How to build a DKMS package

AceLan — Fri, 03 Sep 2010 12:31:54 +0000

I’m trying to log how I built an rtl8190 DKMS package, the info may not correct and only works for me.

tar xf rtl8190p_linux_2.6.0011.1029.2009.tar.gz sudo mv rtl8190p_linux_2.6.0011.1029.2009 /usr/src/rtl8190p-0011.1029.2009/

Modified the Makefile and copy out the .ko file
@make -C $(KSRC) SUBDIRS=$(RTL819x_DIR)/HAL/$(HAL_SUB_DIR) modules + cp ./HAL/rtl8192/r8190_pci.ko .

Prepare files needed, “dkms.conf”, “install.sh”, “remove.sh”
% cat /usr/src/rtl8190p-0011.1029.2009/dkms.conf PACKAGE_NAME="rtl8190p" PACKAGE_VERSION="0011.1029.2009" CLEAN="make clean" BUILT_MODULE_NAME[0]="r8190" DEST_MODULE_NAME[0]="r8190" DEST_MODULE_LOCATION[0]="/updates" POST_INSTALL="install.sh $dkms_tree/$PACKAGE_NAME/$PACKAGE_VERSION" POST_REMOVE="remove.sh" AUTOINSTALL="yes"

% cat /usr/src/rtl8190p-0011.1029.2009/install.sh cp -a firmware/RTL8190P /lib/firmware/
% cat /usr/src/rtl8190p-0011.1029.2009/remove.sh rm -rf /lib/firmware/RTL8190P
And remember to give them execution permission
sudo chmod a+x /usr/src/rtl8190p-0011.1029.2009/{install,remove}.sh

Add this driver into dkms system
% sudo dkms add -m rtl8190p -v 0011.1029.2009


Creating symlink /var/lib/dkms/rtl8190p/0011.1029.2009/source ->

Try to build it
% sudo dkms build -m rtl8190p -v 0011.1029.2009

Develop Android apps by Eclipse on Ubuntu

AceLan — Thu, 07 Jan 2010 07:19:59 +0000

I’m trying to use eclipse to write a hello android program, but encountered a problem while installing ADT plugin for eclipse.

The following is the solution and from this bug report, the problem is fixed in eclipse (3.5.1+repack~3-0ubuntu1).

1. Open eclipse and Help -> Install New Software…
Add http://download.eclipse.org/releases/galileo/ to the update sites list
Using the filter to filter out WST and install it.

2. Restart eclipse, Help -> Install New Software…
and install the Android ADT as described on the android website.

3. Window -> Preference -> Android
SDK Location – given the correct location of the Android SDK.

4. File -> New -> Project
Android -> Android Project – Enjoy.

What a stupid thing I did!!

I’ve been curious who made the test_branch_1 branch on the ubuntu git tree for a long time. And today I checkout that branch and see the amazing log.

It was my second day, and I didn’t know too much about git. Of course, the branch was already been deleted, and nobody will know what I had did. :p

Add extra work for kernel package

AceLan — Wed, 28 Oct 2009 02:27:35 +0000

If you would like to do more extra work while packaging the kernel package, modify this file
debian/rules.d/2-binary-arch.mk

If you would like to do more extra work after installing the kernel package, modify this file
debian/control-scripts/postinst

My git commands backup

AceLan — Wed, 21 Oct 2009 07:26:50 +0000

On a new installed machine, you have to add your info in the ~/.gitconfig
git config --add user.name "AceLan Kao" git config --add user.email acelan.kao@ccc.ccc

Clone Jaunty kernel and add my public repository, so that I can publish my modification to public git tree.
git clone --reference linux-2.6 git://kernel.ubuntu.com/ubuntu/ubuntu-jaunty.git git remote add zinc git+ssh://zinc.ubuntu.com/srv/kernel.ubuntu.com/git/acelan/acelan-jaunty.git
NOTE. The reference git tree(ex. linux-2.6) shouldn’t be removed under any circumstances, or the reference object will disappear and the git tree will become unusable. The file .git/objects/info/alternates will record the referenced git tree, try to specify an available one, if you removed the original reference tree accidentally.

We usually cherry pick upstream kernel commit, this is the command.
git cherry-pick -s -e -x aa1812b3e

And the request letter format for cherry pick.
git request-pull \ \ git://kernel.ubuntu.com//my-jaunty.git \ > new_branch_1-request-pull.txt

Postfix on Ubuntu

AceLan — Mon, 19 Oct 2009 10:35:45 +0000

I can’t receive email after fresh installing Ubuntu on my server. I copy the old postfix config(main.cf) to the new installed server, but the new email arrived. I found there is a statement in the main.cf
smtpd_client_restrictions = check_client_access hash:/etc/postfix/access
But there is no such a file under /etc/postfix directory, so I copied access and access.db from the old server, then I received spams.

To cowork with my gmail account, I add a pop3s account on gmail, so I need some extra settings to activate the pop3s service.
Modify the setting in the /etc/dovecot/dovecot.conf
protocols = pop3s
and uncomment this two lines
ssl_cert_file = /etc/ssl/certs/ssl-cert-snakeoil.pem ssl_key_file = /etc/ssl/private/ssl-cert-snakeoil.key
Then restart dovecot, you can try telnet localhost 995 to see if the the port if opened.

For the postfix, you have to run the following commands.
openssl req -new -x509 -extensions v3_ca -keyout cakey.pem -out cacert.pem -days 3650 postconf -e 'smtpd_tls_auth_only = no' postconf -e 'smtp_use_tls = yes' postconf -e 'smtpd_use_tls = yes' postconf -e 'smtp_tls_note_starttls_offer = yes' postconf -e 'smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key' postconf -e 'smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt' postconf -e 'smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem' postconf -e 'smtpd_tls_loglevel = 1' postconf -e 'smtpd_tls_received_header = yes' postconf -e 'smtpd_tls_session_cache_timeout = 3600s' postconf -e 'tls_random_source = dev:/dev/urandom'

And add these two line in the /etc/postfix/master.cf
smtps inet n - n - - smtpd smtps inet n - n - - smtpd -v -o smtpd_tls_wrappermode=yes -o smtpd_sasl_auth_enable=yes

Done.
