    aix防火墻怎么樣設(shè)置

    時間: 林輝766 分享

      aix防火墻對我們來說是非常重要的,你會不會設(shè)置呢?下面由學(xué)習(xí)啦小編給你做出詳細(xì)的aix防火墻設(shè)置方法介紹!希望對你有幫助!

      aix防火墻設(shè)置方法一:

      1. 使用smit命令打開圖形化窗口進(jìn)行系統(tǒng)配置

      2. 選擇以下子項開啟或關(guān)閉防火墻Communications Applications and Services->Tcp IP->Configure Ip Security(IPv4)->Start/Stop IP Security->Start IP Security

      3. 也可以使用以下子項對防火墻進(jìn)行配置Communications Applications and Services->Tcp IP->Configure Ip Security(IPv4)->Start/Stop IP Security->Advantanced IP Security Configuration

      aix防火墻設(shè)置方法二:

      IPTRACE 可以看見防火墻上的網(wǎng)絡(luò)通信狀況,典型的命令格式如下: iptrace -d OUTSIDE_IP_ADDRESS -b /tmp/trace.out 其中 -d 參數(shù)后跟目標(biāo)地址

      -b 代表雙向通信 要想看見網(wǎng)絡(luò)的通信狀況或發(fā)現(xiàn)故障的原因

      做如下幾步:

      1. 運(yùn)行 iptrace 命令 iptrace -d OUTSIDE_IP_ADDRESS -b /tmp/trace.out

      2. 當(dāng)故障發(fā)生時,殺掉 iptrace 進(jìn)程。 用 "ps -ef|grep iptrace"命令來獲得iptrace 的進(jìn)程號。 然后用 "kill -9 PROCESS_ID" 命令來停止trace。

      相關(guān)閱讀:

      aix網(wǎng)關(guān)查看方法

      查看當(dāng)前的默認(rèn)網(wǎng)關(guān)

      netstat -rn

      會看到有多條的default.

      如果用route命令(或smitty route)去刪除,下次重啟后,又會回來;所以要從ODM里刪除。

      2.查看ODM信息

      # lsattr -El inet0

      authm 65536 Authentication Methods True

      bootup_option no Use BSD-style Network Configuration True

      gateway Gateway True

      hostname appserv1 Host Name True

      rout6 IPv6 Route True

      route net,-hopcount,0,,0,192.111.10.251 Route True

      route net,-hopcount,0,,0,192.110.9.63 Route True

      route net,-hopcount,0,,0,192.111.11.251 Route True

      route net,-hopcount,0,,0,192.110.9.251 Route True

      # odmget -q "name=inet0" CuAt

      CuAt:

      name = "inet0"

      attribute = "hostname"

      value = "host1"

      type = "R"

      generic = "DU"

      rep = "s"

      nls_index = 24

      CuAt:

      name = "inet0"

      attribute = "route"

      value = "net,-hopcount,0,,0,192.111.11.251"

      type = "R"

      generic = "DU"

      rep = "s"

      nls_index = 0

      CuAt:

      name = "inet0"

      attribute = "route"

      value = "net,-hopcount,0,,0,192.111.10.251"

      type = "R"

      generic = "DU"

      rep = "s"

      nls_index = 0

      CuAt:

      name = "inet0"

      attribute = "route"

      value = "net,-hopcount,0,,0,192.110.9.251"

      type = "R"

      generic = "DU"

      rep = "s"

      nls_index = 0

      CuAt:

      name = "inet0"

      attribute = "route"

      value = "net,-hopcount,0,,0,192.110.9.63"

      type = "R"

      generic = "DU"

      rep = "s"

      nls_index = 0

      其中正確的應(yīng)是192.110.9.63,其它都是多余的。

      3.逐條刪除沒用的默認(rèn)路由

      # chdev -l inet0 -a delroute="net,-hopcount,0,,0,192.111.11.251"

      Method error (/usr/lib/methods/chginet):

      0514-068 Cause not known.

      0821-279 writing to routing socket: The process does not exist.

      0821-103 : The command /usr/sbin/route delete -net -hopcount 0 0 192.111.11.251 failed.

      ###刪除其它(略)###

      出現(xiàn)上面的報錯信息,應(yīng)該是AIX5.3的“誤報”(至少在5300-08-01上是這樣,AIX6不會)可以不用理會。

      4.確認(rèn)生效

      # lsattr -El inet0

      authm 65536 Authentication Methods True

      bootup_option no Use BSD-style Network Configuration True

      gateway Gateway True

      hostname appserv1 Host Name True

      rout6 IPv6 Route True

      route net,-hopcount,0,,0,192.110.9.63 Route True

      # odmget -q "name=inet0" CuAt

      CuAt:

      name = "inet0"

      attribute = "hostname"

      value = "appserv1"

      type = "R"

      generic = "DU"

      rep = "s"

      nls_index = 24

      CuAt:

      name = "inet0"

      attribute = "route"

      value = "net,-hopcount,0,,0,192.110.9.63"

      type = "R"

      generic = "DU"

      rep = "s"

      nls_index = 0

      # netstat -rn
