| ExpandCreating a new ssh key pair for no-password access to a remote system |
|---|
wow I just had serious issues with basic ssh usage, so i'll put a summary on the wiki
basically most misunderstandings stem from describing these two:
client: machine that is trying to ssh into the server
server: machine that the client user wants to get to
most poor sots are just sitting on the client
and they create a pair and push their public key to the server
but in my case, more often, i want to create a pair on the server
and push the private key to the multiple places i need to connect FROM
when doing that, you have to push the public key into the server's authorized_keys
and configure the client to juggle multiple private keys
create a key pair:
ssh suser@server
ssh-keygen
use defaults
will create:
.ssh/id_rsa (private key)
.ssh/id_rsa.pub (public key)
put the public key in place:
cd .ssh
cat id_rsa.pub >>authorized_keys
put the private key on the client and configure:
scp id_rsa cuser@client:.ssh/id_rsa_server
ssh cuser@client
em .ssh/config
Host tdm thedigitalmachine.com
Hostname thedigitalmachine.com
IdentityFile ~/.ssh/id_rsa
User m
Host server
Hostname server.com
IdentityFile ~/.ssh/id_rsa_server
User suser
all is full of light
