How To Enable Ssh In Solaris 11

Password less authentication may required in various setup and we need to configure password less authentication for root user in cluster setup in order to install cluster software on both the machine simultaneously. Here we will see how to configure password less authentication using ssh on Solaris nodes.

Extra – to enable SSH root login to zone: vi /etc/ssh/sshdconfig PermitRootLogin = yes. Vi /etc/default/login. CONSOLE =/dev/login console rolemod -K type=normal root. Svcadm disable ssh. Svcadm enable ssh. To delete a zone (NB There is no undo!) zoneadm -z zone1 halt. Zoneadm -z zone1 uninstall. Zonecfg -z zone1 delete. To restart ssh on Solaris 10 and Solaris 11, type the following command: sys1 # svcadm restart ssh From the source system (sys1), move the public key to a temporary file on the target system (sys2). Use the secure file transfer program. I'm using the commands below to enable SSH in order to use WINSCP to upload solaris 11.3 patches. It worked successfully on 2 LDoMS and failed to work on.

SSH as root on Solaris 11 05 December 2011 I needed to quickly enable SSH as root to rsync a load of data. Yes, I know there are far better ways to do it, and I know that enabling SSH for root is a bad idea, and lazy, and normally I’d agree, but I needed to do it. Anyway, it’s on a private lab network. To restart SSH in solaris you can use the svcs command to view the current status of the service root@solaris:# svcs grep ssh online. Computer How To How To, Tutorial, Example, Review.

Login to node1.

Create a new ssh keygen .Here i have used RSA keygen. If you want you can use DSA instead of RSA.

Go to the directory where the keys are stored. It will be stored in root’s home directory by default.

Now i am copying the rsa key to node2 as authorized_keys where you want to login without password. By doing this , i can login from node1 to node2 without password.

In node2,i am copying the rsa key to node1 as authorized_keys.By doing this , i can login from node2 to node1 without password.

How To Enable Ssh Linux

It is really easy to configure an NTP client on a plain standard Solaris 11 (that said it isn’t more difficult on Solaris 10 … it’s the same procedure). So i will just give a very short walkthrough.

At first you have to create a config file. You can edit /etc/inet/ntp.client, edit it and copy it to /etc/inet/ntp.conf

I’m prefering using 4 time servers. I think you could either use 1 or 4 ntp servers. Never use 2. And don’t use three, as when one fails, you have two time servers. And as i said, never use two. Why? An old saying goes: You never know how late it is when you have two clocks. I suggest reading the pool.ntp.org website for choosing a pool as there are continental and country-wide pools as well that may result in a more precise time. As Brian correctly stated in the comments, choosing a pool with servers containing only servers near you can really influence the precision of the time. So for example when you are living in the germany, you would use 0.de.pool.ntp.org for example, when you are living in the United states you would use 0.us.pool.ntp.org.

Now we add some additional configuration information. It’s more or less a copy of the stuff in /etc/inet/ntp.client:

As you surely know, the ntp daemon doesn’t synchronize time, when the time offset between time on the client and the time on the server is too large. So doing a ntpdate to initially force a time sync is a good idea:

Now we just have to enable ntp via SMF

And voila, one line has a *. NTP is starting to do it’s job:
