Permission denied (publickey,gssapi-with-mic,password) ssh error

  • 772

Heads up I'm a noob with linux and networking.

I set up a ubuntu server and I have a static ip for my network. When I try to connect to the server at home (external), it prompts me to log in. I supply the correct password (or incorrect pw), I get the error Permission denied, please try again.

and after 3 times I get

Permission denied (publickey,gssapi-with-mic,password)

I am however able to connect with SSH from another computer in the same network with ssh < internal ip of server >

I'm connecting with mac os x and my config file is vanilla.

Note: During installation of ubuntu it says I don't have a default route or something while doing auto network configuration, but I ignored it and continued the installation, could this be the problem?

EDIT:

I have tried the below, I have nothing in hosts.allow and also iptables shows the ports that I have allowed, which is 22.

I checked the auth.log, and there is nothing when I connect to it remotely (even when it says permission denied). I have tried connecting to it internally and the correct authentication logs show. Any idea whats wrong?

ubuntu ssh

  1. It sounds like your ssh server is only allow login from specific IP. Check /etc/hosts.allow if you see something like this:

    sshd: IP

    Also check if you have iptables is running:

    iptables -L -v -n

    Take a look at /var/log/auth.log, it will tell you more details.
