Problem adding Windows 2003 server to 2000 Active directory

When trying to add a Windows 2003 server to a 2000 domain, adprep would fail with this error:

F:I386>adprep /forestPrep

ADPREP WARNING:

Before running adprep, all Windows 2000 domain controllers in the forest should
be upgraded to Windows 2000 Service Pack 1 (SP1) with QFE 265089, or to Windows
2000 SP2 (or later).

QFE 265089 (included in Windows 2000 SP2 and later) is required to prevent poten
tial domain controller corruption.

For more information about preparing your forest and domain see KB article Q3311

Firefox fullscreen kiosk machine

Update (2 Dec 2005): kiosk extension is broken, I'm now using a hacked browser.jar (version 1.0.7), I made a few changes to xinitrc-common as well Simple kiosk implementation, not entirely thorough, but enough for our purposes. Machine boots and gdm logs into a user without a password, firefox starts fullscreen and opens our homepage. Simple to implement.

Replacing selinux policy

Make a backup and set the security context:

[root@surrey policy]# mv /etc/selinux/targeted/policy/policy.18 /etc/selinux/targeted/policy/policy.18.orig
[root@surrey policy]# cp new/policy.18 /etc/selinux/targeted/policy/
[root@surrey policy]# chcon system_u:object_r:policy_config_t /etc/selinux/targeted/policy/policy.18
[root@surrey policy]# /usr/sbin/setfiles -q -c /etc/selinux/targeted/policy/policy.18
/etc/selinux/targeted/contexts/files/file_contexts
[root@surrey policy]# load_policy /etc/selinux/targ

SELinux targeted preventing gnome-volume-manager from automounting filesystems

Symptom:

[user@surrey ~]: gnome-volume-manager ** (gnome-volume-manager:10207): WARNING **: manager.c/912: failed to initialize HAL!

Generate policy rules using audit2allow

[root@surrey ~]# audit2allow -i /var/log/messages allow initrc_t unconfined_t:dbus send_msg; allow unconfined_t initrc_t:dbus { acquire_svc send_msg };

Install policy source rpm

[root@surrey ~]# yum install selinux-policy-targeted-sources

Add local rules to local.te

[root@surrey ~]# pushd /etc/selinux/targeted/src/

Displaying international characters in Firefox (installing unicode fonts in fontconfig)

Using unicode fonts is the easiest way to properly display hindi, arabic, hebrew and other non latin languages. We install the unicode fonts in a local directory and then tell fontconfig to look in that directory. Edit /etc/fonts/local.conf



/usr/ias/share/fonts/fc

Then tell fontconfig to rehash it's tables

[root@host] # fc-cache

Check that your new font is there

[root@host] # fc-list |grep

Xnewt dying on SunRay 3.0

After modifying gdm.conf we noticed that Xnewt would not start properly on occassion. Xnewt was not ignoring the vt[0-9] command line option sent to X to specify a virtual console on which to run. We removed this from the command line sent to Xnewt and renamed Xnewt to Xnewt.sun

pushd /usr/X11R6/bin
mv Xnewt Xnewt.sun
echo  EOF >Xnewt
#!/bin/sh

XFIX=`echo $@ |sed -e's/vt[0-9]*//'`
echo `date`: ARGS=$@ XFIX=$XFIX >>/var/log/Xnewt

exec Xnewt.sun $XFIX -fp unix/:7100
EOF
chmod 755 Xnewt
popd
