$ wget ftp://ftp.rsa.com/pub/agents/j2me/JME23.zip
$ wget ftp://ftp.rsasecurity.com/pub/agents/TokenConverter.tar.gz
$ mkdir securId

$ unzip JME23.zip -d securId/
$ tar -C securId -zxvf TokenConverter.tar.gz
$ cd securId
# Convert your RSA token into required format
$ cp some_directory/token_file.sdtid .
$ chmod +x TokenConverter
$ ./TokenConverter token_file.sdtid -p 'password_you_got_from_admin' -o num_out
$ cat num_out | rev | sed -e :a -e 's/\(.*[0-9]\)\([0-9]\{5\}\)/\1-\2/;ta' | rev

# Edit SecurId.jad and add the following lines
X-NumericInput: 21111-12593-96653-61657-73256-55655-33735-53711-52131-25113-57215-55172-12151-26371-12716-73632-5
X-AllowNumericInput: No
$ java -cp /opt/microemulator/microemulator.jar:SecurID.jar org.microemu.app.Main com.rsa.swtoken.j2me.client.SecurID

Enter your PIN and you should get a 8-digit passcode which can be used with vpnc

vpnc can be setup the same as done for desktop linux as in

Mplayer shortcuts on nokia N900

Nokia N900 has limited of keys in its keyboard. Some of the special characters like '[' and ']' are missing from the keyboard. While using mplayer '[' and ']' are used to increase/decrease the speed of the video.

As these keys are missing from the keyboard, you can re-map increase/decrease speed functionality to other keys by having a custom input.conf file. A sample input.conf to re-map increase/decrease speed to '(' and ')'

( speed_mult 0.9091    # scale playback speed
) speed_mult 1.1
