当你在使用 strace 命令跟踪某个程序的执行时,如果遇到 strace: exec: permission denied 错误,这通常意味着 strace 在尝试执行被跟踪的程序时没有足够的权限。以下是一些解决这个问题的步骤: 确认strace命令和所需跟踪的程序是否具有执行权限: 确保strace 命令本身具有执行权限。可以通过运行 ls -l $(which strace...

1 步骤一：登陆Linux系统执行ls命令时，报错-bash: /bin/ls: Permission denied，但是在root用户下执行正常 2 步骤二：使用strace ls命令查看系统调用，出现如下日志报错，看到系统在exec执行拒绝，很可能是没有执行权限导致[oracle@k8s ~]$ strace lsexecve("/bin/ls", ["ls"], [/* 18 vars */]) = -1...

1su -s /bin/sh -c exec nova-compute --flagfile=/etc/nova/nova.conf --flagfile=/etc/nova/nova-compute.conf nova 即表示使用nova用户,在sh交互下,执行nova-compute程序。也就是说,在nova用户下已经没有跑通,但是在nova用户使用cli的情况下又可以跑通。这样奇怪的问题也是极其罕见的。
具体指代的系统调用主要是创建进程(fork 系列)、执行新程序(exec 系列)、回收子进程(wait 系列)相关的一些列系统调用。 8、跟踪所有网络相关的系统调用 # strace -e trace=%network ping -c 1 github.com socket(AF_INET, SOCK_DGRAM, IPPROTO_ICMP) = -1 EACCES (Permission denied) socket(AF_INET, ...
