Some configuration stuffs for HP 540
Set timezone to NST
| File: /etc/conf.d/clock |
CLOCK="local" TIMEZONE="Asia/Kathmandu" |
Set hostname
| File: /etc/conf.d/hostname |
HOSTNAME="my-laptop" |
Configure syslog-ng
| File: /etc/syslog-ng/syslog-ng.conf |
# add these lines
options { create_dirs(yes); perm(0660); dir_perm(0770); };
destination per_daemon { file("/var/log/syslog-ng/daemon/${PROGRAM}.log"); };
log { source(src); destination(per_daemon); };
# this creates log structures as follows
# /var/log/syslog-ng/daemon/acpid.log
# /var/log/syslog-ng/daemon/cron.log
# /var/log/syslog-ng/daemon/dhcpcd.log
# /var/log/syslog-ng/daemon/gdm.log
# /var/log/syslog-ng/daemon/gdmsetup.log
# /var/log/syslog-ng/daemon/gnome-power-manager.log
# /var/log/syslog-ng/daemon/groupadd.log
# /var/log/syslog-ng/daemon/init.log
# /var/log/syslog-ng/daemon/kernel.log
# /var/log/syslog-ng/daemon/logger.log

Configure logrotate.d to include above syslog files
| File: /etc/logrotate.d/syslog-ng |
# edit or add these lines to logrotate above mentioned syslog files
/var/log/messages <b>/var/log/syslog-ng/daemon/*.log</b> {
missingok
sharedscripts
postrotate
/etc/init.d/syslog-ng reload > /dev/null 2>&1 || true
endscript
}
|
I see lots of unnecessary log files with my name in /var/log/syslog-ng/daemon, so I've made a bash script to clean them manually
| File: /var/log/syslog-ng/1_cleanup.sh |
#!/bin/sh # 07-sep-2009 - keshav.maharjan@worldlink.com.np find /var/log/syslog-ng/daemon/*keshav* | xargs rm rm /var/log/syslog-ng/daemon/.log |
Set displaymanager to gdm instead of default xdm
| File: /etc/conf.d/xdm |
##DISPLAYMANAGER="xdm" DISPLAYMANAGER="gdm" |
Configuration for wireless network connection
| File: /etc/conf.d/net |
# Wlink ?
key_Wlink="xxxxxxxx enc open"
...
mac_essid_000102030405="myssid"
key_myssid="enc off"
preferred_aps=( "Wlink" "myssid" )
config_eth0=( "dhcp" )
config_wlan0=( "dhcp" )
preup() {
# for eth0
#if mii-tool "${IFACE}" 2> /dev/null | grep -q "transceiver"; then
if ethtool "${IFACE}" | grep -q 'Link detected: no'; then
ewarn "No link on ${IFACE}, aborting configuration"
return 1
fi
# for wlan0
if ethtool "${IFACE}" | grep -q 'No data available'; then
return 0
fi
# for eth0
ewarn "Link ON on ${IFACE}"
return 0
}
postup () {
# for wlan0
if [[ ${IFACE} == "wlan0" ]]; then
iwconfig wlan0 txpower on
fi
}
|
Configure to name wireless interface wlan0 instead of generic eth1
| File: /etc/udev/rules.d/70-persistent-net.rules |
...was... KERNEL=="eth*", NAME="eth1"
...changed to ... KERNEL=="eth*", NAME="wlan0"
# PCI device 0x14e4:0x4315 (wl)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:01:02:03:04:05", ATTR{type}=="1", KERNEL=="eth*", NAME="wlan0"

How to automatically set brightness according to the time of day
Create file /etc/cron.hourly/set_brightness.sh
and chmod it 755.
| File: /etc/cron.hourly/set_brightness.sh |
#!/bin/sh
# 2009-09-09 - keshav.maharjan@worldlink.com.np
hour=`date +%H`

# levels: 30 37 44 51 58 65 72 79 86 93 100
# current: 44
case "$hour" in
08 | 09 | 10 )
