Lldb debugging using lldb-server on android?-CodePudding

I currently dont have a pc. I have two rooted devices Arm64 host device with Debian rootfs and the device to be debugged which contains the lldb-server binary armv7. I am trying to remote debug my android device using lldb. I pulled the lldb-server binary from àndroid ndk24 and put it in /data/local/tmp. Installed Debian Sid on Another term and apt installed lldb.

I then wifi hotspoted the client device(one with lldb-server) using the host with the linux rootfs.

The commands i ran on server device

./data/local/tmp/lldb-server platform --listen "*:2000"  --server

Checked using netstat and the lldb-server had bound to all addresses(0.0.0.0:2000)

On host(client lldb) device in debian sid terminal i ran:

apt install lldb
lldb
platform select remote-android
platform connect connect://192.168.201.132:2000

Then i get error failed connect port.

However, using Gdb and gdbserver everything worked perfectly. I have tried installing lldb on debian buster but same result and even ran the lldb-server binary on the host(device with debian sid) but same result. Right now im stuck here. How do I solve this?

Help will be greatly appreciated. Thank you.

I dont know why, but lldb-server platform command is broken(mabe in my case) and should have used lldb-server gdbserver like this:

On lldb-server gdbserver command, the stub doesnt allow connections from other ips except the one it is bound to so do this:

iptables -I INPUT -t nat -p tcp -d 192.168.43.1 --dport 2000 -j SNAT --to-source 192.168.43.1:50000
./data/local/tmp/lldb-server g 192.168.43.1:2000

On lldb client do

gdb-remote 192.168.43.1:2000

Then do normal remote debugging.
