enable subversion server come with Leopard

Mac Leopard actually come with subversion server and client that integrated with its own apache2.

Steps to enable it:

• create self-signed certificate http://www.tc.umn.edu/~brams006/selfsign.html or http://developer.apple.com/internet/serverside/modssl.html
  
• modify the /etc/apache2/httpd.conf to add the below:

LoadModule dav_svn_module libexec/apache2/mod_dav_svn.so
LoadModule authz_svn_module libexec/apache2/mod_authz_svn.so

• enable httpd-ssl.conf by removing the comment from the following line in /etc/apache2/httpd.conf:

Include /private/etc/apache2/extra/httpd-ssl.conf

• Add the following line at the end of file /etc/apache2/extra/httpd-ssl.conf but before the </VirtualHost>

DAV svn

SVNPath /opt/repos

AuthType Basic

AuthName "Authorization Realm"

AuthUserFile /etc/svn-auth-file

Require valid-user

• create the /etc/svn-auth-file using the following command to create user id. It will prompt for password twice

htpasswd -cm /etc/svn-auth-file

• restart apache by

/usr/sbin/apachectl restart

• mkdir the subversion repository, generate the first repository and change ownership of the folder to match with apache user

mkdir /opt/repos

svnadmin create /opt/repos

chown -R www:www /opt/repos

• test the access to subversion server using the https://127.0.0.1/svn/
• try with svn co https://127.0.0.1/svn/trunk --username

My Mac Pro - use 2 extra sata as as esata

The left is my Mac Pro bought in Feb 2008.

I read http://www.anandtech.com/mac/showdoc.aspx?i=2832&p=3.  This is a little bit outdate as it is for 2006 Mac Pro.

This is much easy now for 2008's Mac Pro. The heatsink cover can be easy removed as it is now put in place like Macbook MagSafe Connector.  There is no need to pull the memory cage back towards the rear of the case nor pushing the heat sink cover in the opposite direction to unlatch it as explained in the above url

The fan assembly can be removed by just two screws.  One attached it to the motherboard at the top right.  The other is hidden between plastic fan assembly and the heat sink (bottom right of the fan assembly after removing the heat sink cover).  The the picture below showing the hidden screw to loose the fan assembly and on of the magnet to attach the heat sink cover

Export NFS through Firewall

rpcinfo -p will list nfs ports used

copy the following from http://linux.derkeiler.com/Mailing-Lists/Fedora/2007-07/msg02399.html

1) You must have ports 2049 tcp+udp and 111 tcp+udp open in the nfs
server firewall to allow clients to talk to nfs and portmap, respectively.

2) There are a number of other daemons on the server, associated with
nfs, namely rpc.statd, rpc.lockd, rpc.mountd and rpc.quotad. These must
also be accessible to the clients. By default these start on random
ports, which the firewall couldn't care less about. So to allow clients
to get to the rpc services you must
2a) force the rpc services to start on pre-assigned ports of your
choice, like 4000 to 4003.
2b) open ports 4000-4003 tcp+udp in the firewall (or whatever
ports you used at (2a).


Now, here is how you do all this. You implement 2a by creating a file
/etc/sysconfig/nfs with the following contents:

STATD_PORT=4000
LOCKD_TCPPORT=4001
LOCKD_UDPPORT=4001
MOUNTD_PORT=4002
RQUOTAD_PORT=4003

Restart nfs.


The rest is opening ports into the server firewall, which is a separate
matter. On the server, something like

/sbin/iptables -I RH-Firewall-1-INPUT 10 -s 192.168.1.0/255.255.255.0 -p
tcp -m state --state NEW -m tcp --dport 4000:4003 -j ACCEPT

will insert a rule at position 10 (if 10 is the position you want) in the
RH firewall that opens the range 4000-4003 for incoming tcp connections
from the local network. Run then the above command again with udp instead
of tcp. Do the same (tcp+udp) for ports 111 and 2049. Finally, save the
new firewall configuration

/sbin/iptables-save > /etc/sysconfig/iptables # after backing up old
iptables first.

and restart iptables

/etc/rc.d/init.d/iptables restart

Fedora-install-media.repo

use autofs to mount the image

have the belowin /etc/yum.repos.d/Fedora-install-media.repo

metadata_expire=-1
gpgcheck = 0

baseurl = file:///mnt/disk/3/ (this line is required to autofs mount the device with the iso image)
file:///misc/Fedora8/ (use autofs to mount the iso for actual use)

Build my Linux Software RAID5 at home

It is great.

I create raid5 with 3 disk
then add one more disk by

mdadm --manage /dev/mdX --add /dev/sd?1
mdadm --grow /dev/mdX --raid-devices=4 (original is 3)

This will reshape at the back. Very slow but find the below to speed up

In Fedora 7, original value
cat /proc/sys/dev/raid/speed_limit_min ==> 1000
echo 100000 > /proc/sys/dev/raid/speed_limit_min

MBR fixes

MBR appears to be blank.
You can add an MBR to this device with
# cat /usr/lib/syslinux/mbr.bin > /dev/sdk

Sybase ASE on Linux FAQ - Fedora

Extract from the link below:

• Running ASE 12.5.1 on Fedora

Fedora is the new name of Red Hat's "consumer" releases (as opposed to their "Enterprise" releases).

ASE 12.5.1 requires a Java JVM to install. I downloaded mine from http://java.sun.com/j2se/1.4.2/download.html. There are some instructions on performing the JVM install at http://fedora.artoo.net/faq/#Java.

Next, the dataserver binary is linked with some older libstdc++.so libraries. To get these libraries you need to install compat-libstdc++-7.3-2.96.118.i386.rpm. This is available in the Fedora distribution.

Now you are ready to go ahead and install.

Note that the 12.5.1 installer doesn't create a "sybase" user for you, doesn't install any rc files, and doesn't edit /etc/ld.so.conf, so you'll have to do that yourself. Also remember to set the kernel.shmmax entry in /etc/sysctl.conf and run /sbin/sysctl -p before building a new server.
