lets say you are managing multiple servers at once and you have multiple user accounts with multiple keys from different persons

thats the tool pushing their public keys to servers, adding/removing them automatically from them

first there is users directory where public keys stored even the ones not being used for now

second there is folder machines, it has configs named host.user.conf. where host may be an ip or casual hostname (anyways im passing it to ssh)

some important note about user, username cannot contain dot (for now)

adding or removing users from hosts easy as adding their name or removing them from config file.

users: keys of users (.pub files) machines: username/host pairs and configs for them (including allowed user lists)

git clone http://github.com/pvtmert/kd.git
cd kd
cp ~/.ssh/id_rsa.pub users/myself.pub # add myself to allow all

of course add your own configs, and remove default ones.

just run make as usually you do in source codes...

kd$ make
compiling [email protected]
adding: mert
Enter password for "example machine" if prompted...
[email protected] aka "example machine" is completed

or just one host

kd$ make machines/example.com.admin.conf
compiling [email protected]
adding: john
Enter password for "example.com admin" if prompted...
[email protected] aka "example.com admin" is completed

first line of host file is its common name, like "my web server" or "johns wordpress site"

other lines are the names of users (each on one line) which are public keys allowed (pushed to server)

lines starting with '#' being ignored (comments), also empty lines being ignored too

lets say we have dir structure like this

users:
	id_rsa.pub
	john.pub
	alice.pub
	bob.pub
	guest.pub
	bot.pub
machines:
	example.com.root.conf
	example.com.mod.conf
	example.org.web.conf

okay, so contents of files like that

# example.com
# root's allowed list
# common name:
example.com ROOT account

# myself
id_rsa

# let johnny manage
john

# example.com
# moderator account (mod)
# c-name
example.com moderation

# myself
id_rsa

# mods
alice
bob
bot

# example.org
# web cleanup list
# cname

# myself
id_rsa

# assigned people:
bot
john

note: i'm always adding myself so i dont have to enter password when updating...
