I am on OS X trying to ssh into a ubuntu 12.04 server. I was able to SSH in -- until abruptly stuff stopped working. I've read online to use the
-v to debug this. Output is shown below. If I ssh into a different box and then ssh from that box to the server I am able to login. I have no idea how to debug this problem but would like to learn.
$ ssh -v me@server OpenSSH_6.2p2, OSSLShim 0.9.8r 8 Dec 2011 debug1: Reading configuration data /etc/ssh_config debug1: /etc/ssh_config line 20: Applying options for * debug1: /etc/ssh_config line 53: Applying options for * debug1: Connecting to server [IP] port 22. debug1: Connection established. debug1: identity file /Users/me/.ssh/id_rsa type 1 debug1: identity file /Users/me/.ssh/id_rsa-cert type -1 debug1: identity file /Users/me/.ssh/id_dsa type -1 debug1: identity file /Users/me/.ssh/id_dsa-cert type -1 debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_6.2 ssh_exchange_identification: read: Connection reset by peer
So far (on advice of message boards) I have looked for a hosts deny file -- but there is no such file on my machine.
$ cat /etc/hosts.deny cat: /etc/hosts.deny: No such file or directory
I have admin access on client machine but not on server.
