admin — Wed, 25 Feb 2009 11:13:05 +0000

Questa è una guida per installare i VMWare Tools su Slackware 12.2

Questi sono i passaggi da seguire:

links "http://prdownloads.sourceforge.net/libdnet/libdnet-1.11.tar.gz?download" tar -zxvf libdnet-1.11.tar.gz cd libdnet-1.11 ./configure make && make install && ldconfig wget http://download.icu-project.org/files/icu4c/4.0.1/icu4c-4_0_1-src.tgz wget http://slackbuilds.org/slackbuilds/12.2/libraries/icu4c.tar.gz tar -zxvf icu4c-4_0_1-src.tgz tar -zxvf icu4c.tar.gz cd icu4c mv ../icu4c-4_0_1-src.tgz ./ ./icu4c.SlackBuild mv /tmp/icu4c-4.0.1-i486-1_SBo.tgz /root/ installpkg ./icu4c-4.0.1-i486-1_SBo.tgz wget http://mesh.dl.sourceforge.net/sourceforge/open-vm-tools/open-vm-tools-2009.02.18-148847.tar.gz tar -zxvf open-vm-tools-2009.02.18-148847.tar.gz cd open-vm-tools-2009.02.18-148847 ./configure --includedir=/usr/include/uriparser --without-x --without-icu make

Dalla VIM cliccare su Inventory-> Virtual Machine -> Install VMware Tools
tornare sulla console

mount /mnt/cdrom cp /mnt/cdrom/VMwareTools-3.5.0-123629.tar.gz /root/ tar -zxvf VMwareTools-3.5.0-123629.tar.gz cd open-vm-tools-2009.02.18-148847/modules/linux/ for i in *; do sudo mv ${i} ${i}-only; tar -cf ${i}.tar ${i}-only; done cp *.tar /root/vmware-tools-distrib/lib/modules/source/ cd /root/vmware-tools-distrib/ mkdir /etc/pam.d touch /etc/rc.d/init.d/network ifconfig eth0 down ifconfig eth1 down ifconfig eth2 down rmmod pcnet32 ./vmware-install.pl vmware-config-tools.pl

Ringrazio marcpem per l’how to originale

Error – mount nfs from linux client to windows server

admin — Tue, 24 Feb 2009 08:00:05 +0000

Ho avuto un problema con il mount di una share nfs windows server 2003 r2 da parte di un client linux.
Ottenevo sempre un problema di timeout o un errore di i/o.
Nei log c’era:
portmap: server localhost not responding, timed out

Il problema si risolve avviando il servizio portmap:

su redhat/centos:
/etc/init.d/portmap start

su slackware:
chmod ugo+x /etc/rc.d/rc.rpc /etc/rc.d/rc.rpc start

Slackware 12 su Asus Z99j o Aj8n – Gestione ACPI e tasti funzione

admin — Tue, 03 Jul 2007 22:08:00 +0000

Apena installata, la mia distro preferita (ovviamente Slackware 12) ACPI aveva qualche problama.
Sulla barra non compariva l’icona del controllo delle batterie e i tasti funzione non funzionavano
Ecco come ho risolto:

In fondo al file /etc/rc.d/rc.modules ho aggiunto le seguenti righe:
#######################################################
## ACPI MAOX X ASUS
/sbin/modprobe asus_acpi
/sbin/modprobe video
/sbin/modprobe battery
/sbin/modprobe container
/sbin/modprobe button
/sbin/modprobe ac
/sbin/modprobe thermal
/sbin/modprobe processor
/sbin/modprobe fan

/sbin/depmod -ae
###########################################################à
In queso modo è comparsa l’icona delle batterie e posso gestire il risparmio energetico.

Per i tasti funzione:
in /etc/acpi ho modificato il file acpi_handler.sh come segue:

###########################################################
root@trinity2:/etc/acpi# cat acpi_handler.sh
#!/bin/sh
# Default acpi script that takes an entry for all actions

IFS=${IFS}/
set $@

case “$1″ in

case “$2″ in

case “$2″ in

case “$3″ in
0000005e)
logger “WIFI in Accenione…”
/etc/acpi/wifi_on.sh
logger “WIFI Acceso!”
echo “WIFI Acceso!” | wall
;;
0000005f)
logger “WIFI in Spegnimento…”
/etc/acpi/wifi_off.sh
logger “WIFI Spento!”
echo “WIFI Spento!” | wall
;;
00000032)
logger “MUTE / UNMUTE AUDIO…”
MUTE=`amixer get PCM | grep Left | grep -v Right | cut -d ” ” -f 9`
if [ $MUTE == [on] ]; then
/usr/bin/amixer set PCM mute
else
/usr/bin/amixer set PCM unmute
fi
;;
00000031)
logger “Abbasso il volume…”
amixer set PCM 2-
;;
00000030)
logger “Alzo il volume…”
amixer set PCM 2+
;;

logger “BB $3 BB $4″
;;

###############################################################

Con questo file riesco a controllare il volume e l’attivazione della wireless dai tasti funzione su linux.
Premendo Fn+F10 attivo o disattivo l’audio
Premendo Fn+F11 abbasso l’audio
Premendo Fn+F12 alzo l’audio

e, sempre in /etc/acpi/ ho aggiunto i seguenti file:
#################WIFI_ON############################################
root@trinity2:/etc/acpi# cat wifi_on.sh
#!/bin/bash
/sbin/ifconfig eth0 down
/sbin/modprobe ipw3945
/sbin/depmod -ae
/sbin/ipw3945d –quiet
sleep 5
/sbin/dhcpcd -d -t 15 eth1
#################################################################

#######################WIFI_OFF###############################
root@trinity2:/etc/acpi# cat wifi_off.sh
#!/bin/bash
/sbin/ifconfig eth1 down

/sbin/ipw3945d –kill
/sbin/ipw3945d –kill
killall ipw3945d

/sbin/rmmod ipw3945
/sbin/depmod -ae

/etc/rc.d/rc.inet1 restart
###############################################################

poi un bel
chmod ugo+x /etc/acpi/wifi_*

In questo modo posso attivare e disabilitare la wireless tramite la combinazione di tasti
Fn+F2
