@whitequark Can't it log via #Syslog to another device on lan?

(I'm a complete PXE, NetBoot noob but interested )

nc -k -l -u 192.0.2.1 514 | awk 'BEGIN{nc="nc -q0 -u 198.51.100.1 514"}{print strftime("<13>%b %d %H:%M:%S bgw320-505 ATT-BGW320: ")$0 | nc; print $0}'

`nc` net cat

`-k` When a connection is completed, listen for another one.

`-l` Listen for an incoming connection rather than initiating a connection to a remote host.

`-u` Use UDP instead of TCP.

`192.0.2.1` & `514` IP & port to listen on.

`awk` Text manipulation tool

`BEGIN{...}` initialization block

`nc="..."` assign the net cat command and parameters to the `nc` variable.

`-q0` after EOF on stdin, wait the specified number of seconds and then quit.

`198.51.100.1` & `514` IP & port to send modified data to.

`print ... | nc` print the output into the command specified in the `nc` variable.

`strftime(...)` create a formatted time string

`<13>` Textual form of encoding of the `user` facility and `notice` level.

`%b` abbreviated month

`%d` day of month with space padding

`%H` hour of day in 0-23

`%M` minute of hour

`%S` second of minute

`bgw320-505` hostname

`ATT-BGW320:` message TAG

`$0` message CONTENT

` | nc` connect the output of the `print` into the input of the command defined in the `nc` variable.

`print $0` print the line to STDOUT (separate from the `nc` command) used to help debug things.

Two standard Unix commands; #nc and #awk, put together creatively allow creating a #SYSLOG relay.
