Phil,
Make sure you have ALLOW statements for both hosts in their respective
ldmd.conf files. You may have to use the IP address for twister2 instead
of the hostname until it's on DNS.

Hi Everyone,
We are getting ready to upgrade to a new machine and are in the process of
installing LDM 6.9.8 and have run into a couple of snags. I apologize if the
answers to these questions are somewhat elementary.
Right now we have the new machine (Twister2) as the downstream LDM to the
current machine(Twister); however, we can't seem to send anything to the new
machine.
Our setup is as follows:
Upstream LDMs for Twister
|
============ FIREWALL ============
|
|
Twister (twister.sbs.ohio-state.edu -- LDM v. 6.7.0)
|
|
Twister2 (128.146.191.17 -- twister2.sbs.ohio-state.edu not active on
DNS yet -- LDM v. 6.9.8)
I can't even find the LDM logs on Twister2 for some reason (ran
--enable-logging=local0 when configuring & ldmd.log is empty nor is there any
info in /var/log/messages), but in Twister's LDM logs I found that Twister2 can
connect, but we receive the following error (just once per ldmadmin start
occurrence):

I tried installing the LDM on my home computer and was able to send data from
Twister (home computer is obviously outside of the firewall)
Any help regarding the logging and/or connection is very much appreciated.
Thanks for any help in advance -- back to searching the support archives...
