aix 如何设置系统网关

摘抄自smallmiao的帖子，看着比较靠谱，你试试

查看当前的默认网关

netstat -rn

会看到有多条的default.

如果用route命令（或smitty route)去删除，下次重启后，又会回来；所以要从ODM里删除。

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

其中正确的应是192.110.9.63，其它都是多余的。

3.逐条删除没用的默认路由

# 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.

###删除其它(略)###

出现上面的报错信息，应该是AIX5.3的“误报”（至少在5300-08-01上是这样，AIX6不会）可以不用理会。

4.确认生效

# 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
