Trouble with RSA authentication
I finally got sshd working! But I cannot authenticate via RSA. I made the keygen with ssh-keygen in my winbox and copied identity.pub to authorized_keys and identity in my linbox (I have the same files in both machines). I really know how ssh works in linux, but I have some troubles with RSA in cygwin. Below is the message that I got: 12:16:21 marcos@laud~ ssh -i .ssh/identity.mozart -vvv mozart.lab -1 OpenSSH_3.4p1 Debian 1:3.4p1-1, SSH protocols 1.5/2.0, OpenSSL 0x0090603f debug1: Reading configuration data /etc/ssh/ssh_config debug1: Rhosts Authentication disabled, originating port will not be trusted. debug1: ssh_connect: needpriv 0 debug1: Connecting to mozart.lab [163.117.144.225] port 22. debug1: Connection established. debug1: identity file .ssh/identity.mozart type 0 debug1: Remote protocol version 1.99, remote software version OpenSSH_3.4p1 debug1: match: OpenSSH_3.4p1 pat OpenSSH* debug1: Local version string SSH-1.5-OpenSSH_3.4p1 Debian 1:3.4p1-1 debug1: Waiting for server public key. debug1: Received server public key (768 bits) and host key (1024 bits). debug3: check_host_in_hostfile: filename /users/tec/marcos/.ssh/known_hosts2 debug3: check_host_in_hostfile: filename /etc/ssh/ssh_known_hosts2 debug3: check_host_in_hostfile: filename /users/tec/marcos/.ssh/known_hosts2 debug3: check_host_in_hostfile: filename /etc/ssh/ssh_known_hosts2 debug3: check_host_in_hostfile: filename /users/tec/marcos/.ssh/known_hosts debug3: check_host_in_hostfile: match line 45 debug3: check_host_in_hostfile: filename /users/tec/marcos/.ssh/known_hosts debug3: check_host_in_hostfile: match line 44 debug1: Host 'mozart.lab' is known and matches the RSA1 host key. debug1: Found key in /users/tec/marcos/.ssh/known_hosts:45 debug1: Encryption type: 3des debug1: Sent encrypted session key. debug1: cipher_init: set keylen (16 -> 32) debug1: cipher_init: set keylen (16 -> 32) debug1: Installing crc compensation attack detector. debug1: Received encrypted confirmation. debug1: Trying RSA authentication with key '.ssh/identity.mozart' debug1: Server refused our key. debug1: Doing challenge response authentication. debug1: No challenge. debug1: Doing password authentication.

Looks like the server logs with debugging enabled will hold the necessary info to debug this.

RE: Trouble with RSA authentication
/usr/doc/Cygwin/openssh-3.4p1-5.README states that RSA authentication only
works if sshd runs under a user account (as opposed to the SYSTEM account).
To that end, I've created 2 shell scripts to allow one to "switch" from
running sshd as SYSTEM to running as a user, and visa versa.
These scripts will also fix the '/var/empty' problem, so they are worthwhile
to run once, even if you will never switch.
I haven't tried it, but you could probably even have a user and a SYSTEM
daemon running at the same time, by running one of the daemons on another
port via the -p option.
Attached and inline are the scripts.
I'll also put the latest versions up at http://www.netebb.com/cygwin/.
I'd love to see these incorporated into cygwin's openssh (or at least a user
contribs) package.
I'm not a cygwin wizard, so feedback is appreciated.
