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 eight VMs, visible only from within the hospital environment.

  • Standard packages: mailutils build-essential clamav htop fail2ban logwatch nagios3 chkrootkit snort make zip unzip apt-file python-software-properties
  • Mail setting 'Internet with smarthost': System needs to be able to manage local and outgoing mail. 'smarthost' used for everything else: smtp.xuhl-tr.nhs.uk - the server IPs then need adding to the UHL smtp whitelist. This is arranged by UHL IM&T (Paul Tracey).
  • ClamAV: Put the following in cron.weekly and chmod 755: 
#!/bin/bash
clamscan -ri --exclude-dir=^/sys\|^/proc\|^/dev / | mail -s "ClamAV Scan Results for `date +%D`" email@email.domain
  • 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)

University systems: LAMP Infrastructure

All systems on the University side should eventually run on LAMP insfrastructure. The systems are VM's provided by RCS.

In the case of the three CaTissue VMs, where the 'alias' is accessed over https, it is actually an alias for the LAMP Load Balancer run by RCS. The load balancer passes the requests to apache on the app server on port 80, and apache uses mod_proxy and mod_proxy_http to pass the request to JBoss on 8080. JBoss works natively.

Pre-LAMP University systems

The following are existing systems on the University side which have yet to be moved to the LAMP infrastructure. The systems are provided by RCS.

VBoxManage man page: ​http://www.virtualbox.org/manual/ch08.html

Note: when rebuilding a VM, the ssh key will change. On local machines use "ssh-keygen -R hostname" and "ssh-keygen -R IP" to remove them and then reconnect.

BRICCS Server Security

The following should be considered the standard specification for BRICCS Server Security:

ClamAV: Put the following in cron.weekly and chmod 755: 

#!\bin\bash
clamscan -ri --exclude-dir=^/sys\|^/proc\|^/dev / | mail -s "ClamAV Scan Results for `date +%D`" email@email.domain

fail2ban

logwatch

  • Note: By default logwatch mails daily reports to root@localhost - this probably isn't what we want. Configure /usr/share/logwatch/default.conf/logwatch.conf and alter the target address to someone who gives a damn.

NagiOS

chkrootkit

Snort

What else?

Note: See TracWiki for help on using the wiki.
