My poor forgotten little blog. I will post something cool soon 🙂

After a bit of irc inspired digging, I’ve built a newer rev of LSOF and fortunately, it appears that the upcoming 4.83 release restores functionality on Solaris which has been broken for a while!

Will kick out some packages once it’s released.

(And yep, it supports ZFS)

If you juuuuuuust can’t wait, here are some simple instructions on building it:

Download and extract the 4.83K tar.bz2:

Be slightly baffled by the confgure script, but continue on as follows:

This configuration step (the Inventory script) takes inventory of
the lsof distribution. The script runs for a minute or two while
it checks that all the subdirectories, information files, scripts,
header files and source files that should be present really are.

It’s not absolutely necessary that you take inventory, but it’s a
good idea to do it right after the lsof distribution has been
unpacked. Once the inventory has been taken, this script creates
the file ./.ck00MAN as a signal that the inventory step has been
done.

You can call the Inventory script directly at any time to take
inventory. You can inhibit the inventory step permanently by
creating the file ./.neverInv, and you can tell the Configure script
to skip the inventory and customization steps with the -n option.

You may now customize the machine.h header file for this UNIX
dialect. The customizations will take effect when you compile
lsof. You may also choose to skip customization and proceed to
the compilation of lsof.

If you don’t know if you need to customize or want to know more
about what you can customize, consult the 00DCACHE, 00FAQ, 00PORTING,
and 00README files of the lsof distribution. You might also find
it helpful to examine the machine.h header file for the dialect
you’re customizing.

You don’t need to use this procedure to customize lsof; you can
edit the machine.h header file directly. If you later decide you
want to use this procedure to customize machine.h, execute the
./Customize script.

Enjoy 🙂

I finally reached melting point with the gnome which ships with Solaris 10, and so I decided to take a look at some other window managers.

A bit bored of Flux and Openbox, I finally settled on DWM.

For those of you who don’t know – DWM is an exceptionally lightweight window manager (weighing in at just over 2000 lines of C) which has no configuration outside of config.h, and should be pushed out with the next release over at blastwave (my sources tell me this will be today).

To get started:

# /opt/csw/bin/pkgutil -U
# /opt/csw/bin/pkgutil -i dwm-dtlogin

This will pull down DWM itself, the dtlogin integration files (/etc/dt/config), urxvt and the artwiz fonts. Select DWM from your sessions list in dtlogin, and press MOD4(Windows Key) + Shift + Enter to open a terminal.

I’ve added DMENU to the repo for those who want it, too.

Some obligatory screenies.

“Floating Layout”

“Tiled Layout”

The patch for the zenburn-esque colour theme is here

Have fun! 🙂

Over at blastwave, we’ve been hard at work getting a new perl package togeather, and one of the things we like to do is have 64 bit binaries in the same package as the 32 bit binaries..

We achieve this with the help of a binary called isaexec; our packages install their binaries into (e.g for perl) /opt/csw/bin/sparcv9/perl and /opt/csw/bin/sparcv8/perl, and then a hard link is created as /opt/csw/bin/perl=isaexec in our package prototype.

When /opt/csw/bin/perl (which is actually isaexec) is run, it uses getexecname() and isaexec() to run the correct binary for that host.

On solaris 8 however, we noticed a bit of a strange problem. The /opt/csw/bin/perl link was working as expected, but when we use it in a script #!, we were seeing some unusl behaviour.

To demonstrate this, we’ll set up some isaexec links for bash:

root@mimas:/opt/csw/bin > cp bash sparcv8/bash_2
root@mimas:/opt/csw/bin > cp bash sparcv9/bash_2
root@mimas:/opt/csw/bin > ln isaexec bash_2

Next, a little script which calls the isaexec’d up /opt/csw/bin/bash_2:

houston@mimas:/tmp > cat test.sh
#!/opt/csw/bin/bash_2
echo test
houston@mimas:/tmp > ./test.sh
/opt/csw/bin/bash_2: cannot find/execute “test.sh” in ISA subdirectories

To cut a very long story very short – there is no trivial way around this, the problem lies deep within exec on Solaris 8.

As a result, we’re making the sparcv8 binaries for perl (and anything else) the default for Solaris 8.

The v9 bins are still there, but if you want them you’ll need to use /opt/csw/bin/sparcv9/foo in your scripts.

Peace!

Not a very interesting update, but I felt compelled to write something:

I’ve been back in the real world for a few weeks now, and of course the first thing I needed to do was set up a workstation.

Initially, my first choice was opensolaris-dev (in this instance, build 127) which turned out to be a rather painful experience. Besides the random crashes, 10 minute boot times and broken audio drivers, the real problem for me is that opensolaris has one of the worst packaging systems ever made.

Many people with much better prose than mine can explain the problems with IPS, if they weren’t painstakingly obvious from the moment you first used it – so I’ll leave that rant for another day.

So, I went off to sun.com and downloaded the latest Solaris 10 release and stuck it on my machine, and so far everything is working great – and compared to OpenSolaris it’s rock solid stable.

To make it more usable, the first thing I had to take care of was the lack of a decent terminal program, the gnome-terminal that ships with Solaris 10 is terribly dated, and when I’m inside vim and the cursor is over a comment, it disappears!

So I logged into the blastwave farm and made a package for urxvt, which should be available in the repo soon!

Some obligatory screenshots:

Color test:

Next up was to install the latest Firefox which you can download from their website.

My next task is to get a proper window manager on there, such as awesomewm – which’ll come when I find some free time! 🙂

Gah!

That was a very long time without an update!

I shall be returning to the ‘real’ world soon; having found exactly how deep the rabbit hole goes, I’ve consumed the blue pill and am working on a return plan to the UK.

 

Bah! But, for the best 🙂

Expect some cool stuff soon, I will be returning to my old projects, finally!

-houst0n

Apologies for the lack of updates! (although, as of this moment hardly anyone is reading this, so I’m not sure exactly who I’m apologizing to!)

Things have been pretty crazy with quitting my job and getting prepared to relocate 10,081 miles from here in Scotland to Brisbane, Australia.

So, the gory details: I’m landing in Brisbane on the 13th if anyone wants to hook up for a beer, if not – I might catch you at the next QOSUG!

I’ll post some more Solaris related stuff as I get the chance.

In related news – we over at Blastwave have been rather busy, expect some cool new things (Including FreeNX!!!) soon!
