opensolaris - crle fix/restore default search path

Ok. so nobody warned you the default behavior for crle is stupid.. In OSUNIX this will be one of the first RFE that we do, but for now if you're on Solaris/OpenSolaris and need to fix your crle

-------------
crle -u -l /lib:/usr/lib
crle -64 -u -l /lib/64:/usr/lib/64
-------------

If you've shutdown or restarted you may also have to use my OpenSolaris Rescue guide

For future reference:
You should *not* use crle.. The cases where you need to use it are so limited that it shouldn't even really factor into your daily developer habits.

1) elfedit has examples of how to change the search path for a binary when you don't have the source

(This assumes you're using Sun cc.. you are using Sun cc right?)
2) If you have the source and or are building something yourself..  -L / -R is your best friend..
    -L == link path..
    -R == runtime path..

Add these to your LDFLAGS when building anything from /opt or $HOME or wherever..

Another good habit is to always include -i in your CFLAGS since it causes LD_OMGISHOULDNTUSE_THIS to be ignored.

Final draft for Ku-rei

I should have left the white background, but that can be changed..

and in black/white

Ok. so what's the name mean..

Regarding the naming,
I think 'Ku-rei' will good with her.
I'm not sure you can see the japanese font,
This may show 'Ku-rei' in Kanji font.
http://www.google.com/search?q=%8Bv%97%E9
simple leftside, and complex rightside.

Ku means long or eternity
rei means a bell. small bell. Such as,
http://store.shopping.yahoo.co.jp/roco/maturi-suzu-2.html
They are used , in Shinto celebration, as accesories, with cat collars.

Ku-rei is quite rare name as a modern japanese girl, but she's quite old and in her time it was more popular :)

You know you've gone too far when...

This little error appears a bit hard to get..  I've been working on getting the networking up on the first hw OSUNIX install.. and after updating some binaries to 64bit. (list below) I get this shiny little error..  (I'm wondering how on earth I'll fix this..)

Meaningless data...

This blog doesn't get much traffic so take the data below with a grain of salt, but I wonder what the breakdown for the Sun blogs and other Solaris related sites are?  Anyone want to share the logs/data?

How the world would be different if this were globally true....

BYOC: Bring your own compiler

After some recent questioning about the licensing differences between Sun Studio Express available for download from the sun site and that bundled with OpenSolaris I realized that the small distributions and developers would have a hard time getting the redistributable version if they didn't use IPS/pkg5.  So I started poking around pkg.opensolaris.org to see how I could download it directly.

So if you're in need of a compiler for Milax, OSUNIX, Belenix or any Solaris variant please feel free to use the below script and manifest.

Download Get-ssx

Download Manifest

Some things to consider...

    1) This should play nice with ksh93 or bash
    2) You'll need a non-ancient posix compliant awk
    3) The manifest from above is smaller, but can still be trimmed a lot
    4) A way to get multiple files from pkg.os.o needs to be added to make the whole thing faster
    5) It's unofficial and will probably break your system.. so use carefully

Edit as needed to adjust your root variable and feel free to use any manifest file since they should all be relatively just as ugly.

Nice fonts?

I need some recommendations on good fonts... suggestions?

New mascot

So refeia ended up doing a quick sketch for our new mascot.. and hoping to get some feedback..

Questions..

1. What do you think from the first sketch?
2. Is a girl mascot ok?
   
3. What's a good font that has a slightly asian feel to it and would render OSUNIX cleanly?

opensolaris nsswitch.conf

If your dns isn't working and you're resolv.conf has the correct nameservers it's most likely a problem that you're missing nsswitch.conf.  nsswitch.dns is just an example, but they aren't nice enough to explain this.

cp /etc/nsswitch.dns /etc/nsswitch.conf
svcadm restart name-service-cache

ospkg brand zone for the brave

Here's a quick howto test ospkg in a ospkg branded zone.. This will change in the future and it's super buggy (check /root/ for notes) , missing critical parts parts of the OS and the packaging hasn't been migrated away from the poc work.  With that disclaimer out of the way..
---
OSPKG brand
    # cd /usr/lib/brand/
    # gtar xvfj ospkg-brand.tar.bz

    #  zonecfg -z ospkg
        create -b
        set brand=ospkg
        set autoboot=false

        set zonepath=/export/ospkg
        verify
        commit
        ^d

    # chmod 0700 /export/ospkg/
    # zoneadm -z ospkg install
    # cd /export/ospkg

Latest OSUNIX release

    # mkdir root ; cd root

    #  bzcat OSUNIX-0.4.cpio.bz2 | cpio -idm -H USTAR

    #  zonecfg -z ospkg boot

    #  zlogin -C ospkg

password is crash

hdparm on opensolaris

You're probably looking for a more shiny way to get raw disk throughput if you're testing with hdparm, but the most comparable thing I've come across is to use the gnu dd

# (In case it's no obvious.. this will write a ~100MB file called foo)
# dd if=/dev/zero of=foo bs=1024k count=100 conv=fsync

which will give you some idea about actual write speed..

However, make sure you have compression off otherwise it'll optimize for this.. You can check with

# zfs get compression

You may also find this useful

# zpool iostat 5

Anyone still need hdparm ported over to OpenSolaris?
