sysctl：无法统计 /proc/sys/kernel/exec-shield：没有这样的文件或目录

  • 772

启用 ExecShield 保护 - ExecShield 是用于避免蠕虫和其他问题的安全 Linux 内核补丁。

添加到后

/etc/sysctl 
kernel.exec-shield = 1

收到此错误 sysctl: cannotstat /proc/sys/kernel/exec-shield: No such file or directory

输出 ：

root@ashishk:/home/ashish/MyScripts# sysctl -p

sysctl: cannot stat /proc/sys/kernel/exec-shield: No such file or directory

kernel.randomize_va_space = 1

net.ipv4.conf.all.rp_filter = 1

net.ipv4.conf.default.rp_filter = 1

net.ipv4.icmp_echo_ignore_broadcasts = 1

net.ipv4.conf.all.accept_source_route = 0

net.ipv4.conf.default.accept_source_route = 0

net.ipv4.conf.all.send_redirects = 0

net.ipv4.conf.default.send_redirects = 0

net.ipv4.tcp_syncookies = 1

net.ipv4.tcp_max_syn_backlog = 2048

net.ipv4.tcp_synack_retries = 2

net.ipv4.tcp_syn_retries = 5

net.ipv4.conf.all.log_martians = 1

net.ipv4.icmp_ignore_bogus_error_responses = 1

net.ipv4.conf.all.accept_redirects = 0

net.ipv4.conf.default.accept_redirects = 0

net.ipv4.icmp_echo_ignore_all = 1

net.ipv6.conf.all.disable_ipv6 = 1

net.ipv6.conf.default.disable_ipv6 = 1

net.ipv6.conf.lo.disable_ipv6 = 1

我能知道什么是错的吗？

    c4f4t0r 已经在评论中提供了直接问题的答案，但并不完全准确。

    exec-shield 继续存在；实际删除的是通过 sysctl 设置禁用它的选项
