reference a different css file - not in Areas - it works fine. What am I doing wrong?

Solution 1

Slightly convoluted, but:

for possiblekey in ${HOME}/.ssh/id_*; do
    if grep -q PRIVATE "$possiblekey"; then
        ssh-add "$possiblekey"
    fi
done

You can also add all of your keys to your ~/.ssh/config each in their own IdentityFile directive outside of a Host directive:

# Global SSH configurations here will be applied to all hosts
IdentityFile ~/.ssh/id_dsa
IdentityFile ~/.ssh/id_project1
IdentityFile ~/.ssh/id_someotherkey

Host somespecifichost.example.com
    IdentityFile ~/.ssh/id_specifichostonlykey

The latter, honestly-better, method has the added perk of not suddenly picking up a new key that you've added without you explicitly adding it to the "keyring" as it were.

Solution 2

I have come up with the following command to do this:

find ~/.ssh/ -type f -exec grep -l "PRIVATE" {} \; | xargs ssh-add &> /dev/null

This will find all files in the .ssh directory that contain PRIVATE, passing the name / path of the private key file to ssh-add.

Solution 3

You don't really need find, you can just use a recursive grep using the l flag to send only matching filenames:

grep -slR "PRIVATE" ~/.ssh/ | xargs ssh-add

Is there a reason you need to add all these keys? If you specify the IdentityFile for each host inside your ~/.ssh/config file, ssh will use that file when you try to connect.

Using Amazon AWS, my host IP address are ephemeral, and are constantly changing ( test stacks ). I can not rely on a config file to always be correct. Each layer of the stack has different user permissions.

ohhh, good call. I did not actually know that IdentifyFile definitions could exist outside of a Host.

Unfortunately this can prevent you from connecting to a server if you have many keys, claiming Too many authentication failures as it tries each key one by one for all servers, and some disconnect after a certain number of incorrect keys are tried.

This is the best way out of these answers if you have multiple keys with the same passphrase, as you will only have to enter it once.
