vsftpd伺服器死機
由於公司需要，本人用RHEL5架設了一台VSFTPD伺服器,但發現用過一段時間后，死機....死機的時候，屏幕出現一段文字....那段文字我沒有截圖,我把死機之前的日誌貼出來，麻煩大家幫我看看，這是本人第一次搭建FTP伺服器,先謝謝大家了.

《解決方案》
似乎和系統的穩定性有關.
實際的時候是不是 "kenel panic....."
感覺不是vsftpd 的問題, 應該是系統的原因.
可以嘗試換換網卡什麼的.
另外你的ftp 放在公網上么?? 危險!!!
小心泄露公司機密哦.

我是第一次建立FTP伺服器,只是有一點關於網路安全的常識，我的伺服器還有哪些地方需要改進的嗎?請樓上的朋友賜教，非常感謝!

還是指我把日誌貼出來是泄露機密=.=
