Can't assign requested address (errno:227)

[Mohd Azahari]

Hi,

I have installed Oracle Reports Server on HPUX itanium 64 bit. But now I could not bring up the report server because of the error above. Checking the default multicast ip below gives me the error. How can I configure multicast?

$ /opt/java6/bin/IA64W/java -jar ./stage/Multicast/mcastserver.jar -ipaddress 228.5.6.7 -port 999 -delay 1000 -verbose -message "test"
Server running with multicast address [228.5.6.7:999]

Using Setings:
Multicast Address : 228.5.6.7
Multicast Port : 999
Message :test
Max Delay :1000
Random Delay :false
Verbose :true

Error: Can't assign requested address (errno:227)
java.net.SocketException: Can't assign requested address (errno:227)

Hello,

a) mcastserver.jar is a Multicast Checker.
It simply tests the setup.

b) In its simplest form, multicast address
is set up this way:

# route add 228.5.6.7 192.168.5.20 0

To add it permanently, the following lines
need to be added into
/etc/rc.config.d/netconf:

ROUTE_DESTINATION[X]=â 228.5.6.7â
ROUTE_GATEWAY[X]=â 192.168.5.20â
ROUTE_COUNT[X]=â 0â

X is an unused positive integer in network
setup.

In this example, I assume your local interface (lan3, lan4, or aggregate lan900)
has IP address 192.168.5.20.

Cheers,

Hi,

thanx for replying but I got the following error:

# route add 228.5.6.7 192.168.5.20 0
add host 228.5.6.7: gateway 192.168.5.20: Network is unreachable

Here's netstat -rn:

Hello Mohd,

I think you misunderstood my example because
you did not provide your real IP addresses
in the original message.

Your IP address is different from my example,
so this is what should work:

# route add 228.5.6.7 10.66.130.14 0

Cheers,
