I would like to access the PRS-T1 via telnet.
I found a free apk called
Android Developer Shell, which install just fine.
After bringing up the network connection and starting the app, it tells me, that it is listening on it's (correct) ip address on port 3550. However, trying to reach it from my Linux box fails.
Checking further, I can't even ping the reader, while I can ping the Linux box ok from the reader.
Digging a bit deeper, I found out, that there is quite a lot of commands available through busybox (including telnetd, actually, but I don't know yet, how to start it here), so I even could login on my Linux box from the reader.
This is my first Android device, so forgive me for asking maybe stupid questions. Is there some sort of firewall running on the reader blocking any kind of incoming traffic? I can ping and access several machines within my LAN/WLAN just fine, my router shows the reader as connected, so it stunns me, that I even can't ping it.
