I've inherited the administration of a linux box in my workplace; it was set up by a colleague who is now gone. Recently, I added a new user to the system, and tried to give her ssh access as well; the way most people who use the machine access it. This, I can't get to work.
Here's what happens:
scmb-bkobe03m:~ xzhang$ ssh -v -X -p 22 arwen@myServer OpenSSH_5.2p1, OpenSSL 0.9.8r 8 Feb 2011 debug1: Reading configuration data /etc/ssh_config debug1: Connecting to myServer [152.98.xx.xx] port 22. debug1: Connection established. debug1: identity file /Users/xzhang/.ssh/identity type -1 debug1: identity file /Users/xzhang/.ssh/id_rsa type 1 debug1: identity file /Users/xzhang/.ssh/id_dsa type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_5.5p1 Debian-6+squeeze2 debug1: match: OpenSSH_5.5p1 Debian-6+squeeze2 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.2 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: Host '[myServer]:22' is known and matches the RSA host key. debug1: Found key in /Users/xzhang/.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 debug1: Next authentication method: publickey debug1: Trying private key: /Users/xzhang/.ssh/identity debug1: Offering public key: /Users/xzhang/.ssh/id_rsa debug1: Authentications that can continue: publickey debug1: Trying private key: /Users/xzhang/.ssh/id_dsa debug1: No more authentication methods to try.
Now, I have of course added her public ssh-key to authorized_keys. So I had a look in /var/log/auth.log and found
Jan 7 11:37:12 sauron sshd: User arwen from myClientMachine not allowed because not listed in AllowUsers
Which is funny since I did add her to AllowUsers:
daniel@sauron:~$ sudo more /etc/ssh/sshd_config | grep AllowUsers AllowUsers jonathan daniel rafael simon thomas li arwen
I don't know where to go from here. Any takers?
