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...
