Losing default gateway on an F150 (AIX) 1

[1500wing]

Whenever I boot an F150, I lose the default gateway, thereby having to manually enter it in via smit (or the CLI). Any reasons why this would do a disappearing act? I am running AIX 5.1, level 3.

Thanks

Hi,

Please post the result of the following for ALL interfaces you have :

mktcpip -S enX

The posting of both en0 and en1 is as follows, chronologically:

mktcpip -S en0
#host:addr:mask:_rawname:nameserv:domain:gateway:cost:activedgd:type:start
ppp:192.168.200.245:255.255.255.0:en0:192.168.200.1:wdpi.com:192.168.200.100:0:no:N/A:no

mktcpip -S en1
#host:addr:mask:_rawname:nameserv:domain:gateway:cost:activedgd:type:start
ppp:192.168.200.245:255.255.255.0:en1:192.168.200.1:wdpi.com:192.168.200.100:0:no:N/A:no

I don't believe DHCP is enabled on this box.

Thanks gang!

Your hostname is realy ppp or do you have ppp protocol defined on the host ?

Th hostname is really ppp. It was named that long before I showed on the scene. It may be a good isea to rename it, just so there is no confusion with any protocols...

Can you please post the IP part of the /etc/hosts ?

Thanks

Can you do

odmget CuAt|grep -ip route

You should get an output like

CuAt:
name = "inet0"
attribute = "route"
value = "net,-hopcount,0,,0,192.168.5.1"
type = "R"
generic = "DU"
rep = "s"
nls_index = 0

Check that the value is like above, except for the your default gateway replacing the 192.168.5.1

Note: There should be exactly 1 stanza that meets this criteria, if you have more than 1 , that could be a problem

Hey gang,

The IP of /etc/hosts is as follows:

127.0.0.1 loopback localhost
192.168.200.245 ratbert

The odm database shows three stanza's for the ip route. This output is as follows:

CuAt:
name = "inet0"
attribute = "route"
value = "net,-hopcount,0,,0,192.168.200.100"
type = "R"
generic = "DU"
rep = "s"
nls_index = 0

CuAt:
name = "inet0"
attribute = "route"
value = "net,-hopcount,0,,0,192.168.200.1"
type = "R"
generic = "DU"
rep = "s"
nls_index = 0

CuAt:
name = "inet0"
attribute = "route"
value = "net,-hopcount,0,,0,192.168.200.245"
type = "R"
generic = "DU"
rep = "s"
nls_index = 0

That doesn't look right to me. I think that the ODM duplications may will be the issue here. I would suggest deleting the 3 route entries and then going into smit and redefining your default gateway afresh.

odmdelete -o CuAt -q "name=inet0 and attribute=route"

should get rid of these 3 entries for you. If it has worked, you should get a message

0518-307 odmdelete: 3 objects deleted.

If you now do an odmget CuAt|grep -ip route , you should find no entries.

Now do a

route delete default

to delete the current active default gateway. Make sure that you are logged in from another machine on the same network so that you don't lose your connection to the box.

Now just re-add the correct default gateway by doing smit tcpip -> minimum configuration and startup -> en0 and adding the desired default gateway address in

Now if you do an

odmget CuAt|grep -ip route

you should just find one correct entry

[1500wing]

Well my friend,

I gave this a try and I still lose the default gateway after each re-boot. However, there is only one entry within the ODM for the gateway now, so that is much cleaner. I think this box has a mind of its own...

 

[MoshiachNow]

HI,

How about removing the ent0 + en0 completely and reconfiguring them ?
This could help.
Can use the following sequence:

stopsrc -g tcpip
stopsrc -g nfs
chdev -l en0 -a state='down'
rmdev -dl en0
rmdev -dl ent0

Good news mano...it worked! I had deleted previously, albeit with multiple routes within the ODM. She reboots back up with logins, telnets, etc at a snap of a finger.

Thanks much levw!
