I'm trying to setup passwordless login on two macs, mini and bigmac. It's working on one, not on the other. On each machine:
I use "ssh-keygen -t rsa" to generate id_rsa and id_rsa.pub (pressing enter when asked for a password). I mv the resulting files to ~/.ssh, then scp id_rsa.pub to ~/.ssh/authorized_keys to the opposite Mac.
For ssh from "mini" into "bigmac" the passwordless login works. When I try to ssh from "bigmac" into "mini" I'm asked for a password:
bigmac:~ jedevnull$ cd .ssh bigmac:.ssh jedevnull$ ls authorized_keys id_rsa id_rsa.pub known_hosts bigmac:.ssh jedevnull$ ssh -v mini OpenSSH_6.2p2, OSSLShim 0.9.8r 8 Dec 2011 debug1: Reading configuration data /etc/ssh_config debug1: /etc/ssh_config line 20: Applying options for * debug1: Connecting to mini [192.168.1.20] port 22. debug1: Connection established. debug1: identity file /Users/jedevnull/.ssh/id_rsa type 1 debug1: identity file /Users/jedevnull/.ssh/id_rsa-cert type -1 debug1: identity file /Users/jedevnull/.ssh/id_dsa type -1 debug1: identity file /Users/jedevnull/.ssh/id_dsa-cert type -1 debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_6.2 debug1: Remote protocol version 2.0, remote software version OpenSSH_6.9 debug1: match: OpenSSH_6.9 pat OpenSSH* debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-ctr firstname.lastname@example.org none debug1: kex: client->server aes128-ctr email@example.com none debug1: SSH2_MSG_KEX_DH_GEX_REQUEST(1024<2048<8192) sent debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP debug1: SSH2_MSG_KEX_DH_GEX_INIT sent debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY debug1: Server host key: RSA 0d:2e:de:45:00:ff:9b:ff:96:c5:f6:bd:c6:6a:b0:ec debug1: Host 'mini' is known and matches the RSA host key. debug1: Found key in /Users/jedevnull/.ssh/known_hosts:1 debug1: ssh_rsa_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: Roaming not allowed by server debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey,keyboard-interactive debug1: Next authentication method: publickey debug1: Offering RSA public key: /Users/jedevnull/.ssh/id_rsa debug1: Authentications that can continue: publickey,keyboard-interactive debug1: Trying private key: /Users/jedevnull/.ssh/id_dsa debug1: Next authentication method: keyboard-interactive Password:
bigmac's id_rsa.pub and mini's authorized_keys are the same.
