Nancy,

The $ip_addr setting should be configured _only_ if you are trying to
run the LDM on a single interface on a machine that has multiple Ethernet
interfaces:

<from ldmadmin-pl.conf>

"
# The IP address of the network interface to be used by the LDM server.  If not
# set, then the LDM server will use all available network interfaces.
"

>Is that supposed to be Godzilla's IP address?

If you are trying to limit the LDM to working on a single interface in
a multi-interface system, this would be set to the IP address of the
interface you want the LDM to use.  If you only have a single interface
in your machine, it would be best to simply comment out this setting.

It is set to the IP address of a interface on your machine when there
are multiple interfaces.  You can see all of the interfaces that exist
on your system by running:

/sbin/ifconfig -a

Look at the listings marked as ethx.  Here is an example on a system
running Fedora Core 3 and that has one interface:

~: /sbin/ifconfig -a
eth0      Link encap:Ethernet  HWaddr 00:10:5A:11:50:43
          inet addr:128.117.140.169  Bcast:128.117.140.255  Mask:255.255.255.0
          inet6 addr: fe80::210:5aff:fe11:5043/64 Scope:Link

          RX packets:0 errors:0 dropped:0 overruns:0 frame:0

          collisions:0 txqueuelen:0
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

In this example, the 'eth0' entry shows the IP address as 128.117.140.169.

Here is a similar example on a 64-bit system running Fedora Core 3
64-bit that has multiple interfaces:

[ldm@uni1 ~]$ /sbin/ifconfig -a
eth0      Link encap:Ethernet  HWaddr 00:09:3D:00:95:66
          inet addr:128.117.140.111  Bcast:128.117.140.255  Mask:255.255.255.0

          RX packets:0 errors:0 dropped:0 overruns:0 frame:0

          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)
          Interrupt:185

          inet addr:127.0.0.1  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:10842 errors:0 dropped:0 overruns:0 frame:0
          TX packets:10842 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:1077271 (1.0 MiB)  TX bytes:1077271 (1.0 MiB)

          inet addr:128.117.140.3  Mask:255.255.255.255
          UP LOOPBACK RUNNING  MTU:16436  Metric:1

tunl0     Link encap:IPIP Tunnel  HWaddr
          inet addr:192.52.106.21  Mask:255.255.255.255
          UP RUNNING NOARP  MTU:1480  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0

          collisions:0 txqueuelen:0
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

In this example, eth0's IP address is 128.117.140.111, and eth1's IP
address is not set.

>Then it keeps timing out without making a connection.

If the address you sent along is not the IP address of an interface
on your system, then the LDM will continually timeout since it will
not be able to open the interace.

RECOMMENDATION:  comment out the $ip_addr entry in your ldmadmin-pl.conf
file and stop and restart your LDM.

Cheers,

Tom
