utelnetd - yet another remote shell application

[rkomar]

It bothers me that I can't get a nice shell using ssh anymore under the newest firmware versions. So I looked around, and found that @reader42 already ported the utelnetd telnet server to PocketBook devices. Very nice! Using his source code, I packaged up versions for the older 3XX and the newer Pro/360+ devices. I've also included a copy of bash in each package. Pick the right zip file for your device, and unzip the contents in /mnt/ext1/.

Instead of using the Inkview application that @reader42 provided for controlling the daemon, I used a couple of shell scripts instead (utelnetd_start.app and utelnetd_stop.app). I did this because they are smaller, platform-independent, and, most importantly, run in the background. Thus, you can do other stuff on the device while logged in via telnet (which makes it nice for debugging).

Within the Applications tab, click on utelnetd_start to start the server in the background and connect to the net, and click on utelnetd_stop to disconnect from the net and kill the server. While the server is running, you can telnet to the device via port 10000:

telnet <IP-address> 10000

You get a prompt, command history and editting, and even vi behaves nicely.

You can change the port number by editting the applications/utelnetd_start.app script. If you want to put bash somewhere else than /mnt/ext1/system/bin, then you need to rebuild utelnetd for that. Get the sources from: http://sourceforge.net/apps/mediawik...for_PocketBook. I've also uploaded the updated Makefile I used to build utelnetd. You need to change the Makefile if you want to put bash somewhere other than /mnt/ext1/system/bin/.

Thanks @reader42

Edit: I should point out that when you exit the telnet session on the PC, the terminal seems to hang until the server is killed on the device. I don't know how to fix that, so please pipe up anyone that does.

Thank you very much you guys (reader42, rkomar) - it works great!

If I had the find command available for my Pro612 now too, it would be totally awesome.

Greetings

Actually, most of the utility programs in the Debian Lenny armel distribution are compatible with the recent PocketBook devices. You can pretty much copy them to the device and use them in the terminal. Some of the more complex programs may not have all of the libraries available on the device, but even in those cases you can copy the libraries over and play with LD_LIBRARY_PATH to run them. I know that find works, because that was one of the first programs I copied over myself.

You are absolutely right - thanks again
You just made my day.
