getting ssh_exchane_identity error when trying to login from my machine or a remote one. Already enabled remote login

Hi Linc

here is the output of ssh -vvv localhost

The following line comes from /var/log/secure.log

May 23 04:59:46 <danielamaurizio> sshd[2267]: fatal: /var/empty must be owned by root and not group or world-writable.

but I'm not sure if it's want you asked me; the owner of /var/empty is root of group sys.

By the way I had a problem that Lion cancelled the owner root and I had to use System Preferences User and groups to add root again, with the result that now I can use only the comman "su root" and not "sudo anycommand" anymore.

Thanks for halp and cheers

ok, but what about my original problem with ssh? do tou think that your last suggestion will solve this problem too?

Hi Linc

sorry I didn't write before but I had internet line problems.

Following your suggestion of your second post,I couldn't recreate a root account (the setup assistant didn't let me do it), only another user account and it didn't solve the problem. From the report you asked me I realized that it could have been a permission problem. The Apple Disk Utility showed that almost all the apple files had wrong permissions, so I asked a permission repair and this solved both mentioned problems. The mystery is: how and when this happened on my disk? I'm not conscious of any action I did to get that mess!!

Anyway thanks for the first suggestion.

Cheers
