Simulate network failure

Hi,

I've written small client/server program and would like to test how it
deals with the network going down, I don't have physical access to my
server, so I can't just pull the cable. I was thinking ipconfig
/release would do the job, but that dosn't appear to be installed, nor
is dhcpcd, which it apparently relies on. Or at least, I can't find
them.

Is there a way to do what I want with out installing these utilities?
Otherwise, how does one go about installing them?

ipconfig is spelled ifconfig. Try the command
man ifconfig

Please read http://www.catb.org/~esr/faqs/smart-questions.html
Always provide distribution, release when posting questions.
It could help you get better answers.

You might find ifconfig works better.

It wouldn't be too bright to try that remotely. It will only end with
you taking your server offline and having to get off your arse, crawl
over the the keyboard, and bring it back online...

What _type_ of network outage are you speaking of? no DNS, no IP addy,
no connectivity?

'ipconfig /release' is a Windows command.

You should use the 'ifconfig eth0 down' command, but then you will no more
have remotely access to your server.

So it's safer you move physicaly to the server.
