Hello,

I have some trouble for understand how work rsyslog.
First what i have:
- One main rsyslog where all log are.
- One slave rsyslog who receive log from other machine and send all log to
man rsyslog

So at the slave I just forward log (I also save log but we don't care here)
and at the main rsyslog I want to keep the original Hostname and I can with
the line :
[code:1t1qx7sq]action (type="omfwd" Target="ip-man-syslog" Port="514"
Protocol="tcp")[/code:1t1qx7sq]
And i don't understand why that line work and when i receive log at the
main rsyslog at the field hostname I have the original Hostname (the
hostname of system who make the log) 
BUT when i keep the same line just using udp instead of tcp I have the
hostname of the slave rsyslog and not the original hostname.
Someone can tell me why ? 

I don't know if you really understand what I said, if you need more
information just ask me.
I know that it's not a problems because it's work like i want but I just
want to understand why.

Thanks,
Regards
