Hi,

I explored the JH notebook Wide Area Link (Layer 2), both the manual and automatic instructions. It seems I am having a bit of an issue running the commands there. With just this code:

from ipaddress import ip_address, IPv4Address, IPv6Address, IPv4Network, IPv6Network
import ipaddress

from fabrictestbed_extensions.fablib.fablib import FablibManager as fablib_manager

fablib = fablib_manager()

I am getting a TokenManagerException. I am not familiar with how fablib_manager() works, so I am unclear as to how to rectify this. Here is the exception trace:

TokenManagerException                     Traceback (most recent call last)
Cell In[2], line 6
      2 import ipaddress
      4 from fabrictestbed_extensions.fablib.fablib import FablibManager as fablib_manager
----> 6 fablib = fablib_manager()
      8 fablib.show_config();

Additionally, I have tried including the project id, but the same exception occurs:

project_id=”5c3d6ece-0af3-4277-a1a3-65300b8b9536″

fablib = fablib_manager(project_id=project_id)

Hi,

 

This is my Slice ID for the most recent slice where I tried site to site connection: 97872f32-3cc0-4843-bf91-636b71f4ee87 . The IP address seem to be configured. When SSHing into each VM, I am able to ping google but not the other VM. How can I establish connection between the VMs?

 

Thanks

Hi,

I was able to get the slice to be created, but do you have any suggestions to test the connection. I’ve tried pinging either VM with the connection, but this fails.

Thanks

I have tried SSHing from JupyterHub and the end of the log now has these new statements:
debug1: Remote: /home/rsinha8_0000056965/.ssh/authorized_keys:1: key options: agent-forwarding port-forwarding pty user-rc x11-forwarding

Unsure why connection is timing out.
