Using NetBSD packages with OpenSolaris / Solaris

Currently lots of utilites from NetBSD are ported for Solaris. So I took latest packaging tools and compiled it for Solaris. Using this you can add NetBSD packages.

\*) Download the base bootstrap.tar.bz2

\*) Untar the contents
gtar xvjf bootstrap.tar.bz2 -C /
This would basically install all the required utils and packaging info.

\*) Set the PKG_PATH to appropriate site from where the NetBSD packages can be fetched.
export PKG_PATH=

\*) Set the PATH makes sure the /usr/pkg/bin & /usr/pkg/sbin are at first because NetBSD uses its own utils for fetching and installing packages.
set PATH=/usr/pkg/bin:/usr/pkg/sbin:$PATH

\*) If you are behind firewall or if you use proxy to download set the environment variables accordingly
export http_proxy=http://proxy-ip:port
export ftp_proxy=http://proxy-ip:port
eg) export http_proxy=http://webproxy:8080/

\*) Now juz try adding a package
pkg_add -v
eg) pkg_add -v wget

NetBSD packages are installed in /usr/pkg/bin or /usr/pkg/sbin directory

\*) To see list of packages which are currently ported visit

Sunday Dec 04, 2005 Report is a big developers event in India. Previously it used to be Banglinux which later renamed as Sun did a platinum sponsorship for this event.

Sumitha, Vinay and Mahesh took the responsibility of doing the ground work for this event.

We planned to showcase various technologies

\* DTrace
\* SMF/Zones
\* ZFS
\* Belenix
\* GlassFish
\* Netbeans

This was the major attraction within developers, every one were amazed with this technology people after seeing this demo have the below common question.

\* Is is part of OS or separate package ?
\* Is this technology being ported to Linux or any other Unix flavors ?

We started distributing Belenix live-CD. There were some common queries among developers

\* Does Belenix run on x86 pc ?
\* What advantages does Solaris have than linux ?
\* What are the features available one Solaris ?
\* What architectures does Solaris support ?

For people who were really interested we distributed Solaris 10 DVD's.

Some common queries about opensolaris :-
\* What licensing does this follows ?
\* Can I start modifying it ?
\* Can I strip down the kernel/utils and customize it ?
\* What's the Sun's strategy behind Opensolaris ?

People who handled various demos :-
Belenix - Myself, Moinak, Popuri, Ram and Anandth
DTrace - Pramod, Jalan, Ramesh, Kini, Sanjeev, Syed and Pavan
SMF/Zone - Vineeth, Shivani, Madhu, Ganga, Ganesh, Saif and Vivek
ZFS - Mahesh, Vidya, Kishore and Venku

Sorry if I had missed out some names... Each of our volunteers were so enthusiastic about this they worked hard to make it a grand success.

When compared to other stalls (google,hp,yahoo....) Sun stall was much crowded.

One of the stall GCI solutions were running a competition on Redhat linux. So I juz gave it a try and won the competition. Next day Alan Cox distributed prizes for winners. I got "The Mythical Man-Month" book as a prize autographed by him.

Some wins about
\* Solaris/OpenSolaris awareness among developers.
\* Sun stall attracted a large visitors.
\* More number of developers showed interest in Opensolaris and have signed up with BOSUG usergroup.
\* Distributed more than 1000 Belenix Cd's and arround 400 Solaris 10 DVD's.
\* India's leading newspaper The Hindu carried article about Opensolaris and Belenix.

Dtlogin add Window manager

To add other Window managers like (wmaker ,KDE, sawfish ... etc) to dtlogin can be done by creating following three files

1) /usr/dt/config/C/Xresources.d/Xresources.< window_manager >
2) /usr/dt/config/Xsession.< window_manager >
3) /usr/dt/config/Xinitrc.< window_manager >

Before creating files please note that you need to preserve permission while copying file.
(eg: cp -Ppr /usr/dt/config/C/Xresources.d/Xresources.jds /usr/dt/config/C/Xresources.d/Xresources.wmaker)

In above files replace < window_manager > with your custom name eg ( /usr/dt/config/C/Xresources.d/Xresources.wmaker )

Now lets look at files.
In Xresources.wmaker replace altDtName, altDtKey and altDtStart with appropriate file name
#cat /usr/dt/config/C/Xresources.d/Xresources.wmaker
Dtlogin\*altDtsIncrement:        True

Dtlogin\*altDtName:      Window Maker
Dtlogin\*altDtKey:       /usr/local/bin/wmaker
Dtlogin\*altDtStart:     /usr/dt/config/Xsession.wmaker
Dtlogin\*altDtLogo:      JDS_s10

After completing changes create Xsession.wmaker by copying ( cp -rPp /usr/dt/config/Xsession2.jds /usr/dt/config/Xsession.wmaker ). In Xsession.wmaker all you need to do is change the location of Xinitrc.wmaker.

And finally copy ( cp -rPp /usr/dt/config/Xinitrc.jds /usr/dt/config/Xinitrc.wmaker ). In Xinitrc.wmaker Make sure that you update the LD_LIBRARY_PATH,PATH and exec < binary_location > , if your window manager libraries and binaries are in nonstandard path.

Now logout you current session and try loggin in. If any error try logging in fail safe mode and start your custom window manager which could help you in debugging the startup issues.

I have attached all the 3 files for reference.

1) Xresources.wmaker
2) Xsession.wmaker
3) Xinitrc.wmaker

Creating Solaris Packages made easy

I allways wanted to port GNU stuffs other than (blastwave/sunfreeware) to Solaris but packaging it was bit tough. Recently came across this checkinstall utility which work for most of the Linux Distro's. It basically keeps track of all the files being installed on the system and creates package out of it. I did a quick hack ;) to work on Solaris ...right now its not fully stablized but works !!!

After installation make sure that you edit the checkinstall & installwatch scripts coz it depends on GNU textutils packages. Make sure you set appropriate environment variables in script.

You can download checkinstall from checkinstall-1.6.0beta4.tgz

Here is the demo how it works.
