as brought up today, it is definitely worth talking about how this
should be done, but if you follow the advice you should implement your own
heartbeat. The biggest issue I can see in your case is that you do not have
control over the remote node nor the protocol.

Security through obscurity? I can see where you're going with this, but public keys are not secure and relying on them being secret makes the design a bit flaky. It's only a matter of time once a target is established. Public keys are the least of worries.

To build 0MQ you need gcc, make, gcc-c++, libstdc++-devel on a RHEL system.
However, once you've built the package it can be installed without gcc. If you
are on RHEL then simply build an RPM with the latest spec file and you should
be just fine.

MinRK has a valid point. Is it just too much work and/or expensive to put this
on sockets and not the context? It makes 100% sense to put this in individual
sockets versus the entire con
hat term is more
encompassing. I believe "devices" should be kept with subcategories including
"proxy" and "gateway". It would definitely make sense with REST anyway.

If it fails to build you are not installing it, but trying to build from
source? If so, try the latest RHEL5. 5.3 is quite old.
