自从Windows 2000以来,MS一直在推荐Kerberos,所以现在终于可以开始使用该程序了.
很多,非常感谢Squid邮件列表中的Markus Moeller帮助实现这一目标.
在Windows方面,Windows XP和Windows 2007已针对Windows 2008和Windows XP针对Windows 2003进行了测试.
请注意,几乎每个步骤都需要前面的步骤.
如果您遇到问题,DNS始终是第一个看的地方.两台Windows机器都应该能够通过名称ping Linux服务器(反之亦然),您可能需要运行ipconfig / flushdns.重新启动也可能有所帮助,如果你想确定没有任何问题.
域信息
> Windows域名:dom.local
>域服务器:server.dom.local,172.17.3.11
> CentOS squid服务器:centos.dom.local,172.17.3.10
域服务器设置
>在DNS配置中创建dom.local反向区域.
>为centos.dom.local创建指向172.17.3.10的静态(‘A’)记录,当询问是否要设置反向PTR时选择是.
Windows 2008
对于Windows 2008服务器,您需要安装Hotfix 951191.
Linux安装程序
小包装
安装包
$yum install -y cyrus-sasl-gssapi cvs autoconf automake openldap openldap-devel krb5-workstation krb5-devel gcc-c++
安装msktutil.您需要在构建之前对其进行修补.
$wget http://download.systemimager.org/~finley/msktutil/msktutil_0.3.16.orig.tar.gz $wget http://download.systemimager.org/~finley/msktutil/msktutil_0.3.16-7.diff.gz $gunzip msktutil_0.3.16-7.diff.gz $tar zxf msktutil_0.3.16.orig.tar.gz $cd msktutil-0.3.16 $patch < ../msktutil_0.3.16-7.diff $./configure && make && make install
编译最新的squid_kerb_ldap.
$cvs -z3 -d:pserver:anonymous@squidkerbauth.cvs.sourceforge.net:/cvsroot/squidkerbauth co -P squid_kerb_ldap $cd squid_kerb_ldap $./configure && make
DNS
使用system-config-network配置域控制器的DNS点,将主机名设置为centos.dom.local.
重启
检查反向DNS工作正常:
$dig -x 172.17.3.10
你应该在答案部分获得centos.dom.local.如果你不这样做,那就没有意义了.如果没有正确配置DNS,Kerberos身份验证将无法运行.
Kerberos的
你的krb.conf应该是这样的:
[logging] default = FILE:/var/log/krb5libs.log kdc = FILE:/var/log/krb5kdc.log admin_server = FILE:/var/log/kadmind.log [libdefaults] default_realm = DOM.LOCAL dns_lookup_realm = false dns_lookup_kdc = false ticket_lifetime = 24h # For Windows XP: default_tgs_enctypes = rc4-hmac des-cbc-crc des-cbc-md5 default_tkt_enctypes = rc4-hmac des-cbc-crc des-cbc-md5 permitted_enctypes = rc4-hmac des-cbc-crc des-cbc-md5 # For Windows 2007: # default_tgs_enctypes = aes256-cts-hmac-sha1-96 rc4-hmac des-cbc-crc des-cbc-md5 # default_tkt_enctypes = aes256-cts-hmac-sha1-96 rc4-hmac des-cbc-crc des-cbc-md5 # permitted_enctypes = aes256-cts-hmac-sha1-96 rc4-hmac des-cbc-crc des-cbc-md5 forwardable = yes [realms] DOM.LOCAL = { kdc = 172.17.3.11:88 admin_server = 172.17.3.11:7491 default_domain = dom.local } [domain_realm] .dom.local = DOM.LOCAL dom.local = DOM.LOCAL [appdefaults] pam = { debug = false ticket_lifetime = 36000 renew_lifetime = 36000 forwardable = true krb4_convert = false }
创建密钥表:
$kinit administrator $msktutil -c -b "CN=COMPUTERS" -s HTTP/centos.dom.local -h centos.dom.local -k /etc/HTTP.keytab --computer-name centos-http --upn HTTP/centos.dom.local --server server.dom.local --verbose
对于Windows 2008,您需要将–enctypes 28添加到msktutil命令.
乌贼
安装鱿鱼:
$wget http://www.squid-cache.org/Versions/v3/3.0/squid-3.0.STABLE18.tar.gz $tar zxvf squid-3.0.STABLE18.tar.gz $cd squid-3.0.STABLE18 $./configure --enable-negotiate-auth-helpers=squid_kerb_auth --enable-stacktraces --prefix=/opt/squid-3.0 $make $make install $cp helpers/negotiate_auth/squid_kerb_auth/squid_kerb_auth /opt/squid-3.0/sbin/ $cp ~/squid_kerb_ldap/squid_kerb_ldap /opt/squid-3.0/sbin/ $cd /opt/squid-3.0/ $mv etc/squid.conf etc/squid.conf.ORIG
在squid.conf中设置适当的参数:
auth_param negotiate program /opt/squid-3.0/sbin/squid_kerb_auth -d -s HTTP/centos.dom.local auth_param negotiate children 10 auth_param negotiate keep_alive o external_acl_type SQUID_KERB_LDAP ttl=3600 negative_ttl=3600 %LOGIN /opt/squid-3.0/sbin/squid_kerb_ldap -d -g SQUID_USERS acl AUTHENTICATED proxy_auth required acl LDAP_GROUP_CHECK external SQUID_KERB_LDAP acl localnet src 172.17.3.0/24 # RFC1918 possible internal network #http_access allow localnet #http_access allow AUTHENTICATED http_access allow LDAP_GROUP_CHECK cache_dir ufs /var/cache/squid-3.0 100 16 256 access_log /var/log/squid-3.0/access.log squid cache_log /var/log/squid-3.0/cache.log cache_store_log /var/log/squid-3.0/store.log pid_filename /var/run/squid-3.0.pid cache_effective_user squid cache_effective_group squid coredump_dir /var/cache/squid-3.0
设置用户和目录:
$chown -R squid:squid /opt/squid-3.0/ $mkdir /var/cache/squid-3.0 $chown -R squid:squid /var/cache/ $mkdir /var/log/squid-3.0 $chown -R squid:squid /var/log/squid-3.0/ $chown squid:squid /etc/HTTP.keytab
创建缓存:
$/opt/squid-3.0/sbin/squid -z
初始化脚本
现在这很重要:Squid需要一些环境变量设置才能正常运行.执行此操作的最佳方法是使用init脚本.这是一个略有编辑的CentOS:
#!/bin/bash # squid This shell script takes care of starting and stopping # Squid Internet Object Cache # # chkconfig: - 90 25 # description: Squid - Internet Object Cache. Internet object caching is \ # a way to store requested Internet objects (i.e.,data available \ # via the HTTP,FTP,and gopher protocols) on a system closer to the \ # requesting site than to the source.

这些是重要的路线:
KRB5_KTNAME=/etc/HTTP.keytab export KRB5_KTNAME
客户端机器
使用端口3128将代理设置为服务器centos.dom.local.使用完全限定的域名而不是IP地址非常重要.
