[uml-devel] A new UML-based network platform
Hello, I have made a tool to have a network in a PC, based on UML but with only one process to manage the whole network. The virtual network is dynamic, you can connect/disconnect links between machines while it is running. The software is at http://clownix.net it is called uml_clownix_04. Uml is a great tool for multi-machine network developement! Regards - This SF.net email is sponsored by: Splunk Inc. Still grepping through log files to find problems? Stop.

[uml-devel] uml_clownix: new network utility
Hello, A complete solution, for networking with uml is now availlable at http://clownix.net it consists of a 200Mega compressed file system, the uml kernel 2.6.23.8, and a new networking layer called uml_clownix. This platforme was made to test ipv6 mobility, the links between uml machines can be broken and set back in operation. The file-system is equiped with tshark and has all the latest softwares (gcc-4.2.2, glibc-2.7 ...) Regards - This SF.net email is sponsored by: Microsoft Defy all challenges.

[uml-devel] uml and firefox
Hello, I get a strange behaviour as far as isolation is concerned between an uml machine and the host, my uml machine is isolated from any network, if firefox is already running in the host, running firefox in the uml machine creates an instance of firefox that is not isolated: the browser can browse the net. if firefox is not already running in the host, then the firefox in the uml reacts normaly, that is, it cannot get to the network. What can be the cause of this or did I dream it? Regards Vincent Perrier - This SF.net email is sponsored by: Microsoft Defy all challenges.

[uml-devel] g_timeout_add
Hello, It seems that g_timeout_add glib timeouts are not accurate when there is no gtk activity on an uml target. This may be a glib problem since I cannot check that it does not occur on my host. When gtk events occur through mouse moves, then the timeout is good (a 5 sec timeout) if no graphical activity exists, the timeout takes an average of 12 sec, even if there is console activity on the uml machine. Sorry that my host has no gtk to double-check on a physical machine. Vincent Perrier - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [uml-devel] g_timeout_add
With strace, when I do nothing on the gtk screen, we get
what is under, it seems that the poll has a 5000 milli-sec
timeout, but takes 10 sec to wake.
When I move the mouse on the gtk screen, there are too many
events on the screen to see anything but I can send it if you
need it.

Here it is:
By the way, do you use other very interresting tools such as strace?
if so could you give me names?

[uml-devel] Timeout in the select
Hello, At http://clownix.net, my new machine has the select timeout problem, if you download it, the file /usr/src/clownix_liv_feb_2008/jeff_tst.c in the virtual machine has a piece of software not behaving as it should, the 1 second timeout of the select is doubled. Could you tell me if this is specific to my machine or if others have the same problem. Regards Vincent Perrier - This SF.net email is sponsored by: Microsoft Defy all challenges.

[uml-devel] 2.6.17 host and 2.6.24.2 uml
Hello, Somebody having a mandrake distribution with a 2.6.17 host kernel says that his 2.6.24.2 uml kernel is not syncing at startup. With a 2.6.18 pclinuxos kernel, it works, is it possible that there is a problem associated to the 2.6.17 kernel or is it something else?
