Worried about bed bugs in your hotel room?
Before booking a hotel room, you may want to read user reviews of the particular hotel and location — frequently, guests who’ve had bug problems report them online. Bear in mind that a report about one hotel does not mean the issue wasn’t isolated to one room, or that hotel management hasn’t since exterminated.
Still concerned? Concerned travelers may want to check their bed for telltale signs of the bugs, a more common practice years ago. Before jumping into bed, here are a few spot check tips:
TCP connection established using Firewall client may close unexpectedly
Firewall Client software uses a control channel for communication between the Firewall client and ISA Server (UDP or TCP port 1745). If a client application wants to connect to an external computer on TCP port 23 (i.e. telnet protocol) , the control channel is used to negotiate a new dynamic port for this specific traffic (after ISA rule verification, of course). After this negotiation, telnet traffic goes through the above negotiated port. Let’s call this the data connection.
Now, what happens to the control channel TCP connection? It is left open until one of the peers closes the data connection.
To leave the control channel open, the Firewall client has to periodically send a KeepAlive packet to ISA Server. This is done by the Firewall client every 10 minutes. If a device between the client and ISA Server has an idle connection timeout configured for less than 10 Minutes, then this device will force the closing of the control channel, with the result that ISA Server and the firewall client drop the data connection shortly thereafter (depending on the third party device timeout value).
To correct this behavior always ensure that the third party device has an idle timeout greater than 10 minutes.

Talking about NEWS: eWeek – “Is VMWare a dead duck?”
Looks like Steven J. Vaughan-Nichols from eWeek sees the writing on the walls.
Is VMWare a Dead Duck?
Microsoft, Red Hat, Citrix, Novell and now Oracle are all offering free or open-source virtualization of one sort or another. Can VMware survive?
http://www.eweek.com/article2/0,1895,2216435,00.aspThis market space is evolving so rapidly. Why would any company ‘bet the farm’ on one virtualization technology and rush into virtualizing their infrastructure when this technology hasn’t matured yet? Buying virtualization products today is like buying a car in a town where there’s only one car dealership. All the cars sold are bare bones Chevrolet Pick-up trucks and everything sold is an additional nickel-and-dime option that you have to pay for.
Meanwhile look at the "new dealerships" that are opening up just over the horizon:
- Microsoft’s Hyper-V
Microsoft’s virtualization hypervisor has a negligible cost associated with it while providing better performance than traditional virtualization technologies. Additionally, it’s compatibility with all Windows Server hardware platforms make it the easy choice for customers looking to virtualize their datacenter on the hardware that they’ve already chosen – as opposed to being forced to purchase specific servers in which VMWare has developed drivers for.
Because VMWare has it’s own proprietary driver model, you can not use Windows drivers for VMWare ESX – it requires that a custom driver be available for the hardware platform you are to virtualize on.
…meanwhile all servers that support Windows Server can leverage Hyper-V.- XenSource
Open Source virtualization has collaborated to standardize with Microsoft on a set of virtualization formats and interfaces to insure management tool interoperability and performance making XenSource a perfect solution for traditional "UNIX shops".- Virtualization-on-hardware
Intel & AMD are all working on virtualization-done-in-hardware where all virtualization operations are handled in a chip. This is a magnitude of power greater than today’s piddly "VT" technologies that are in today’s processors which simply assist virtualization software. How long before the entire market of core virtualization software rendered moot?IT Managers that decide against rushing into this market just so that they can "virtualize their datacenter" regardless of the costs of doing so and regardless of how the market evolves toward a low-to-no cost virtualization technology strategy will find themselves poised as visionaries and keen strategists in comparison to those that rushed to implement a virtualization architecture.
The cost of virtualization software will be one of the first things people consider cutting when they look at cost mitigation within IT.
