这两天一直在研究AS3，初次使用，由RH73跨越到AS3，确实有很多东西不适应，配置方法也不太一样，下面就我在安装配置时出现的一些问题在这里说明一下
我的系统挂了MYSQL、PHP、APACHE2，做了SQUID和NAT、SAMBA、DHCP、SENDMAIL+SMTP认证、PROFTPD
7、做SQUID
我沿用的RH73的SQUID配置，但在AS3里却遇到了问题
后来仔细看提示才发现，说找不到一个DNS SERVER，奇怪，我的ADSL拨号能PING通www.163.com啊
后来发现/etc/resvol.conf为空，我添加了一个DNS SERVER就行了
我的SQUID做了1000M容量，保存HTTP的1M大小以下的文件，这里就不细说如何配置SQUID了
另外别忘了在iptables里将80端口指向SQUID的端口，我的是默认的3128
8、DHCP
我仍然沿用RH73的dhcpd.conf，结果提示错误，服务无法启动，后来发现需要加个参数
| 引用: |
ddns-update-style ad-hoc; |
我的配置文件如下
| 代码: |
ddns-update-style ad-hoc; max-lease-time -1; default-lease-time -1; option subnet-mask 255.255.255.0; option broadcast-address 255.255.255.255; option routers 192.168.0.1; option domain-name-servers 192.168.0.1,202.106.196.152; option domain-name "platinum.3322.org"; subnet 192.168.0.0 netmask 255.255.255.0 { range 192.168.0.2 192.168.0.100; host platinum { hardware ethernet 00:0a:e6:a9:64:a2; fixed-address 192.168.0.2; } host bchyi { hardware ethernet 00:80:c8:e4:c1:e4; fixed-address 192.168.0.3; filename "/tftpboot/pxelinux.0"; } } |
9、SAMBA
这个是最头疼的，因为这个困惑了我半天的时间
最开始，我沿用RH73的配置文档，发现网上邻居能看见，却无法访问
我的配置文档如下
| 代码: |
[global] client code page = 936 workgroup = HOME server string = Samba Server security = USER encrypt passwords = Yes update encrypted = Yes obey pam restrictions = Yes pam password change = Yes passwd program = /usr/bin/passwd %u passwd chat = *New*password* %n\n *Retype*new*password* %n\n *passwd:*all*authentication*tokens*updated*successfully* unix password sync = Yes log file = /var/log/samba/%m.log max log size = 0 socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 wins proxy = Yes wins support = Yes remote announce = 192.168.0.255 remote browse sync = 192.168.0.255 create mask = 0777 directory mask = 0777 printing = lprng [数据中心] comment = DATACENTER path = /share/DATACENTER read only = No |
于是我将security = DOMAIN改成了security = USER
结果发现能出来了，但是进去以后，英文目录名没问题，中文全是乱码（大方框）
在RH73和RH9里百试百灵的，怎么在AS3里不行了？
于是我ssh，直接进入我的硬盘ls了一下，结果傻了，原来RH73看到的都是中文名字，现在变成了???等东西
……
经好好先生提醒，我想起来了，可能是和字符集有关系，于是补装ttfonts-zh_CN库，结果发现少装了好多东西，关联东西太多，无奈，又重新装系统……
现在好了，ls，发现仍然是???，无奈，选择默认字符集为GB2312，ls，没事了！
/etc/rc.d/init.d/smb restart
回到网上邻居，进入，发现仍然事乱码！
看来和字符集没关系，和SAMBA的配置有关系
testparm发现，client code page = 936这句话在AS3里并不好使，提示这句话错误
难道没办法显示中文了？？？
找了N多资料，在一个老外的论坛了找到了正确配置方法（显示中文的东西竟然在老外论坛里），用这两句话替代：
dos charset=cp936
unix charset=cp936
现在SAMBA能用了，正确的配置文档如下
| 代码: |
[global] dos charset=cp936 unix charset=cp936 workgroup = HOME server string = Samba Server security = USER encrypt passwords = Yes update encrypted = Yes obey pam restrictions = Yes pam password change = Yes passwd program = /usr/bin/passwd %u passwd chat = *New*password* %n\n *Retype*new*password* %n\n *passwd:*all*authentication*tokens*updated*successfully* unix password sync = Yes log file = /var/log/samba/%m.log max log size = 0 socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 wins proxy = Yes wins support = Yes remote announce = 192.168.0.255 remote browse sync = 192.168.0.255 create mask = 0777 directory mask = 0777 printing = lprng [数据中心] comment = DATACENTER path = /share/DATACENTER read only = No |
注意：cp936是微软的磁盘系统中文标准，而gb2312是中国国家中文标准，二者略有不同，在LINUX中使用cp936能更好地与中文磁盘格式兼容
10、PROFTPD
这个对我来说是轻车熟路了，装了个1.2.9（最高版本，目前没漏洞），编译好
直接把配置文档贴出来吧
| 代码: |
# This is a basic ProFTPD configuration file (rename it to # 'proftpd.conf' for actual use. It establishes a single server # and a single anonymous login. It assumes that you have a user/group # "nobody" and "ftp" for normal operation and anon. ServerType standalone DefaultServer on AllowRetrieveRestart on AllowOverwrite on AllowStoreRestart on ServerIdent on "Welcome to PLATINUM's FTP !" DefaultRoot ~ DisplayLogin .welcome DisplayFirstChdir .message UseReverseDNS off IdentLookups off SystemLog /var/log/ftp.syslog TransferLog /var/log/ftp.transferlog TransferRate RETR 20 group hMovie # MaxClientsPerUser 10 "已超过最大上限 10 个guest用户，请少后再试！" # MaxClientsPerHost 4 # Port 21 is the standard FTP port. Port 21 # Umask 022 is a good standard umask to prevent new dirs and files # from being group and world writable. Umask 002 # To prevent DoS attacks, set the maximum number of child processes # to 30. If you need to allow more than 30 concurrent connections # at once, simply increase this value. Note that this ONLY works # in standalone mode, in inetd mode you should use an inetd server # that allows you to limit maximum number of processes per service # (such as xinetd). MaxInstances 30 # Set the user and group under which the server will run. User nobody Group nobody # Normally, we want files to be overwriteable. <Directory /> AllowOverwrite on </Directory> <Directory /share/DATACENTER/电影> <Limit RNFR DELE WRITE> DenyGroup hMovie </Limit> </Directory> <Anonymous ~guest> User guest Group ftp AllowOverwrite on AllowRetrieveRestart on AllowStoreRestart on TransferRate RETR 10 # MaxClientsPerUser 30 "已超过最大上限 30 个guest用户，请少后再试！" # MaxClientsPerHost 4 <Directory /share/ftp/上传目录> Umask 000 <Limit RNFR DELE RETR> DenyAll </Limit> </Directory> </Anonymous> |
11、网络安全问题
服务架好了，网络安全不容忽视
这是我的“反弹式”防火墙
| 代码: |
#! /bin/bash /sbin/modprobe ip_conntrack_ftp /sbin/modprobe ip_nat_ftp /sbin/iptables -F -t filter /sbin/iptables -F -t nat /sbin/iptables -P INPUT ACCEPT /sbin/iptables -P OUTPUT ACCEPT /sbin/iptables -P FORWARD ACCEPT /sbin/iptables -t nat -P PREROUTING ACCEPT /sbin/iptables -t nat -P POSTROUTING ACCEPT /sbin/iptables -t nat -P OUTPUT ACCEPT # ALLOW ALL in PRIVATE NET /sbin/iptables -A INPUT -i lo -j ACCEPT /sbin/iptables -A INPUT -i eth1 -j ACCEPT # FTP /sbin/iptables -A INPUT -m limit --limit 100/s --limit-burst 100 -p tcp --dport 21 -j ACCEPT # SSH & TELNET /sbin/iptables -A INPUT -p tcp --dport 22 -j ACCEPT /sbin/iptables -A INPUT -p tcp --dport 25 -j ACCEPT /sbin/iptables -A INPUT -p tcp --dport 110 -j ACCEPT # VPN #/sbin/iptables -A INPUT -p tcp --dport 1723 -j ACCEPT #/sbin/iptables -A INPUT -p gre -j ACCEPT # WWW /sbin/iptables -A INPUT -m limit --limit 100/s --limit-burst 100 -p tcp --dport 80 -j ACCEPT # MYSQL # /sbin/iptables -A INPUT -p tcp --dport 3306 -j ACCEPT # SOCKS5 # /sbin/iptables -A INPUT -p tcp --dport 8039 -j ACCEPT # ICMP(PING) /sbin/iptables -A INPUT -p icmp --icmp-type echo-request -j REJECT /sbin/iptables -A INPUT -p icmp --icmp-type ! echo-request -j ACCEPT # NAT /sbin/iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -j MASQUERADE # DNAT SQL-SERVER & RADMIN to PRIVATE NET /sbin/iptables -A PREROUTING -t nat -p tcp -s ! 192.168.0.0/24 --dport 4899 -j DNAT --to 192.168.0.2:4899 /sbin/iptables -A PREROUTING -t nat -p tcp -s ! 192.168.0.0/24 --dport 5000 -j DNAT --to 192.168.0.3:4899 iptables -t nat -A PREROUTING -p tcp -m tcp -s 192.168.0.0/24 --dport 80 -j DNAT --to 192.168.0.1:3128 # DENY OTHERS /sbin/iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT /sbin/iptables -A INPUT -j MIRROR |
终于写完了，不容易，这17小时没白费！
