System admin for the BRICCS infrastructure

BRICCS page in the RCS wiki : ​https://rcs-manage-1.star.le.ac.uk/wiki/index.php5/BRICCS

A list of the systems we have available, and what software they are running.

Hospital systems

On the hospital side, the machines are created within the UHL server facility managed by IM&T. We currently have four VMs, visible only from within the hospital environment.

Mail: System needs to be able to manage local and outgoing mail. 'smarthost' used for everything else: smtp.xuhl-tr.nhs.uk

ClamAV: Put the following in cron.weekly and chmod 755: clamscan -ri --exclude-dir=/sys\|/proc\|/dev / | mail -s "ClamAV Scan Results for date +%D" email@…

All UHL machines need to be able to access the internet for updates, etc. For this they need to be 'allowed by rule' through the BlueCoat firewall. This is arranged by UHL IM&T (Geoff Harrison)
