Unable to attach to pid 11144: Invalid argument
Chcel som si prehodiť do terminálu cele ssh pripojenie, pričom ssh je spuštané so skriptu (PID 11144)...
Někde (třeba Ubuntu 14.04) můžete dostat hlášku:
Unable to attach to pid 18673: Operation not permitted
The kernel denied permission while attaching. If your uid matches
the target's, check the value of /proc/sys/kernel/yama/ptrace_scope.
For more information, see /etc/sysctl.d/10-ptrace.conf
