Hi,

I installed a Debian VM through Marketplace, and also attached a network.
Then I added ssh key to the template, but I can not connect to VM with ssh.

[oneadmin @ bravo02 ~] $ ssh root@10.180.0.124
ssh: connect to host 10.180.0.124 port 22: No route to host

[oneadmin@bravo02 ~]$ onevm show 7

Can someone help me?

Thank you.

Your issue is not related to the SSH keys contextualization. There is a networking issue, and according to the error you receive when attempting a SSH connection, you have no routes declared for 10.180.0.0/24 network. Besides that, you should also check that br0 bridge on the compute node has an active network link attached.

Thank you, I’ll try to fix this.

Hi Sergio,

Now I’ve changed the network to 10.180.0.0/24 and now I can
make a ping connection to the VM.

[oneadmin@bravo02 ~]$ ping 10.180.0.124
PING 10.180.0.124 (10.180.0.124) 56(84) bytes of data.
64 bytes from 10.180.0.124: icmp_seq=1 ttl=64 time=0.319 ms
64 bytes from 10.180.0.124: icmp_seq=2 ttl=64 time=0.320 ms
64 bytes from 10.180.0.124: icmp_seq=3 ttl=64 time=0.301 ms

But the ssh connection does not work.

[oneadmin@bravo02 ~]$ ssh root@10.180.0.124
Permission denied (publickey,gssapi-keyex,gssapi-with-mic).

I put the ssh context.

EDITOR = vi oneuser update oneadmin

I also instantiated a new VM.

What’s the problem now?

Thank you.
