Title: Permission denied (publickey)
Post by: ElFroggio on December 20, 2016, 11:02:32 PM: SME 9.1

Today I tried to log on through the web interface and it wouldn't, so I did ssh admin@192.168.1.14 and got the following message:

Code: [Select]
ssh admin@192.168.1.14 Permission denied (publickey).
When login as root I have no problem. I reset the admin password just in case. But 'no dice'.

Last login from admin was 2 days ago and it was successful and as far as I know, nothing has changed.

Code: [Select]
[froggy@dodoite ~]$ ssh -v admin@192.168.1.14 OpenSSH_7.3p1, OpenSSL 1.0.2j 26 Sep 2016 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Connecting to 192.168.1.14 [192.168.1.14] port 22. debug1: Connection established. debug1: identity file /home/froggy/.ssh/id_rsa type 1 debug1: key_load_public: No such file or directory debug1: identity file /home/froggy/.ssh/id_rsa-cert type -1 debug1: key_load_public: No such file or directory debug1: identity file /home/froggy/.ssh/id_dsa type -1 debug1: key_load_public: No such file or directory debug1: identity file /home/froggy/.ssh/id_dsa-cert type -1 debug1: key_load_public: No such file or directory debug1: identity file /home/froggy/.ssh/id_ecdsa type -1 debug1: key_load_public: No such file or directory debug1: identity file /home/froggy/.ssh/id_ecdsa-cert type -1 debug1: key_load_public: No such file or directory debug1: identity file /home/froggy/.ssh/id_ed25519 type -1 debug1: key_load_public: No such file or directory debug1: identity file /home/froggy/.ssh/id_ed25519-cert type -1 debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_7.3 debug1: Remote protocol version 2.0, remote software version OpenSSH_5.3 debug1: match: OpenSSH_5.3 pat OpenSSH_5* compat 0x0c000000 debug1: Authenticating to 192.168.1.14:22 as 'admin' debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: algorithm: diffie-hellman-group-exchange-sha256 debug1: kex: host key algorithm: ssh-rsa debug1: kex: server->client cipher: aes128-ctr MAC: umac-64@openssh.com compression: none debug1: kex: client->server cipher: aes128-ctr MAC: umac-64@openssh.com compression: none debug1: SSH2_MSG_KEX_DH_GEX_REQUEST(2048<3072<8192) sent debug1: got SSH2_MSG_KEX_DH_GEX_GROUP debug1: SSH2_MSG_KEX_DH_GEX_INIT sent debug1: got SSH2_MSG_KEX_DH_GEX_REPLY debug1: Server host key: ssh-rsa SHA256:bQQEOvcIOPVzBDtYFpP91g/1oU6pXCuqy9Pe8+lQ4XQ debug1: Host '192.168.1.14' is known and matches the RSA host key. debug1: Found key in /home/froggy/.ssh/known_hosts:6 debug1: rekey after 4294967296 blocks debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: rekey after 4294967296 blocks debug1: SSH2_MSG_NEWKEYS received debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey debug1: Next authentication method: publickey debug1: Offering RSA public key: /home/froggy/.ssh/id_rsa debug1: Authentications that can continue: publickey debug1: Trying private key: /home/froggy/.ssh/id_dsa debug1: Trying private key: /home/froggy/.ssh/id_ecdsa debug1: Trying private key: /home/froggy/.ssh/id_ed25519 debug1: No more authentication methods to try.

I have checked my .ssh local directory and it's identical to my previous weekly backup, when it was working

Here is root which works:

try 'ssh root@YOURIP'

It works.

For me the problem is the admin account. I can't connect, I can't log in through the web interface: server-manager

Thanks

Post by: Stefano on December 21, 2016, 04:02:17 PM: ok..

how did you change admin's password (see your initial post)?
Title: Re: Permission denied (publickey)
Post by: Stefano on December 21, 2016, 04:03:35 PM: BTW, you can log in in ssh as root and then use

Code: [Select]
console
to reach the console and
Code: [Select]
elinks
to see server-manager..

ok..

Yes at the console, no at my desk.

Which log file keeps track of the web failed/errors for signing in into server-manager?

Thanks

Post by: Stefano on December 21, 2016, 05:16:28 PM: well.. elinks is a browser.. a text one, but a browser.. if you can log in in server-manager using elinks it means that authentication is working..

I guess it's something related to your client.. or to something you did..

can you give us as much details as you can, please? did you try from another client? with a different browser?

Today I tried to log on through the web interface and it wouldn't

what do you see in the browser? can you reach server-manager? if you try to authenticate, which error message do you see?

please, be verbose, we can't see your screen, we don't know anything about your server.. help us to help you, thank you

Here's the screen capture after trying to login as admin: http://i.imgur.com/x5FvidH.png (http://i.imgur.com/x5FvidH.png)

I do not see any error message. That's why I was asking which log file would record/debug the failure.

Tonight when I get back my laptop, I try another it on it.

Thanks
