Enigma2 tuner Telnet: common Unix/Linux Commands used via Telnet.

Version 1.10

For detailed explanations of UNIX (Linux) commands see:
List of Unix utilities on Wikipedia
Note: The tuner runs a small subset of these commands, and some commands are quite limited in their support for extra options. But they aren't dramatically different.

Start a telnet session

Use a telnet client configure Enigma2 tuner ip address in settings.
See: A detailed description on how to configure PuTTY, as added bonus, this allows you to securely access your box from anywhere in the world.

Login as user root, hit enter button, and type the password if prompted (default=dreambox on a Dreambox tuner)


See all compatible commands.
Login with telnet client, when telnet client is logged in, press Tab Tab (so 2x TAB button)

Type smarter not faster
The TAB key will also "auto-complete" commands and options for you. So instead of a full file name, you can usually just type a part of the name and press TAB. Pressing TAB again will display a list of possible matches.

Change Enigma2 tuner root password.
passwd

Minimal 5 and maximal 8 characters long, and can consist of UPPERCASE/lowercase letters and numbers.


Solving a jammed Enigma2 tuner.
killall enigma2



Reboot a Enigma2 tuner.
reboot



Change powerstate of a Enigma2 tuner.
Note: Change password in your used root password!
Standby:
wget -O /dev/null -q http://root:password@localhost/web/powerstate?newstate=0

DeepStandby:
wget -O /dev/null -q http://root:password@localhost/web/powerstate?newstate=1

Reboot:
wget -O /dev/null -q http://root:password@localhost/web/powerstate?newstate=2

Restart Enigma2:
wget -O /dev/null -q http://root:password@localhost/web/powerstate?newstate=3

Wakeup from Standby:
wget -O /dev/null -q http://root:password@localhost/web/remotecontrol?command=116



Basic navigation.
cd (”change directory”), will take you back to your $HOME directory
cd

To change to a specific directory, type cd followed by the path to the directory. If it is a subdirectory of the current directory, you can just type the directory name.
cd /path/to/directory

Typing cd .. moves you up one directory from your current location.
cd ..

To see which directory you are in, type pwd (”print (display) working directory”).
pwd

Just as it sounds, use exit to log out.
exit



Creating and deleting directories.
To create a new directory, type mkdir (”make directory”) and specify the new directory’s name.
mkdir directoryname

To delete an empty directory, type rmdir (”remove directory”) and the directory’s name.
rmdir directoryname



Install & remove & list packages.
To get a package to /tmp directory on Enigma2 tuner and unzip it:
cd /tmp
wget exact-package-name.ipk.zip
unzip exact-package-name.ipk.zip

Installation:
ipkg install exact-package-name.ipk

or
ipkg packagename

Uninstall:
ipkg remove exact-package-name.ipk

List installed packages:
ipkg list_installed

List all packages:
ipkg list

List only enigma2 plugin packages:
ipkg list "enigma2-plugin*"

To filter the list, added the filtered word after the command between two stars, example: ipkg list_installed *plugin*


Update Open-Pli Enigma2 tuner.
init 4
ipkg update && ipkg upgrade
init 3
exit



Create Enigma log (see what Enigma does).
init 4
enigma2

or
init 4
/bin/sh /usr/bin/enigma2.sh

Telnet will output Enigma2 activity. To stop press CTRL-C.
To resume normal operation:
init 3



Create Enigma screenshot.
grab /tmp/screenshot.bmp

After that go with ftp client or network browser to /tmp/ directory of Enigma2 tuner/pvr and download the screenshot.bmp file. Type "grab" to see more options, for saving jpg/png files and mixing video and OSD.


Listing files.
To display a list of files and subdirectories in your current directory, type ls (”list”)
ls

To see a more complete list which includes hidden files or files that begin with a “.” (dot), type ls -a.
ls -a

To list all files and directories in long format which will provide details about each file and directory, type ls -la.
ls -la

To list all directories and files, sorted by size, in long format, type ls -lS.
ls -lS

To list all files and directories in long format by time modified, type ls -lta.
ls -lta



Copying files.
Copy the contents of one file to another file, resulting in two copies of the same file on your account.
cp oldfilename newfilename

Copy the contents of one directory to another directory. Make sure you have created the destination directory before trying to copy files to it - see mkdir above. Results in two copies of the files on your account; one copy in the existing directory and another in the destination directory.
cp directory/* destinationdirectory

Copy a whole directory tree, including subdirectories:
cp -r /etc/enigma2 /hdd/backup/

This will create /hdd/backup/enigma2, and copy everything in it.


Searching files and directories.
The find command can be used to locate files or a group of files. It can also be used to display directories. The example given will find all file and directory names within the current directory and subdirectories of it that begin with the letter n. (You can also explore using the locate command - type info locate and/or man locate for usage information.)
find -name ‘n*’

To locate text in a specific file or directory of files (use * in place of filename to search all of the files in the current directory). The -i argument indicates the search is to disregard cASe, the -n instructs to show the corresponding line number, and -w tells it to match only based on the whole word. (This doesn’t even begin to touch on the power of grep and its many uses. In addition to its searching capability, the grep command can be used in combination with other commands to act as a filter. It also allows the use of “wildcards”. Two other variations of grep are also available, egrep and fgrep. To begin your quest for more information, type man grep and/or info grep.)
grep -inw text filename



Displaying / comparing file content.
Counts and displays the number of lines, number of words, and number of characters of the given file.
wc filename

Displays the entire contents of a file.
cat filename

Shows the content of the file, including line numbers (nl=number lines).
nl filename

Displays the contents of a file one screen at a time. Press the SPACEBAR to display the next screen of text.
more filename

Compares the contents of the two named files and reports the first different character found and the line number.
cmp filename1 filename2

Compares the contents of the two named files and reports all of the differences found. (Can also be used for comparing the contents of two directories.)
diff filename1 filename2



Moving, renaming, and deleting files.
Use to rename a file (mv fileA fileB), move a file (mv fileA /dirA/), or both (mv fileA /dirB/fileB).
mv oldfilename newfilename

Removes (deletes) the specified file. (The -i is not necessary, but is recommended as it will prompt you to confirm the action first. When prompted, type y to confirm or type n if you changed your mind.)
rm -i filename



Changing permissions.
Changes the permissions on a filename or directory as specified. (First go with cd command to directory where the file is.)
chmod permissions filename

This permission is only nessesary if a script (*.sh) or specific type of file won't work/handle properly. Normally you don't need to give permission to new files. And don't use too much permissions because that can be unsafe. For example 777 is pure evil. More chmod info can be found in this link. Here a example of a chmod for a script file,
chmod 755 HackSat_Key_downloader_userscript.sh

You can also add or remove permissions using letters (you can see them with "ls -l", as described above), which is handy for multiple files, to strip away "execute" permission from all files, or to add "read" and "execute" to all .sh files, or make all files read-only (not writable):
chmod a-x *
chmod a+rx *.sh
chmod a-w *



Archives and compression.
To archive a directory and all of its contents including subdirectories, navigate to where the directory is located and type the above command, replacing filename.tar with the name you wish to give the archive file and directoryname with the name of the directory you wish to archive. Alternatively, you can archive a select group of individual files (or directories) by specifying each file name in place of directoryname separated by spaces, like tar -cvf filename.tar fileA fileB fileC. Note: When creating a tar file (aka “tarball”) be sure to specify the name you wish to give the tar file! (TAR indicates Tape ARchive, as it was originally a tape archiving program. The -c means “create”, v means “verbose” (which basically says tell me what you’re doing), and the f indicates that a filename will follow (filename.tar)).
To create, list or extract from gzip compressed archives, use the extra "z" switch. Note that "-czf" if identical to "-c -z -f". Most archives were created this way.
tar -cvf filename.tar directoryname
tar -czvf filename.tar.gz directoryname

Typing this command will result in a list of the contents of the tar file. This is generally a good thing to do before unpacking the tar file to be sure there are no matching filenames which will result in files being unintentionally overwritten.
tar -tvf filename.tar
tar -tvzf filename.tar.gz

You can see the similarities to the command used to tar the file. This time, though, you use -x to “extract” instead of the -c used to create. The files will be placed in the current directory. You can also extract only certain select files (or directories) by specifying the individual names, separated by spaces, after the tar filename, such as tar -xvf filename.tar fileA fileC
tar -xvf filename.tar
tar -xzvf filename.tar.gz

Instead of the -z switch, you can use gzip on the commandline to compress single files. This is much less efficient though. The filename will automatically change from filename.tar to filename.tar.gz (appending .gz to the file extension).
gzip filename.tar

This command (g”unzip”) is used to uncompress a .gz file, which will also result in the filename being changed back to filename.tar. Alternatively, you can use gzip -d (for “decompress”) in place of gunzip.
gunzip filename.tar.gz

Sometimes ".tar.gz" is abbreviated to ".tgz".
You may also encounter "bzip2" files, typically named filename.tar.bz2. To uncompress these, type the following:
bunzip filename.tar.bz2 | tar xvf -

(notice the vertical bar and the dash at the end)


To reboot and stop the Enigma2 (Dreambox!) tuner to upload & install a image by computer browser.
Be shure you only do this if you want to reflash the Enigma2 tuner. Because your Enigma2 tuner will boot with DHCP active so that you can upload a new image by browser on a computer.
mount /boot -o remount,rw
rm /boot/*
reboot



To flash an image using telnet.
This method will only work with a .img image file.
  1. Rename the image file to backup.img
  2. FTP the image file to the /tmp folder on the Enigma2 tuner

Telnet to your box and paste the following command:
cd /tmp && eraseall /dev/mtd/3 && cp backup.img /dev/mtd/3 && reboot



To backup an image using telnet.
cat /dev/mtd/3 » /tmp/backup.img

  1. FTP to the box and navigate to the /tmp
  2. Here you will find the backup.img file.


To copy an image from your PC to the Enigma2 tuner via telnet.
First of all, you need to have a mounted directory from your PC. Make sure you have the image.img file in your mounted directory on your PC. Telnet to the Enigma2 tuner and paste this command:
cp /hdd/movie/image.img /tmp/image.img

The img will be copied from your mounted directory to the /tmp folder on the Enigma2 tuner ready to be flashed.


Dreambox DM8000: Changing Oled display brightness.
Check brightness setting:
cat /proc/stb/lcd/oled_brightness

Configure brightness setting (between 0-255, as example 30)
echo 30 » /proc/stb/lcd/oled_brightness
