[-> 7.1] mod_php3 in ML 7.0 and 'high' security level

(Contributed by Steven Mc Farling, edited)

"I have found it is the "security level" that made mod_php not work. If I install (all other things the same) with a security level of "high" the following is required to get php to work.[...]

1. Type the following at the command prompt to ensure the mod_php3 rpm is installed on the machine:

   rpm -qa | grep php3

   If mod_php3-3.0.13-6mdk is listed, go to step 2. If NOT, then install the mod_php3 rpm by doing the following:

   1. put Mandrake 7.0 CD in CDROM
   2. type: mount /mnt/cdrom
   3. type: cd /mnt/cdrom/Mandrake/RPMS

   4. type: rpm -i mod_php3-3.0.13-6mdk

2. Add the lines with the ** in front of them to the '/etc/httpd/conf/httpd.conf' file. I will put the line before the change to help insure you put the lines in the correct place:

   LoadModule setenvif_module modules/mod_setenvif.so
**LoadModule php3_module /usr/lib/apache/libphp3.so
AddModule mod_setenvif.c
**AddModule mod_php3.c
Include conf/vhosts/vhost0.conf
**Include conf/addon-modules/mod_php3.conf

3. Restart the web server by typing:

   /etc/rc.d/init.d/httpd restart

4. You should see

   Shutting down http: [ OK ]
Starting httpd: [ OK ]"

Yves Lucet adds:

"To use php on apache I had to add the following lines to '/etc/httpd/conf/httpd.conf' (I am using Linux Mandrake 7.1):

#see http://www.mandrakeuser.org/troubles/tquick4.html
Include conf/addon-modules/mod_perl.conf

LoadModule php3_module modules/libphp3.so
AddModule mod_php3.c
Include conf/addon-modules/mod_php3.conf

So the quick tip should be completed by checking that mod_perl is available, if it is not add the first Include line before loading php3."

[= 7.0] "No more processes at this runlevel" during boot

(Contributed by Al Chou, edited)

"I ran /etc/security/msec/init.sh custom and answeredyes to allow root logins at the console. A typographic bug at the beginning of line 53 of '/etc/security/msec/init-sh/custom.sh' [msec-0.9] then caused '/etc/inittab' to be zeroed out, which upon reboot caused the system to ask what runlevel I wanted to use and then proceed to say, No more processes at this runlevel.

[...] Over the weekend I remedied this by reinstalling from scratch (I didn't know any better), but at an early point I did discover that /etc/inittab had zero bytes in it.[...]

I finally gleaned enough from Deja and the Linux System Administrator's Guide to piece together what to do. Here it is:

1. Upon booting, tell LiLo to use linux init=/bin/sh.
2. The file system will be mounted read-only, so remount it in read-write mode: mount -o remount,rw /dev/hda6 /
3. Now restore your '/etc/inittab' from the backup copy (assuming here you have one called '/etc/inittab.bak'):
   cd /etc
cp inittab.bak inittab
4. CTRL-ALT-DEL to reboot the system, which should come up normally.

P.S. The bug in '/etc/security/msec/init-sh/custom.sh' is fixed in the current version of msec that can be found in the Mandrake cooker directory."

[-> 7.1] GNU/Linux doesn't detect more than 64 MB of RAM

If you've got MS-Windows installed, check if it detects the correct amount of system memory. If not, there is something wrong with your memory modules.
Current GNU/Linux kernels have some difficulties with certain BIOS'es, read this message from the linux-kernel mailing list for an explanation.
The only switch that might help you is supplying the correct amount of RAM either on the boot prompt or via '/etc/lilo.conf'. At the boot prompt, type

linux mem=[size in MB]M
(e.g. linux mem=96M, if you have 96 MB RAM).

If this works, add it to your '/etc/lilo.conf', by changing the stringappend="" to something like this:append="mem=96M"
In GRUB, use something like

title linux
kernel (hd0,0)/boot/vmlinuz root=/dev/hda1 mem=128M

[-> 7.1] Acrobat Reader Crashes (Segfault)

Make sure you have version 4.05. But even that version crashes when used at a color depth of 24bpp. Either use 'xpdf' for displaying PDF files or change the color depth of your display.

[= 7.1] ISDN doesn't work

Due to a packaging error, the 'isdn4k-utils' package in LM 7.1 does not install correctly. Either use the package from 7.0 or get the updated package (isdn4k-utils-3.1b7-6mdk), e.g. via the RPM Repository.
