SSH: localhost closes the connection after a successful login

Question

When I try to execute ssh in localhost, it takes the public key and closes the connection immediately. I’ve been browsing Google’s results pages for several hours without any success. Here is what I get after ssh -v user@localhost :

 OpenSSH_5.9p1, OpenSSL 0.9.8r 8 Feb 2011 debug1: Reading configuration data /Users/user/.ssh/config debug1: Reading configuration data /etc/ssh_config debug1: /etc/ssh_config line 20: Applying options for * debug1: Connecting to localhost [::1] port 22. debug1: Connection established. debug1: identity file /Users/user/.ssh/id_rsa type -1 debug1: identity file /Users/user/.ssh/id_rsa-cert type -1 debug1: identity file /Users/user/.ssh/id_dsa type 2 debug1: identity file /Users/user/.ssh/id_dsa-cert type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_5.9 debug1: match: OpenSSH_5.9 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.9 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-ctr hmac-md5 none debug1: kex: client->server aes128-ctr 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: Server host key: RSA 67:2f:0b:c8:40:e8:87:0f:57:ee:c7:68:ae:8a:5a:02 debug1: Host 'localhost' is known and matches the RSA host key. debug1: Found key in /Users/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: 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: Trying private key: /Users/user/.ssh/id_rsa debug1: Offering DSA public key: /Users/user/.ssh/id_dsa debug1: Server accepts key: pkalg ssh-dss blen 433 debug1: read PEM private key done: type DSA Connection closed by ::1 

I am running OSX 10.8 using ssh via Terminal.

Answer 1

Ok, so it finally worked, explicitly allowing connections from user . Installing System Prefs > Sharing > Remote Login > Allow access for: in All Users does not work; instead, I had to check Only these users: and manually add all users. Hope this helps someone else with the same issue.

Answer 2

For a long time I had the same problem with Telnet, and if I remember it well, the problem was that the user does not have a home directory in / etc / passwd. I assume that you are trying to create a connection without a password, right? When you google, there is a good explanation here: http://diuf.unifr.ch/main/tech/node/57 Also it explains how to quickly make the password less connected http: //greg-n-blog.blogspot. com / search / label / scp

This worked for me in Cygwin, using Windows in a large domain:

Add your Windows user ID to /etc/passwd . You can get it by typing $ mkpasswd -d | grep [username] mkpasswd -d | grep [username] . In a large area, it may take you several hours.

Make sure the user ID specified in /etc/passwd matches the ID $ id -u and the group ID matches the name for administrators in /etc/group
