[問題] 更新3.2.0-37 kernel後 ssh 怪怪的
這件事情發生在昨天
我更新完3.2.0-37的kernel後
發現在開機後不登入桌面或是CLI的狀況下
用ssh遠端連線到機器
會顯示ssh: connect to host a.b.c.d port xxxxx: No route to host
一直要到機器的CLI登入後或是桌面登入後
遠端ssh連過來機器才會看到要求輸入密碼的畫面
不知道是出了什麼問題
理論上就算沒有進桌面
沒有登入CLI
遠端是可以直接ssh連線進來的不是嗎?
by the way.....
機器是ASUS F9E
OS版本是Mint 13 KDE
Thanks for everybody's help :D

um.....我平常是有在用fedora
但是fedora我只用在file server
有桌面需求我大多都用mint
不好意思造成您的誤會 <( _ _ )>

誒....這台的防火牆前端設定程式我是用ufw
而且我沒有裝ufw的GUI
之前本地端沒有登入也可以從遠端登入沒問題

um...在換kernel前他本地端還沒登入就會跑DHCP了
而且也有辦法遠端連線

我在更新的時候
他確實有問我要不要更換新版本的script
似乎路徑是在/etc底下
或許跟您說的有關
那....如果是這樣的話
我應該怎麼把ssh連線的設定改回來呢？
先謝謝各位了

我記得他問我要不要改變按Y或是N的時候
有看到/etc/issue
但是我看了issue裏面沒有相關的東西
其他的幾個目錄底下我也還沒看到有會影響到ssh登入的script
