[syslog-ng] syslog-ng to receive remote messages from sysklogd and rsyslog?

[Balazs Scheidler]

Yes, both rsyslog and sysklogd implement syslog protocol just like
syslog-ng.

Sysklogd only supports UDP, which is lossy.

Rsyslog also supports TCP but the version you are referencing is ancient.

Syslog-ng keeps its opened connections alive when reloaded, with restarts
those connections are closed and then reopened.

Inflight messages can get lost, which the client assumes were sent and the
server didn't receive them. To overcome this limitation something like rltp
or relp is needed.
