Substitute for Putty SSH client on Nokia 9300i

Sunday, May 30th, 2010

Reading Time: 2minutes
I’ve recently had issues with my Putty for S80 on my Nokia 9300i.
Though the port of Putty for Symbian is quite good looking it has many down falls. A major down side is it’s slowness, a connectionto an SSH server would take up like 5 to 7 minutes time.
As they say time and money and loosing time is annoyance and this is especially true if you have to quickly do something on a server via your mobile.

I looked online for good SSH clients that might be a substitute to the PuTTY SSH client In my search I came across this list of SSH clients compatible with the Symbian’s S80 phone architecture

Mocha Telnet client for Nokia 9300, 9300i and Nokia 9500

I haven’t tested all of the provided clients but I was blessed to find what I was looking for, I found the Mocha Telnet for Nokia 9300/9500 which is a really nice SSH and Telnet client. I had to acknowledge, it’s interface and it’s SSH session management interface is a way down uhandy but in general the Mocha Telnet is a quickly connection handler able to communicate with the remote SSH servers on Nokia 9300i.
Usually to establish an SSH connection to a server it tooks like 1 minute using the Mocha Telnet this is really quick compared to the 6 minutes waiting while using PuTTY.

Here is a list of the capabilities of the Mocha Telnet client for Nokia 9300 / 9500 (a quote from Mocha telnet’s website):

Mocha Telnet Features:

* VT220 emulation.
* SSH2
* Autologin with scripting parameter.
* User defined function keys.
* Screen mode 24*80.
* Online Help.
* Many trim parameters.
* Small and fast.
* Free upgrades to new versions of the product.

To download the Mocha Telnet SSH for your Nokia 9300i check here

The Mocha Telnet creators Mocha Sof provides also a nice vnc client for Nokia 9300i you can download the program from here

But wait there is even some more glad glad tidings about Mocha Telnet and the Vnc. It seems since the programs product cycle is over and there are no new versions of the programs developed for the Nokia 9300i and a few other old school Symbian powered Nokia phones, MochaSoft decided to liberate the applications as a freeware by providing a freeware registration codes for the programs to benefit from the codes and register both your Mocha Telnet you can use:

Freeware license key for mocha Telnet for Nokia 9300,9300i/9500:

License name: freeware
License key: A15761

The Freeware license key for mocha VNC for Nokia 9300,9300i/9500 is:

License name: freeware
License key: 142449

In case if you’re curious, how administration of a remote Windows server will look alike over a VNC client, here is also a nice screenshot of Mocha VNC for the Nokia 9300i mobile:

How to increase brightness on Fujitsu Siemens Amilo PI22515 notebook with Slackware Linux

Increase LCD screen brightness on Fujitsu Siemens Amilo laptop with Linux Slackware

A friend of mine has Fujitsu Siemens Amilo laptop and is full time using his computer with Slackware Linux.

He is quite happy with Slackware Linux 13.37 on the laptop, but unfortunately sometimes his screen brightness lowers. One example when the screen gets darkened is when he switch the computer on without being plugged in the electricity grid. This lowered brightness makes the screen un-user friendly and is quite tiring for the eye …

By default the laptop has the usual function keys and in theory pressing Function (fn) + F8 / F7 – should increase / decrease the brightness with no problems, however on Slackware Linux (and probably on other Linuxes too?), the function keys are not properly recognized and not responding whilst pressed.
I used to have brigtness issues on my Lenovo notebook too and remember how irritating this was.
After a bit of recalling memories on how I solved this brightness issues I remembered the screen brigthness on Linux is tunable through /proc virtual (memory) filesystem.

The laptop (Amilo) Fujitsu Siemens video card is:

lspci |grep -i vga
00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) (rev 03)

I took a quick look in /proc and found few files called brightness:
 

  • /proc/acpi/video/GFX0/DD01/brightness
  • /proc/acpi/video/GFX0/DD02/brightness
  • /proc/acpi/video/GFX0/DD03/brightness
  • /proc/acpi/video/GFX0/DD04/brightness
  • /proc/acpi/video/GFX0/DD05/brightness

cat-ting /proc/acpi/video/GFX0/DD01/brightness, /proc/acpi/video/GFX0/DD03/brightness, /proc/acpi/video/GFX0/DD04/brightness all shows not supported and therefore, they cannot be used to modify brightness:

bash-4.1# for i in $(/proc/acpi/video/GFX0/DD0{1,3,4,5}/brightness); do \
cat $i;
done
<not supported>
<not supported>
<not supported>
<not supported>

After a bit of testing I finally succeeded in increasing the brightness.
Increasing the brightness on the notebook Intel GM965 video card model is done, through file:

/proc/acpi/video/GFX0/DD02/brightness

To see all the brightness levels the Fujitsu LCD display supports:

bash-4.1# cat /proc/acpi/video/GFX0/DD02/brightness
levels: 13 25 38 50 63 75 88 100
current: 25

As you can see the dark screen was caused cause the current: brightness is set to a low value of 25.
To light up the LCD screen and make the screen display fine again, I increased the brightness to the maximum level 100, e.g.:

bash-4.1# echo '100' > /proc/acpi/video/GFX0/DD02/brigthness

Just for the fun, I've written also a two lines script which gradually increases LCDs brightness 🙂

bash-4.1# echo '13' > /proc/acpi/video/GFX0/DD02/brightness;
bash-4.1# for i in \
$(cat /proc/acpi/video/GFX0/DD02/brightness|grep 'levels'|sed -e 's#levels:##g'); do \
echo $i > /proc/acpi/video/GFX0/DD02/brightness; sleep 1; \done

fujitsu_siemens_brightness_fun.sh script is fun to observe in changing the LCD screen gradually in one second intervals 🙂

Here is also a tiny program that reduces and increases the notebook laptop brightness written in C. My friend Dido, coded it in just few minutes just for the fun 🙂
To permanently solve the issues with darkened screen on boot time it is a good idea to include echo '100' > /proc/acpi/video/GFX0/DD02/brigthness in /etc/rc.local:

bash-4.1# echo '100' > /proc/acpi/video/GFX0/DD02/brigthness

I've also written another Universal Linux Increase laptop screen brightness Shell script which should be presumable also working for all Laptop models running Linux 🙂

My maximize_all_linux_laptops_brightness.sh "universal increase Linux brightness" script is here
I'll be glad to hear from people who had tested the script on other laptops and can confirm it works fine for them.
