Dropbear client configuration file?

Question

Does anybody know where the Dropbear SSH client looks for a config file? I need to specify a certain identity file to be used by default. Eg, can I setup dropbear client such that I can use

$ dbclient user@host

instead of

$ dbclient -i my/rsa/key user@host

?

PS: I'm pretty much stuck with Dropbear rather than OpenSSH since I am on embedded linux running Angstrom.

EDIT: Alternatively, where does the dropbear client look for an identity file by default?

Answer 1

New dropbear (v2017 ..) has a default id .ssh/id_dropbear see help: -i <identityfile> (multiple allowed, default .ssh/id_dropbear)
