Then get someone who can to analyze the problem.

The thing is that I did not change anything in the sshd config, but simply generated the keys. You think this may be related?

No, not at all. But ssh-communication requires two things to work in accordance: the client side (ssh-client, authentication data) and the server side (the sshd daemon and its configuration).

I don't claim to know what went wrong in your case, but the debug output you provided makes me suppose the problem is with the server side. To verify this one will have to examine the server configuration and eventually reconfigure/restart it, as i have told you.

Alternatively you can try to set up communication from a third host to the problematic one: if i got you correctly "HostA->HostB" works, but "HostB->HostA" doesn't. Set up "HostC->HostA" and see if this works. If it does it is probably not the sshd in host A as such, but maybe just the configuration: there are different versions of open-ssl (the library which does the underlying encryption) and maybe you hit upon such a version incompatibility.

Fact is: i don't know and as long as you can't present more and better data probably nobody can. So we are left to suggestions and more or less educated guesses about possible reasons.

I hope this helps.

chsh

CHSH(1) 							   User Commands							   CHSH(1)

NAME

       chsh - change your login shell

SYNOPSIS

       chsh [-s shell] [-l] [-u] [-v] [username]

DESCRIPTION

       chsh is used to change your login shell.  If a shell is not given on the command line, chsh prompts for one.

       chsh is used to change local entries only. Use ypchsh, lchsh or any other implementation for non-local entries.

OPTIONS

       -s, --shell shell
	      Specify your login shell.

       -l, --list-shells
	      Print the list of shells listed in /etc/shells and exit.

       -u, --help
	      Print a usage message and exit.

       -v, --version
	      Print version information and exit.

VALID SHELLS

       chsh  will  accept  the full pathname of any executable file on the system.  However, it will issue a warning if the shell is not listed in
       the /etc/shells file.  On the other hand, it can also be configured such that it will only accept shells listed in this	file,  unless  you
       are root.

EXIT STATUS

       Returns 0 if operation was successful, 1 if operation failed or command syntax was not valid.
