RE: [K12OSN] Random Program crashes



Title: Message
I was trying to finish compiling the 2.4.23 kernel for my first time (never compiled a kernel before).  I run into an error when I try to "make dep", I get "gcc:command not found".  If you can tell me what to do to get past this step I can abort the 2.4.23 install and try for the new 2.6.  I have already installed 4.0 about 10 times in the last week trying to narrow down the cause of the problem, and although my results are different on different hardware configurations, I can't help but believe it is software related (Same hardware runs 3.1.2 great, I am running multiple boot systems, boot to 4.0 problems, boot to 3.1.2 no problems).  I have 2 running 4.0 installs waiting for me to crash attempting a new kernel :-)
 
Much like you I have had trouble with internet communication, programs crashing without errors, problems with DHCP and so on.  I really want to use the latest and greatest but there is still some work left.  Luckily I am not in a production environment yet.  The purpose of all this testing is for me to create a demo lab to prove to administration of about 7 schools how stable and awesome Linux is, I don't dare bring them in right now.

Hi Jim,

Let me save you some time ....... I've tried 2.4.22, 2.4.23, 2.4.25 on three identical servers ... not one behaves the same !!! 2.4.23 seems to deal with GCompris - so far 10 hours up but Netscape &  OO still crash, on 2.4.25 users cannot login (thin clients) the workstations start & get a login screen but when a user logs in the session "disappears" and the workstation returns to the login screen ??????
Again the log files have no error messages, just the normal dhcp request from ws00x, session opened, session closed ..... is there a 2.5 ??? :-D
The strangest is that although I can ping from one server to the others & the workstations and get internet access on the workstations two of the servers cannot get access?
My setup is a modem-cable into my first server & out to the  switch (server 1 has its own subnet 192.168.0.0 & clients)
Server 2 has an "in" from switch1 & an out to another switch2 with its subnet 192.168.100.0, the gateway  is properly defined as Server 1
Server 3 has an "in" from switch1 & an out to another switch3 with its subnet 192.168.200.0, the gateway  is properly defined as Server 1

So before I dive into an abyss of unknowns ........ I wanted to see if anyone else has taken the dive :-)

Hi All,

Has anyone tried the 2.6 kernel with V4.0 ?
Since there seems to be a number of issues with the current 2.4.22;
    networking (kudzu, neat)
    applications (GCompris, OO, Netscape ) that I have tested and had "crash/close" with no information, messages.
I thought it might be an idea to explore the next major kernel  release, since I value the suggestions and comment of this group I'm throwing this out .....

(BTW Julius I've also spent the weekend through 'till today configuring 3 K12LTSP servers with their workstations, granted my experience/knowledge is limited with K12 but this new version is doing a lot of strange things. Jim - this is NOT a critique of your fine work!)

    I will finish the tests on the existing hardware and on 
the new box
just to determine if this is a hardware or a software issue.  


I tried compile my own kernel from preinstalled sources. Compilation was
OK but server crashes again after 5 hour working with normal load. Now I
stopped messing with preisntalled 2.4.22 and use my own 2.4.23 kernel.
So far so good. Uptime 6 hours. 
I found solution for wine - precompiled binaries not working with 2.4.23
kernel. I compile wine from sources. Looks solution for me. At least it
works on test server.

I however have no idea how to 
exchange kernels
but I do have a linux for dummies book (that is me) and will try the
kernel swap after that.

It very simple but need some time :)

1. download kernel sources to /usr/src (i use .tar.gz)
2. Unpack it (i use "tar zxvf linux-2.4.23.tar.gz")
3. cd to your unpacked kernel souces dir (and all commands give here).
4. make mrproper
5. copy your existing kernel conf  here and rename it .config 
(i found existing conf /boot/config-2.4.22-1.2135.nptlsmp)
6. make oldconf  (and anwer any questions with ENTER (default). Also, if
you have SMP, answer 8 to processor count)
7. edit  Makefile and remove comment "export  INSTALL_PATH=/boot". Also
edit your favourite "extraversion"
8. make dep clean bzImage (and be sure it ends without errors)
9. make modules (and be sure it ends without errors)
10. make modules_install (and be sure it ends without errors)
11. Copy /usr/src/yourkernel/arch/i386/boot/bzImage to
/boot/vmlinuz-2.4.23-1 (put your favoutite kernel name here)
12. Maybe you need "mkinitrd /boot/initrd-2.4.23-1.img 1.4.23-1" (put
your new kernel module folder name here from /lib/modules/) I don't need
initrd, because controller and ext3 drivers are compiled to kernel (not
as modules)
13. write new section to /boot/grub/grub.conf (do not chandge default
kernel)
14. Reboot and choose new kernel.

(if it works, try customize your kernel with "make menuconfig")

Thats it.
