This facility is for centralizing log messages, not distributing them.
To avoid the loop, you will need to change:
local local
event event
| ,----. ,----. |
v v | | v v
,-------. | | ,-------.
|syslogd| | | |syslogd|
`-------' | | `-------'
| | `-----|-. | |
v `----------' `--' v
local local
log log
To:
local local
event event
| |
v v
,-------. ,-------.
| +--. | | ,--+ |
| | | | | | | |
| v | | | | v |
| o<-|--|<. ,>|--|->o |
| | | | | | | | | |
| v v | | | | v v |
`-------' | | `-------'
| | `-----|-. | |
v `----------' `--' v
local local
log log
You do this by making a disctintion based on whether the source is
local or remote and whether the destination is local or remote.
This is pretty much how you do mail/news gateways. 8-).
The NetBSD modified syslog might already do this (or if that's what
you are running, it might be your problem in the first place).
