目錄加密……

最近在測試upstart開機自動啟動服務時遇到一個麻煩… 一直告訴我無法access該目錄…. 以為是upstart寫錯~一值修正… 後來才發現是目錄被加密……所以無法被access… 記起來,下次要小心 /home/cowman/.Private on /home/cowman type ecryptfs (ecryptfs_check_dev_ruid,ecryptfs_cipher=aes,ecryptfs_key_bytes=12,ecryptfs_unlink_sigs,ecryptfs_sig=123,ecryptfs_fnek_sig=123)

bridge firewall use iptables to contorl packet

因為預設的bridge firewall ploicy是bypass…屬於通透的firewall (layer 2) 所以在layer 3的iptables就管不到他了 這時候可以修正 /etc/sysctl.conf 內的設定,增加下面的資料 針對bridge進行過濾 net.bridge.bridge-nf-call-iptables = 1 net.bridge.bridge-nf-call-ip6tables = 1 net.bridge.bridge-nf-call-arptables = 1 然後使用 sysctl -p /etc/sysctl.conf 執行 也可以透過 sysctl -a | grep bridge-nf 觀看目前相關設定
