@JKrauska any update on zendesk ticket #9727 ? or could you add me to CC of that one please?

Dzahn triaged this task as High priority.Jan 22 2016, 8:29 PM

added you as a cc -- we can provide a older laptop this week.

Can we keep the laptop locked up in the IT den?

This means it will only be able to be accessed during normal office hours, but also means that there's less chance of it being stolen.

Yes please, that is what i wanted to ask for as well for the same reason.

I received a Thinkpad T420, WMF 389, from OIT (thanks!) and i'll install jessie on it next.

Dzahn added a comment.Feb 2 2016, 11:36 PM

I installed jessie on it. The hostname is : )

I wiped the disk with dd if=/dev/zero (one pass) before the install and disabled a couple things in BIOS,
like the fingerprint sensor that was enabled (also deleted fingerprint data), disabled flashing BIOS over LAN, disabled virtualization support, disabled other boot devices, disabled bluetooth .. and more

I think we should give you a SSD -- we have a few..

I would not want critical stuff running on a spinning drive -- and that drive is OLD.

A spinning disk can be securely wiped, where SSDs aren't really securely wiped in most instances. (Trim support is varied and not regularly applied across differing ssd vendors/models.)

I'm not sure a hdd is a bad thing in this regard; Unless we know the SSD can be securely wiped (doubtful), or if OIT/WMF is accepting that any issue with the laptop will mean the removal of the SSD by Operations for disposal/transfer rather than return to OIT.

Joel is correct that a newer SSD has a higher reliability than the older hdd.

i have given the laptop back to OIT today to keep it in their room behind the metal door for us and give ops members access when we need it

i put some sticky tape on it and wrote " Operations Team T123818".

i'll continue to work on it while at office

i need to update the pwstore with access info

yubihsm hardware plugged in and detected

installed the yhsm-tools package which provides

yhsm-keystore-unlock -- keystore unlock
yhsm-linux-add-entropy -- entropy seeder
yhsm-decrypt-aead -- decrypt AEADs
yhsm-generate-keys -- generate new AEADs

there is also the yhsm-validation-server and more but i did not install these (yet)

this also provided:

python-pyhsm (see

the example tool "" works and shows the device has a "power-up count" of 768.

@Muehlenhoff I've been thinking you should probably ask OIT for VPN access ( so that you can get into the office network and ssh to this laptop. makes sense?

or, alternative suggestion from ori ..

@Muehlenhoff let's talk about when we consider this one to be resolved. Technically the laptop and YubiHSM is there but i think you could not connect to it yet, right?

As discussed, I'll prepare the script and we'll do the actual setup/some tests at the offsite. Assigning to Daniel as a reminder to bring that laptop with him :-)

picked up from office. i also received 5 yubikeys from OIT (4 x yubikey4 and 1 x yubikey4nano) (zendesk Ticket #11781)

Dzahn added a comment.Oct 11 2016, 6:26 PM

we worked with it during the offsite. Moritz added a script to write the first 5 test keys and then we did. now some more testing is going to happen, and meanwhile my task here is to bring the laptop back to office.

Dzahn added a comment.Oct 30 2016, 4:05 AM

brought the laptop back to office in SF, on Thursday after metrics meeting, handed over to OIT
