System admin for the BRICCS infrastructure

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

Hospital systems

On the hospital side, the servers are Virtual Machines created within the UHL data centre facility managed by IM&T. We currently have nine VMs, visible only from within the hospital environment. One of them (uhlbriccsex01) has an external facing address for client access.

In addition we have two laptops with server software - running Ubuntu on VMWare Player to allow for REDCap to be delivered in a stand-alone mode for use initially in the GRAPHIC 2 study. More information is on the study page.

  • 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 for VMs in the data centre, Bradley Wright for the laptops / desktop machines).

JLMVLX1

  • Hostname : JLMVLX1.xuhl-tr.nhs.uk

    • Packages: phpmyadmin mysql perl openssl webmin.deb open-vm-tools open-vm-toolbox

On the Windows host machine, the 'all users' start menu has a shortcut to REDCap, and the 'default applications' item is removed. A batch file 'startup.bat' in the all users' startup applications folder triggers the starting of the VM.

The batch file to close the VM only works for me, not for Sue. Is this a firewall issue? I've set the network (using the Local Security Policy) to be private, and that didn't help. Andy Carruthers suggests setting other users to 'power user' status (or failing that, 'local administrator' status) and seeing if that gives them enough rights to shutdown the VMs. If it does, that is an acceptable solution, given that it's only a couple of users and a couple of laptops. On testing power user is not sufficient, but local admin is. Caroline Hughes is processing applications for local admin status.

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 or mod_proxy_ajp to pass the request to JBoss on 8080. JBoss works natively.

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?
