Mistery resolved. making linux behave as multitask, multiusermachine.
short answer: overheat explanation: the computer would work very stable for days, without any problem. but would locked if i try to rip a dvd. Reason: transcode use almost 100% cpu. using 100% of CPU in a so demanding task would make the cpu temperature to raise. Solution: I opened the machine, put a big domestic fun in front of the board. and started the rip. Today morning the job was done and the system working.

MDK 9.1 and VIA Chipset Blues
Hello fellow Penguins, I thought it would be idea to switch to MDK 9.1, after using the 8.2 version since it came out... I tried installing. It was absolute hell ! After installing, the computer ran fast and a lot better than ever before (hardware specifics follow) but after 15-30 minutes or so (random) the comp froze completely and after reseting the machine with the dreaded reset button, half my / FS had been wiped out, due to repair errors. I had to redo the entire system *8 (!!!)* times. Two of them with full re-partitioning of the entire HD (due to the Ext3 errors). Frustration was unbelievably familiar... I decided to move back to MDK 8.2. Now my comp works perfectly for the last two weeks. Here comes the sequence of events, so maybe you guys and gals can make any sense of it and help me move to MDK 9.1: First, the hardware (source: HardDrake 0.9.3) Motherboard: MSI 6309MS with VIA chipsets: VT82C686 (ACPI) VT82C586 (IDE) VT82C586B (USB) Bridges: VT82C691 (Apollo PRO) VT82C598 (Apollo MVP3 AGP) VT82C686 (Apollo Super) Intel Celleron 850 MHz CPU 256 MB RAM nVidia Ultra TNT2 M64 Video Card 1 Quantum Fireball LP LM15 (15 Gb) HDD 1 Quantum Fireball LP AS20.5 (20Gb) HDD 1 Seagate ST310220A (10Gb) HDD 1 LG DVD-ROM DRD-81610B 1 3Com 3c590 10BaseT Vortex Ethernet Card 1 Brooktree BT878 TV Capture Card (AverMedia TV Capture98 w/ VCR) 1 Ensoniq 5880 PCI Sound Chip (OnBoard, AC97 compat.) The software: What I had is irrelevant because I wiped the HD completely. I was trying to Install MDK 9.1 with Kernel 2.4-21. I don't have the versions of all software components. My comp wouldn't stay up long enough to research it, but it can be plucked from the net. I am running Kernel 2.4.19-33mdk now, with GCC 2.96-0.76.

Hi,
I have a problem executing a fork() and exec() from a threaded
application. I'm including a minimal test case below that demonstrates
the problem. I must be missing something. If I don't create the thread
before forking, the exec works fine. IfI do create the thread, the exec
doesn't exec, and it doesn't return with an error either -- simply
nothing happens. Trying to debug this with gdb by attaching to the child
process before the exec (I put a while loop there so that I can catch
it) doesn't work -- GDB gives internal errors.
Also, an interesting thing is that if I do the exec from the father
process instead of the child, it does work. But then of course I lose
the thread that I started.
Any idea whatsoever? Thanks in advance.
Here's the output from the program on my machine:
Father

You ping a host, your machine doesn't know the MAC address(unless it's in cache). Your machine sends a packet to the destination IP, with a MAC address destination of 0x. All machines process this at the data-link layer, but only the machine with the pertinent destination IP replys, with it's MAC address. Then, proper TCP handshaking or whatever can occur. This is of course an example when the destination machine is on the LAN. This information is available on the web. Please be so kind as to read it. It's extremely basic networking information.

I still don't get something. Quoting section 7 of the IP Sub-Networking
Mini-Howto:
For the sake of this example, let us assume that you have decided to
subnetwork you C class IP network number 192.168.1.0 into 4 subnets
(each of 62 usable interface/host IP numbers). However, two of these
subnets are being combined into a larger single network, giving three
physical networks.
These are :-
__
Network Broadcast Netmask Hosts
192.168.1.0 192.168.1.63255.255.255.192 62
192.168.1.64192.168.1.127 255.255.255.192 62
192.168.1.128 192.168.1.255 255.255.255.128 124 (see note)
__
Note: the reason the last network has only 124 usable network
addresses (not 126 as would be expected from the network mask) is that
it is really a 'super net' of two subnetworks. Hosts on the other two
networks will interpret 192.168.1.192 as the network address of the
'non-existent' subnetwork. Similarly, they will interpret
192.168.1.191 as the broadcast address of the 'non-existent'
subnetwork.
So, if you use 192.168.1.191 or 192 as host addresses on the third
network, then machines on the two smaller networks will not be able to
communicate with them.
\begin{interruptRequest}
How does the 2 smaller networks know that 192.168.1.191 and 192 were
initially a broadcast and network addresses? Would they treat any one of
192.168.*.19[12] in the same way?
\end{interruptRequest}
As far as I understand, they assume that sub-networking is uniform:
they know the full network mask and know it is subnetted with a given
subnet mask. They assume it doesn't only apply to their own subnet
but to each subnet of the network. No, they wouldn't treat
192.168.*.* in this way, the full network mask seems to be
255.255.255.0 so they only assume things about sibling subnets i.e.
192.168.1.*.
--
Actually, I am not quite sure this is correct. The smaller networks do not do any
assumptions regarding other networks.
The routing decision is done at the router, while the transmitting node is totally
unaware of the subnet mask implemented at the destination network.
If you really want the guts, it depends on the routing protocol implemented on the
router and whether it supports propagating VLSM masks and whether classless routing is
implemented.
As long as routing is done by classless routing protocol, all-zeros and all-ones
subnets become available for use.
As the abbriviation of VLSM applies (Variable Length Subnet Mask), in this case you
have the benefit of not loosing bits for what would look like a broadcast or network
address,
which does not really exists.
In the above axample, with VLSM implemented, the node does the following:
1) The destination address is not in node's network, so it will be transmitted to
default gateway.
2) ARP broadcast to get the MAC address of the default gateway.
3) The node sends the packet to DG
4) DG (the router) performs a lookup in it's routing table and notices that
192.168.1.191 is in 192.168.1.128/25 network which is directly attached to the router.
5) The router queries for the subnet mask associated with the interface and sees
255.255.255.128
5) The packet will be sent through the interface attached to 192.168.1.128/25 (this is
not a broadcast !!!)
6) ARP broadcast to get the destination MAC
7) Packet gets to it's destination.
As you can see, this is a normal unicast address when using VLSM.
