Issue
I am trying to set up my ssh config on the Mac (Mac OS Sierra 10.12.6) in such a way that it stores the passphrase for my ssh key in the keychain. Previously I could do that with
ssh-add -K ~/.ssh/id_rsa
But recently this doesn't seem to work anymore. Following this article there seems to be a change in the behaviour of the ssh config in Mac OS > 10.12.2 and the recommended way to fix this issue is to add UseKeychain yes
to your ssh config. So here's my .ssh/config
section the Host *
:
Host *
Port 22
ServerAliveInterval 60
ForwardAgent yes
IdentityFile ~/.ssh/id_rsa
AddKeysToAgent yes
UseKeychain yes
When trying to ssh to a foreign host, I get the following error message:
$ ssh my-host
/Users/USER/.ssh/config: line 16: Bad configuration option: usekeychain
Any ideas why this happens and how I can fix it? Thanks!
Solution
Try to specify another option, namely IgnoreUnknown
like below:
Host *
IgnoreUnknown UseKeychain
UseKeychain yes
You can find more info about this here.
If you already have an IgnoreUnknown
value, use comma separated values
Host *
IgnoreUnknown AddKeysToAgent,UseKeychain
AddKeysToAgent yes
UseKeychain yes
If you have multiple Host
configs that use the UseKeychain
option, make sure to put
Host *
IgnoreUnknown UseKeychain
before the first host that uses the the option, e.g. put it at the top of the file.
