SSH Config

SSH client config file manager

What is ssh_config?

https://linux.die.net/man/5/ssh_config

Why

I don't remember all the servers I am managing. Also all servers requires all different configuration to connec to it. I know ~.ssh/config can handle this kind of issue. I want it to handle this file easier.

Yes, I am not sure this is eaiser way to handle it. but I am trying.

Use-cases

List hosts

$ ssh-config ls 
# It shows name and HostName attribute
server1: 203.0.113.76
*: None
server_cmd_1: 203.0.113.76
server_cmd_2: 203.0.113.76
server_cmd_3: 203.0.113.76

Add host

$ ssh-config add "server_cmd_4" HostName=203.0.113.77 IdentityFile="~/.ssh/cmd_id_rsa"

Update host

$ ssh-config add --update -p "server_cmd_3" IdentityFile="~/.ssh/cmd_id_rsa"

Remove host

$ ssh-config rm "server_3" 

Using pattern to get list or update exist hosts

List hosts with pattern

$ ssh-config ls "server_*"
# It shows name and HostName attribute
server_cmd_1: 203.0.113.76
server_cmd_2: 203.0.113.76
server_cmd_3: 203.0.113.76

Update hosts with pattern

$ ssh-config add --update -p "server_*" IdentityFile="~/.ssh/cmd_id_rsa"

add ssh key to multiple servers

ssh-config ls --only-name | xargs -I{} ssh-copy-id -i ~/.ssh/id_rsa {}
