20030915:SuomiNet LDM IP Deny



Hi Maggie,

Our receipt of data has gone un-interrupted.....

Do we know WHO is not getting data, is this widespread or sporadic.

My obvious questions are:

Have the downstream sites not getting data reconfigured their machines in
any way..i.e. DNS server IP etc..I suspect the issue is not with ldm1, but
with the downstream site(s)...barring any mods to suomildm1.

What are the error statements in the downstream sites logs?

This IP is unresolvable so must be in the hosts_allow directory implicitly
for it to work..

Only if you removed DNS capabilities from suomildm1..
