DDPAI Mola N3 - telnet

[Lucian84]

Hi! I'm trying to start telnetd using update/update.sh script on SD card but it's not working as it should. Telnetd is starting, I see port 23 open for a short period of time then it closes. I think telnetd is being terminated somehow... Did anyone manage to get telnet working on this camera?
Thank you!

Telnetd is starting, I see port 23 open for a short period of time then it closes. I think telnetd is being terminated somehow...

telnetd needs /dev/pts for opening the (pseudo-)terminal link and crashes if it is not there. Mount /dev/pts before starting telnetd and it will work (at least on old good Mola N3).

@helg I've tried your recommendation, but still no luck, maybe I'm doing something wrong. Here is my update.sh contents:
#!/bin/sh
mkdir /dev/pts
mount -t devpts devpts /dev/pts
/usr/sbin/telnetd -p 23 &

Thank you for your support!

Looks ok to me. You can check 'dmesg' output, 'cat /proc/mounts' and also enable full 'DDPaiDebugOld' logging.

Finally telnet is working!
I was creating the update.sh file on windows, with standard CRLF endings, and it seems that the camera os doesn't like that I've converted the file to unix end of line (LF) and everything is working!
Thank you @helg for helping!
