ubuntu11+ eclipse不能附加進程調試的解決方案

You can temporarily disable this restriction (and revert to the old behaviour allowing your user to ptrace (gdb) any of their other processes) by doing:


echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope
To permanently allow it edit /etc/sysctl.d/10-ptrace.conf and change the line:


kernel.yama.ptrace_scope = 1
To read


kernel.yama.ptrace_scope = 0

For some background on why this change was made, see the Ubuntu wiki
