[Qemu-devel] Has anyone got tun/tap network running on WinXp host / Linux guest ?

[Qemu-devel] Has anyone got tun/tap network running on WinXp host / Linux guest ?

[M. Khalid Khan]

I must confess my ignorance but I'm having no luck in setting up a tun/tap 
network between WinXP host and Suse Linux guest. BTW user-net is working 
great but I need the emulated system to be a full fledged server. From what 
I can gather by reading the docs and messages, QEMU needs a script to setup 
tun/tap network ( by default /etc/qemu-ifup ). Unless I totally missed it, 
this script must be on the host OS. Now my host OS being WinXP, I don't have 
any "/etc" or any linux like scripts. Is there an alternate script/batch 
file for Windows? If not, what is the alternative?
Care to help.
Khalid

PS: I really appreciate what is being done, keep up the good work.

You mean Linux guest and WinXP host I assume? As there is no support for tuntap
in a Windows host, and never will. (Windows doesn't directly provide the mechisms
need to do this. I am aware of two alternatives: the easy way is to set up VPN
through user-net, the hard way is to patch qemu to use winpcap.)

Look up the -redir option.

Doesn't OpenVPN use a port of tun/tap?

Yes, called TAP-Win32. I suppose you could patch qemu to use this directly, but
afaik qemu currently has no support for this mode.

Thank you so much Jim, can you give me some pointers on how to setup vpn 
through user-net in this situation. I looked at -redir option but it looks 
too tedious to set each and every port needed. If only there could be block 
redir option i.e. all ports from N to N+M on host be redirected to guest 
ports 0 to M.
Thanks again for your help
Khalid
