aix防火墻怎么樣設(shè)置
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 進程。 用 "ps -ef|grep iptrace"命令來獲得iptrace 的進程號。 然后用 "kill -9 PROCESS_ID" 命令來停止trace。

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
