> Note: MONALISA_HOME would typically be used to specify a `local` installation. The value `install` can be used to have a default version downloaded and configured.
If it is required to run any shell command before starting either of the services, they can be added in `$HOME/.alien/config/CE.env` or `$HOME/.alien/config/ml.env`. Both files should typically contain a command to define the `X509_USER_PROXY` if needed for job submission by the JAliEn CE and which should then be monitored by MonALISA, for example as follows:

Both files should typically contain a command to define the `X509_USER_PROXY`**if needed** for job submission by the JAliEn CE and which should then be monitored by MonALISA, for example as follows:

export X509_USER_PROXY=$(ls -t /var/lib/vobox/alice/proxy_repository/*lcgadmin | sed q)
export MYPROXY_SERVER=myproxy.cern.ch # only needed for MonALISA
```
> Note: if the JAliEn CE does **not need** an X509 proxy, please ensure those variables are **not defined** for the services, to avoid false alarms in the VObox monitoring tests!
> Note: the JAliEn CE needs to have a valid `VObox token` to be able to submit jobs.
