initial netinstall of SXCE from ubuntu (no replies)

bradbobak — Wed, 04 Feb 2009 00:31:47 -0500

Well, I had to do this again, so here it is.

I was getting tired of wadling through many documentations so I have compiled this which outlines what I did to net install SXCE build 106 from an ubuntu 8.04 x86_64 machine to a sunblade 1000.

# get the .iso of the sparc image of SXCE. You can find this somewhere on www.opensolaris.org. Be sure to get the full dvd image.
# I have downloaded sol-nv-b106-sparc-dvd.iso to my home dir.
$ mkdir /mnt/sol
$ mount -o loop sol-nv-b106-sparc-dvd.iso /mnt/sol
# /mnt/sol contains the dvd's contents now

$ apt-get install rarpd tftpd-hpa bootparamd nfs-kernel-server

my ubuntu box is 10.0.0.52 on my LAN, and the sparc box will be 10.0.0.7

sparc box needs proper subnet masks. since my 10.0.0.x is subnetted as 255.255.255.0, I have to change it for the duration of the install.

NOTE : this may take down networking for your ubuntu system if it is connected to anything else.

$ ifconfig eth0 up 10.0.0.52 netmask 255.0.0.0

Booting into openfirmware (usually stop-A on the sun keyboard) you can find the MAC address of the sparc box.

# rarpd needs this info to give the sparc box an ip-address during the install.
$ echo "00:11:22:33:44:55 10.0.0.7" >> /etc/ethers
$ /etc/init.d/rarpd restart

# tftp allows trivial file transfers. The sun box needs this setup to load the initial bootstrap
# the hex number you see is simply the hex represention of the sun's ip (10.0.0.7).

EDIT : looks like newer versions of ubuntu use /var/lib/tftpboot instead of /tftpboot
EDIT : you may need to make this directory

$ cd /tftpboot
$ ln -sf inetboot 0A000007.SUNW
$ ln -sf inetboot 0A000007
# (I make both links since i'm not sure which is required, so just to be sure..)
$ cp /mnt/sol/Solaris_11/Tools/Boot/platform/sun4u/inetboot .
# my sunblade1000 requires the sun4u stuff. There is also a sun4v directory which holds an inetboot you may need to use if you don't have a sunblade.

# I haven't researched it much, but I'm guessing bootparamd provides the location of the NFS mounts of the install media.
# sparc is the hostname the sun box will use
$ echo "sparc root=10.0.0.52:/mnt/sol/Solaris_11/Tools/Boot install=10.0.0.52:/mnt/sol boottype=:in rootopts=:rsize:32768" >> /etc/bootparams
$ /etc/init.d/bootparamd restart

EDIT: forgot /etc/hosts :)

# sparc needs to be mapped in /etc/hosts
$ cat "sparc 10.0.0.7" >> /etc/hosts

# nfs needs to know we're exporting the mounted media
$ echo "/mnt/sol 10.0.0.0/24(ro,no_root_squash)" >> /etc/exports

# this part is a little tricky.. Its the only way I know of to tell NFS in ubuntu not to use nfsv4, since our sun box doesn't like this.
# you need to edit "/etc/default/nfs-kernel-server" and change the line that reads
Code:

RPCNFSDCOUNT=8

to
Code:

RPCNFSDCOUNT='8 --no-nfs-version 4'

# You do need the ''s
# ( you may wish to change this back after the install)

# restart nfsd
$ /etc/init.d/nfs-kernel-server restart

That should do it. Get into openfirmware and do a 'boot net'

Eventually you should get into the solaris installer.

You may want to remove tftpd, bootparamd, rarpd, and nfs-kernel-server when you are finished.
Don't remove them if they were in use (apt-get install did not install them).

Don't forget to change your netmask back (if you changed it above).

Happy solarising!

ssh into nokia from a wlan (no replies)

bradbobak — Wed, 12 Nov 2008 03:08:33 -0500

I spent hours trying to figure out why my wireless access point would not allow a ssh connection to my nokia.

There is a bug (power saving feature) in the nokia OS2008 (maybe others) that may cause ssh (and other) connections from your wlan to the nokia to not work correctly.

This can be fixed by running in the xterm on the nokia (you don't need to be root)
gconftool-2 --set --type int '/system/osso/connectivity/IAP/wlan_sleep_timeout' '1000'

solaris SXCE net install from linux box. (no replies)

bradbobak — Fri, 24 Oct 2008 21:35:32 -0400

[www.wuug.org]

This is outdated. Please see the above url.

I have added an entry to my blog containing tips for installing solaris for sparc (SXCE build 99 in my case) over the network from a linux box (I used ubuntu). It references another link, which is the main install guide I have used. I have just commented things I had to do differently.

www.sandmines.org is the url.

Edit: That uel no longer contains the info, as my server data has been lost.

Here is what I could remember:

Just a few things I jotted down from my experience of installing SXCE onto a sunblade 1000 doing a network install.

[znark.com] is a very good guide. Even though it is written for solaris 8, it basically works with SXCE.

nfsv4 must be disabled on the server box.

server-side common lan netmasks must be 'defaults'. (10.x.x.x requires a netmask of 255.0.0.0).

creator3d card requires SUNWffb* packages.

running a SUNPCi-2 card requires package SUNWspci2 then symlinks in /opt/SUNWspci2/drivers/solaris for sunpcidrv.2110 -> sunpcidrv.290 and sunpcidrv.2110.64 -> sunpcidrv.290.64

No-Shell Users, SSH, and Subversion (no replies)

ezod — Thu, 02 Oct 2008 12:10:09 -0400

From a discussion at the October 2008 meeting...

You can create users in UNIX without shell access still able to use the account for SSH authentication, "run-as" processes, and other things.

No Shell For You

Set their shell to /sbin/nologin (or any binary that exits with a nonzero status when run with no arguments).

If the user doesn't need a home directory, you can set that field to /dev/null.

What's the Magic Word?

Let's assume we're talking about a human user created for use with some protocol that requires authentication. Obviously, not having a shell makes it difficult for that user to set and maintain a password as usual.

For SSH-based authentication, the user can generate an SSH key pair and send root the public key for inclusion in ~/.ssh/authorized_keys.

I have just finished a howto as to how to set up a local smtp server to send locally sent mail to the internet. It uses gmail's smtp server to send out.
It will also recieve your google mail and forward it to a local accout.
This is my first time using postfix and fetchmail, and my first time writing a how-to of any consequence, so please comment!

The how-to can be found at www.sandmines.org/howtos

How-To: Adding Sessions to Dtlogin in Solaris (no replies)

ezod — Thu, 26 Apr 2007 14:46:39 -0400

November 14, 2002

Description

This document describes how to add custom window manager and desktop environment X Window System sessions to Dtlogin in Solaris 9 with CDE 1.5 (which includes the Dtlogin session manager). Having some experience setting up X sessions (using .xinitrc, for example) is helpful and recommended.

Procedure

Create /etc/dt if it does not exist already (this is to ensure files are not overwritten by patches or upgrades). Make a subdirectory "config" here and create the following files owned by root:other:

755 Xinitrc.SESSION
755 Xsession.SESSION
755 Xsession2.SESSION

Where SESSION is the name of the session you wish to create (e.g. GNOME-2.0, WindowMaker). Also, create a subdirectory "C" and a subdirectory "C/Xresources.d". Create the following file in this directory:

644 Xresources.SESSION

Now, fill in these 4 files with the text below, customizing where necessary (indicated by italicized text).

Xinitrc.SESSION

Creating the Logo File

This is a 237 x 237 pixel XPM format file (preferably 256 colors, otherwise it will not work on 8-bit or pseudocolor displays). Put this file in /usr/dt/appconfig/icons/C. Rename it with the extension .pm but do not include this extension in the "LogoFile" string described in the Xresources.SESSION file. For example, if you name your logo file Wmlogo.pm, simply enter "Wmlogo" in Xresources.SESSION.

After you have completed these steps, your custom session should be up and running. For the sake of completeness I included resources for the X Window System in the session files (colors, etc.), which can be customized to your taste for each session.

This method has been tested and works on Solaris 9 on the UltraSPARC architecture with CDE 1.5, with GNOME 2.0, WindowMaker 0.80.0 and Blackbox 0.65.0.
