Getting the telnetd off of debian...
The i386 version of busybox's telnetd doesn't need inetd, but the armel one does

If it needs inetd, then it isn't telnetd its telnet.
I noticed that in your earlier post, was not sure if that was a typo or not, since you evidently have to pay for each character you type.

telnet: The client
telnetd: The server

inetd: The "super server"
I.E: Starts other programs "on demand"

telnetd, from any provider, will run either as a daemon (the: d) A.K.A: a "service" or may be started on-demand (by inetd or similar).
It only depends on how you configure it, not the arch its built for.

No, I put the busybox binary in /mnt/us and ran /mnt/us/busybox telnetd and it gave some error and aborted.

What did strace have to say?
Did you use a copy of busybox built so that it can be moved from /bin?
What busybox?
From where?
As I posted elsewhere today - my crystal ball is off-line.
Unless you type enough characters to give a decent problem and question statement, don't expect much help from anyone.

@aditya3098: telnetd calls login (at least, busybox telnet does).

The telnetd bundled with the USBNet hack is configured to call the internal busybox login applet, which is patched to grant direct root login without password. You can rip it out of the K4 USBNet package.

I got the busybox from debian (busybox-static for armel) and symlinked it from /mnt/us/busybox to /bin/busybox_custom, and most utils worked just fine. The strace said something about it aborting.

The telnetd workd great, from the usbnet hack, and I found a bunch of other good stuff in there. But I can't figure out how to forward the port.

NiLuJe · 07-12-2012, 01:21 PM

@aditya3098: What do you mean by 'forwarding the port'? Launching a second fg sshd on another port?

Code:

$(which sshd) -d -p 8888

?

Same thing on the client, ssh -vvv root@kindle -p 8888

forwarding the port for telnetd

NiLuJe · 07-12-2012, 10:42 PM

@aditya3098: Still not sure what you mean, exactly, sorry ;D. The telnetd from USBNet doesn't rely on inetd, it's completely standalone. And it listens on the usual port (grep telnet /etc/services == 23 TCP/UDP) :?

aditya3098 · 07-13-2012, 07:31 AM

Sorry, I was just dumb. It works. And I think this stuff should be put in the kt's usbnet hack.

Perhaps "forward" is not being used in its technical sense.
It might well mean that the question being asked is how to allow in-bound connections to telnetd.
(Some router / dsl modems misuse "forward" in this sense.)

If such is the case, then the O.P. wants to know how to open port 23 for in-bound connections in iptables (firewall).

The best place to do that is in the iptables save file, so that the rule is set on every reboot.

I did JUST that.

@aditya3098: I'll probably start working on 'porting' the full USBNet hack to the Touch sometime during the summer, if upstart doesn't drive me crazy before then

What do you mean by "this stuff"?

... Sorry if I'm saying it again, but generally, you should really try to be a bit more verbose in your posts, by including the context of your statements or questions.

(don't get me wrong: this is meant in a constructive way)
