Ubuntu Server上所提供的DNS Server套件是bind 接著我們開啟一個terminal 並輸入下列指令: 檢視原始檔複製到剪貼簿列印關於 1. sudo apt-get install bind9 sudo apt-get install bind9 接下來請提供具管理權限密碼並回答Y進行套件的安裝 安裝完成之後就要來設定了 首先編輯/etc/bind/named.conf.local 檢視原始檔複製到剪貼簿列印關於 1. sudo vim /etc/bind/named.conf.local sudo vim /etc/bind/named.conf.local 例如我們申請了一個網域叫作dadiling.com 且我們申請的真實IP是59.125.159.74 因此要新增底下的內容到named.conf.local中 檢視原始檔複製到剪貼簿列印關於 1. zone "dadiling.com" { 2. type master; 3. file "/etc/bind/dadiling.com.hosts"; 4. }; 5. zone "159.125.59.in-addr.arpa" { 6. type master; 7. file "/etc/bind/159.125.59.rev"; 8. }; zone "dadiling.com" { type master; file "/etc/bind/dadiling.com.hosts"; }; zone "159.125.59.in-addr.arpa" { type master; file "/etc/bind/159.125.59.rev"; }; 接下來要產生正向網域名稱檔案且新增一筆主機紀錄(mail.dadiling.com的真實IP對應到59.125.159.74) 請執行下列指令: 檢視原始檔複製到剪貼簿列印關於 1. sudo vim /etc/bind/dadiling.com.hosts sudo vim /etc/bind/dadiling.com.hosts 新增內容如下: 檢視原始檔複製到剪貼簿列印關於 1. $ttl 38400 2. dadiling.com. IN SOA mail1. dadiling.com. ( 3. 1255760316 4. 10800 5. 3600 6. 604800 7. 38400 ) 8. dadiling.com. IN NS mail1. 9. mail.dadiling.com. IN A 59.125.159.74 $ttl 38400 dadiling.com. IN SOA mail1.dadiling.com. ( 1255760316 10800 3600 604800 38400 ) dadiling.com. IN NS mail1. mail.dadiling.com. IN A 59.125.159.74 接下來要產生反向網域名稱檔案且新增一筆反向IP紀錄(真實IP 59.125.159.74對應到mail.dadiling.com) 請執行下列指令: 檢視原始檔複製到剪貼簿列印關於 1. sudo vim /etc/bind/159.125.59.rev sudo vim /etc/bind/159.125.59.rev 新增內容如下: 檢視原始檔複製到剪貼簿列印關於 1. $ttl 38400 2. 159.125.59.in-addr.arpa. IN SOA mail1.dadiling.com. ( 3. 1255760379 4. 10800 5. 3600 6. 604800 7. 38400 ) 8. 159.125.59.in-addr.arpa. IN NS mail1. 9. 74.159.125.59.in-addr.arpa. IN PTR mail. $ttl 38400 159.125.59.in-addr.arpa. IN SOA mail1.dadiling.com. ( 1255760379 10800 3600 604800 38400 ) 159.125.59.in-addr.arpa. IN NS mail1. 74.159.125.59.in-addr.arpa. IN PTR mail. 最後執行下列指令重新啟動bind DNS服務 檢視原始檔複製到剪貼簿列印關於 1. sudo /etc/init.d/bind9 restat sudo /etc/init.d/bind9 restat 就完成bind DNS Server的安裝了 參考資料�Ghttps://help.ubuntu.com/9.04/serverguide/C/dns-installation.html |

Ubuntu smtp验证配置 =========================================================== 作者: yeahokay(http://yeahokay.itpub.net) 发表于: 2008.04.08 17:25 分类: linux（Ubuntu） 出处: http://yeahokay.itpub.net/post/11939/459273 --------------------------------------------------------------- 在配置sendmail 的smpt验证时，碰到了不少麻烦事，最后总算搞定了。有时只是一些简单的操作，却是因为没有文档，导致配置工作的进展困难。这里记录下一些配置过程中忽略的小事情。 sudo apt-get install sendmail(其中已经包含了sendmail-bin) sudo apt-get install sasl2-bin 配置主要集中在sendmail.mc文件。 a)将MTA-v4的监听地址去掉，这样就可以监听所有地址。修改后如下： dnl DAEMON_OPTIONS(`Family=inet6, Name=MTA-v6, Port=smtp, Addr=::1')dnl DAEMON_OPTIONS(`Family=inet, Name=MTA-v4, Port=smtp')dnl dnl DAEMON_OPTIONS(`Family=inet6, Name=MSP-v6, Port=submission,Addr=::1')dnl DAEMON_OPTIONS(`Family=inet, Name=MSP-v4, Port=submission')dnl b)添加验证参数如下： TRUST_AUTH_MECH(`DIGEST-MD5 LOGIN PLAIN') define(`confAUTH_MECHANISMS',`DIGEST-MD5 LOGIN PLAIN') 直接添加到上面MTA的配置底下即可。 c)修改访问配置。使用了smtp验证后，就可以忽略access的配置。所以要将/etc/mail/access里面的配置内容清空。如果不清空，会出现不使用smpt验证也可以发送邮件的情况。 所有修改完毕后使用sendmailconfig命令，一路选择缺省即可。最后这个命令会reload sendmail。 4.验证安装和配置 启动sendmail后，telnet localhost 25，在出现的控制台，输入命令ehlo localhost 注意：localhost主要还是看/etc/hosts文件，一般（具体就不清楚，就我的机器是localhost：127.0.0.1，而具体做 mail服务的是ubuntu：192.168.20.6）是打上Aliases名称，如打上IP Address就是不认。 查看输出信息： 250-ENHANCEDSTATUSCODES 250-PIPELINING 250-EXPN 250-VERB 250-8BITMIME 250-SIZE 250-DSN 250-ETRN 250-AUTH DIGEST-MD5 LOGIN PLAIN 250-DELIVERBY 250 HELP 如果出现上面红色的字，表明已经可以了。 5.验证邮件发送。 配置好smtp验证后，在本地域的邮件发送还是可以不通过smtp验证直接发送。要验证smtp是否配置成功，必须发送到域外的邮箱如gmail邮箱。 一些容易碰到的问题： 1)sendmail配置好后，从别的机器telnet 25端口，连接被拒绝。 原因：这是由于缺省sendmail绑定到127.0.0.1的25端口，所以从别的机器telnet 192.168.0.230 25 并不能访问25端口。 解决：搜索sendmail.mc文件，将其中的 DAEMON_OPTIONS(`Family=inet, Name=MTA-v4, Port=smtp', Addr=127.0.0.1)dnl 修改为 DAEMON_OPTIONS(`Family=inet, Name=MTA-v4, Port=smtp', Addr=0.0.0.0)dnl 或者 DAEMON_OPTIONS(`Family=inet, Name=MTA-v4, Port=smtp')dnl 2)看到250-AUTH DIGEST-MD5 LOGIN PLAIN的标志，却还是不能使用smtp验证发送邮件 原因：可能未安装sasl2 解决办法：安装sasl2 sudo apt-get install sasl2-bin 安装完成后，在文件/etc/default/saslauthd文件中，找到START=no，修改为START=yes 修改完后/etc/init.d/saslauthd start 3)配置好后，可以使用smtp验证发送邮件，不使用smtp验证也能够发送邮件 原因：发送和接收邮件在域内，如果发送的邮件地址不在域内，则可能是 /etc/mail/access文件未清空。 解决：将 /etc/mail/access文件清空。 要注意的一点： 修改任何配置，需要重新启动sendmail，建议使用命令 sendmailconfig启动。 |
