hi
I am not being able to save configuration on tiny core, i have done the following

/opt/bootlocal.sh
hostname PC1
ifconfig eth0 172.16.5.2/24
route add default gw 172.16.5.254

/usr/bin/filetool.sh backup
after that it shows that i has taken all the backup but when i restart the virtual host all settings vanished.

could someone plz help me out as i m stuck on this and also how to run multiple host.

thanks

Hi, you did everything OK except one important thing ;-)

You must edit /opt/bootlocal.sh and type eth0 parameters in to this file.

1. So start vim editor:
vi /opt/bootlocal.sh

2. Now you can add eth0 parameters (IP address, mask etc.):
type letter i - this command switch vi editor into Insert mode

3. After you adding your lines you can save changes:
Press button Esc
Write :wq
Press Enter

4. Now it is file bootlocal.sh modified and you can call:
/usr/bin/filetool.sh backup



Cheers

wow it works now, thanks for your help, this virtual machine is amazing it works really fast.
is there any chance that i can run multiple host in one topology??? i have tried it but each time it gives error sometime it says '' a disk read error ctrl+alt+del to restart'' and some time that boot screen just doesnt come up.... which is very sad coz i m desperate to run multiple hosts....
and one more thing is there any chance to run winxp host as a virtual qemu host?? i have tried it but it doesnt boot up disk error comes up

thanks again for ur kind help
appreciated

Here are my findings:
>> With windows, e1000 didn't worked for me, pcnet instead works.
>> Multiple qemu host management have some issue.(Multiple host connect failed/lost; to me it seems a bug in qemu_manager)
>> If you are putting tcl, with 6-10 MB highly optimized and cusomized for your need, why not to provide an option to disable the graphics.
heres how: Manipulate tcl initrd's /etc/inittab and there you change the autologin through serial.(look at tcl homepage on how to put your own customization
without compiling the kernel. http://wiki.tinycorelinux.com/tiki-index.php?page=Remastering )
ttyS0::respawn:/sbin/rungetty ttyS0 --autologin root
Next change is to grub menu.lst file boot option (there are tons of howto on login/debugging through serial port.):
kernel /boot/bzImage quiet console=tty0 console=ttyS0,115200n8

With that when you supply -no-graphic option to qemu host, qemu won't
present the graphical window. When you try to get console from the gns3 workspace you will get a kind of telnet session similar to the one given by router, just like
any other linux prompt. If you don't specify -no-graphic option in qemu, even though in that case, you will get the qemu-emulated monitor(graphical window) along
with login-prompt on serial-port.(telnet localhost port). I used the image which is uploaded on source-forge and did all of this manipulation. Please let me know if you
want me to upload it there. Please note login user is tc on serial console without any password.(type tc and hit enter on login prompt)
For now with this customization linux.img is available at http://theanand.info

Please see the attached .png image

Hello,


Following the short tutorial:



my devices start, I can configure an ethernet interface on the router, but there is no console for the Qmeu host; I can click on console (short screen appears, but disappears very quickly [unable to view contents]), but no console.
I can stop the devices, remove the link, start the Qemu host and console session automatically appears.

Output from qemuwrapper:

qemu: Unknown network device: udp
pid: 5074
Renicing to 19
5074: old priority 0, new priority 19


I did patch qemu, or at least I thought I did. I will go back to ensure that it is patched.


Anyone have any ideas

Thanks
Billy

I downloaded qemu 0.12 source (Apparently, it does not need to be patched).

compiled and running out of /usr/local/bin

evilbit@evilbit01 ~/programs/GNS3-0.7-src $ /usr/local/bin/qemu -version
QEMU emulator version 0.12.50, Copyright (c) 2003-2008 Fabrice Bellard

same thing, no console access for the host:

I believe it is crashing on this: qemu: -net udp,vlan=0,sport=20000,dport=10000,daddr=127.0.0.1: Parameter 'type' expects a network client type
but have no idea the "type it is referring to.

I am running Linux:
evilbit@evilbit01 ~ $ uname -a
Linux evilbit01 2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:05:01 UTC 2009 x86_64 GNU/Linux

GNS Version 0.7.1
UPDATE: reverted to 11.0, patched and have it working now. Appears that qemu 0.12.5 via git does not work tho is natively patched for UDP.

Thanks
Billy

Hi,

I made small tutorial about all this stuff.

iperf a commonly used network testing tool that can create TCP and UDP data streams and measure the throughput of a network that is carrying them would help in testing QoS configurations

Hi,

Hello,

I uploaded 2 new Qemu images:

- 1 image based on microcore Linux 2.11.5 which is about the same as microcore Linux 2.10. You can download it here
- 1 image based on tinycore Linux 2.11.5, this one has a small graphical desktop, therefore you can start multiple terminals, add new applications (if connected to Internet) etc. You can download it here. This requires more RAM to work properly.

You can test these images, if everything is ok I'll post the links in the download section of gns3.net

I also uploaded the updated microcore Linux 2.10 with iperf, thanks Kaage :)

Thanks!
