RPC means...?

Almost all of my code resides on world of Linux back-end.
Occasionally I need to create a user interface - which I've done lately in C#.

The back-end Linux code is almost always Perl, but will interact with a variety of 3rd party programs.

So (for a trivial example), I need to create a C# interface that queries that status of a back-end production, and this status is an aggregation of Linux stuff (load average, SGE queue size, plus some information in some log tables currently in Postgresql).

My 1st instinct is to create a Perl program on the Linux size, and have it produce some clearly defined text strings on output. This is then callable from any command line.

I would then need to hand this data off to the C# side, since it would be invloked by a user pressing a button, querying the status of the system. I would want the C# to format and present it, since I hate web presentation/interaction and these are all in-house windows clients.

Based on what you said, it seem a CGI interface a decent answer.

Hm - what about SOAP?

Is this something that can be done using the "pretend I'm a web client" APIs in C# on the client side, and some CGI scripts on the server using Apache and SSL? It's easy to use basic authentication, and SSL makes that snooper-proof.

There are a bunch of approaches the the latter problem, depending on those pesky details.

Just use a simple POST/response interface, and you'll be all happy and stuff. Regards, -scott anderson "Welcome to Rivendell, Mr. Anderson..."

Note, SOAP used to stand for Simple Object Access Protocol. It now stands for nothing because people couldn't stand the irony, seeing as how it isn't simple and no objects are involved.
