ssh connection without password
The subject has been outlined in many articles, yet I can not establish a password-less ssh connection. Below I show what I did and then I include ssh debug info, maybe someone would be able to point out something I am not doing right. My setup: two SCO 5.0.7 boxes on a private lan, user equivalency established, rcmd/rcp working from one to another just fine. The user account, which is the same on both sides, has no password. on both boxes: Code:
$ grep -v '^#' /etc/ssh/sshd_config | grep -v '^$' RSAAuthentication yes PubkeyAuthentication yes Subsystem sftp /usr/lib/openssh/sftp-server On my source box I generated public key Code:
$ ssh-keygen -t rsa $ l -g -rw------- 1 group 887 May 29 11:39 id_rsa -rw-r--r-- 1 group 229 May 29 11:39 id_rsa.pub And I copied pub file to the target box On the target box: Code:
$ cd; mkdir .ssh; chmod 700 .ssh; l -dg .ssh drwx------ 2 group 512 May 29 11:33 .ssh $ cd .ssh $ cat ../my_pub > authorized_keys; chmod 600 authorized_keys $ l -g -rw------- 1 group 229 May 29 11:33 authorized_keys Now, when I try to connect from my source box: Code:
$ ssh -v target_server OpenSSH_3.8p1, SSH protocols 1.5/2.0, OpenSSL 0.9.7d 17 Mar 2004 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Connecting to target_server [192.168.1.74] port 22. debug1: Connection established. debug1: identity file /u/target_user/.ssh/identity type -1 debug1: identity file /u/target_user/.ssh/id_rsa type 1 debug1: identity file /u/target_user/.ssh/id_dsa type -1 debug1: Remote protocol version 1.99, remote software version OpenSSH_4.3 debug1: match: OpenSSH_4.3 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_3.8p1 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-cbc hmac-md5 none debug1: kex: client->server aes128-cbc hmac-md5 none debug1: SSH2_MSG_KEX_DH_GEX_REQUEST(1024<1024<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: Host 'target_server' is known and matches the RSA host key. debug1: Found key in /u/target_user/.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: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey,password,keyboard-interactive debug1: Next authentication method: publickey debug1: Trying private key: /u/target_user/.ssh/identity debug1: Offering public key: /u/target_user/.ssh/id_rsa debug1: Authentications that can continue: publickey,password,keyboard-interactive debug1: Trying private key: /u/target_user/.ssh/id_dsa debug1: Next authentication method: keyboard-interactive debug1: Authentications that can continue: publickey,password,keyboard-interactive debug1: Next authentication method: password target_user@target_server's password: debug1: Authentications that can continue: publickey,password,keyboard-interactive Permission denied, please try again. target_user@target_server's password: I see message "ssh_rsa_verify: signature correct" in the debug, which looks like a promising sign, but something is not clicking and it does ask for password, which is removed for this user account, so it is no go. Any pointers would be appreciated. Last edited by migurus; 05-29-2009 at 05:14 PM.. Reason: forgot to show sshd_config |
