Hi all, here are my few questions about freeBSD, they mostly concern Robustness, Security, Auditing and Support. These questions always apply to the standard packages of FreeBSD. Any additional sources can't be used in the target environment, where the Os is planed to be used. Robustness: - Does FreeBSD offer Load-Balancinglike Piranha, with the standard packages? This can be supported be clustering software or by dispatching service requests to different instances of the same server. -=09 - Does it offer Failover with the standard packages? This can be supported be clustering software or by dispatching service requests to different instances of the same server. -=09 - Is it possible to make a persistent image of the status of the running OS? This is needed to freeze the system and late continue computation with the same internal state. -=09 - Is it possible to set the maximum allowed system resources for any process? To support real time system, some kind of partitioning or resource ensurance is needed. Security: - What security mechanisms does free BSD offer on the network and data link layer? In target solution the security of the other layers (transport and application) are handled by the running applications and the middleware. - Availability, Acess Control and Integrity are important. What does FreeBSD offer to support these kinds of security? - Is there a way to ensure Non-repudiation on a FreeBSD system? The system is security critical and might handle credit card information and other data to identify persons. Is it possible to link this data to user action on the OS level? Auditing: - Are tools provided for browsing audit trails? - Are security violations automatically logged? - Is it possible to add custom monitors to the standard auditing? - Are tools provided to create from auditing trails custom reports? - Is it possible to audit all transaction of the system or specify what transaction to audit? Support: - Is there commercial developer support for freeBSD available? -=09 - Do freeBSD drivers for ARINC 429 exist? -=09 - Do freeBSD drivers for the CAN bus exist? -=09 - Do freeBSD drivers for ADFX exist? I hope that you can help me to answer these questions. I have read about freeBSD and was not able to find the answers I was looking for. It might be that I read any paragraphs concerning these topics in the manuals, but if that is the case I can't remember them anymore and would be glad if you can point me to these paragraphs.
