iSlackware : My Slackware Journey, Tips and Tricks

Adhoc wireless AP for idevice under slackware /Linux

noreply@blogger.com (keith GWK) — Mon, 26 Sep 2011 18:53:00 +0000

During my recent business trip i encountered a problem connecting the internet with my idevice in hotel room. As in the hotel room they only provide wired Internet connection. The wireless hotspot is only available in the hotel lobby.

Of course, a wired Internet for idevice? It is impossible for now as the idevice has no network port.

It was too bad that I didn't bring along my TPLink USB adaptor. So how to go along with it?

...Via adhoc network... of course!

The idevice's apps work as there are connected to a wireless LAN. viber, skype, ppstv, whatsapp etc. FaceTime not quite working here- bad quality.

Please find the simple workaround to achieve this for slackware/linux as below:

====
# connect to the wired network
dhcpcd -R eth0
# setting up the wireless adaptor
iwconfig wlan0 mode ad-hoc
ifconfig wlan0 192.168.1.1 netmask 255.255.255.0
iwconfig wlan0 channel auto
iwconfig wlan0 essid urssid

# turn on ip forwarding and masquerading.
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -s 192.168.1.0/24 -o eth0 -j MASQUERADE
====
You can setup a dhcp server if you want to.

If you don't just setup an IP for your idevice. I.E 192.168.1.2 etc.

PPStream on Slackware : firefox and Flash player

noreply@blogger.com (keith GWK) — Sat, 17 Sep 2011 08:50:00 +0000

The picture below shows that The PPStream for Linux especially Slackware will not work if you have the flashplayer plugin in your firefox profile directory.

All you can do is just rename the plugins directory or remove the flashplayer plugin. This means your firefox will still be able to run as usual(without flash plugins).

Compaq nc6230+Slackware+Hostapd+TL-WN722N+Ath9k_htc+iptables+dhcpd : How to put them together

noreply@blogger.com (keith GWK) — Sat, 23 Jul 2011 13:12:00 +0000

After few weeks of searching thru the internet; testing and retest and... etc.

Finally, have found the way to put them together.

The below combination is do-able:
Laptop Compaq nc6230
Slackware version = slackware 13.1
Kernel = linux-3.0.0-rc7
hostapd = hostapd-0.7.3
TL-WN722N = using ath9k_htc (direct from the kernel)
iptables = original from slackware 13.1
dhcpd = from slackware 13.1

Connecting with iPhone4 and iPad2 IOS 4.3.3 have no problem...

IPHONE OpenSSH - ssh_exchange_identification: Connection closed by remote host

noreply@blogger.com (keith GWK) — Fri, 20 Aug 2010 04:47:00 +0000

This is a bit out of topic...

When you are not be able to ssh to your iphone... as the error message as below:
ssh_exchange_identification: Connection closed by remote host

it's very high possibility that you have inflected by the ikey virus.

you can do as below:

1. reinstall openssh; then do /usr/bin/ssh root@your_iphone_ip "rm /bin/poc-bbot /bin/sshpass /var/log/youcanbeclosertogod.jpg /var/mobile/LockBackground.jpg /System/Library/LaunchDaemons/com.ikey.bbot.plist /var/lock/bbot.lock /usr/libexec/cydia/startup /usr/libexec/cydia/startup.so /usr/libexec/cydia/startup-helper /System/Library/LaunchDaemons/com.saurik.Cydia.Startup.plist"

or

reinstall openssh; then use your ssh client login and cut and paste "rm /bin/poc-bbot /bin/sshpass /var/log/youcanbeclosertogod.jpg /var/mobile/LockBackground.jpg /System/Library/LaunchDaemons/com.ikey.bbot.plist /var/lock/bbot.lock /usr/libexec/cydia/startup /usr/libexec/cydia/startup.so /usr/libexec/cydia/startup-helper /System/Library/LaunchDaemons/com.saurik.Cydia.Startup.plist" (need to do it quick before the server's off; redo step 1 if you missed it.)

2. reinstall the openssh again; then change your openssh password.

if the above steps don't work.

reinstall cydia and then openssh; then change your openssh password.

See? the point is 'change your openssh password'!!!

Financial application - gnucash on slackware

noreply@blogger.com (keith GWK) — Sun, 19 Jul 2009 07:44:00 +0000

Yes. It's really challenging to install the gnucash under slackware. For this financial application to work under slackware, the fastest and direct method will be install the dropline gnome. Have no idea what to install? Just download and install the full package of dropline.

It's been five years i used gnucash to manage my finance. I found it very useful especially use it together with my nokia application, jabplite. I use jabplite for keep tracking the expenses daily and then update gnucash entries weekly.

So what you would do - go gooogle then, install dropline, gnucah and get a nokia series60 phone. :)

Slackware and Photography #4 : exiftool

noreply@blogger.com (keith GWK) — Mon, 20 Apr 2009 15:31:00 +0000

For viewing and editing the exif data for the images, i use exiftool. This tool is so powerful that you can create and manipulate the exif data contains in an image.

Viewing the info....

Editing and Copying... the thing i love to do is, i create a very lousy script to make exiftool to delete all the exif info and copy the info that i want to exif:usercomment.For more information please check the man page.

Nothing fancy... just utilize what's good for me.. of course, the credit goes to the author.. well done.. thank you. :)

if you have any questions, dont hesitate to comment.. ;)

Slackware and Photography #1 : Slackware and KphotoAlbum

noreply@blogger.com (keith GWK) — Mon, 06 Apr 2009 14:29:00 +0000

When i started to learn photo shooting, i was once stuck in the middle where i have some problem to manage my photos under slackware.

How am i gonna manage such a big amount photos? My shutter count reached 8k+ in about 3 months. I dumped all the image files into my harddisk and because they were so messy and i have no choice to delete about 2k+ of them which initially i preferred to keep them all since those are part of my learning process...

How am i gonna do batch rename? Using a customized script? But well, which are under which category? Due to all these issues, i started to source/'google' to find a suitable application running under linux for these purposes.

Finally, I've found KPhotoAlbum which's nice and meet my requirements. Installing it under slackware 12.x considers very simply. :)

Below are the functions which i used most...

Main window...

Maintenance pop-up...

Plugin pop-up...

Export functions...

Batch processing functions...

The summary of the features...

About My Slackware Journey

noreply@blogger.com (keith GWK) — Wed, 25 Mar 2009 07:25:00 +0000

While having a tight budget on buying a windows OS for my computers, I got an advice from my unix lecture, Mr Lynch,who recommended me to give linux OS a try back in 1998 Spring. I was then failing in love on how wonderful this OS is and until now, at home I use slackware, slackware, slackware and slackware. The amazing slackware linux is the one I love since day one.

Why slackware? Slackware was not so user-friendly at the beginning. What I mean is the first slackware 3.1.0 installed in my computer in 1998. And that’s what exactly I love about it. Without the user-friendly interface, you will learn more from it and aware of what’s really happening.

This blog will cover about slackware, my slackware linux journey. Most of the topic that I’ll cover here will be the 3rd party applications running under slackware which I use daily.

Do feel free to comment and don’t hesitate to try my skills under slackware. If I cant answer your question, I will google... (hahaha) and then integrate/consolidate the information and blog about it … :)

Happy slackwaring… :)
