2020-03-18Improve address logging on early exit messages (#83)Kevin Darbyshire-Bryant
Change 'Early exit' and 'Exit before auth' messages to include the IP address & port as part of the message. This allows log scanning utilities such as 'fail2ban' to obtain the offending IP address as part of the failure event instead of extracting the PID from the message and then scanning the log again for match 'child connection from' messages Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk>

2018-02-26Fix restricted group code for BSDs, move to separate functionMatt Johnston
2018-02-20Added the -G option to allow logins only for users that are members of a ↵stellarpower
certain group. This allows finer control of an instance on who can and cannot login over a certain instance (e.g. password and not key). Needs double-checking and ensuring it meets platform requirements.

2017-06-25dropbear server: support -T max auth triesKevin Darbyshire-Bryant
Add support for '-T n' for a run-time specification for maximum number of authentication attempts where 'n' is between 1 and compile time option MAX_AUTH_TRIES. A default number of tries can be specified at compile time using 'DEFAULT_AUTH_TRIES' which itself defaults to MAX_AUTH_TRIES for backwards compatibility.
