我有一份来自瓦兰的产出:
==4836== 10,232 bytes in 1 blocks are still reachable in loss record 1 of 1
==4836== at 0x4C2779D: malloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so)
==4836== by 0x401865: thrt() (main.cpp:221)
==4836== by 0x4048B1: main (tester.cpp:35)
==4836==是什么意思?
0x4C2779D
在linux上,man2open,我得到了关于以下标志的解释:
S_IRWXU
00700 user (file owner) has read, write and execute permission
S_IRUSR
00400 user has read permission
S_IWUSR
00200 user has write permission
S_IXUSR
00100 user has execute permission
S_IRWXG
在下面的配置中,aaa是什么意思?
aaa authentication login CON local
aaa authentication login VTY group VTY local
aaa authentication dot1x default group DOT1x
aaa authorization exec VTY group VTY if-authenticated
