Solaris 2.6 x86

Introduction

If you search eBay for "Solaris" you'll find a lot of people selling old copies of 2.6, but all of these copies are for the SPARC platform. 2.6 for Intel was alleged to exist, but after leaving a fruitless search going for months and months, I started to wonder if it was a myth.

And then, one day, out of the blue, something turned up. It was too good to be true. I didn't believe it at first. But there it was. Solaris 2.6 for Intel.

Woohoo!

When it came in the mail, I was even happier. The packaging might have been reused from something else, but boy was it cute.

solaris 2.6 - 1. packaging

Also, the shipper included a little note on cat-themed stationery thanking me for my purchase, AND refunding me my change from shipping! kri-bri - best seller ever.

I was so wrapped up admiring the packaging that I almost forgot about what was inside. But there it was, the mythical Solaris 2.6 for Intel, shiny and still shrink-wrapped.

It almost felt wrong to open it. "Fortunately" I didn't have to right away. I was really busy at the time so all I could do for a week or more was put it on the shelf and wait for a break.

VM Configuration

(Two Weeks Later)

Not terribly long ago I'd managed to get the unexpectedly less-rare Solaris 2.5.1 x86 running in VMware 8.0.6. It had required jumping through a few hoops. Even longer ago I'd installed Solaris 7 x86, and in comparison, it had required jumping through flaming hoops while riding a unicycle. I was curious where 2.6 would fall on this spectrum and a little nervous that it might require some set of new gymnastics.

Turned out there were few surprises.

Through trial and error I discovered that 2.6 only supports about a 4G disk. Or, at least that a 4G disk image works but an 8G does not. You can install to an 8G disk, but you can't boot from it after installation. Or at least I couldn't get that to work. So, 4G disk.

128mb of memory seemed to be enough. I told VMware that the guest OS was Solaris 8. I removed the sound card, and aimed the virtual floppy at the Solaris Device Configuration Manager image.

Installation

Right away I got an odd error:

    Loading driver blogic.bef
Failed to initialize host adapter

It looked like Solaris wasn't too happy with VMware's Buslogic implementation. My virtual drives were on the virtual IDE controller though, and it turned out I could just hit return to keep going.

The rest of the installation was straightforward-ish. It was a lot like other Solaris installations, with some of the same quirks. It didn't ask for DNS info or a default route. Several times it tried to get me to run kdmconfig and I had to either Bypass or Bypass and Suppress it.

The oddest thing was disk partitioning, but it was no odder than usual. In fact it was exactly the same as 2.5.1 and 7. You have to uncheck and re-check c0d0 (c-zero d-zero) or the installer will think that it has partitions defined even though it doesn't. Also, the default filesystem layout includes a small root and large /export/home and the editor for removing /export/home and resizing root isn't very intuitive.

But I was used to that, did that, and pretty soon it looked like this:

solaris 2.6 - 2. install

The main installer ran for a while, then it appeared to install some updates. I'd told it to not to auto-reboot so I'd be able to remove the floppy. When it was done it dropped me to a root prompt, I removed the floppy, halted the system and rebooted.

solaris 2.6 - 3. first boot

All right!

Post-Install Tweaks

Everything wasn't perfect yet though.

Even though I'd bypassed and suppressed configuration of the graphical environment it still tried to start anyway, so I disabled it for real.

dtconfig -d

Fortunately the emulated PCNet NIC was recognized (unlike in 2.5.1), but the installer didn't ask for a default route or DNS info so I configured that manually too.

Default route:

echo "192.168.123.254" > /etc/defaultrouter

/etc/resolv.conf

domainname firstworks.com
nameserver 192.168.123.37
search firstworks.com

/etc/nsswitch.conf

hosts: files dns

I rebooted after that step to make sure everything network-related came back up correctly on restart, and it did.

The default path didn't include some important stuff, so I updated /etc/profile

PATH=$PATH:/usr/ccs/bin:/usr/ucb:/usr/openwin/bin:/usr/openwin/demo:/usr/dt/bin
...
export LOGNAME PATH

I'd told the installer not to create a /export/home partition, but if you don't create the partition then the directory doesn't even get created. This is where home directories are created by default though, so I added it.

mkdir /export/home

I also added a user for myself.

useradd -m -d /export/home/dmuse dmuse
passwd dmuse

And I added /usr/local and /opt/sfw because I intended to install some software in those locations later.

mkdir /usr/local
chmod 777 /usr/local
mkdir /opt/sfw
chmod 777 /opt/sfw

As with Solaris 2.5.1 and 7, software was difficult to come by. There's plenty of source code out there but what was I going to compile it with?

Also as with 2.5.1 and 7, the solution was to build a compiler targeted for 2.6 on a different version of Solaris. This time I built gcc 2.95.3 on Solaris 9. I first tried building on 11 and 10 but the versions of gcc that I had installed on those systems appeared to be too new to build 2.95.3.

On Solaris 9, I ran:

./configure --prefix=/usr/local/gcc-2.95.3 --host=i386-pc-solaris2.6 --target=i386-pc-solaris2.6 --enable-shared
gmake
gmake install

Then I tarred up /usr/local/gcc-2.95.3, ftp'ed it over to the 2.6 VM, untarred it in /usr/local and added /usr/local/gcc-2.95.3/bin to my PATH.

As if by magic, I could now build software in my 2.6 VM.

Magic!

Software

Now that I had a working compiler, I rebuilt gcc natively and installed it under /opt/sfw.

CC=gcc ./configure --prefix=/opt/sfw --enable-shared
make
make install

I removed /usr/local/gcc-2.95.3, removed it from my path, added /opt/sfw/bin to my path (and /opt/sfw/lib to my LD_LIBRARY_PATH) and used the new gcc to build a bunch of other stuff: gzip-1.3.12, bash-1.14.7, sudo-1.6.9p23, perl-5.003_07, openssl-0.9.6h, zlib-1.2.8, openssh-3.1p1, GNU tar-1.13, apache-2.0.65, lynx-2.8.7, wget-1.5.3, cvs-1.11.23, GNU make-3.82, vim-7.4... Maybe some other stuff too.

I configured everything to install under /opt/sfw and just about everything compiled cleanly.

openssh required line 58 of openbsd-compat/bsd-snprintf.c to be commented out:

/*# undef HAVE_VSNPRINTF*/

I think that was all though.

Remote Access

It's fun to work on the console for a while, but it does get old. After building and installing openssh, I created an init script for it at /etc/init.d/ssh

#!/bin/sh

case "$1" in
  start)
        /opt/sfw/sbin/sshd
        ;;
  stop)
        killall sshd
        ;;
  *)
        echo $"Usage: $0 {start|stop}"
        exit 1
esac

exit 0

...and set it up to run at boot:

chmod 755 /etc/init.d/sshd
cd /etc/rc3.d
ln -s ../init.d/sshd S90sshd

I tried enabling X-Forwarding in /opt/sfw/etc/sshd_config

X11Forwarding yes

...but for whatever reason it never worked.

But, after starting ssh

/etc/init.d/sshd start

I could log in remotely.

solaris 2.6 - 4. ssh

I could also scp files back and forth.

The Web

I'd built and installed lynx and wget earlier and they both worked as expected.

Netscape 4.78 was available and worked but struggled hilariously with modern websites.

solaris 2.6 - 5. netscape

It did support PNG's though, which I didn't expect.

The hotjava web browser was also available but it struggled even more. Side note though... I think Solaris 2.6 was the first version to support java (version 1.1.3 no less), or at least to ship with support for it.

On the server side, I was able to get Apache working but I had to do the same Group trick that I did under Solaris 7. By default, Apache is configured to run as Group #-1. On most systems, group id's are 16-bit, -1 translates to 2^16-2, and the "nobody" group has that group id. Apparently, on Solaris, group id's are 32-bit, "nobody" has an id like 60001, and it couldn't make any sense of #-1. This fixed it though:

#Group #-1
Group nobody

I added an init script for it too, at /etc/init.d/httpd

#!/bin/sh

case "$1" in
  start)
        /opt/sfw/bin/apachectl start
        ;;
  stop)
        /opt/sfw/bin/apachectl stop
        ;;
  *)
        echo $"Usage: $0 {start|stop}"
        exit 1
esac

exit 0

...and configured it to run at boot.

chmod 755 /etc/init.d/httpd
cd /etc/rc3.d
ln -s ../init.d/httpd S90httpd 
X Windows

Solaris 2.6 comes with Sun's X server but it doesn't support VESA framebuffers so under VMware it's limited to 16-color VGA mode at 640x480.

But!

Binaries of XFree86 4.7.0 are available for Solaris 2.6 at http://ftp.xfree86.org/pub/XFree86/4.7.0/binaries/Solaris. And they work!

They do take a little coercion though.

To get it working, I downloaded the following files:

    Xbin.tgz
    Xdoc.tgz
    Xetc.tgz
    Xf100.tgz
    Xfcyr.tgz
    Xfenc.tgz
    Xfnts.tgz
    Xfscl.tgz
    Xfsrv.tgz
    Xhtml.tgz
    Xinstall.sh
    Xlib.tgz
    Xman.tgz
    Xmod.tgz
    Xnest.tgz
    Xpdf.tgz
    Xprog.tgz
    Xprt.tgz
    Xps.tgz
    Xrc.tgz
    Xvfb.tgz
    Xxserv.tgz
    extract 

Then I ran:

sudo sh Xinstall.sh

The prompts were intuitive and I installed all optional components but I told it not to create links for opengl or rstart.

I also added /usr/X11R6/bin ahead of other paths in the PATH variable and added /usr/X11R6/lib ahead of other paths in the LD_LIBRARY_PATH variable.

Configuring XFree86 (xf86config) took some trial-and-error but I eventually got it. The important settings are:

  • mouse protocol: 1. Auto
  • monitor: 2 31.5 - 35.1; Super VGA, 800x600 @ 56 Hz
  • vertical sync range: 4 40-150
  • yes, look at a card database
  • card: 0 * Generic VESA compatible
  • video memory: 3 1024K
  • color depth by default: 4 16 bits (65536 colors)

The color depth appears to have to be the same as the depth of the host display.

After configuration the mouse didn't work, but editing /etc/X11/XF86Config manually and commenting out the following line seemed to fix it:

    #Option "Device"      "/dev/mouse"

After all that I was able to get a simple X session running with startx.

Running openwin gave me an OPENLOOK session.

solaris 2.6 - 7. openwin

I was able to get a CDE session by creating an .xinitrc with:

/usr/dt/bin/Xsession

...and running startx.

solaris 2.6 - 8. cde

A graphical login was a little more difficult.

It turns out that the dtlogin program runs /usr/openwin/bin/Xsun directly, and passes it an option that the XFree86 server doesn't understand, so I replaced it with a script that removes the option:

#!/bin/sh

ARGS=`echo $@ | sed -e "s|-nobanner||g"`

/usr/X11R6/bin/X $ARGS

I'd had the same issue with Solaris 7 though, so the solution was familiar.

Enabling dtlogin was simple.

dtconfig -e

It didn't work perfectly though. As on Solaris 7, I could login and run a CDE session, but I had to use ctrl-backspace to exit the session and get back to the login.

Development

I had previously built and installed all the tools I usually use to build my software, so I gave it a try.

Rudiments required one modification. I'd added a hack at some point for FSU pthreads on SCO something-or-other, but then later disabled FSU pthreads support but forgot to remove the hack. The hack caused a problem on Solaris 2.6 and removing it solved it.

Everything else built cleanly and I was able to run the SQL Relay client software.

solaris 2.6 - 9. sqlrsh

I'd really like to get the SQL Relay server running on Solaris though.

I'm still looking for a version of Oracle or Sybase or DB2 or something that'll run on older Solaris x86. I remember seeing Oracle 8.0.5 on eBay once, but only once. I guess I should have jumped on it then.

I probably should try to build MySQL, PostgreSQL, Firebird and SQLite. I'm not sure how much work that would be but if I could get it going then it'd at least be something.

Eh, something to work on later.

Endearing Features

Solaris 2.6 has the standard set of Solaris quirks: you have to use delete for backspace on the console, home directories are created in /export/home, the default shell doesn't understand ~/, filesytem performance is not so good under VMware (untarring and rm -rf'ing take a while) and setting the domain in /etc/resolv.conf requires the "domainname" keyword rather than "domain".

2.6 also only supports 4g disks, which make sense, given its vintage - 1998. Unfortunately it also makes host cpu run at 100%. I can't say that was unexpected either though, as both 2.5.1 and 7 do the same.

So there you have it. Solaris 2.6 x86. About what I expected. Not too surprising. Not too disappointing.

I'll have to try to get more software running on it though - databases, maybe some old java. Yeah, that would be fun.
