FreBSD ports, switch from fetch to wget

2009-07-29T04:32:00.005+07:00

The FreeBSD ports system uses fetch to download the files from the distfiles
i stand behind "i-can't-guess" firewall and proxy
many fetch options don't give me solutions
someday i try wget, and it works perfectly
and i want to switch ports system from "fetch" to "wget"

First

install wget
( by ports, by package, or anything you can install )

Second

[root@ ~]# cd /usr/ports/Mk
[root@ /usr/ports/Mk]# vi bsd.port.mk

edit to

.if exists(/usr/bin/fetch)
#FETCH_BINARY?= /usr/bin/fetch
#FETCH_ARGS?= -ApRr
#FETCH_REGET?= 1
.if !defined(DISABLE_SIZE)
#FETCH_BEFORE_ARGS+= $${CKSIZE:+-S $$CKSIZE}
.endif
.else
FETCH_BINARY?= /usr/bin/ftp
FETCH_ARGS?= -R
FETCH_REGET?= 0
.endif
FETCH_CMD?= /usr/local/bin/wget
#FETCH_CMD?= ${FETCH_BINARY} ${FETCH_ARGS}

wget configuration

/usr/local/etc/wgetrc

FreeBSD mount iso image

2009-06-29T08:10:00.002+07:00

Mount iso image to your local hardrive

[root@ ~/bsd/FreeBSD7]# ls *.iso
7.0-RELEASE-i386-disc1.iso
[root@ ~/bsd/FreeBSD7]# mdconfig -a -t vnode -f 7.0-RELEASE-i386-disc1.iso
md0
[root@ ~/bsd/FreeBSD7]# mkdir satu
[root@ ~/bsd/FreeBSD7]# mount -t cd9660 /dev/md0 satu/

to unmount, simply

[root@ ~/bsd/FreeBSD7]# umount satu
[root@ ~/bsd/FreeBSD7]# mdconfig -d -u /dev/md0

Mount FTP to local directory

2009-05-10T21:58:00.006+07:00

OpenBSD disable usb and isa port

2008-12-04T16:54:00.000+07:00

just curious why superkayak can't boot default OpenBSD /bsd kernel
always stuck at hardware detection
it's also happen with installation kernel

and then know the culprit
i have to disable usb and isa port first before boot
by using "boot -c" at boot time and disabling them
after you can login to your box
lets edit the kernel (to disable usb and isa port )

# config -e -o /bsd.sip /bsd
OpenBSD 4.4 (GENERIC) #1021: Tue Aug 12 17:16:55 MDT 2008
deraadt@i386.openbsd.org:/usr/src/sys/arch/i386/compile/GENERIC
Enter 'help' for information
ukc> disable usb
348 usb* disabled
ukc> disable isapnp
314 isapnp0 disabled
ukc> quit
Saving modified kernel.

# mv bsd bsd.old
# mv bsd.sip bsd
# reboot

Linux Tv Tuner card

2008-12-04T11:15:00.000+07:00

Just note
nak ono sing tekak tekok kari ngelink mrene

TV tuner info

niyala ~ # lspci -v
01:08.0 Multimedia controller: Philips Semiconductors SAA7130 Video Broadcast Decoder (rev 01)
Subsystem: Animation Technologies Inc. LifeView FlyVIDEO2000
Flags: bus master, medium devsel, latency 32, IRQ 20
Memory at e3001000 (32-bit, non-prefetchable) [size=1K]
Capabilities: [40] Power Management version 1

make sure, line out from tv tuner plugged into soundcard line input
make sure, you have compiled the driver modules
make sure, you know your card and tuner options

i'am a gentoo user, i use udev to manage the hardware
udev also support for coldplugging ( hardware detection at boot )
from this i have a problem,
because i don't know how to insert module option to load tv tuner module into the kernel
finally i use blacklist from udev,
first do not load automatically ( using udev coldplug ) by blacklisting the module
and then use modules autoload to load the modules

niyala ~ # echo "blacklist saa7134" >> /etc/modprobe.d/blacklist
niyala ~ # echo "options saa7134 card=3 tuner=25" > /etc/modules.d/saa7134
niyala ~ # echo "saa7134" > /etc/modules.autoload.d/kernel-2.6
niyala ~ # echo "tuner" > /etc/modules.autoload.d/kernel-2.6

when your computer reboot, the driver module ready to go ...

i use xawtv for tv viewer and qqradio for radio tuner

View only configuration lines ( uncomment lines )

2008-08-31T13:35:00.001+07:00

Linux configuration files using comment and uncomment lines ( # )
and sometimes we don't need the comment lines, we only need the uncomment lines ( usable configuration files )

here is the script to view only configuration lines / uncommment lines
example squid.conf

Using ssh with Konqueror

2008-08-02T10:44:00.001+07:00

You can using ssh acces using konqueror,
drag, drop, right left click

this combination make easier working with a remote machine

Simple wget list download

2008-06-08T14:34:00.001+07:00

Using wget to download your list

arz@niyala ~/work $ cat don.txt
http://www.abc.com/images/1.jpg
http://www.abc.com/images/2.jpg
arz@niyala ~/work $ for i in `cat don.txt`; do wget $i ; done

any idea to download using wilcard on wget ?
for non ftp and non directory listing websites
it seem impossible, but maybe some tricky ones ?
