Hello everybody
I tried use ssh but I cant.I have two linux machine.I written ssh -keygen -t dsa in consol and One file is made in /home/wampire/.ssh/id_dsa.pub .And I have to copy id_dsa.pub file another linux machine in /home/user/.ssh/ but I can't have .ssh directory in other linux machine.But sshd is already run on system.I need some help.Good day

I don't know how you can use SSH only between to systems with static IP but I suppose you can to configure it through iptables.
First of all sshd service must be running on both systems. You need also to check you ssh_config file in /etc/ssh folder. Be sure that you have this line disabled otherwise you'll not be able to connect to or from.

# PasswordAuthentication no

After you are sure ssh is running in order to connect you type in the console:

ssh username@ip

If you type just ssh ip then you will be connected as the user that you are logged in your system.

I hope you will find this information usefull.

Yes I did this what you say.And ssh user@ip then consol says that "ssh: connect to host 10.x.x.x port 22: No route to host ".But Host is already run sshd...

Do you use any kind of firewall? Try also to ping the other system to see if it responds.

Means that your system is on a different IP subnet than the one it is trying to connect to AND it has no route table entry for a router that knows how to get there.

Is this 10.xx.xx.xx host across The Internet from you? if so it is behind a NAT and you can't directly access it unless the administrator of that network opens a port forward to the system for you.
