You can try to find the packages which have a "php" file :
dpkg -S php

Or you can look the files installed by a given package :
dpkg -L php5-cgi

finally, you can update the file database with "updatedb" and then query
the database with "locate php"

But I think there is something called "php5-cli" (for Command Line
Interface" :
http://packages.debian.org/etch/php5-cli

Check the frequencies (FSB and core) in the BIOS, your Mother Board or CPU
could be overclocked and become too hot to work.

Install something to monitor the thermal and fan sensors on the CPU (and
the disks). It might be because of CPU too hot, a deffective fan.

Look in the SMART information from your disks. If a disk with a SWAP
partition fails, it might freeze the kernel too.

It can also be because of a power weak. Too much power asked by the
DVD+Disks + Video +... and not enought for the CPU. Often, there is a
limit, even if the manufacturer says "2 rails".

But, dont ask me why the mouse pointer still worked.

You should try to use "make-kpkg ... clean", and then use either the
environnement variable or the command line option to ask make-kpkg to
patch the kernel (with the patch you want), to ask you for the menuconfig
instead of silentoldconfig and to compile the package as you want.

The exact options and environnement variables are in the make-kpkg man
page, if I'm right.

You will eventually have to check/adapt the /sD/etc/fstab file if the
partition scheme changed.

You will have to reinstall the bootloader (grub or lilo) either in the MBR
(Master Boot Record) or in the active partition BR (Boot Record).

Do you have the acpi module loaded in kernel ?

I have similar problems (for halt) and solved it with the acpi module. It
might be the apm module too.

If acpi is not loaded, try :
modprobe acpi
then
shutdown -r now

If it works, add acpi in /etc/modules or install the acpi package

You can use the package "swatch" to colorize the logs.

Hum... Because ! ;-)

In fact, first, I used to do this, because I seldomly use all files in a

because there was a "ls" in the original problem and third because I did 
not optimize the command ;-)


I'm sure it is possible to replace the "mkdir -p xxx; rmdir xxx" with 
something better. For exemple in the problem, it was not needed, a

First, compute the dirname to put the file in.
Second, create a directory corresponding to the full destination path
including the filename to create the parent directory if it does not
exists
Third, remove the directory with the name of the file
Fourth, move the file

The command line includes "echo" for you to see what will be done. When
you want the job to be done, just remove the "echo" before mkdir, rmdir
and mv.

Hi,

You can also install the checkinstall package and use it to "reinstall"
your soft. It will create a debian package and you will be able to remove
it.

I just asked Google, it gaves me the following URL :
http://unix.derkeiler.com/Newsgroups/comp.unix.shell/2007-01/msg00175.html

So, you can create a /etc/bcrc file with the settings :
~ $ echo scale=2 > /etc/bc

add the appropriate environnement variable in /etc/environnement :
echo BC_ENV_ARGS=/etc/bc >> /etc/environnement

logout and login.

I only have a cygwin here, at work, but the environnement variable works
well as long as the init file exists.

Reasonable ??? for who ?
a client buying one, two or three apples, but no fraction of apples ?
a guy who needs 2 decimals to know how much VAT he will pay with his new
car ?
a trader who can need about 5 decimals
a physician who needs a lot more...

So, how much is reasonable ? 2 because you often use it for prices, 8
because much of real cheap calculators display 8, ... at least, with bc,
you can choose. You just have 4 keywork to remember : ibase, obase, scale
and last, most people can forget the ibase and obase, so there are only
two. You can even forget the "last" because you can recall the previous
lines with the "readline lib" and the "up" key (can you do that in your
GUI calculators).

But if you dont like it. it is OK, I can understand.

Just download the "HTML Tidy" and "webdevelopper" plugins in Firefox and
look the little icons. If they are green, the page is compliant to
standards, yellow : there are warnings and red : there are errors. You
will see that nearly every web site does not conform to the standards.
Even the simplier as the "alt" attribute in "img" tags. So, you can not

It is a real work to develop web pages which are fully compliant to W3C,
which show correctly in every browser (lynx, IE, firefox, chrome, opera,

it. The problem is that everyone thinks he can write a web page or a site

Ok, so you could use the second solution (as msttcorefont or
flashplayer-nonfree):
- postinst ask the user where the tar.gz file is
- if the user dont have it, postinst download it for him
- postinst installs the tar.gz in the right place and tracks the list of
files
- prerm delete the file tracked at the postinst stage.

So you do have a package (nearly empty) which installs the soft. The soft
is not included in the package but downloaded at install time, you can
remove the files installed and you can depend on this package.

Does it answer to your needs ?

You can not do that. It means that your package will rebuild the child
package everytime it is installed ??? Furthermore, where a package (yours)
is installing, the dpkg/apt database is locked to prevent another dpkg/apt
from modifying it. So you will not be able to do such a strange thing.

You should prepare a source package which use uscan or uupdate to check
for new version availlability. So, you just have to rebuild the package
each time the upstream release a new version. And push it in an intern
repository (instead of your current package).

If you can not embed the Java in your package (as Flash, for example),
your package will only download and install the Java files in the postinst
script and remove theses files in the prerm script.

Your problem is not different than all the packages built upon upstream
(non-debian) sources.

Hi,

I just pressed F1 and asked for DHCP. The first choice was Netsh commands
for DHCP. It seems that you can try :
netsh > DHCP > server localhost > dump
or
netsh > DHCP > server localhost > export

But I do not have access to a Windows DHCP server to try it

Hi,

You have two possibilities :
1 - Declare the RAID array during the install, give it a mount point, but
DO NOT format it ! ;-)
2 - Do nothing, just ignore the n individual drives, the RAID metadevice
and eventually (certainly) the LVM PV/VG/LV... After install, just add the
package "mdadm" (and eventually "lvm2"). At boot, it will automatically
detect the RAID MD and the LVM LV. You will just have to create the
mountpoints and to edit manually the fstab.

It works fine, I did it yesterday (solution 2) ! ;-)

Hi,

You certainly already have a SSH server running on the production server.
If you can have a root ssh connexion (without password, only with key
challenge), I can see two solutions by booting the test server with a
LiveCD :
- you can reformat the test server's filesystem, mount it and run the
following command :
  ssh [EMAIL PROTECTED] "tar cf - /" | (cd TestServerFSMountPoint ;
tar xvf - )
- you can only update the test server's FS with rsync, you mount it and
run something like :
  rsync -av --delete [EMAIL PROTECTED]:/ /TestServerFSMountPoint

Don't forget to update the files in /etc. You have to change all the IP
and host occurences :
- grep -r www.xxx.yyy.zzz /etc
- grep -r productionserver /etc

You can certainly automate the changes with the following commands :
- grep -r www.xxx.yyy.zzz /etc | cut -d: -f1 | xargs sed -i
's/www.xxx.yyy.zzz/aaa.bbb.ccc.ddd/g'
- grep -r productionserver /etc | cut -d: -f1 | xargs sed -i
's/productionserver/testserver/g'

Hi Pol,

You can use "dpkg --get-selections > packages.lst" to get the installed

Hi,

I use the Happy Hacking Keyboard (US QWERTY, 60 keys) and I am French, so
I very often need theses strange caracters with accents. I use the
"us_intl" layout in the xorg.conf file and I don't need to press AltGr.
The accent ekys are always dead, so I need to press two keys one after the
other to get all kind of caracters :
"'" + " " = "'"
"'" + "e" = "é"
"'" + "c" = "ç"
"`" + "u" = "ù"

It works with upper case and lower case letters, with a lot of accents ( ~
' " ` ) over (or under) nearly every caracter. It works directly in X, so,
without a WindowManager, with XFCE or any other WM (as long as it does not
reconfigure the mapping as Gnome does). And I use the same configuration
(console-data) on console.

You dont have to use a temporary file. You can try the following :
- NewLaptop : create partitions (ie hda1 for /boot and hda2 for /)
- NewLaptop : create the filesystems on the partitions (mke2fs /dev/hda1 ;
mke2fs /dev/hda3 )
- NewLaptop : mount the filesystems on /mnt as they will be (mount
/dev/hda2 /mnt; mkdir /mnt/boot ; mount /dev/hda1/ /mnt/boot)
- NewLaptop : run the following command to copy all the files
ssh [EMAIL PROTECTED] "tar cjf - --exclude lost+found --exclude /proc --exclude
/sys /" | (cd /mnt ; tar xvjf - ; mkdir proc sys)
- NewLaptop : chroot in /mnt (chroot /mnt)
- NewLaptop : mount /proc
- NewLaptop : install GRUB or LILO on the MBR (grub-install /dev/hda;
update-grub)
- NewLaptop : umount /proc
- NewLaptop : umount the filesystems (umount /mnt/boot; umount /mnt)
- NewLaptop : reboot

It SHOULD work

PS: The transfert might be twice compressed : one time with the tar's "j"
option and a second time by ssh

As you seem to be unable to have a physical access to the server, I
suppose you can not go to single user mode. If you try "init S" or "init
1", you will probably loose you network connection.

I would certainly try this :
1 - mount the "/" (root) partition a second time on a mount point (ie on
/mnt) as Linux can do this. On this second mount point, you will not have
the sub-filesystem "sdc1" mounted on /mnt/usr. So you will be able to
alter /usr on the root FS.
2 - rsync the bad /usr (sdc1) on /mnt/usr (it will theorically copy the
contents of /usr (sdc1) on /usr (root), behind the one mounted from sdc1
3 - if sdc hangs, reboot and resume from (1), it will resume the copy
4 - remove the "/usr" line in the fstab ;
5 - reboot (the sdc1 fs will not be mounted over /usr)

But this solution SHOULD work IN THEORY !!! I never tried it. someone
might have a better idea.

Hi,

You can use :
# ( cd /usr; tar cf - . ) | ( cd /mnt/newusr ; tar xvf -)

to do the copy, but as your disk will probably fail during the process,
rsync is a better choice as it can resume the copy.

I think you will certainly miss some files.

If I well understood, you have a Linux box at home with a limited Internet
quota and a windows box somewhere else without quota ?

If it is right, I think you could download from the unlimited access a DVD
ISO to burn. You will use this as a source for sources.list. You will have
a lot of other packages to install.

If you only need the apache2-mpm-prefork package and its depends, there is
a solution to get its dependencies tree, but I dont remember it (it can be
used to draw graphwiz graph, look for the work graphviz in the apt-cache
man page).

I use Mercurial instead of GIT, but it is very close. I use it under Unix
(Solaris and Linux) and Windows. And I use KDiff3 under Unix and Windows
too. It can do three-file merge, has color highlight and can also do
directory diff.

So, if Git can use it, I recommend KDiff3

If you forget the iptables rules, you can almost ever connect from a
client to a server with a public IP (not behind a NAT). But you can not
connect directly to a box behind a NAT. So, the only way to establish a
connexion is to initiate the connexion from the box behind the NAT.

Secondly, you can initiate a SSH connexion, but you will not have every
thing or a VPN to route all the network traffic. As I explained, you have
to initiate the VPN connexion from the NATted box to the other. After,
both boxes are on the same network (VPN).

Now, you have to protect the admin box from an attack initiated from the
NATted box (mother's). Because this box is unsure. So, you set iptables
rules on the admin box to filter every byte which comes from the NATted
box.

Then, you can still go on internet with you normal connexion, but you can
not use it to connect directly to the NATted box, as it is natted and it
does not have a public IP. But you can connect to it using the VPN because
you are both on the same private network. And you box is protected from
malware installed on the NATted box.

I hope I was clear with my explanations.

Hi,

When nothing write logs, syslog automatically write periodically a MARK in
the logs.

You can find this in the syslog man :
   -m interval
  The syslogd logs a mark timestamp regularly.  The default inter-
  val  between  two  --  MARK -- lines is 20 minutes.  This can be
  changed with this option.  Setting the interval to zero turns it
  off entirely.


It can help you to know when a system crashed.

Hi,

gparted can't connect to your X server. It is either because the server
refuse the connection (not allowed with xhost), or because the
environnement variable DISPLAY is not corretly initialized. So, you can
try :

Directly as user "za", with sudo (and a special line in /etc/sudoers) :
zara:/home/za$ sudo gparted

Or simplier, as root :
zara:/home/za$ xhost +localhost
zara:/home/za$ su -
zara:/home/za# DISPLAY=localhost:0.0 gparted
or
zara:/home/za# DISPLAY=localhost:0.0 ; export DISPLAY ; gparted

Hi,

You could use the group sticky bit :
- create a new group for each site (www-a, www-b, www-c)
  addgroup www-a
  addgroup www-b
  addgroup www-c
- add the www-data user (apache user) to the groups :
  adduser www-data www-a
  adduser www-data www-b
  adduser www-data www-c
- recursively change the permissions (note the sticky group bit on the
directories) on the sites :
  find /var/www/html/a-website.com -type f -exec chmod 664 {} \;
  find /var/www/html/a-website.com -type d -exec chmod 2775 {} \;
  find /var/www/html/b-website.com -type f -exec chmod 664 {} \;
  find /var/www/html/b-website.com -type d -exec chmod 2775 {} \;
  find /var/www/html/c-website.com -type f -exec chmod 664 {} \;
  find /var/www/html/c-website.com -type d -exec chmod 2775 {} \;
- recursively change the group ownership of each site :
  chown -R www-a /var/www/html/a-website.com
  chown -R www-b /var/www/html/b-website.com
  chown -R www-c /var/www/html/c-website.com
- add the developpers to each group :
  adduser deva1 www-a
  adduser deva2 www-a
  adduser devb1 www-b
  adduser devc1 www-c

Advantages : you can have multiple developpers on one site
Drawback : the apache user have a write access to the files.

You should consider a revision control system. The developpers push their
developpments in the repository and the sites are manually or
automatically synchronized with the repositories.

lokk for "quota" package. You will have to enable quotas on the filesystem
(if the Filesystem accept it) in the /etc/fstab file and remount the
filesystem. Then, you will edit the quotas with edquota and reboot the
server (easiest way to take everything into account and to initialize the
quotas).

For the bandwith, it is not simple. I dont know a simple solution for your

What kind of acces will he have ? If he can "ssh" into the serveur, you
can explore two solutions :
- a limited shell interpreter (partial solution)
- a jail (chroot)
If not (lock his account with "passwd -l user" and give him a "/bin/false"
shell), you can configure the FTP server to chroot him self.

- Install Samba on the server (the host with DVD)
- Configure the mount point
- Configure a samba share for the mount point
- Configure the share to execute pre and post scripts (a mount script and
a umount script)
- Connect the client (hosts without DVD) to the share, the DVD will
automagically be mounted on the filesystem shared and you will be able to
access it. It will be umounted after the last connection is closed.

Hi,

I am not sure to understand you problem :

- Do you want to remotely mount a remote DVD on the remote filesystem ?
This should work :
ssh [EMAIL PROTECTED] mount /dev/dvd /media/dvd

- Do you want to locally mount a remote DVD on the local filesystem ? You
have several solutions (sshfs, NFS, Samba, ...)

Francois

I'll welcome advice on whether it's the HDD about to die or whether the
interrupt/timed out messages indicate something else?


IMHO, that means you should begin to double check your backups. And 
secondly, if I were at your place, I would change the HDD ASAP.

Hi,

If you look into the email headers, you find these lines :

You should try to ask help, it will give you all the available commands.

Hi,

Did you have a look on the mini-box web site ? They seem to have boxes
designed specially for the Alix boards.

Have a nice day.
