access jail via ssh

[dirkme]

I googled around and tried some things, so far:

I started ssh with the jail shell with:

Code:

service sshd onestart

only because I have no idea how to access /etc/rc.conf. nano isn't
installed etc. however.

When i try to ssh into my jail, lets say:

Code:

ssh: root@192.168.1.5

I get asked for the root password but the system root password doesn't get accepted.

so, i just can't access the jail via ssh to install radarr and nzbget.

Help ;-)

SSH into you main system and then switch to the jail you want and install.

nano isn't installed etc.

ee probably is, or you can always pkg install nano. But in any case, as @Jailer said, there's no need to ssh in to the jail. Just ssh in to the root account on your FreeNAS box, jls, find the number of the jail you want to access, jexec # tcsh.

How do you switch to a jail?

I changed root password with the jail shell, but still can't ssh into the jail, i am interested in the way to ssh as root and switch to jail

In addition to what has already been mentioned, the behavior you noticed is because SSH root logins are disabled by default in FreeBSD jails. The recommended method is to create a user as described in http://doc.freenas.org/11/jails.html#accessing-a-jail-using-ssh.

You just quoted me telling you exactly how to do this.

I switched it on and can ssh to freenas. I also can ssh to the jail IP but root password is not accepted.

You seem to be missing the responses to your questions.
To ssh directly into the jail you need to allow root access via ssh in the jail. To do that you need to edit the /etc/ssh/sshd_config file and change the

Code:

PermitRootLogin

to YES. Also you need to edit the /etc/rc.conf file and change

Code:

service_sshd

to YES.
You want to change the rc.conf file so that ssh starts with the jail rather than having to start it manually every time.

 

[danb35]

...or do what @dlavigne recommended, create a new user within the jail, and ssh in as that user. Then su to root as necessary.

I did all of this in the jail and ssh is now working just fine, the root password still gets denied.

I want to use midnight commander to ssh over to the jail and drop some files there. Is there a way to root to freenas and move files from there to the jail with midnight commander?

Did you give the jail's root user a password? The freeNAS root user's password is not passed through to the jail's root user.

Yes, I used

Code:

passwd root

added my password twice, but still doesn't get accepted at ssh.

Okay, in the /etc/ssh/sshd_config file there is another line you may need to edit. PasswordAuthentication should say yes.

Code:

PasswordAuthentication yes

PasswordAuthentication yes

did it and still get this: Permission denied

Update: I installed in the jail MC and can now ssh into a different computer and pull my programs from there. At least i can get files into the jail. But i really do not understand (except it is a bug) why I can not ssh to the jail as root having all the settings right.

You can youre just not getting it right yet.

Ok, if you type some step by step for dummies, I am more than happy to try until we succeed.

What are you using to SSH into the jail? EXACTLY what all changes did you make to the /etc/ssh/sshd_config file?

Can't do it tonight, but asap i have a few minutes I will type it down.

From memory:

changed root password

PasswordAuthentication="yes"

PermitRootLogin="yes"

service_sshd="yes"

That should cover it, but i make sure it is all set as I wrote it.

Did you un comment the lines you modified? You have to remove the pound sign # at the beginning of the line to un comment it and make it active.
