wrt54g v 2.0 howto

1.
get this:
http://open-wrt.ru/downloads/kamikaze/8.09.2/brcm-2.4/openwrt-wr850g-squashfs.bin

on some linux do:
dd if=firmware.bin of=firmware.trx bs=32 skip=1

wget firmware.trx on /tmp of wrt54g

http://nuwiki.openwrt.org/oldwiki/OpenWrtDocs/Deinstalling

mtd -e linux -r write firmware.trx linux

and

reboot

http://wiki.openwrt.org/doc/uci/wireless/encryption

root@OpenWrt:~# uci set wireless.@wifi-iface[0].encryption=psk2
root@OpenWrt:~# uci set wireless.@wifi-iface[0].key="your_password"
root@OpenWrt:~# uci commit wireless
root@OpenWrt:~# wifi

Configuration is also possible via direct editing of /etc/config/wireless

at end:
uci commit wireless

uci set wireless.@wifi-device[0].disabled=0 - can be other variable SEARCH disabled
uci show | grep disabled

and start it with

wifi


set new password for root with
password - this activate sshd after reboot and disable telnet

reenable dnsmasq and httpd and any in this dir /etc/rc.d/
with
/etc/rc.d/name enable
It may seems that some of them are started but it's not so enable one by one.
Because wireless work devices are connected but can't get IP.

add your rules in
/etc/rc.local

opkg update
opkg upgrade
opkg list - for packages
opkg install name of package

You may need more of iptables pakages for TTL or some filtering or shaping !
They are named with "extra" at end

Add a firewall rule

This is a good example of both adding a firewall rule to forward the TCP SSH port, and of the negative (-1) syntax used with uci.

uci add firewall rule uci set firewall.@rule[-1].src=wan


uci set firewall.@rule[-1].target=ACCEPT


uci set firewall.@rule[-1].proto=tcp


uci set firewall.@rule[-1].dest_port=22


uci commit firewall

change the wan MAC address.

/etc/config/network you can run the commands below to change the wan
MAC address.
uci set network.wan.macaddr=""
uci commit network
ifdown wan && ifup wan

2.6.33 and 2.6.34 kernel suspend hibernate trouble

For 2.6.33: USB3 module is: xhci
For 2.6.34: USB3 module is: xhci_hcd

Before start suspend:

rmmod xhci_hcd ehci_hcd ohci_hcd forcedeth hangcheck-timer usbcore

After resume must:

modprobe usbcore
modprobe xhci_hcd
modprobe ehci_hcd
modprobe ohci_hcd
modprobe forcedeth
modprobe hangcheck-timer


Usually script's know for all this but not for USB3. And you will see this error:
/usr/lib64/pm-utils/pm-functions: line 295: echo: write error: Input/output error
or
/usr/lib64/pm-utils/pm-functions: line 295: echo: write error: No such file or directory

or similar. This is not a bug. This is caused from:

kernel: hub 6-0:1.0: cannot reset port 1 (err = -19)
kernel: hub 6-0:1.0: cannot disable port 1 (err = -19)

PM: Device usb2 failed to freeze async: error -2
kernel: PM: Device usb2 failed to suspend async: error -2
kernel: PM: Some devices failed to suspend

It can be seen in Slackware log's after : pm-suspend
this command produce very helpful LOG.

gpsd test install log - tangogps

gpsd - get and install from berlios:

tangoGPS - from home page

start like root:
gpsd -N -G -D 4 /dev/ttyUSB0

GPS device - /dev/ttyUSB0 - for My
-N to get data continuously
-G to listen on all interfaces
-D debug Level

To test:
telnet 0.0.0.0 2947

To get log from GPSD:
cgpxlogger > track.gpx
- for quick test cgps is used.
- do not use tee or other - will broke XML at END.

If all working well and GPS get signal:
- see in telnet:

This mean that GPS Lock position from Two satelites! This is very important.

If not Lock acquired, you will see:
"GPS has no fix" in gpsd log
and
A,1 - in telnet log
and no gpx log will be created from cgpslogger.
Any program will not work and give strange results :).

catalist 10.5

From Aur: patches for 2.6.33 and 2.6.34-rc4.

--extract SomeDir

cd SomeDir/common/lib/modules/fglrx/build_mod/
cat PatchName| patch

cd SomeDir

memtest86+ on 64 Amd

memtest86+-4.10 HowTo

make
memtest.bin - linux Kernel x86 :)
copy "memtest.bin" to your boot dir /boot usually, not memtest it's ELF exe
edit
/etc/lilo.conf
add this:

image = /boot/memtest.bin
root=/dev/sda3 # no need
label = Memtest86

execute from bash like root, to refresh Loader >lilo

Grub: close to upper.

reboot choose memtest! And Happy waiting.

Sata hot add remove

Hot Add: redetect for devices on Bus 0, replace host0 with host0-.. for other. It's harmless to try with all ready working devices.
echo "- - -" > /sys/class/scsi_host/host0/scan

Hot Remove: spin down and disable device. Be careful - it can be Root, or mounted device.
!!! Some SATA devices are not HOT swap. !!!
echo 1 > /sys/block/sda/device/delete

slackware 64 with 32bit support compile trouble

1. Pass LDFLAGS to configure, possibly
LDFLAGS='-L/lib64 -L/usr/lib64 -L/usr/X11/lib64 -L/opt/kde/lib64' or
something like that.

This help mi, compiling libtorrent: LDFLAGS='-L/lib64 -L/usr/lib64' ./configure
