Since the very beginning midas had the problem that the last event of a run was
sometimes missing in the data. While for most experiments this is not an issue,
it starts to hurt on experiments using event building (front-end 1 and front-end

Running MIDAS at CERN is proving more challenging than I expected. The network environement is not
as benign as I am used to (i.e. at TRIUMF) and our machines are being constantly probed by something/
somebody.

I am in favor of tcp_wrappers.
tcp_wrappers is well understood.

08 Jun 2007, Stefan Ritt, Suggestion, RFC- ACLs for midas rpc, mserver, mhttpd access

First I have a general question: mserver is started through xinetd, and xinetd has
the options "only_from" and "no_access". This is equivalent to the tcp_wrapper
functionality. Why not using this? It's possible without changing anything in midas.

can be re-used for many experiments. The user only needs to provide an script "daq_env.sh" as the following containing the settings for the experiment

From "history" pages, the "create elog" button stopped working - it takes us to the elog entry form, but
then, the "submit" button does not create any elog entries, instead dumps us into an invalid history
