[SOLVED] Why module can't loaded?

luofeiyu · 10-31-2017, 02:42 AM

OS :centos 7

Code:

yum install -y ipset
ipset create vader hash:ip  
ipset v6.29: Kernel error received: Operation not permitted
iptables -I INPUT -m set --match-set vader src -j DROP 
iptables v1.4.21: Kernel module xt_set is not loaded in.

No module in my centos.

Code:

lsmod 
Module                  Size  Used by
cat /proc/modules
nothing as output

Module can't be installed.

Code:

modprobe  xt_set
lsmod
Module                  Size  Used by
Nothing as output

How to add module for my centos ,and how to make ipset run for me?

Have a look at the modules under /usr/src/modules or /lib/modules.

luofeiyu · 10-31-2017, 03:37 AM

ls /usr/src/modules
ls: cannot access /usr/src/modules: No such file or directory
ls /lib/modules
ls: cannot access /lib/modules: No such file or directory

Can you install the kernel sources?
And compile the kernel with the modules yourself?

luofeiyu · 10-31-2017, 04:50 AM

The centos is on my vps ,how to compile the kernel with the modules myself?

1. Install kernel sources.
2. Open a terminal
3. Login as root
4. "make menuconfig"
5. Select all nessecary options - help is availale. You can also ask here. Search in Internet for more specific howtos to configure the kernel
6. Install the kernel and the modules. "make install"

1.install kernel sources

Code:

sudo yum install rpm-build redhat-rpm-config asciidoc hmaccalc perl-ExtUtils-Embed pesign xmlto
yum install -y  gcc
yum install -y  bc 
yum install -y  python-devel
yum install -y  newt-devel
yum install -y  elfutils-devel
yum install -y  zlib-devel
yum install -y  binutils-devel
yum install -y  bison  
yum install -y  audit-libs-devel
yum install -y  numactl-devel
yum install -y  pciutils-devel
yum install -y  gettext
yum install -y  ncurses-devel
rpmbuild -bp --target=$(uname -m) kernel.spec
mkdir -p ~/rpmbuild/{BUILD,BUILDROOT,RPMS,SOURCES,SPECS,SRPMS}
echo '%_topdir %(echo $HOME)/rpmbuild' > ~/.rpmmacros
cat /etc/redhat-release
7.2.1511
wget  http://vault.centos.org/7.2.1511/updates/Source/SPackages/kernel-3.10.0-327.36.3.el7.src.rpm
rpm -i kernel-3.10.0-327.36.3.el7.src.rpm  2>&1 | grep -v exist
cd ~/rpmbuild/SPECS
rpmbuild -bp --target=$(uname -m) kernel.spec

To reboot my vps.

2. Open a terminal
3. Login as root

4. make menuconfig
make: *** No rule to make target `menuconfig'. Stop.

How to do then?

4. make menuconfig

before you can make this, you must change the directory.
cd /usr/src/linux

luofeiyu · 10-31-2017, 08:13 AM

cd /usr/src/linux
-bash: cd: /usr/src/linux: No such file or directory
ls /usr/src
debug kernels
cd /usr/src/debug
make menuconfig
make: *** No rule to make target `menuconfig'. Stop.
cd /usr/src/kernels
make menuconfig
make: *** No rule to make target `menuconfig'. Stop.

Can you post the content of the directory /usr/src ?

luofeiyu · 10-31-2017, 09:35 AM

tree /usr/src
/usr/src
├── debug
└── kernels

Keruskerfuerst · 10-31-2017, 10:07 AM

It is nessecary to install the kernel source.

Keruskerfuerst · 10-31-2017, 12:07 PM

And read some information about configuring the kernel, e.g.: http://how-to.wikia.com/wiki/How_to_...e_Linux_kernel
or use google to find some information about that.

You have to configure the kernel.
