Re: Dropbear support?

If this is from syslog, syslog might not be configured to allow all
logging. That being said, try running the server directly (not as a
service). It looks like both the server and the client send errors to
STDERR. The server log routine (in svr-session.c):

if (!svr_opts.usingsyslog || havetrace)
 {
struct tm * local_tm = NULL;
 timesec = time(NULL);
local_tm = localtime(&timesec);
 if (local_tm == NULL
|| strftime(datestr, sizeof(datestr), "%b %d %H:%M:%S",
 local_tm) == 0)
{
 /* upon failure, just print the epoch-seconds time. */
snprintf(datestr, sizeof(datestr), "%d", (int)timesec);
 }
fprintf(stderr, "[%d] %s %s\n", getpid(), datestr, printbuf);
 }

It looks like error, warning, info, and debug logging all go into STDERR.
In this case, it looks like a majority of the messages are LOG_INFOs.
