MRD

See run-test.sh for python-ismrmrd-server's invertcontrast demo:

MDR Server

pymrd.service (hard coded paths) runs and restarts the local MRD server using uv.

TODO: consider setting TMPDIR to shared location (/raidzeus/?)

Enabled like

sudo systemctl enable --system --now $PWD/pymrd.service

Scanner config

1. fire_identity/id_rsa.ppk should be copied to C:\Medcom\MriCustomer\ice\fire\
2. wip_1234b_fire_fire_mars_ssh.ini goes to %CustomerIceProgs%\fire\wip_fire_fire.ini (?)

wip_1234b_fire_fire_mars_ssh.ini was pulled from the msi installer WIP1234B_FIRE_VE11C_0809Wed_2021173520:./MriCustomer:./Ice:./fire:./.:n4/.:pkg/MrServers/.:MrVista/.:Config/IceConfigurators/.:fire/wip_1234b_fire_fire_mars_ssh.ini

Auth

Putty on windows scan console was used to generate rsa_id* (copied to /mnt/TWIX_RAID/Prisma1/Moon/FIRE/id_rsa*; 2025/11/17).

Note

at least for syngo MR E11

• rsa_id should be generated with -b 2048 not -b 4096 as documented!
• Host key for ini is RSA not ED25519 as documented!

See fire_identity/Makefile.

• fire_identity/id_rsa.ppk is the private key to be kept secret and only on the console computer
• fire_identity/id_rsa.pub is public pair and goes into ~/.ssh/authorized_keys for passwordless authentication

Host key is 4f:9d:13:00:78:dc:e0:25:7f:37:fb:7d:35:8e:65:08 and is specified in wip_1234b_fire_fire_mars_ssh.ini.
