titlepasswordless ssh to iana

You can modify your .ssh config to allow direct passwordless access from your device to iana, by adding this to your .ssh/config file on your end:

Host slac*
        User <you>

Host slacl
        Hostname s3dflogin.slac.stanford.edu

Host slacd
        Hostname iana
        ProxyJump slacl

and then add your e.g. ~/.ssh/id_rsa.pub from from your device to ~/.ssh/authorized_keys at SLAC, using:

ssh-copy-id <you>@s3dflogin.slac.stanford.edu

titleUsing cron

You can run cronjobs in S3DF. Users don't have to worry about token expiration like on AFS. Select one of the iana interactive nodes (and remember which one!) to run on.


Since crontab is per host (no trscrontab), if the node is reinstalled or removed, the crontab will be lost. It's probably best to save your crontab as a file in your home directory so that you can re-add your cronjobs if this happens:

crontab -l > ~/crontab.backup

Then to re-add the jobs back in:

crontab ~/crontab.backup
