All the unix philosophy really boils down to one iron law, the hallowed ‘KISS principle’

just replaced horde with telaen webmail on one server

horde install was insecure (old and buggy and i couldn't upgrade easily ) and needed special chrooted apache server (complex system to maintain) with special compiled php (imap extensions)

all is needed for telean is php ;) KISS

and works from first time , like ubuntu

redhat 7.3 -> fedora core 6 upgrade path

On legacy servers where rh (7.3 or 9) is installed it  can upgraded with yum to
an secure supported distro (fedora core 1->2->3->4->5->6)
I guess it's easier to install ubuntu or debian stable ....

goodbye firefox and thank you for all the bugs

[ED: It's the attitude stupid! it's all about attitude (think of Mozilla Corp going MS route - we hate the corpo not the products like ie7 or dotnet) , i agree with him i have already installed konq and it looks small and speedy , i also use opera, epiphany as alternative browser, for email i will test mutt and evolution ]
I had been thinking of leaving firefox entirely for a long time (I had already traded thunderbird for mutt last year), mainly due to its huge memory print (I like to navigate with more than 20 tabs at the same time), its slowliness and a growing dislike of the mozilla attitude, especially since the creation of the Mozilla Corporation.

Ubuntu Jesus Christ Edition

Six-years ago, there was a hoax Linux: Jesux, the Linux distribution for Christians. That was a joke. Today, it's real. In fact, there are several Christian Linuxes. Perhaps the most well-known of these is UbuntuCE (Christian Edition), which is built on top of Ubuntu 6.06.1 LTS.

Christian Linux, and it's not a joke this time

debian recovery status

i have created the partitions on new drive and formated them (with fdisk)

/dev/hdb1 6.5G 3.5G 2.7G 57% /home/ubuntu/mnt/root
/dev/hdb5 30G 18G 11G 64% /home/ubuntu/mnt/opt
/dev/hda1 9.2G 3.6G 5.2G 41% /home/ubuntu/mnt/rootnew
/dev/hda3 56G 6.2G 47G 12% /home/ubuntu/mnt/optnew

now I'm waiting cp to finish
$cd /home/ubuntu/mnt/opt
$cp -rp * /home/ubuntu/mnt/opt

/dev/hda1 is the new root partition (/boot dir is there too)
all i did to install grub was
sudo grub
root (hd0,0)
setup (hd0,0)
quit

after that reboot with new driver
black cats and western digital
yesterday some bad blocks (or maybe is the hdd overheating > 50C) started to be logged in the console
it's /dev/hda

So today i have an plan to move the old drive (40G) to a new one (80G)
1.I will create an new partitions ext3 and swap
2.I will copy old drive data on the new drive
3. boot with an live cd and install grub on boot following this guide
4.reboot

if all ok add the drives that are used for raid

backup plan : i will use dd

apache tunning part 3 (debian, *buntu)

Now i searched for files with .shtml extension , there was no file and in server-info cofiguration was empy for mod_include

So this one is now disabled http://httpd.apache.org/docs/1.3/mod/mod_include.html
apache performance part 2 (ubuntu/debian/linux)

i have made KeepAliveTimeout 5 and found that mod_mime_magic is not used and it does have some performance penalties .

"This module is not for every system. If your system is barely keeping up with its load or if you're performing a web server benchmark, you may not want to enable this because the processing is not free."

Also in production is good to disable mod_status and mod_info (mod_status is called for every request for getting unix time)

I have read the lighttpd vs apache thread and seems that apache 2.2 is quite fast on php requests.
For static content or flash movies lighttpd is quite fast (youtube and wikipedia are 2 examples)

Mount Remote SSH Filesystem with FUSE
in ubuntu or debian

is good to mount thousands of servers in your home (secure way)

the only bug i see is that my servers has 7.5T of free space ! no way (there are only a few gigs there)

Filesystem Size Used Avail Use% Mounted on
sshfs#foobar@example_server: 7.5T 0 7.5T 0%


the rest is working transparently without problems (creating and deleting files)
and is waaaaay better than samba or nfs or whatever
quad core amd/intel road map confusing ?
read this article on quad core future at both companies

if you don't want to wait an year for systems with >4cores
then there is T1,T2 based on opensparc and ubuntu works on it

Another option is mips64 with 4-16 cores (firebird is working on mips cores thanks to the siemens port)

so firefox is an successful project that is on top

I have seen it on debianhelp.co.uk apache optimization howto

ps: php is really fat (~22Megs sometime if compiled with all kind of options)

Monday, October 09, 2006

Who has the most impressive facial hair in the Open Source community?
optimize apache for speed (in ubuntu)
I usually compile/enable only the very basic modules for apache (httpd core and php)
but if you have an production sever you can check and disable modules that are not used
You can find them by looking in the server-info area in apache (http://localhost/server-info)

Here is the basic list that is left after cutting the fat :

mod_php4, mod_ssl, mod_so, mod_auth, mod_access, mod_rewrite, mod_alias, mod_cgi, mod_dir, mod_autoindex, mod_include, mod_info, mod_status, mod_mime, mod_mime_magic, mod_log_config, mod_vhost_alias, http_core

If there is more need for speed you can cut more

and use only http_core,mod_php4,mod_mime, mod_mime_magic, mod_log_config,mod_vhost_alias,mod_ssl
basically you reduce the apache to an small core similar to lighttp web server.

ps: i like the list of sites powered by lighttp

debian on various emulated machines - roundup
it might be useful for porting firebird on them

I booted debian on 3 machines from bellow (didn't tested mipsel yet)
mipsel - http://www.pps.jussieu.fr/~letouzey/emul_debianmips.en.html
arm - http://www.aurel32.net/info/debian_arm_qemu.php
powerpc - http://digg.com/linux_unix/How_to_run_Debian_PPC_via_Qemu_Easy_way
s390 - http://digg.com/linux_unix/Debian_image_for_Hercules_s390_emulator_available

Left to do (test on)

* Alpha
* HP PA-RISC
* Intel IA-64 (seems that hp does have one itanic emulator)
* Motorola 680x0
* SPARC (qemu can be used for booting maybe)

r00t login into Debian Hercules (s390 emulator)

you need to prefix the debian commands with "." :

A Linux boot sequence takes place that looks more-or-less as it does on Alpha, Intel or other platforms. Interaction here is still via the virtualised HMC, where the rule is that any commands prefixed by a dot "." are passed through to the mainframe session and anything else is interpreted as an HMC command.

Quote from http://en.wikipedia.org/wiki/Hercules_emulator

Here are my results
.cat /proc/cpuinfo
cat /proc/cpuinfo
vendor_id : IBM/S390
# processors : 1
bogomips per cpu: 50.68
processor 0: version = FD, identification = 002623, machine = 3090
