Hi,

thanks for answering me :)

My /etc/ssh/sshd_config looks currently like this:
---
Port 5583
Protocol 2
AllowUsers admin user
AddressFamily inet
PasswordAuthentication no
ChallengeResponseAuthentication no
Subsystem sftp /usr/lib/misc/sftp-server
AllowGroups wheel users
LoginGraceTime 20
PermitEmptyPasswords no
PermitRootLogin no
X11Forwarding no
PrintLastLog yes
HostbasedAuthentication no
--

After your email I've set "PubkeyAuthentication yes" to, but it don't change the problem or the error messages :(

uhm, that sshd_config is a backup from my old server-system and there ssh had work very well.

Greets,
Eni

Hi,

please, excuse my terrible english, but can anyone help?
I re-installed my server with Gentoo Linux and after that i get this:

---
$ ssh user@server
permission denied (publickey).
---

/var/log/auth.log says:
---
sshd[8159]: User 'username' from 'domain' not allowed because not listed in 
AllowUsers
---

But the user is listed in /etc/ssh/sshd_config at "AllowUsers" for sure!

---debug end---

I generated the Keys with:
---
"ssh-keygen -b 2048 -t rsa -f ${HOME}/.ssh/user_server"
---

Then copied it to the remote server to
/home/user/.ssh/authorized_keys
and set chmod 600 to authorized_keys.

I can't find the problem, please help.

Thanks in advance,
Eni (Denise Paschen)
