Please send a snapshot that shows the code in the cell not just the output.

[Ilya Baldin]

Can you please send the screenshot of the entire cell and its output that submits the slice and reports the slice status?

Does this cell actually complete its execution (i.e. the asterisk in the square brackets next to the cell is cleared)?

When you inserted the code I showed above did you update or set the slice_name variable to be the name of your slice before you executed it?

In the calendar widget you do not appear to have selected a new expiration date.

Hello,

Please inspect your application configuration or try to add debugging output – since this is your custom application we can only provide limited assistance. If a slice is operating as expected at the Operating System level the rest is generally considered experimenter’s responsibility.

[Ilya Baldin]

For renewing slice in the portal can you please send a screenshot of the calendar widget in the slice view after you selected the new renew date but before you click ‘Extend’.

Your slice is up and running – all VMs and services are up. Please verify that the network interfaces exist under the names you expect in all the VMs. We generally cannot help you with your custom application, but the error suggests the application is trying to use a network interface that for some reason is not there or is not in the ‘up’ state. Please validate the low level functionality of the slice (e.g. the node reachability) before starting your application.

[Ilya Baldin]

I suspect you are not letting the script complete. I can see in the console that your slice is up and all VMs are there and running.

You may want to add a cell that executes the following after the cell you showed in the screenshot:

slice = fablib.get_slice(name=slice_name)
slice.show()
slice.list_nodes()
slice.list_networks()

Please send us the outputs of these commands.

[Ilya Baldin]

Also, the styler warning you show above is harmless – whatever is going on with the slice has nothing to do with that.

We have been informed that a large number of identity providers have been added back into CILogon, if you were from one of the affected institution in the .br TLD, please try your institutional login.

InCommon confirms that there is a problem with the CAFe federation metadata, resulting in all Brazilian IdPs being dropped from eduGAIN (and thus InCommon). The eduGAIN staff are working to understand the problem on the CAFe federation side and the plan to fix it. Currently there is no ETA on a fix.

Please contact your instructor for any questions regarding assignments.

Please in the future direct your questions to your class instructor.

1. You are confusing a public SSH key with the private SSH key – your configuration should point to the private bastion key SSH key
2. You can change the configuration by re-executing ‘Configure your environment’ notebook while updating the values in the appropriate cells of the notebook:

First cell of the notebook:

# your bastion login can be found in your profile page. Remember to omit the < and > when pasting into this
export FABRIC_BASTION_USERNAME='<YOUR_BASTION_USERNAME>'
# the ID of your chosen project. You can change this value any time you change the project. Remember to omit < and >
export FABRIC_PROJECT_ID='<YOUR_PROJECT_ID>'
# check the file name under which you uploaded your bastion private key file into and change this variable from fabric_bastion_key_file_name to its actual name
export FABRIC_BASTION_PRIVATE_KEY_LOCATION=${HOME}/work/fabric_config/fabric_bastion_key_file_name

Moving to educator support forum. In general it is the responsibility of the instructor or TA to provide support with class assignments.

Please direct your questions to your class instructor. We do not provide support for class assignments.
