Re: Running CoLinux as a service (WAS Re: [coLinux-devel] Wishlist)

[<ch...@to...>]

I just downloaded http://jaak.sav.net/colinux/CoLinuxService.zip but don't
have time to try it today. Looks like a really cool idea. One thing that
you might want to add to the readme is that if the machine is setup for
bridged networking then It would be a good idea to add

only_from = windowsIPaddress

to the /etc/xinetd.d/shutdown file to add at least a moderate amount of
security. For the truely paranoid it may be a good idea to add the ability
to do something like

[stop]
cmd ssh -i c:\Coshutdownid 192.168.0.40 shutdown -h now

of course an unencrypted key pair would need to be generated for this so
it probably would not be much more secure than the current method with the
only_from added unless the id  was readable only by the administrator
group.
