Network is unreachable & connection time out

[Xusheng Ai]

Hello,

I am working on access FABRIC VM slivers using the bastion host from Jupyter Hub, following by https://learn.fabric-testbed.net/knowledge-base/logging-into-fabric-vms/#ssh-keypair-primer-creating-identifying-fingerprinting-keypairs.

I tried to access slivers
ssh -F ~/work/.ssh/fabric-ssh-config -i ~/work/.ssh/sliver_key_pair ubuntu@11.22.33.44
It shows error:
channel 0: open failed: connect failed: connection timed out

In addition, when I tried
ssh -F ~/work/.ssh/fabric-ssh-config centos@1.2.3.4
It shows error:
channel 0: open failed: connect failed: Connection timed out

I’not sure where the problem is. If you could help me with that, I will much appreciate your help.

FYI
cat fabric-ssh-config

UserKnownHostsFile /dev/null
StrictHostKeyChecking no
ServerAliveInterval 120

Host bastion-?.fabric-testbed.net
User xai_0051546236
ForwardAgent yes
Hostname %h
IdentityFile ~/work/.ssh/id_rsa_fabric
IdentitiesOnly yes

Host * !bastion-?.fabric-testbed.net
ProxyJump xai_0051546236@bastion-1.fabric-testbed.net:22
##ProxyJump xai_0051546236@bastion-2.fabric-testbed.net:22

Thanks,
Xusheng

The IPs you are trying are not your VMs. Those were examples mentioned in the documentation. You should replace those with the IPs you obtain after creating your VMs

Thank you so much for the clarification
