Failed to reopen debug port for Selected Client to XXXX

這是 Debian-based 的 Linux 特有的 bug...
事情發生在安裝好 sun-java6-jdk, eclipse, ADT 之後，打開 Window -> Android SDK and AVD manager 時，Eclipse 的 Console 視窗會開始一直跳出下面這樣的訊息

[2010-03-04 23:04:42 - ddms]Failed to reopen debug port for Selected Client to: 8700

拜過谷歌大神後，得到解法如下

sudo sysctl -w net.ipv6.bindv6only=0

重開機後也要保持設定值，則修改 /etc/sysctl.d/bindv6only.conf 裡的的設定值為

net.ipv6.bindv6only = 0

原因請參考下面這兩篇...
