You can also forward your ssh-agent through the ssh connections that you make so that you don’t need to copy your private key off of your laptop

“Derek, don’t be such a pahole”

Take a look at ssh-agent. You do need to enter your passphrase one time to ‘unlock’ your ssh key but then future connections are password less.

Please please please set passphrases on private ssh keys. Any administrator of a system that your ssh key resides on can use your private key.

Gotcha, thanks for the explanation

Forgive me for not knowing what CSP stands for, could you help me out?

#HPC

Practically, I’ve used a shared IB network to pivot between systems that I did not have logical access to, but that did have a shared Lustre filesystem.

Solid question. I consider IB to be a layer 2 network without many of the segmentation tools that IP routing gets you. Once you set up RDMA, you also lose most abilities to monitor and control traffic over that channel

How about a fun #HPC #CyberSecurity relevant discussion? We came out with some guidance mid 2024 for #riskmanagement folks that I encourage everyone to read. csrc.nist.gov/pubs/sp/800/...

Oh that’s neat, I didn’t realize that. I’m assuming that there is negligible hypervisor overhead?

Yeah. I hear that, especially for scientific codes. For things like drivers and system services I think memory safety is worth the hassle.

They may be geeky, but they’re a crucial if not very visible part to our day to day lives. Weather forecasting is a big one as well as industrial uses like development of complicated stuff like more cost efficient jet engines and new medicines.

And a lot of non-nerds too, it turns out

Is that just the memory safeness talking or are there other issues with rust that you could elaborate on?
