# 將 security 從 user 改為 share ﹕
security = user
; security = share
然後﹐還要將下面兩行前面的註解符號拿掉﹕
encrypt passwords = yes
smb passwd file = /etc/samba/smbpasswd
但這還沒完成﹐您還需執行如下命令﹕
touch /etc/samba/smbpasswd
chmod 600 /etc/samba/smbpasswd
smbpasswd -a kenny
New SMB password:
Retype new SMB password:
照資料做可是.....無法存取
連假如您碰到問題﹐如下面這個﹕ 沒有資源使用權
的畫面都沒出現
只有出現該帳戶沒有權力從該站登入
請有經驗的人幫幫小弟
謝謝

1.下載所需檔案
安裝snort需要用到libpcap,故請自行下載最新的libpcap及snort,
此安裝說明使用的版本是:
snort-1.6.tar.gz(亦可使用rpm版,snort-1.6-0.i386.rpm)
libpcap.tar.Z(目前最新為0.4版)
2.進行安裝
首先,先將libpcap裝起來:
# tar zxvf libpcap.tar.Z (將libpcap.tar.Z解壓縮)
# cd libpcap-0.4 (到libpcap目錄下)
# cp Makefile.in Makefile
# ./configure
# make
# make install
# make install-incl (某些情況下,若發生error,你可能必須自己建目錄)
# make install-man
# make clean
再來安裝snort:
# tar zxvf snort-1.6.tar.gz
# cd snort-1.6
# ./configure
# make
# make install
# make clean
3.啟動snort
首先,snort安裝好後,你可以下 snort -v 指令來看看snort是否可正常運行.
其次,在snort目錄下有一個snort-lib檔,這是default的主要設定檔,
你可以看一下裡面內容並做適當的修改,這個檔案會去include其他的設定檔,
同樣的,你也可以適當的去修改這些檔案,不過你得先弄懂snort的規則!
我的啟動方法是:
cd snort-1.6
snort -c snort-lib
.....start run
initalizing network interface
...........
.............keyword | perprocessor 偵測網路上的異常封包還是解碼?
http_decode : 0x1234567
-c (指定snort依snort-lib設定檔的設定運行)
我的snort-lib設定如下
-------------------------------------------------------------------------
preprocessor http_decode: 80 8080
preprocessor minfrag: 128
var HOME_NET xx.xx.xx.xx/xx (請填自己想偵測的網域)
preprocessor portscan: $HOME_NET 7 2 /var/log/snort/portscan.log
preprocessor portscan-ignorehosts: $HOME_NET
include web-lib
include overflow-lib
include misc-lib
include scan-lib
include backdoor-lib
alert icmp !$HOME_NET any -> $HOME_NET any (ipopts: lsrr; msg: "Source routed packet";)
alert icmp !$HOME_NET any -> $HOME_NET any (ipopts: ssrr; msg: "Source routed packet";)
alert tcp !$HOME_NET any -> $HOME_NET any (ipopts: lsrr; msg: "Source routed packet";)
alert tcp !$HOME_NET any -> $HOME_NET any (ipopts: ssrr; msg: "Source routed packet";)
alert udp !$HOME_NET any -> $HOME_NET any (ipopts: lsrr; msg: "Source routed packet";)
alert udp !$HOME_NET any -> $HOME_NET any (ipopts: ssrr; msg: "Source routed packet";)
alert tcp any any -> $HOME_NET 6667 (flags: PA; content: "USER "; nocase; offset:0; depth:5; content: " "; offset:11; depth:
1; content: " "; offset: 18; depth:1; content: " :"; offset: 26; depth: 2; msg: "PrettyPark activity!";)
----------------------------------------------------------------------------
如此一來,snort就會把偵測到的警告訊息存到/var/log/snort.alert及/var/log/snort/下,
接下來,就看你如何運用了!! =================>可是沒有var/log/snort.alert及/var/log/snort/

我把它打到 /etc/cron.daiily/chk_suid.sh 裡去
#!/bin/bash
ORIG_LIST=/root/suid.list
NEW_LIST=/root/suid.new
echo
find / -perm +u+s -exec ls -l {} \; > $NEW_LIST
if diff $ORIG_LIST $NEW_LIST

echo
echo ......這還是不明白為何echo 要兩個
chmod +x /etc/cron.daily/chk_suid.sh
# /etc/cron.daily/chk_suid.sh

然後加進去
ldapadd -x -f use1.ldif -D "cn=root,o=fortop,c=tw" -w 123456
-------->>>adding new entry "cn=root,o=fortop,c=tw"
ldap_add: object class violation additional info: attribute ' mail' not allowed
ldif_record()=65
請指導一下
謝謝

我先vi /etc/ldap/slapd.conf,我改了
database ldbm
suffix "o=fortop,c=tw"

rootpw 123456
之後我再到/etc/ldap中建了一個檔
vi use1.ldif內容如下
dn: cn=root, o=fortop, c=tw
objectClass= person
cn: David Kao
sn: Kao
Userpassword: 123456
mail: redhat.linux@msa.hinet.net.
telephoneNimber: 123456789
再來我就要新增user
ldapadd -x use1.ldif -D "cn=root,o=fortop,c=tw" -w
------->no such attribute
請大大幫我看一下.

輸出符何www的內容.在來排序.再來列行數
print $5====不白明
