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(xiàng)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(xiàng)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:

  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
