Bellovin, Jason Nieh Email privacy is of crucial importance. Existing email encryption approaches are comprehensive but seldom used due to their complexity and inconvenience.

A debate on the reliability of memory and types of memory failure

High Availability, Failover protection Introduction In a production system you want to be able to do planned maintenance: Machines may crash, so a mechanism for automatically handling this is required too.

Redundancy of services on the realservers is one of the useful features of LVS. The most common problem found is loss of network access or extreme slowdown or DoS. Hardware failure or an OS crash on unix is less likely.

Spinning media disks fail near the end of the warrantee period in my experience - you should replace your disks preemptively. The director s don't need hard disks. I've run my director from 30M of files including perl and full glibc pulled from my Slackware distribution.

Presumably a mini Linux distribution would be even smaller.

Background: What is BBST

Reconfiguring services on the fly with ipvsadm will not interrupt current sessions. You can reasonably expect your director to stay up for a long time without crashing and will not need to be brought down for servicing any more than any other diskless router. An alternative to flash memory is a cdrom "Matthew S.

CD based if it gets compromised I just reboot it. The LVS code itself does not provide high availability. Other software is used in conjunction with LVS to provide high availability i.

Several families of tools are available to automatically handle failout for LVS. Conceptually they are a separate layer to LVS.

Some separately setup LVS and the monitoring layer. Others will setup LVS for you and administratively the two layers are not separable. Here's an article on the high cost of delivering high uptime computer service by Steve Levin.

The author says that NASA runs on three 9's For this level of reliability, the system has to handle all faults without human intervention. There are two types of failures with an LVS.Started in by the Dark Tangent, DEFCON is the world's longest running and largest underground hacking conference.

Hackers, corporate IT professionals, and three letter government agencies all converge on Las Vegas every summer to absorb cutting edge hacking research from the most brilliant minds in the world and test their skills in contests of hacking might.

As a follow-up to Tuesday’s post about the majority-minority public schools in Oslo, the following brief account reports the latest statistics on the cultural enrichment of schools in Austria. Vienna is the most fully enriched location, and seems to be in roughly the same situation as Oslo.
