Delete the existing printer:

Open a web broswer and wet to CUPS management URL: http://localhost:631 -> Administration -> Manage Printers, then deleted the MFC printer.

Followed these instructions and downloaded: 

mfc5860cnlpr-1.0.0-9.i386.deb
mfc5860cncupswrapper-1.0.0-10.i386.deb

Installed:

dpkg -i mfc5860cnlpr-1.0.0-9.i386.deb
  Produces errors - these can be safely ignored:
    mkdir: cannot create directory `/var/spool/lpd/mfc5860cn’: No such file or directory
    chown: cannot access `/var/spool/lpd/mfc5860cn’: No such file or directory
    chgrp: cannot access `/var/spool/lpd/mfc5860cn’: No such file or directory
    chmod: cannot access `/var/spool/lpd/mfc5860cn’: No such file or directory
 
dpkg -i mfc5860cncupswrapper-1.0.0-10.i386.deb

Printer was now listed in printer list and just worked after that.

<Directory /var/www/repo>
    AuthType Basic
    AuthName "Password Required"
    AuthUserFile /etc/apache2/passwords/repo
    Require valid-user
</Directory>

Create auth user password file:

htpasswd -c /etc/apache2/passwords/repo repouser

Restart apache.

Create repo:

yum install createrepo # or equivalent
mkdir /var/www/repo
cp *.rpm /var/www/repo
createrepo /var/www/repo

To use the repo, on the client system in /etc/yum.repo.d/<reponame>.repo, have:

baseurl=http://repouser:password@server/repo

Here is the setup:

• Evolution mail client, running on Ubuntu 7.04 Feisty Fawn
• Openldap server running on CentOS 4.4

First the facts, then the details…

Use

• BindDN -> uid=sam,ou=users,dc=ombwa,dc=org
• BaseDN -> ou=Sams,ou=address books,dc=ombwa,dc=org

Setup

• Copied evolutionperson.schema from /usr/share/evolution-data-server-1.10/ to my LDAP server /etc/openldap/schema
• Write the following slapd.conf (original comments/examples ommitted for brevity):

#
# See slapd.conf(5) for details on configuration options.
# This file should NOT be world readable.
#
include		/etc/openldap/schema/core.schema
include		/etc/openldap/schema/cosine.schema
include		/etc/openldap/schema/inetorgperson.schema
include		/etc/openldap/schema/nis.schema
include		/etc/openldap/schema/evolutionperson.schema

• Restarted LDAP server.
• Setup the tree by running the following LDIF file through

ldapadd -x -D "cn=Manager,dc=ombwa,dc=org" -w -a -f ''

To be honest I did half of it with PhpLdapAdmin – you can tell those entries because of the vestigial ”top” objectClass:

dn: dc=ombwa,dc=org
objectClass: dcObject
objectClass: organization
dc: ombwa
o: ombwa.org
 
dn: ou=users,dc=ombwa,dc=org
objectClass: organizationalUnit
ou: users
 
dn: uid=sam,ou=users,dc=ombwa,dc=org
uid: sam
userPassword::
objectClass: account
objectClass: simpleSecurityObject
 
dn: ou=address books,dc=ombwa,dc=org
objectClass: organizationalUnit
objectClass: top
ou: address books

ou: Sams
objectClass: organizationalUnit
objectClass: top

Explanation

Initially whenever I started locking down the ACLs at all, Evo would grey out most or all of the fields in the contact form. Clearly it wasn’t happy with the schemas that it could find on the LDAP server. Googling led me to discover the evolutionPerson objectclass, but the picture got clearer when I downloaded and examined the source:

sudo apt-get source evolutuion
sudo apt-get source evolutuion-data-server

In evolution-data-server-1.10.1/addressbook/backends/ldap/e-book-backend-ldap.c it says:

/* the objectClasses we need */
#define TOP                  "top"
#define PERSON               "person"
#define ORGANIZATIONALPERSON "organizationalPerson"
#define INETORGPERSON        "inetOrgPerson"
#define CALENTRY             "calEntry"
#define EVOLUTIONPERSON      "evolutionPerson"
#define GROUPOFNAMES         "groupOfNames"

I’m not doing calendaring yet, so I ignored calEntry. Everything but evolutionPerson was installed by default. After much Googling it turns out evolutionPerson schema is installed at with Evolution, at /usr/share/evolution-data-server-1.10/evolutionperson.schema. I copied this to my LDAP server /etc/openldap/schema and added a line for it to slapd.conf.

This still didn’t help, however, which the ACLs issue. After reading most of LDAP for Rocket Scientists I figured out what is going on. There is an “uber-object” called the RootDSE that contains meta-information about what the LDAP server serves. It has an object under it called Subschema that allows the caller to see all the classes the LDAP server supports. Evolution attempts to access these before authenticating, so you must have ACLs to support that. Ironically the example ACLs in the top of the slapd.conf set this up.

Much shenanigans with disk drives, not ubuntu’s fault.

Updated system.

Desktop Effects

Enabled this, which required installation of nvidia proprietary driver (useful for multiple monitor support in a sec).

Dual Monitor Support

After reading this and this, did this:

gksudo nvidia-settings
# -> X Server Display Configuration
# Selected disabled monitor.
# Enabled it (1600x1200 was automatically selected).
# Apply
# Save to X Configuration File -> /etc/X11/xorg.conf 

Ruby

Using synaptics package manager, installed:

• ruby (pulled in ruby1.8)
• rubygems (ri -> irb1.8 libgems-ruby1.8 libopenssl-ruby1.8 libreadline-ruby1.8 rdoc1.8)
• ri (needed for symlink)

For building extensions:

• ruby1.8-dev, build-essentials

sudo gem install --include-dependencies rails
# Installed rails-1.2.3 activesupport-1.4.2 activerecord-1.15.3
# actionpack-1.13.3 actionmailer-1.3.3 actionwebservice-1.2.3
sudo gem install rake

Subversion

Using synaptics package manager installed:

• subversion
• rapidsvn
• libsvn-ruby

MySQL / PHPMyAdmin / PHP / Apache2

Using synaptics package manager:

• phpmyadmin, which pulled in PHP and Apache2.
• mysql, which pulled in both the client and server.

MySQL server default password is blank.

sshd

Installed “ssh” which pulled in openssh-server (openssh-client already installed) so I could move things from my notebook to the desktop.

Desktop Effects

Desktop effects “Workspaces on a Cube” effect stops working if you ever try to modify settings after initially turning them on. Here is a fix https://bugs.launchpad.net/ubuntu/+source/desktop-effects/+bug/102309

1. Open the Desktop Effects window
2. Right Click on the Switcher
3. Left Click on preferences
4. Change the Number of Workspaces to 4
5. Enable Desktop on a Cube
6. Close the Desktop Effects window

Gaim w/SILC

Standard copy of GAIM for Ubuntu is missing SILC support. Here is now to recompile it with support:

sudo apt-get source gaim
sudo apt-get build-dep gaim
sudo apt-get install libsilc-1.0-2-dev
cd gaim-2.0.0+beta3.1
./configure
make
sudo make install

Then run it out of /usr/local/bin

• Ubuntu 7.04 Feisty Fawn, 2.6.20-16-generic
• vpnclient-linux-x86_64-4.8.00.0490-k9.tar.gz (got from work)
• Rackable.pcf

The package is broken wrt this Linux distro. A guy by the name of Alexander Griesser keeps creating patches to fix it. Here is the lastest on at the time of writing http://tuxx-home.at/archives/2007/05/29/T16_34_26/. He provides instructions too:

Unpack vpnclient sources:
 
 1. Untar the VPN Client
 # tar xzf vpnclient-linux-4.8.00.0490-k9.tar.gz
 
 2. Download the patch
 # wget -q http://tuxx-home.at/projects/cisco-vpnclient/vpnclient-linux-2.6.22.diff
 
 3. Change to the vpnclient directory
 # cd vpnclient
 
 4. Apply the patch
 # patch <../vpnclient-linux-2.6.22.diff
 patching file frag.c
 patching file interceptor.c
 patching file IPSecDrvOS_linux.c
 patching file linuxcniapi.c
 patching file linux_os.h
 
 Now the patch has been applied and you can safely install the client
 #./vpn_install

Then put Rackable.pcf in /etc/CiscoSystemsVPNClient/Profiles/

Instead of rebooting:

sudo /etc/init.d/vpnclient_init

Then to connect:
It seems it will always use the first ethernet interface, so if that doesn’t go anywhere, you have to disable it:

 sudo ifconfig eth0 down
 sudo vpnclient connect Rackable

cd
tar xvfj linux-2.6.20.tar.bz2 
cd linux-2.6.20/
make clean
make mrproper
cp /boot/config-2.6.9-42.ELsmp .config
make menuconfig
   # set XFS support to M
make -j6 all
make modules_install
make install
# reboot

-j6 refers to degree of parallelism. They recommend 2x # of processors. I like 1.5x.
