If you are a guest, you can apply for a [guest u:account](https://zid.univie.ac.at/uaccount/#c11096). This will give you access to eduroam and to the VPN. Your application needs to be endorsed by a staff member, who also determines the expiration date of the account.
+### Connect Script
+If you are using a terminal (Mac, Linux, WSL, ...) you can use the script [connect2jet.sh](connect2jet.sh) like this:
+```bash
+connect2jet.sh -g [U:Account-Username]@login.univie.ac.at [Jet-Username]@jet01.img.univie.ac.at
+```
+There is also an option to forward a port, e.g. the VNC Port:
+```bash
+connect2jet.sh -g [U:Account-Username]@login.univie.ac.at -p 5901 [Jet-Username]@jet01.img.univie.ac.at
+```
+which allows you to connect to `localhost:5901` and view the VNC session. Other gateway servers can be `srvx1.img.univie.ac.at`
+
## VNC
**Be aware! Everyone with the VNC password will get access to your account**
