D-Link DGE-530T 10/100/1000 Gigabit Ethernet

How to install D-Link DGE-530T 10/100/1000 Gigabit Ethernet driver
on CentOS-4.4

/Linux driver/install-8_23.tar.bz2 from CD in D-Link box,
note: there is also a half-height bracket in the box.

make sure the link
ln -s ... /usr/src/linux is ok, especially if a new kernel is installed
When I built the driver :
ls -ltrd /usr/src/linux
lrwxrwxrwx 1 root root 37 Oct 27 21:26 /usr/src/linux -> /usr/src/kernels/2.6.9-42.0.3.EL-i686

/etc/modeprobe.conf - replace sky2 driver with installed sk98lin
...
alias eth0 forcedeth
alias eth1 sk98lin

Quoted from:

http://www.phoronix.com/lch/?k=entry&l=53&t=D-Link%20DGE-530T%2010/100/1000
I installed the sk98lin driver in the supplied CDROM.

I followed the installation instructions in the README file in /Linux driver/install-8_23.tar.bz2. I did not follow the procedure in /Linux driver/sk98lin.txt - I suspect that is for an older driver version.

I loaded the driver module and it worked first time.

Growing a raid5 array

Grow a raid5 array from 3 disks to 4.

mdadm - lvm(2) - evm - extfs

A- Growing a raid5 directly
get mdadm 2.5.2 or above
-found http://www.cse.unsw.edu.au/~neilb/source/mdadm/RPM/mdadm-2.5.3-1.i386.rpm
confir kernel >2.6.17

first create 4 devices in vmware. /dev/sd[bdce]1
mdadm --create --verbose /dev/md0 -l5 -n3 /dev/sdb1 /dev/sdc1 /dev/sdd1
# how big does the backup file need to be?
mdadm --grow /dev/md0 -n4 --backup-file=/tmp/raidbackup
mdadm -a /dev/md0 /dev/sde1

Then redo this with a filesystem on /dev/md0, or better ext3fs over lvm over /dev/md0

B- Alternatively using multiple raid5 pv's we can simply grow each pv independantly:
* pvmove /dev/md3 # Move all data off of /dev/md3
* vgreduce vg /dev/md3 # Remove /dev/md3 from the volume group
* pvremove /dev/md3 # Remove the LVM signature from /dev/md3
* mdadm --stop /dev/md3 # Stop the array
* mdadm --zero-superblock /dev/md3 # Remove the md signature from the disk
* mdadm --create /dev/md3 --level=5 --raid-devices=4 /dev/hda3 /dev/hdc3 /dev/hde3 /dev/hdg3 # Create the new array
* pvcreate /dev/md3 # Prepare /dev/md3 for LVM use
* vgextend vg /dev/md3 # Add /dev/md3 into the array

---- found this enabling note---
http://www.gagme.com/greg/linux/raid-lvm.php
For those now reading this, you can actually expand a raid 5 array with mdadm for software based raid in linux. At least as of kernel 2.6.17 and mdadm 2.5.2 it is possible. One easy way to stest this is to create 4 files with dd, I created 4 100MB files named raidfile[1-4]. Next, use losetup to set them up as loop back devices, I used loop[0-3]. To create the initial array do:
mdadm --create --verbose /dev/md0 -l5 -n3 /dev/loop0 /dev/loop1 /dev/loop2
The array should now be initializing, when it is finished, increase the number of raid devices in the array by issuing the command:
mdadm --grow /dev/md0 -n4 --backup-file=/tmp/raidbackup
This part requires a backup file in case power is lost during the reordering of data, this backup file has to be used to assemble the raid array in that case.
Next, to add the other drive to the array use:
mdadm -a /dev/md0 /dev/loop4
the new drive will then be added to the array with no data lose hopefully. During my testing it has worked flawlessly so far, but as for using it on a production box its probably not recommended unless you have backups. You do keep backups correct?

galo on drupal and gallery2

New implementation choice for galo:
vmware running ubuntu server with drupal and gallery2.
Here is the logo image:

NSLU2 dl-slug

After a part swap from linksys, which turned out to be another Power supply failure...

Restoring the slug:
-confirm working
configure : ip 192.168.5.200
Server Name dl-slug
Workgroup : SOLO
Lang Support: Western Europe/Latin-1

Before updating to unslung firmware
test telnet into redboot as in
http://www.nslu2-linux.org/wiki/HowTo/TelnetIntoRedBoot
I used the following (Third manual method):
while ! ping -W 1 -c 1 192.168.0.1 2>&1 >/dev/null; do true; done && telnet 192.168.0.1 9000

From the readme : Unslung-6.8-beta-README.txt
I think It will be better to upgrade to linksys V23R63 first.
Having to do with the unslng disk being in USB port1 or port2.
And I intend putting the drive in port1.
But if I unsling a brand new drive, Then I will do as sugessted and unsling to port2.

HOLD EVERYTHING, will redo this as per readme with a brand new drive.....

Checksums for reference...

-update to latest firmware : NSLU2_V23R63.bin

RPC options

Results:
Basic transport is workable now.
For initial tests php-o-lait will be simpler, (requires php 4.3 (.1)+ (not boole)

JSON-RPC
Server side -
JSON.php wrapped by me
php-o-lait includes JSON.php , and rpcproxy classes
json-rpc-java-1.0

Client side
php-o-lait rpcproxy classes
Hand written code in HttpPostTest
including cookie tracking.

Impedence mismatch: Types!
If php is in the chain, whoe dow we adapt the class hinting scheme from java client:
remove it from the source by hand ?
Implement Objects in php ?

Other transports:
REST, XMLRPC, SOAP
JAX-RPC -> supplanted by JAX-WS 2.0 (which supplants JAX-RPC), JAXB 2.0, and SAAJ 1.3.

What about http://xins.sourceforge.net/
handles all three: REST, XMLRPC, SOAP

for xmlrpc :
implementation list : http://www.xmlrpc.com/directory/1568/implementations
top candidates for java:
http://ws.apache.org/ or http://ws.apache.org/xmlrpc/index.html
http://xmlrpc.sourceforge.net/ (redstone , was Marquée)
top candidates for php: not yet reviewed
There is already a module in php :php-xmlrpc (on euler,abel,rack2)
article describing this extension :
http://www.devshed.com/c/a/PHP/Using-XMLRPC-with-PHP/
this is the xlmrpc-epi (epinions extension)
http://keithdevens.com/software/xmlrpc
http://scripts.incutio.com/xmlrpc/
http://phpxmlrpc.sourceforge.net/ (has some json stuff too, had trouble making it work ?)
but maybe that was on boole)

either
-translate ./heads/aviso-core/conf/internationalization by adding : 中国 suffix/prefix whith a style sheet. i18n-zh.xsl
-modify localization.xsl to produce zh, unicode escaped properties files...

Apply a global servlet filter to change default encoding type...

Change database encoding to utf-8 (mysql4) try users table first.

--------------------------------------------------------
-- What I've learned: from static page experiments
The browser detection seems to hinge on the jsp directive:
<%@ page language="java" contentType="text/html; charset=UTF-8" %>

which affects the http Content-Type header:
Content-Type: text/html;charset=UTF-8
whereas the default is
Content-Type: text/html;charset=ISO-8859-1

The html/head/meta/@content doesn't seem to affect the browser charset selection:
<meta content="text/html; charset=UTF-8" http-equiv="content-type">
when the content type is set in the http response header, which is always the case with jsp pages.
You can observe the headers with:
wget -S -O - http://boole:8080/unique/china-UTF-8.jsp

Zabbix re-born

Put zabbix back on its feet.
-reduce the frequency of polled data
down to 5 minutes ( 15 would break slave rule. )
-add new hosts
viau, wdel, unique (btna)

check history table on zabbix database on rack3:

select m.host, count(*) as num from history h left join items i on i.itemid=h.itemid left join hosts m on i.hostid=m.hostid where h.clock>unix_timestamp(now() - INTERVAL 10 minute) group by m.hostid;

new infrastructure heatbeat.
