I have made any perl scripts to survey my servers from a linux.
Of course, there are some of those on Wondows.
So, is anybody knows a command to survey a windows service from a linux.

Thanks.

Depends on what you want to do. If you just want to check simple things, like is a specific file available on the HTTP server, can you get a connection banner on the SMTP server, etc then those can be done fairly trivially. If you want to check the status of a proprietary Windows service that is not network-accessible, then you would need to run the script on that box itself (of course).

I would suggest browsing www.CPAN.org for modules that may help in polling Windows services
Also the following books may be helpful:
Learning Perl on Win32 Systems
Perl for System Administration

I have the latter book and it does have some useful examples of things you can do on Win32 systems using some of the Win32-specific PERL modules.

Thank you for your answer but, as you said, i have to check a proprietary windows service status.
I have already searched on CPAN but it only provides system administration scripts for "system" to "same system". My pb is to check a windows service status from a linux system.
I think i will use a link to an another apache web page based on a win32 system but if there is another way to resolve my pb without using another computer, i am really interresting.

The Win32 modules should allow you to do this. I seem to recall that you can specify remote machines as a parameter to query the services. It's been a while since I've looked at it and I'm going by memory (always a scary thing), but I'm pretty sure it works that way. I do this at work but a slightly different way. I just use "MSINFO32 \\server /r server.txt" in my script (looping thru all the servers) and check the output of the text file. This way I can verify that all the automatic services are running, keep an eye on disk space, etc.

You may be able to save yourself some work by using an established project such as nagios:
