由上述資料及參考 http://linux.vbird.org/linux_server/0110network_basic.php#whatisnetwork_osi

(1)是否為 Layer 5會談層 (Session Layer), 這樣算惡意嗎?
(2)只設定記錄一筆,可否看出什端倪?
(2)設定沒指定port,是否即記錄全部 port?
Thanks.

在 /var/log/apache2/access.log 中常看到這樣訊息...

網路上查得 http://panda.ks.edu.tw/http_ping.htm

是否在抓取網站所有資料?

如果是,是不是給封了好?

Thanks.

Linux 討論版 / 回覆: php執行時間?
« 於: 2010-08-27 16:14 »
[attachment=1]

這個功能在論壇後台設定中可以關掉或是選擇其它顯示方式
主要是第一時間可清楚知道server負荷,產生首頁所花的時間,及查詢總量.

嗯,如果懷疑是mysql,那參考宗董這篇http://plog.longwin.com.tw/post/1/234來找找看問題。mysql cache沒記錯的話是用query string做hash key,容量有限,查詢結果超過cacahe就沒用,而且有新的query就可能被清掉...看你的使用狀況啦,很可能開了也沒有很大的效果。

Thanks.

要測執行時間, 不要光是跑這種無意義的迴圈, 應該去測有『內容』的 php 碼
謝謝,
簡單的測法,似乎無法檢測php的執行效率.

開xdebug做profiling可能比較有用吧?

...我想你可能只是想在網頁最下方顯示「本頁花了xxxx秒」這樣的訊息...那就在程式開始與結束包這些東西就可以了。不過要搭配template的話,使用$timer->timeElapsed()可能會比較有彈性。

小弟使用的IPB論壇程式,在首頁底下會有執行時間的訊息

因為自己的跟其他使用者,平均都差近4倍的時間

其他論壇
[attachment=1]

自己的主論壇,MySQL資料多
[attachment=2]

自己的測試論壇,MySQL資料非常少
[attachment=3]

當然論壇程式是除了論壇程式本身設定外,php , MySQL,這兩者也應該都會有影響

php加裝測試mem_cache模組,或 eAccesalator 或 APC 都無效.

MySQL也有啟用query cache

但似乎都沒改善,所以再想是否有什麼可測一下php ,MySQL的執行效率?

問過客服,雖稱有客戶使用過外接式-3.5"-1TB是OK的,但煩其查資料至今仍無消息!

但市售2.5"的行動碟是OK的.

試過創見-2.5"-320G or 500G 都OK.

15
大通 HDR-6200 , 參考 >> http://www.px.com.tw/c/p03-Hotpro-1.php

目前使用創見 320G 行動碟是OK的.

有人使用過更大容量的嗎?

如 1TB , 1.5TB,是什廠牌型號可適用??

因昨買了 WD My Book 1.5TB 抓不到阿!

Thanks.

實測後應該有效,可以連下方連結

http://forum.ipb.tw

連上後,按著F5不放 ,一直到出現 Forbidden頁面,一般是5~6次,而等待幾分鐘後再按一次,即可再次正常顯示頁面.

入侵IP所查記錄明顯與前三者不同,即使是bot,也非善類,只是覺得應該不是bot.

目前處理方式:
(1)先將網段封鎖 58.60.0.0 - 58.63.255.255
(2)安裝 libapache2-mod-evasive ,
     參考 => http://www.debianadmin.com/how-to-protect-apache-against-dosddos-or-brute-force-attacks.html
     同時依模組所附安裝說明,在http.conf加入
代碼: [選擇]
    <IfModule mod_evasive20.c>
    DOSHashTableSize    3097
    DOSPageCount        2
    DOSSiteCount        50
    DOSPageInterval     1
    DOSSiteInterval     1
    DOSBlockingPeriod   10
    DOSLogDir "/var/lock/mod_evasive"
   </IfModule>
(3)在iptables中加入
    
代碼: [選擇]
iptables -A FORWARD -i $EXTIF -p tcp --syn -m limit --limit 1/s -j ACCEPT     參考 => http://linux.vbird.org/linux_server/0250simple_firewall.php#local_script
(4)如上述(1)中封鎖網段 58.60.0.0 - 58.63.255.255,只是這樣封鎖,他的目的也是達到了,讓一些IP上不了網站
    也就是說,如果(2),(3)有效,是不是就可以不必封鎖該IP了.

不知是否妥當?

Thanks.

是以Samba來作資料夾分享沒錯,資料夾權限也有設定,但即使加了ACL,仍然達不到上述需求.

如何讓資料夾只能新增檔案,不允許覆及刪除

21
OS:Debian 5.0.3

在公司部門需求,每個人需要自行將圖檔.dwg歸檔到特定區域網路分享資料夾test中

在這test資料夾中,每個人只能將自己圖檔copy新增檔案於其中,但若已經有相同檔名則不允許覆蓋,

更不能刪除資料夾中所有檔案.

參考鳥哥網站,有關檔案隱藏屬性 >> http://linux.vbird.org/linux_basic/0220filemanager.php#chattr

[root@www ~]# chattr [+-=][ASacdistu] 檔案或目錄名稱
選項與參數:
+   :增加某一個特殊參數,其他原本存在參數則不動。
-   :移除某一個特殊參數,其他原本存在參數則不動。
=   :設定一定,且僅有後面接的參數

A  :當設定了 A 這個屬性時,若你有存取此檔案(或目錄)時,他的存取時間 atime
     將不會被修改,可避免I/O較慢的機器過度的存取磁碟。這對速度較慢的電腦有幫助
S  :一般檔案是非同步寫入磁碟的(原理請參考第五章sync的說明),如果加上 S 這個
     屬性時,當你進行任何檔案的修改,該更動會『同步』寫入磁碟中。
a  :當設定 a 之後,這個檔案將只能增加資料,而不能刪除也不能修改資料,只有root
     才能設定這個屬性。

c  :這個屬性設定之後,將會自動的將此檔案『壓縮』,在讀取的時候將會自動解壓縮,
     但是在儲存的時候,將會先進行壓縮後再儲存(看來對於大檔案似乎蠻有用的!)
d  :當 dump 程序被執行的時候,設定 d 屬性將可使該檔案(或目錄)不會被 dump 備份
i  :這個 i 可就很厲害了!他可以讓一個檔案『不能被刪除、改名、設定連結也無法
     寫入或新增資料!』對於系統安全性有相當大的助益!只有 root 能設定此屬性
s  :當檔案設定了 s 屬性時,如果這個檔案被刪除,他將會被完全的移除出這個硬碟
     空間,所以如果誤刪了,完全無法救回來了喔!
u  :與 s 相反的,當使用 u 來設定檔案時,如果該檔案被刪除了,則資料內容其實還
     存在磁碟中,可以使用來救援該檔案喔!
注意:屬性設定常見的是 a 與 i 的設定值,而且很多設定值必須要身為 root 才能設定

ATTRIBUTES
       When a file with the 'A' attribute set is accessed, its atime record is
       not modified.  This avoids a certain amount of disk I/O for laptop sys-
       tems.

       A  file  with the `a' attribute set can only be open in append mode for
       writing.   Only   the   superuser   or   a   process   possessing   the
       CAP_LINUX_IMMUTABLE capability can set or clear this attribute.

似乎也無法達到需求?


測試一下test資料夾
代碼: [選擇]
# chattr +a test
# lsattr
-----a------------- ./test

結果無法copy檔案到test資料夾中?!

How to ?
Thanks.

OS:Debian 5.0.x

不寫入access.log
在/etc/apache2/sites-available/default中
可以這樣設定
代碼: [選擇]
.............................
SetEnvIf Remote_Addr "66\.249\.67\." dontlog
............................
.............................
.............................
CustomLog /var/log/apache2/access.log combined env=!dontlog
...................................

但如何讓這信任的IP,也不寫入 error.log
在/etc/apache2/sites-available/default
有這段
代碼: [選擇]
ErrorLog /var/log/apache2/error.log
謝謝.

先請kenduest 老大消消火...

其實我已經看很多了,這類的新手經常沒頭沒腦的丟問題出來
也沒有很明白的交待一些事情,就想說有沒有人可以幫忙解決問題
我之前看多了,說老實話,也就不大想太認真來看待他們的問題

所以,樓主那台Linux Router我連理都不想理 ..因為除錯的經驗
已經告訴我,問題點可能不在那台Linux Router ...

反而是硬體的問題比較有可能... 所以我之前的回覆已經有提示這一段了
樓主後來的檢查也是指向我的看法 ...

說老實話,這類的問題處理多了, 也覺得沒什麼挑戰性!!

樓主這樣設定IPTables就原諒他吧 , 說老實話 ,論壇裡頭能夠真正瞭解
IPTables設定方法的人,我想不多 , 也數得出來... 因為大部份的人都是一樣
拿個example 來套用能動,就萬事OK了...況且netfilter那五個chain的流程
能搞得清楚的人就算不錯了... 還能指望現在的新手能提供什麼樣的資訊
我想都不敢想... 不指望了!!

我以後的態度大概都是這樣了,對於發文次數不多的人,求救求解答的人
我頂多是給提示,不會參與討論,也不用太認真來看待他們的問題!!


感謝指教,會再更用心學習.

請問不通時候,iptables firewall 與 ipv4 forwarding 數值為何?我想是要看這個吧。

還有你 fw 一堆根本不需要的設定,比方為何一堆 INPUT 阻擋限制?你不是在內網測試嗎... (除非你實際網路非如此,你有少交代一些事情)

再者你只是測試 ip forwarding 功能而已,這兩段要通就是單純封包轉送不包含 nat,但是你都設定了... 這樣只會把問題複雜化。

基本上,你不需要有任何 iptables 設定,純 ipv4 forwarding 不需要特別到 iptables 內有其他 rule 設定項目。只要確認 default policy 為 ACCEPT,系統面 ipv4 forwarding 數值為 1,兩個不同網段 gw 都指向 linux 各自連結 ip 即可。

網路問題請應該用單純環境去測試,不要把問題複雜化這樣。

如圖Linux Router有WWW,FTP...等對外服務,所以才會加入很的 INPUT...DROP
這些IP從access.log中觀查出,企圖不友善.

而Linux Router <---|ES-108A|---> PC2 這段是內部網路沒錯,上述iptables是設於Linux Router中

真是抱歉,問題問的太複雜了,應該是這樣問>>>

(Q)請問ES-108A交換器+PC2會因關掉電源重開後,設定會跑掉嗎?

(A)不會,除非硬體,如網卡出了問題.

26
奇怪了....

你不是已經縮小問題區域了嗎?? 還問why ??

天下沒有不會壞的PC 主機,也沒有不會壞的網路線,更沒有不會壞的網路卡!!
當然switch也在內啊.... 搞不好就是那麼巧,swich port要壞不壞....都有可能啊!!

這種非網管的設備,誰知道功能到底是不是正常?

問題解決了,是網卡D-Kink DE-530跟舊電腦問題,改設另一台電腦為Linux Router,設定都一樣

關掉Switch & PC2 ,再重新啟動後, PC2 連內外網路都正常了.

27
就診斷一下吧...
1. 當時候 linux 可以 ping 內與外兩個網段嗎?
2. 當時候 ipv4 forwarding 內容數值是多少有無異動?
3. 當時候 firewall 設定內容為何?iptables-save 輸出寫啥

感謝指引方向:
1. 當時候 linux 可ping到兩網段.
2. 當時候 ipv4 forwarding 內容數值為 1 , 沒改變.
3. iptables-save 輸出如下

iptables設定係參考 鳥哥 >> http://linux.vbird.org/linux_server/0250simple_firewall.php#local_script

===================================================================================================

Hi,anderson1127 兄

感謝指導,個人會再多多念書,目前是以鳥哥的文件為學習基礎 >> http://linux.vbird.org

當然能否融會貫通,這是最大的問題.

若有前輩能不吝指引方向,相信能學到更多的技巧&經驗.

Thanks.

感謝回覆.

所以是這台ES-108A的特性,或者是說故障,(即使新品,也試了不同的port).

鳥哥文中 http://linux.vbird.org/linux_server/0230router.php#route_static

有提到這段

引用
3. 啟動 IP 轉遞
[root@linux ~]# echo "1" > /proc/sys/net/ipv4/ip_forward
# 上述指令如果沒有問題,將他加入 /etc/rc.d/rc.local 當中去!

它不會因 ES-108A 關電源而失效是嗎?

因為訥悶,為何Linux Router重開機後,一切都正常?

Thanks.

以交換器來練習區域網路設定

購買交換器 >> 合勤 Zyxel ES-108A >> http://www.zyxel.com.tw/zyxel/product/prod_detail.php?no=0000106

參考鳥哥文章 >> http://linux.vbird.org/linux_server/0230router.php#route_static

設定類似如文中圖示:


發生的問題是:

狀況一.

      如圖中Linux Router + ES-108A + PC2 硬體接妥,設定也ok,但 PC2 ping不到Linux Router

      若 Linux Router重開機後,則PC2可ping到Linux Router


狀況二.
    
      將PC2關機,同時也關掉ES-108A電源後,再重開,PC2 又ping不到Linux Router

      但Linux Router再重開機後,PC2 又可ping到Linux Router

狀況三.

      若是ES-108A電源不關,只重新啟動PC2,PC2可ping到Linux Router.

Why?

Thanks.

這種狀況的確很少見,不過使用了這幾年來,只碰到這一次,算神奇了.  ;D
