-	Now the dirty hack: to make sshd start on boot, edit root's .bashrc on the simulated environment:	+
-	[root@(none) ~]# vi .bashrc	+
-	and at the end of the file add this line:	+
-	/etc/init.d/sshd start	+
-	then save and exit, and source your .bashrc:	+
-		+
-	[root@(none) ~]# source .bashrc	+

-	This surely is a dirty way to make it start sshd on boot, but we didn't find a better way (<tt>chkconfig sshd </tt> on did not work).	+
-	Now you should be able to ssh to the simulated environment, running	+
-	$ ssh root@172.20.0.2	+
-	at the bash prompt on your host. But there's a problem: in the simulated environment changing the password with passwd gave an error message. We solved it appending our public keys in the simulated environment:	+
-	At your host prompt, generate your public keys:	+
-	$ ssh-keygen -t rsa	+
-	Now, from the simulated environment, copy your key file, and then append it to your authorized_keys file.	+
-	[root@(none) ~]# scp ''user''@host:~/.ssh/id_rsa.pub .	+
-	[root@(none) ~]# cat id_rsa.pub >> ~/.ssh/authorized_keys	+
-	Substitute <tt>''user''</tt> with your user name on the host of course, and do this for each user you want to have access on your simulated machine.	+
-	To make this changes persistent, sync your simulated disk:	+
-	press Ctrl-c in the simulator tcl shell window to obtain the prompt, and then type:	+
-	% mysim bogus disk sync 0	+
-	You can resume the simulator typing	+
-	% mysim go	+
-	Now, ssh should work: at your host prompt, type	+
-	$ ssh root@172.20.0.2	+
-	If everything went well, it should ask you no password, and take you to the simulator prompt.	+

reldomacc This article explains how to setup ssh your host and your simulated environment. At the end, you will be able to run ssh to connect to your host from the simulated environment, and viceversa. This information can be (partially) found on the IBM system simulator user guide (on a default sdk installation, this can be found on /opt/ibm/systemsim-cell/doc/SystemSim.Users.guide)

The following conventions will be used:

• $ your user bash prompt in the host environment
• # your root bash prompt in the host environment
• [root@(none) ~]# The bash prompt in the simulated environment
• % The TCL simulator shell.
