配置 dns服务器 碰到的问题

pldsec

请大家看看我的配置，然后帮忙提提意见：
我的域名服务器的反向解析文件内容:
TTL
　　@ IN SOA ns.pldsec.com. root.pldsec.com.(
　　　　19997022700;serial
　　　　28800; refresh
　　　　14400; retry
　　　　3600000; expire
　　@ IN NS ns.pldsec.com.
　　99 IN PRT mail.pldsec.com.
　　99 IN PRT www.pldsec.com.
域名服务器的正向解析文件内容:
#文件 pldsec.com.hosts
$ TTL 86400
　　
　　@ IN SOA ns.pldsec.com. root.pldsec.com.
　　 (42; serial (d.adams)
　　 3H; refresh
　　 15M; retry
　　 1w; expiry
1D;minimum
　　@ IN NS ns.pldsec.com.
　　
@ IN A 192.168.1.99
　　
　　www IN A 192.168.1.99
mail IN A 192.168.1.99
　　
@ IN MX 10 mail.pldsec.com.

运行命令 nslookup 出现的错误提示为:
[root@server etc]# nslookup
Note: nslookup is deprecated and may be removed from future releases.
Consider using the `dig' or `host' programs instead. Run nslookup with
the `-sil[ent]' option to prevent this message from appearing.
