colinux-devel

[coLinux-devel] Wishlist

[JOSE M. M. <tx...@cl...>]

First of all, congratulations and thanks for this great software.
Now I can get rid of vmware and cygwin and use something more useful and
open ;-)

I wanted to add something to the whislist, it is something I would find
really useful. I use colinux for getting a handy debian system when I
have to work in Windows. But I would like to get rid of the two windows
opened when colinux starts. I do not need them as I connect to colinux
through ssh, and I would thank put them in a small icon in the task bar.
(as messenger and getright do).

Another thing I would like is having a colinux machine running as a
service, not needing to log in a Windows session to have it runnning and
being started when windows starts. Later I could log in via ssh and this
way I could do a lot of things I like to do on Unix machines (tunnels,
cron jobs...) in Windows machines I cannot migrate.

Thanks for all and congratulations again for this great piece of software,
txemi.

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

[Jaroslaw K. <ja...@zd...>]

Here's my quick and dirty way to run coLinux as a service in a reliable
manner.

I have written a small service process, called CoLinuxService. When started
it spawns a new instance of "colinux-daemon.exe". The service terminates
whenever the colinux-daemon.exe dies (something difficult to achieve with
srvany.exe).

I needed a way to reliably shutdown the coLinux instance, so I developed a
quick hack. The linux machine has a special "xinetd" listener that listens
on port 15555 does nothing but shutting down the machine.

With this mechanism in place, whenever CoLinuxService receives "Stop"
command it just connects to the specified port and this initiates the safe
shutdown sequence. If "connect()" call fails the colinux-daemon.exe is
terminated.

The mechanism somewhat proved to reliable and I had no problems with it for
4, and that's why I decided to publish it.

Binary of CoLinuxService.exe is available at
http://jaak.sav.net/colinux/CoLinuxService.zip
Setup instructions inside.

Contact me if you want to get access to the source code.

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.

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

[Jaroslaw K. <ja...@zd...>]

Thanks for your comments, Chris.

Regarding the security issue for Stop - I know it's not secure at all. The
worst thing is that any network port scanner can shutdown your machine
without your

"only_from" comment is something that I've just updated in the zip file.

As for using ssh to shutdown the machine - I'm not sure if we can guarantee
that "ssh" can be safely called because windows may be in the process of
shutting down. AFAIR spawning new processes isn't guaranteed to succeed at
this moment. I may be wrong though.

BTW. The "ssh" would be run in a LocalSystem context - that means: no
profile, no HKEY_CURRENT_USER, and so on. Have you ever used ssh.exe in this
environment? How would it handle "known_hosts"?

I'm not sure I can release my source code to the public because it uses
portions of microsoft's sample code "service.c". As soon as I get rid of
this, I'll publish the sources so that everyone can play with them.

I have little understanding of this kind of windows stuff when I give this
a try today that will be my first time messing with services in windows
for real. For some reason my ideas don't always work out as often in
window as they do in Linux.

I have not messed with any of the power managemet stuff in linux but what
about the powerfail stuff in init? Could coLinux-daemon.exe somehow pass
that when told to shutdown. I'm not a programer (yet) so I'm not shure how
this would be done.

start colinux with the -d argument. The daemon window will open 
minimized, and the terminal won't open at all.

a user easy workaround is to rename colinux-console-nt.exe to 
colinux-console-fltk.  dbl click on colinux-daemon will open only 1 
window, a NT console that you can force FULLSCREEN with the usual 
alt-enter hotkeys

Suerte con eso, Jose.

note:

I feel very very bad posting this here. I know exist some feedback, 
wishlish, whatever and forums at sourceforge, I dont want to clutter 
this mail list with users mails bouncing here and there, so... maybe its 
need another mail list, a colinux-users@     EXCEPT - IF - developpers 
are not annoyed by this noise.
