#31 Colinux Networkconnection via Colinux.exe
Hi!
The Idea is to make outgoing Networkconnections of
Colinux via the Colinux.exe.
From the view of the user, when debian makes an apt-get
install via ftp, in windows the colinux.exe connects to
the ftp-server.
The advantage would be, that users installing Colinux
the first time, do not need to worry about the
networking stuff.
Even more such a colinux could be moved to another pc
and started there without touching the windowssystem,
i.e. without installing neither tapi nor wincap.
But the main reason is, that both networking mechanisms
lead to problems under certain conditions and even
security trouble:
a) when using "Internet Connection Sharing" for TAPI,
even some local Windows Programs use this way to
connect to internet. So if using an applicationlevel
Firewall (Tiny/KerioFW 2.0.x) it is impossible to block
these Applications without blocking colinux.
b) using WinCap doesnt work on some Networkcards
(mostly WLAN). Moreover installing WinCap is a
securityhole at its own, cause also other apps have
access to wincap.
If one needs colinux to have its own virtual
networkdevice, he can still install the Tapi-Drv.
But for connecting to the Internet, routing the traffic
directly through the colinux.exe, would be much better.
What do You think? Would that be to complicated to
implement?

If you use SLiRP as one and only network device, then can
do it all.
SLiRP is a virtual networking daemon and use current
windows outgoing networking all times. Is only little
slower as TAP or PCAP, becaus it's a windows user program
only (no device drivers). It's usable from version 0.6.3-
pre13 or newer.

I'm closing this feature request since as Henry pointed out
this is all essentially implemented with the SLiRP network
option currently available in 0.6.2, with an improved
version in 0.6.3 about to be released. SLiRP is very likely
to become the default networking option in future coLinux
(as yet to be determined or written in stone)

Hi,
I didn't manage to get SLIRP Mode work, i.e. I got no
Netwokconnection.
Which IP-Address/Mask do I need to set inside CoLinux?
Does it wrap eth0 or do I need to install & use a
SLIP-Driver on my Debian beneath CoLinux.
Well I used SLIRP under Win3.x many Years ago to get full
network-access via Terminal/Modem connection to my
University. I remember that Slirp wrapped the SLIP-Protocol
over a terminal session and that I had a 10.0.0.0 Net on my
PC mapped to the real IP of the Unix-Host on the other side
of the telefone line.
But how do I use this for Debian Linux?
Thanx in advance

Rainer,
http://wiki.colinux.org/cgi-bin/Network go to section 2.3 it
should have everything you need to know about configuring
SLiRP in any linux (debian or otherwise). The sort of it is
you use the 10.0.2.15 as the address and 255.255.255.0 as
the mask, and 10.0.2.2 as an gateway and 10.0.2.3 to use
your windows as a dns server
The configuration is eth0=slirp instead of eth0=tuntap or
the like. Unless you need to redirect ports to coLinux then
it gets more complicated.
Hope that gets you going in the right direction,
George
