unable to connect with VM after rebooting

[Gandhimathi Velusamy]

Hi,

My user name is gandhima and I am having  emulab account. I am working on Protogeni using Flack. My slice name is 'distlinc' and I gave reboot command on two VMs pc255.emulab.net:32314(host 1) and pc255.emulab.net:32315 (host 2). After that I am able to connect with pc255.emulab.net:32315( host 2) via putty. But I am not able to connect with pc255.emulab.net:32314(host 1). I am getting network error and connection timed out. It seems it is not up. Could you please, help me to connect with host 1.

Thanks

Gandhimathi

Hi Gandhima,

Are you able to ping your host2 from host1? That will tell you if host
2 failed to reboot or if it something else that is causing you not to be
able to ssh into host 2.

If you are able to ping host2 from host1, you can try ssh'ing to host 2
via host 1. To do so, first ssh into host 1 using the command:
ssh -A -i <pathToPrivateKey> -p 32314 <username>@pc255.emulab.net
And then from inside host1 do:
ssh host2

If this fails, all I can suggest is to try again with two other VMs.
Only somebody from the protogeni development/operations group at Utah
can check to see why you are unable to connect to your host2. Given it
is the holidays, I don't know if anybody there will be able to help you
in a timely manner.

Best wishes,

Hi Vic Thomas,

    Thanks for your suggestion. I tried to ssh from host2 to host1 but it didn't work. 

"host2:~% ssh -A -i /users/gandhima/new_geni_ppk.ppk -p 32314 gand...@pc255.emulab.net

ssh: connect to host pc255.emulab.net port 32314: Connection refused"

I will try with new slice. 

Wish you a Happy New Year!

Thanks 

Gandhimathi

Hi Gandhimathi,

It appears you are running the ssh command from inside host2. You
should run the command from your laptop. If the ssh is successful, you
will be logged into host2. Then, from host2, you can "ssh host1".

Before you try to ssh into host1 from host2, make sure you are able to
ping host1 from host2.
