👩🏻✈️Permissiveモードで ausearch -m avc するの、すこ✩ #SELinux
SELinuxモードは、DisabledとEnforcingの２つだと思っているあなた
実は動作モードは３つあります。
Permissiveモードを是非ご検討ください
これを使うとSELinuxとの距離がグッと縮まります
ConoHa: CentOS Stream 10
SELinux = Disabled💢
AWS: AmazonLinux2023 AMI
SELinux = Permissive🤔
AWS: CentOS Stream 8 AMI
#SELinux = Enforcing(MLS)✨
[yuriko@jumphost-arm ~]$ sudo setenforce 0
setenforce: setenforce() failed
[yuriko@jumphost-arm ~]$ seinfo
Statistics for policy file: /sys/fs/selinux/policy
Policy Version: 31 (MLS enabled)

っと思ってたら、まさかのMLS(軍用)効いてたｗｗ
最近 #SELinux RBAC環境で su - してなさ過ぎて手順忘れてたｗ パスワード正しいハズなのに入れないぞ・・・？ と思ってたら、ロール切替忘れてるっていう・・・
sudo -r sysadm_r su -
でOK!!🙋🏻♀️
