# ssh-agent plugin
|
|
|
|
This plugin starts automatically `ssh-agent` to set up and load whichever
|
|
credentials you want for ssh connections.
|
|
|
|
To enable it, add `ssh-agent` to your plugins:
|
|
|
|
```zsh
|
|
plugins=(... ssh-agent)
|
|
```
|
|
|
|
## Settings
|
|
|
|
**IMPORTANT: put these settings _before_ the line that sources oh-my-zsh**
|
|
|
|
### `agent-forwarding`
|
|
|
|
To enable **agent forwarding support** add the following to your zshrc file:
|
|
|
|
```zsh
|
|
zstyle :omz:plugins:ssh-agent agent-forwarding yes
|
|
```
|
|
|
|
### `helper`
|
|
|
|
To set an **external helper** to ask for the passwords and possibly store
|
|
them in the system keychain use the `helper` style. For example:
|
|
|
|
```zsh
|
|
zstyle :omz:plugins:ssh-agent helper ksshaskpass
|
|
```
|
|
|
|
### `identities`
|
|
|
|
To **load multiple identities** use the `identities` style (**this has no effect
|
|
if the `lazy` setting is enabled**). For example:
|
|
|
|
```zsh
|
|
zstyle :omz:plugins:ssh-agent identities id_rsa id_rsa2 id_github
|
|
```
|
|
|
|
**NOTE:** the identities may be an absolute path if they are somewhere other than
|
|
`~/.ssh`. For example:
|
|
|
|
```zsh
|
|
zstyle :omz:plugins:ssh-agent identities ~/.config/ssh/id_rsa ~/.config/ssh/id_rsa2 ~/.config/ssh/id_github
|
|
# which can be simplified to
|
|
zstyle :omz:plugins:ssh-agent identities ~/.config/ssh/{id_rsa,id_rsa2,id_github}
|
|
```
|
|
|
|
### `lazy`
|
|
|
|
To **NOT load any identities on start** use the `lazy` setting. This is particularly
|
|
useful when combined with the `AddKeysToAgent` setting (available since OpenSSH 7.2),
|
|
since it allows to enter the password only on first use. _NOTE: you can know your
|
|
OpenSSH version with `ssh -V`._
|
|
|
|
```zsh
|
|
zstyle :omz:plugins:ssh-agent lazy yes
|
|
```
|
|
|
|
You can enable `AddKeysToAgent` by passing `-o AddKeysToAgent=yes` to the `ssh` command,
|
|
or by adding `AddKeysToAgent yes` to your `~/.ssh/config` file [1].
|
|
See the [OpenSSH 7.2 Release Notes](http://www.openssh.com/txt/release-7.2).
|
|
|
|
### `lifetime`
|
|
|
|
To **set the maximum lifetime of the identities**, use the `lifetime` style.
|
|
The lifetime may be specified in seconds or as described in sshd_config(5)
|
|
(see _TIME FORMATS_). If left unspecified, the default lifetime is forever.
|
|
|
|
```zsh
|
|
zstyle :omz:plugins:ssh-agent lifetime 4h
|
|
```
|
|
|
|
### `quiet`
|
|
|
|
To silence the plugin, use the following setting:
|
|
|
|
```zsh
|
|
zstyle :omz:plugins:ssh-agent quiet yes
|
|
```
|
|
|
|
### `ssh-add-args`
|
|
|
|
To **pass arguments to the `ssh-add` command** that adds the identities on startup,
|
|
use the `ssh-add-args` setting. You can pass multiple arguments separated by spaces:
|
|
|
|
```zsh
|
|
zstyle :omz:plugins:ssh-agent ssh-add-args -K -c -a /run/user/1000/ssh-auth
|
|
```
|
|
|
|
These will then be passed the the `ssh-add` call as if written directly. The example
|
|
above will turn into:
|
|
|
|
```zsh
|
|
ssh-add -K -c -a /run/user/1000/ssh-auth <identities>
|
|
```
|
|
|
|
For valid `ssh-add` arguments run `ssh-add --help` or `man ssh-add`.
