Control network: little tricks

Copying files to a local machine

file_copy_2022_DEC_20.zip

Using scp over multiple nodes is painful. This is a small script that does the job:

1. Log onto the control server using ssh with remote port forwarding:
   ssh smeuren@fastx3.slac.stanford.edu -Y -R 40000:localhost:40000
   ssh smeuren@mcclogin -Y -R 40000:localhost:40000
   ssh fphysics@facet-srv20  -Y -R 40000:localhost:40000
2. Start the script
   bash
   source $PACKAGE_TOP/anaconda/envs/python3.7env/bin/activate
   python3 ./smeuren/remote.py 40000
3. Open a different ssh connection to browse the file system, identify file you want to copy
4. Call the local script to download this file
   python3 local.py 40000 "/u1/facet/matlab/data/2022/2022-12/2022-12-17/ProfMon-CAMR_LI20_307-2022-12-17-180157.mat"
