- OpenBSD CVS updates
- [channels.c cipher.c compat.c log-client.c scp.c serverloop.c]
[ssh.h sshd.8 sshd.c]
syslog changes:
* Unified Logmessage for all auth-types, for success and for failed
* Standard connections get only ONE line in the LOG when level==LOG:
Auth-attempts are logged only, if authentication is:
a) successfull or
b) with passwd or
c) we had more than AUTH_FAIL_LOG failues
* many log() became verbose()
* old behaviour with level=VERBOSE
- [readconf.c readconf.h ssh.1 ssh.h sshconnect.c sshd.c]
tranfer s/key challenge/response data in SSH_SMSG_AUTH_TIS_CHALLENGE
messages. allows use of s/key in windows (ttssh, securecrt) and
ssh-1.2.27 clients without 'ssh -v', ok: niels@
- [sshd.8]
-V, for fallback to openssh in SSH2 compatibility mode
- [sshd.c]
