Scripting was a weak point of SMB devices until firmware version R77.20.80: You can easily perform scripted tasks after each boot process (see sk52520 How to run commands at boot on an SG80/600/700/1100/1400/1200R -- UserScript for details), but no cron job was possible as crond did not run in GAiA Embedded (although the command crontab exists, it was unusable). There was a procedure to enable crond (Spikefish Solutions Blog: Enabling cron, the scheduling service on 600 / 700 / 1100 / 1200R) if really needed. Since R77.20.80, crond is running, see the details in R77.20.80, cpdiag and crond.
But e.g. to issue a scripted reboot every two weeks at a certain time, we can also trigger the script over a SSH connection from another device. Details can be found in sk106836 How to configure SSH authentication using RSA key files on Security Gateway 80 / 600 / 700 / 1100 / 1200R/1400 appliance. Remember to keep the passphrase empty when generating the key pair ! First step is to run # bashUser on while in expert mode to enable login directly into expert mode and WinSCP access. On the SMB box, we then create the file /pfrm2.0/etc/myreb.sh :
date >> /pfrm2.0/etc/lastReboot
(echo y ) | reboot
On the unit that shall issue the command (based on GAiA or Unix) we follow sk95890 How to configure SSH authentication on Gaia OS using RSA key files and create /home/admin/sshreb.sh :
ssh -i /home/admin/MyKey ip.x.x.x sh -l ./pfrm2.0/etc/myreb.sh
After first connect per ssh, the script is able to login and perform reboot automatically after being called using cron. This is easy e.g. on a Gaia device (in GAiA WebGUI, see under System Management > Job Scheduler). Such a script can also perform TP Updates automatically, but at different scheduled times for each blade using the online_update_cmd !
