iOS - ./fsmon-ios -p [pid] always give an "invalid argument" error

[rustymagnet3000]

Here is what I did:

• Downloaded the zip from: [https://github.com/nowsecure/fsmon/]

• expand zip and run make iOS on your Mac Book

• Use a tool to copy file over to Jailbroken device.


• chmod 755 fsmon-ios to enable execution.

• ./fsmon-ios -L list the systems fs-mon can observe. WORKS.


• ./fsmon-ios -v smoktest it displays the version. WORKS.

• ./fsmon-ios -p [pid] FAILS.

The error I received was:
ioctl: Invalid argument
fdclone: Invalid argument

@trufae this is probably a "user error". Sorry, if it is!

PS - my jailbroken device is old. a non-64 bit ARM (iPhone 4S).
