Re: [Nbd] nbd-client: timeout option not working

[Valerio Pachera <sirio81@...17...>]

Yesterday I've been trying to build the module that way:

aptitude install linux-source-2.6.32
cd /usr/src; tar -xjf linux-source-2.6.32.tar.bz2
cd /lib/modules/2.6.32-5-amd64/
ln -s /usr/src/linux-source-2.6.32 build
cd /usr/src/linux-source-2.6.32
make mrproper
cp /boot/config-2.6.32-5-amd64 .config
make oldconfig && make prepare && make scripts
make CONFIG_BLK_DEV_NBD=m M=drivers/block

  WARNING: Symbol version dump /usr/src/linux-source-2.6.32/Module.symvers
           is missing; modules will have no dependencies and modversions.

modprobe -r nbd
mv /lib/modules/2.6.32-5-amd64/kernel/drivers/block/nbd.ko /root/nbd.ko.bkp
cp /usr/src/linux-source-2.6.32/drivers/block/nbd.o
/lib/modules/2.6.32-5-amd64/kernel/drivers/block/nbd.ko

# modprobe nbd
