This might be a better question for the Solaris forum, rather than the "Linux-Newbie" one....but a quick Google search turns up:

Quote:

In Solaris 8 and later, IP forwarding can be enabled or disabled on a per interface basis. For example, if there are 3 hme NIC cards namely hme0,hme1,hme2 then assume, we allow IP Forwarding only from hme0 and disable on hme1 and hme2 then the following will help:

# ndd -set /dev/ip hme0:ip_forwarding 1

And the error you're getting is telling as well...you say it's a "container server"...is this running under a Solaris 10 container? VMware? What platform (SPARC? x86?). DOES the /dev/ip device exist, and can you get out to the network.

Off to Solaris we go....

Are you using an exclusive or shared IP for that zone ?

i already given info that, it is a solaris 8 sparc machine.i can set ip_forwarding noemally if it is not container server.
# ndd -set /dev/ip ip_forwarding 1
but it throws error in container servers.
# ndd -set /dev/ip ip_forwarding 1
device name given is not a stream device (No such device or address)
or
# ndd -set /dev/ip ip_forwarding 1
open of /dev/ip failed: No such file or directory

Again, are you using a shared or exclusive IP ?
If not exclusive, you cannot set any networking flag with ndd on the non global zone.

it is exclusive ip not shared ip. Sun container can have 6 servers, 3 servers are solaris 10 with different ip and 3 servers are solaris 8 with different ip. but problem is still there.

Please post one of the Solaris 8 zones configuration. (/etc/zone/zonename.xml).

Hmm, I guess you mean Sun server have 6 containers.

malli42108 · 11-26-2009, 09:13 AM

sorry i mistaken, it's not exclusive ip , it is shared ip.
$ zoneadm list -vc
ID NAME STATUS PATH BRAND IP
1 dslam036-zone running / native shared

Below is your requirement.
vi /etc/zones/SUNWsolaris9.xml

<?xml version="1.0"?>



<!DOCTYPE zone PUBLIC "-//Sun Microsystems Inc//DTD Zones//EN" "file:///usr/shar
e/lib/xml/dtd/zonecfg.dtd.1">

<zone name="default" zonepath="" autoboot="false" brand="solaris8">
</zone>

Now please specify ,can i able to set ip_forwarding to these servers?

jlliagre · 11-26-2009, 09:19 AM

You didn't posted what I asked for: /etc/zones/dslam036-zone.xml (and please use code tags).

In any case, as you are using a shared IP, IP configuration is done in the global zone, not the solaris 8 zone.
