I'm looking for a snmp server for windows, are there any free (or at least working trial version) ones, I can only find clients?
I know I could install the windows snmp service but here at work it is not really an option (I don't have the "win xp" CD needed and support is as complicated as slow, even worse, it's Friday).
Thanks!
The Net-SNMP software contains both clients and servers. Specifically, the project contains both an SNMP agent server than runs on windows, as well as a trap receiver application as well.

I Want to know if Windows CE 7.0 has same API and functionality with normal Windows system programming.
For example, i have to deal with serial(RS-232), TCP/IP, select() and so on in Windows CE 7.0.
Can i use all of API same as normal Windows?
Or there are some Difference between them ?
The API are similar, but you should expect some differences.
For example serial port drivers may not support asynchronous read/writes. This is supported in the OS (since ver 7.0), but I have seen no drivers actually using it.
Also socket API is similar but, as you know, evil hides in details.
As a general rule you can't take for granted that software running on Windows desktop (or "normal" if you prefer :)) will just need a rebuild to run on CE.
It will need at least a rebuild (and sometimes this may be clumsy if you are using different releases of Visual Studio).
I have a piece of software written "out there" (e.g. no source code available) that allows me to use it in multicast mode. I'm trying to use this software on a network that, for technical reasons, can only use IGMP Version 2.
My OS is Windows 7 (64-bit, though I doubt that makes a difference). So far my searches have only given me Windows XP & Windows Server solutions, all of which involve editing the registry. In addition to the usual reasons (aka "registry paranoia"), I hesitate to edit the registry in this case because this particular network is not the only one that I will be using; I have not problems at all in all the other networks I try using multicast on.
Is there a straightforward way to force this software onto IGMP V2?
Thanks!

As far as I remember, adding IGMPVersion=3 to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters is the only way to solve your problem.
Anyway, there is another creepy solution - just write a little daemon, that will sniff for IGMPv3, parse data from it and send IGMPv2 packets =)
I need to write an app on Mac OS X that would send remote command to Windows applications to perform some tasks. The computers will be sitting on the same subnet and the Mac and Windows computers all have a fixed IP.
The data sent over really are just some string or boolean parameters so that the Windows app can perform specific tasks.
Someone will be writing the Windows app and I will be writing the Mac app.
I can find in the developer's doc about Mac to Mac communication, but nothing about what I need.
What's the best way to achieve this? What protocol is best suited for this?
Take a look at the Bonjour SDk for Mac and Windows: http://developer.apple.com/opensource/
There are (at least) two separate problems here:
#1 is how you discover the other app. Bonjour is one possibility, as is a local broadcast, as is explicitly configuring the hostname of the peer
#2 is how you talk to the other machine once you find it. For that part, I would suggest:
a) use TCP instead of UDP (in most cases), so you don't have to worry about retransmissions & sequencing
b) rather than inventing your own client-server protocol on top of TCP, use an existing one. I hear there's something called "HTTP" that's starting to catch on...
Could you just use UDP to broadcast a message out to the network? Your apps (regardless of whether they are running on Mac or Windows) can listen for the message and process them as needed.
I need a virtual server for web development, it'll host Apache+Postgres+Ruby+something else.
What's the most effective software to run such a server? (ie with least virtualization overhead)
Is there a way to run Linux as as service?
I use VirtualBox at the moment, but it's inconvenient in some ways, such as it needs an emulator window open which also captures keyboard input when alttabbed into.
(Also, coLinux hangs at boot on my machine, so it's probably not an option)
Check out the features of VMWare Server. It's free, you just have to register.
I've never found VMware to be much of a performance hog unless running 3+ virtual machines.
The latest free server version (VMware Server 2) runs as a service IIRC, so you can set up your dev server to start up and shut down when your PC does, and you can either log on to the VM's console through the web interface, or create a shortcut on your desktop so it's fairly non-obtrusive.
There is a very convenient utility that hides VirtualBox from the foreground completely: vboxctrl. With vboxctrl you can run a Linux server on your Windows machine, make it automatically go to sleep when Windows shuts down or hibernates; then use any SSH client to log in to the server. Or you can use Xming to open graphical windows from the Linux server; I've worked quite a lot of time in GVim open through Xming.
If anyone needs more details, leave a comment, I may write an article about this.
I'm used to running my own DJB dnscache on all unix-like systems I have, i.e. Linux and Mac OSX. Now that I got me a Vista, I wonder what can I run on it to the same effect?
Windows already has a service (DNS Client) that caches dns requests.
Built-in DNS servers are considered server functionality in the Windows world. On Vista, you'll need to get a third-party DNS server. After that, it's as simple as setting your DNS server entry to 127.0.0.1 in your TCP/IP settings.
A quick Google search found SimpleDNS, but I've never used it and can't attest to how well it works.
The defacto most popular BIND software runs on Windows, as do many other DNS servers.
There's also experimental versions of Unbound for Windows available from here. Unix versions of Unbound have been available since last year and are already in production use in many ISPs.
The author of Unbound is looking for beta testers for these experimental versions. If you try Unbound and find any problems please report them at http://www.nlnetlabs.nl/bugs/
