The company I work with currently has 10 windows boxes running various in house scripts, however occasionally one goes down and no one notices for periods of up to 24 hours because the data that is manufactured is only gathered on weekly intervals. Does anyone know of a management system that will notify when a box goes down and possibly shoot uptime and response statistics back to a web management system on a linux box?
There are many.
I use Nagios for monitoring Windows and Linux servers. You might also look into Zenoss. Both are open source.
http://www.pingdom.com/ is simple to use and you get a 30 day trial - 9.95 a month gets you a lot if you decide to sign on. have it for all my apps
I would have a bash script call ping on the machines and email me (or whomever is responsible) when a box goes down.
I've seen IPMonitor in use, and it is a very good tool (but expensive). Nagios is a free alternative, and it's supposed to be quite good, but I've never used it myself.
I know nmap has a way of showing you the machine's uptime when you use the OS fingerprinting option.

I am anticipating multiple projects in Linux in the near future. I believe I am going buy a new, fast development laptop and was thinking about running Linux natively on the box for speed reasons (I usually run Linux in a VM on a Windows box).
However, I have been juggling with the idea of continuing to work with Linux in virtual environments, one VM per project. It seems to have the upside of environment isolation as well as strong portability. The downsides seem to be speed (since I am not running the OS natively) and isolation of some resources I would like to be common (let's say Pidgin, where I want to access common logs or something).
Are people doing this? What else is there to consider? Any insight would be great. Thanks.
Going with Preet's answer: As I always say..... unless you have a issue - don't optimise, and then first throw more hardware at it....In other words - why not try it. A linux host is likely to be very fast host for virtual machines. – Preet Sangha

I'm trying to implement a socket listener in Windows Phone 7.1, which should process the incoming data and make some actions based on it (constantly, without interrupting). As far as I've found this, the info described there confused a lot, so these are the questions:
Is there some ability for the background agent to be run constantly, without interrupting by the system (or with acceptable amount of running time, more than 10 minutes)?
Is there any API to communicate with running agent, something like Android's AIDL?
PS. I cannot use Push Notifications.
No, background agents cannot run constantly. If you need code to execute constantly then you should keep the app running, maybe enable running under lock screen if appropriate.
No, you cannot connect to an agent.
Agents are not like services.
Your sockets requirement sounds like you will run into the same problem presented by this question: Windows Phone 7 (Mango) App gets disconnected when put in background?
PeriodTask is only executed every 30 minutes or so and thus cannot maintain a socket connection. You might want to look into running under the lock screen, as per Matt's answer, or perhaps ResourceIntensiveTask which can run for as long as you want for 10 minutes but only while the phone is connected to power and the phone has > 90% battery.
There is no API to communicate between the two but applications and their tasks share isolated storage, including databases.

First and foremost, I would like to say I am very, /very/ new to programming and the like. If I decide to build this, this would probably be my first "large" project i've ever done myself.
What I am looking to build is a very simple Chat/IM client to use for the users in our office network. It would just call us their Windows logon name and use that to IM and the like. I'm talking a very simple client, with a list of names of people who are logged into the network, and option to IM them and an option to do a multiple user chat. It doesn't have to be visually stunning.
How difficult would this honestly be? Is it possible for me, someone who has very little knowledge when it comes to programming to teach myself how to build it?
If not, can you explain why this would be very difficult and what already built clients would work well for what I am using?
This is a big application. Your first parts will suck and refactoring it later will suck even more. I suggest building something small in the first place and then step from one bigger project to another.
XMPP/Jabber is IMHO the best solution for office IM. Most clients like Pidgin, Adium etc can connect to it. Every bigger company I worked for in the last years used it. Take a look at Openfire - A free open source XMPP server that you can directly connect on and which is easy to set up: http://www.igniterealtime.org/projects/openfire/

Hello friends can anyone suggest me a Net Monitor for Employees tat allows you to see screens of computers connected to the network. This way you can observe what your employees are doing! Additionally, you have the ability to take control of a remote computer by controlling the mouse and keyboard. You can record remote computers screens even when you are not monitoring them. When your employees need instructions, you can show them your desktop. To increase your efficiency the console now include several tolls that can be executed on all or just selected remote computers. When you need attention you can send a message to employees and/or lock the remote computer. Communication uses encryption. Application works through Internet, LAN, WLAN or VPN. Agent can be remotely installed.
i am runnin a traing institute with 30 Pcs which uses windows Xp and i am lookin for commercial software..
Seem like a puzzle of regular vnc software should do the job (recording comes separate, you may need r-vnc too), but vnc tends to be slow outside of LAN.

has anyone having problem with latest release of arcgis 10?
my services running on ags 10 is very slower than 9.3.1.
And Arcgis Desktop is Really slow which cause me to downgrade back to 9.3.1.
Is it just me or anyone else having issues like this?
This "upgrade" from 9.3.1 to 10 is not worth it. I have a very new machine with fast processors and video cards and 10 runs much much slower. Just creating a simple buffer takes around 2 minutes where in 9.3.1 it would finish in about 10seconds. Unacceptable...
We just switched over to Arc 10 a couple of days before service pack 1 came out. We had some serious issues including speed problems with ArcGIS Server, Image Server and IMS. We applied the service pack and it took care of most of our issues on the servers.
We have not applied SP1 to the desktops or ArcSDE since we are limited by 3rd party tools that need to be tested first. But I am hoping that the problems we still see on the desktops hitting SDE will be resolved once we can apply SP1 there as well.
I have had arc 10 since September. Its been the worst experience of my professional career. Besides the crashes or lock ups 3 to 4 times per day, sometimes much more, it is the slowest program I have ever had the displeasure of dealing with. I have a brand new machine with up to date video card and 16 GB of memory and it still takes longer to do the simplest tasks that I don't see how they can stay in business if this is the norm. HORRIBLE HORRIBLE Exp. I would not recommend this to anyone. If there is another option besides arc I would definitely go with that.
I haven't had any problems with Arcgis 10. However please note that the system requirements for ArcGIS 10 are much higher than ArcGIS 9.3.1
What are your hardware & software specifications? Do they meet the minimum requirements?
