LKCD Network dump over netpoll patch (2.6.0-test9)

From: Prasanna S Panchamukhi
Date: Mon Nov 10 2003 - 08:51:33 EST


Hi,

This patch includes LKCD networkdump code changes over netpoll API's for
kernel version 2.6.0-test9. Both the netconsole and network dumping can be
achieved. Procedure for netdumping is explained below:

1. Apply the netpoll-core.patch and netconsole.patch (http://www.selenic.com/netpoll/)
2. Download the LKCD code from the cvs using
cvs -d:pserver:anonymous@xxxxxxxxxxxxxxxxxxx:/cvsroot/lkcd login (presee enter key for passwd)

cvs -z3 -d:pserver:anonymous@xxxxxxxxxxxxxxxxxxx:/cvsroot/lkcd co 2.6
cvs -z3 -d:pserver:anonymous@xxxxxxxxxxxxxxxxxxx:/cvsroot/lkcd co lkcdutils

3. Copy the lkcd files to the kernel source directory.
#cp -r ../2.6/* ./linux-2.6-test9/
4. Apply the kernel-changes.patch from the 2.6/patches directory.
5. Apply the pollcontroller.patch from the 2.6/patches
directory now.
6. Apply the lkcd-netpoll.patch(below)
7. Buid the kernel with LKCD network dumping enabled ;reboot and insert the dump_netdev.o module.

8. You also need to install and setup the lkcdutils.
#./configure; make ; make install.
#cd netdump
#make; make install.
9. Configure the netdump fileds in the /etc/sysconfig/dump file.
#you need to specify the local port,remote port, local ip, target ip and device name for netdump.
eg : DUMP_ACTIVE=1
DUMPDEV=eth0
DUMPDIR=/var/log/dump
DUMP_SAVE=1
DUMP_LEVEL=2
DUMP_FLAGS=0x40000000
DUMP_COMPRESS=0
PANIC_TIMEOUT=5

TARGET_HOST=9.182.14.40 #h set this to vaild hostname/IP
TARGET_PORT=6688
SOURCE_PORT=6688
ETH_ADDRESS=00:07:95:E6:08:FB

10. Run lkcd config and now you can try test dumps..
