Termux Skill
Purpose
Device interaction via SSH/Termux for the Mali-G77-MC9 reverse engineering project.
Connection
SSH into Termux (primary method)
ssh -p 8022 u0_a375@localhost
Run as root
su -c 'command'
Workflow
1. Push code to device
scp -P 8022 src/kbase/test.c u0_a375@localhost:/data/data/com.termux/files/home/
2. Compile on device
ssh -p 8022 u0_a375@localhost "cd /data/data/com.termux/files/home && gcc -o test test.c"
3. Run on device (as root)
ssh -p 8022 u0_a375@localhost "su -c /data/data/com.termux/files/home/test"
4. Combined push, compile, run
scp -P 8022 src/kbase/test.c u0_a375@localhost:/data/data/com.termux/files/home/ && \
ssh -p 8022 u0_a375@localhost "cd /data/data/com.termux/files/home && gcc -o test test.c && su -c ./test"
Working Directory
/data/data/com.termux/files/home/
Debug Commands
Check kernel messages
ssh -p 8022 u0_a375@localhost "su -c 'dmesg | tail -50'"
List files
ssh -p 8022 u0_a375@localhost "ls -la /data/data/com.termux/files/home/"
Check GPU state
ssh -p 8022 u0_a375@localhost "su -c 'cat /sys/class/misc/mali0/device/gpuinfo'"
ssh -p 8022 u0_a371@localhost "su -c 'cat /sys/kernel/ged/hal/gpu_power_state'"
Check processes using /dev/mali0
ssh -p 8022 u0_a375@localhost "su -c 'ls -la /proc/*/fd/* 2>/dev/null | grep mali0'"
Strace a process using mali0
ssh -p 8022 u0_a375@localhost 'su -c "/data/data/com.termux/files/usr/bin/strace -f -e trace=ioctl -p PID 2>&1" | grep mali0'
Key Notes
- Use SSH with port 8022
- Always run test programs with
su -c for root privileges
- Working directory on device is
/data/data/com.termux/files/home/
- GCC is available in Termux for on-device compilation
- strace binary is at
/data/data/com.termux/files/usr/bin/strace
