I am confused (as usually is the case when I see someone trying to
describe a client/server setup):

There are at least two computers involved here:
  A  -- your desktop/laptop
  B  -- your client's server
Is this correct so far?

Now, A is running Gentoo. Correct?

What is B running?
Are you trying to SSH from A to B, or are you trying to SSH from B to
A?

When you say you can't login with SSH through shared keys, does that
mean you can log-in through password? 

 When I made the world update, there was the package udev. I guess it
 might have something todo with this.

Why would you think udev is causing the problem? Udev manages devices,
I fail to see what it has to do with SSH and public key
authentication. Rather than guessing by yourself, you may be better
off providing the whole list of recently updated packages. You can use
'genlop' or 'qlop' for that, or you can just read /var/log/emerge.log
by hand.

The OP has not given any information at all that will help resolve this.

Tamer, the answer will be in your log files. But before you do that you need 
to do some basic fault-finding yourself. Start by verifying that sshd is 
actually running on the server. If the server is the remote machine, nmap is 
what you need for that test.

As Willie writes, you do not provide much information. Try ssh -v
destination, this gives some debug information. Also try -vv and -vvv
to get even more.

 might have something todo with this.

I would be surprised. But sometimes I am.
