SSH Login Issue with Client

[Sepideh Academic]

Dear Fabric Committee,

I have set up multiple servers and a client within a Fabric slice, distributed across different sites. I ensure that my slice is consistently updated. While I can successfully log in to my servers via SSH, I am unable to access the client. Interestingly, I am able to ping the client from my servers and receive responses, but SSH access fails with the following error:

816:3eff:fea8:c024
Warning: Permanently added ‘bastion.fabric-testbed.net’ (ED25519) to the list of known hosts.
channel 0: open failed: connect failed: No route to host
stdio forwarding failed
kex_exchange_identification: Connection closed by remote host
Connection closed by UNKNOWN port 65535

I would appreciate if you could guide me.

Hi Sepideh,

Is this still an issue? If so, could you please share your slice ID?

Also, this may happen because of expired bastion keys. Could you please run the notebook:  jupyter_examples-rel1.7.1/configure_and_validate.ipynb ? This notebook will renew your keys if the keys are expired.

Please let us know if this helped.

Thanks,

Komal
