I have been trying to enable root telnet on an mr5100.
These are the commands I have been trying. They are all accepted but telnet on port 23 still does not work regardless if i test it over USB or ethernet
Code: Select all
AT!OPENLOCK?
AT!OPENLOCK="code from py script"
AT!SETCND="mypw"
AT!TELEN=1 - enable telnet
AT!CUSTOM="RDENABLE", 1
Is there an additional steps for the MR5100?

Telnet is enabled by default but ttl is difficult to set up on this device.

After enabling telnet with the root shell, enabling TTL was simple with these commands:
Code: Select all
echo "iptables -t mangle -I POSTROUTING -o rmnet_data0 -j TTL --ttl-set 64" > /etc/init.d/ttl.sh
echo "ip6tables -t mangle -I POSTROUTING -o rmnet_data0 -j HL --hl-set 64" >> /etc/init.d/ttl.sh
chmod 755 /etc/init.d/ttl.sh
ln -s /etc/init.d/ttl.sh /etc/rc5.d/S98ttl

Refers to the sierrakeygen.py script, which can be found at this link:

I tried this and it doesn't set the commands after reboot. On the MR1100 you can add a line to /etc/init.d/rmnologin.sh and it will do it on boot, but that file doesn't exist and it hasn't worked on any of the files I've tried (so far /etc/init/late_init.sh as well as /etc/init.d/varrw.sh)
Any ideas?

Call the ttl.sh from early_init.sh using
/bin/sh /etc/init.d/ttl.sh

Update, tried a few more things and was able to get it to work after boot using /etc/init/early_init.sh using the following at the end after the final lines in the default:
Code: Select all
#TTL modification
sleep 0.5
sh /etc/init.d/ttl.sh
Once I test it with the SIM and check the data report I’ll report back

Was able to test with T-Mobile and it works perfectly fine. I did have to factory reset due to a glitched web panel but it persisted after reset (imei didn’t but that is easy).

Does anyone have the script for this link that is no longer available? I am trying to change ttl
I am also trying to follow this guide
https://parkercs.tech/netgear-mr1100-hotspot/ but cant get the script.
-thank you!
