I seem to have issues with registering an account on https://id.ucla-vast.com/ with my github account (jackl-xilinx) where it says it's sending a verify email request but I never received it at jackl@xilinx.com.

[dotkrnl]

Email address manually verified and access granted. Please see https://wiki.ucla-vast.com/books/cluster-user-guide/page/getting-started to get started.

@dotkrnl I seem to be having trouble connecting to cdsc0.cs.ucla.edu. Is the server up and running or am I locked out somehow? I am able to create a VM via ucla-vast but I can't connect to it via the browser or via ssh.

[dotkrnl]

The cdsc0.cs.ucla.edu server is up and running. You would need to use your username (jackl-xilinx) and your UCLA-VAST password as you set on the account creation process to login to that server, i.e. ssh -J jackl-xilinx@cdsc0.cs.ucla.edu jackl-xilinx@[ip] then enter your passwords.

If you failed to login three times, you will be blocked from future attempts for around half an hour. You can retry later or try on another IP address.

[dotkrnl]

From sudo lastb | grep jackl-xilinx I do not see your attempt. Please make sure that you have added jackl-xilinx@ before cdsc0.cs.ucla.edu

[jackl-xilinx]

Thanks. I tried again and I was able to connect using ssh -J jackl-xilinx@cdsc0.cs.ucla.edu jackl-xilinx@[ip] but when I killed that instance and created a new instance to run ubuntu 22.04, I wasn't able to connect back to the instance. I can connect to cdsc0.cs.ucla.edu but not the ip address of the VM instance. Can you see that instance or connect to it?

[jackl-xilinx]

I've killed the previous ubuntu22 instance now but the two instances i created afterwards with different configurations are stuck in deploy(4/4) state and I can't kill those.

[dotkrnl]

Seems to be some technical issues with the cluster right now. I am not working with UCLA VAST right now and I have directed the issue to our current administrator. If the issue is not solved, I will take care of it when I am free. Sorry for the delay and inconvience.

[jackl-xilinx]

No problem. I appreciate the response and your help with getting it working.

[dotkrnl]

Please try if you can use the instances now.
