get a ssh server app, like the very excellent SSHDroid:
unofficially: (if you trust this server)
sha512sum SSHDroid_2.1.2_44.apk 535ec2e1ae2153fe5cb99bcd5ebaaf580b4d1358c77c9bb134f0ecde4601dc0f53c918b95c856a92d8373309ea95e83052a93529a49ef35c196819517b40bd2e SSHDroid_2.1.2_44.apk
if you are running a custom rom, have rooted your phone and AFWall+ Firewall installed… you will need to allow „(Root) Apps with Root-rights“ in LAN
(DO NOT FORGET TO CLICK THE … 3x DOTS TOP RIGHT CORNER AND CLICK ON „APPLY“ or your rules will not be applied!)
set a password… default passwords are evil.
go back to home screen, stop/start the SSHDroid (maybe even try to restart your phone)
make sure it shows „ready“ / „bereit“
… with the password you specified in the options.
# now you can do cool things like htop ("taskmanager") # dmesg (boot messages) # checkout what kernel it is running uname -a Linux localhost 3.10.73-ge8c57cd #1 SMP PREEMPT Sun Feb 24 06:35:00 UTC 2019 armv8l # checkout apps and connections netstat -pantu # so you can see the ip of the telegram server tcp 0 0 192.168.0.101:45060 126.96.36.199:80 ESTABLISHED 9153/org.telegram.messenger # this is a rather strange connection... # guess it is just the ip that SSHDroid tries to load adds from tcp 1 0 192.168.0.101:46383 188.8.131.52:80 CLOSE_WAIT 13865/berserker.android.apps.sshdroid
or just show all files of the / root partition:
interesting to look at…
PS: ping can work, but maybe is blocked.
