+Dell M1000e gRPC Proxy
+======================
+
+Cursedness level: 6.5/10 (regexp XML parsing, JSONP scraping, limited sessions).
+
+This is a small gRPC proxy to allow programmatic access to a Dell M1000e Chassis Management Controller. It's based on scraping the web interface, as the alternative (WSMAN) is even more ridiculous.
+
+Functionality
+-------------
+
+The only feature supported so far is getting information for an iDRAC KVM console. This can be used to run a iDRAC KVM proxy (to be implemented), or the original client.
+
+Usage
+-----
+
+ ./cmc-proxy -h
+
+Flags are self-explanatory. This is based on [hspki](https://code.hackerspace.pl/q3k/hspki), so you'll need to have compatible (dev) certs to run this. The proxy listens on gRPC and a status HTTP debug server.
+
+Example
+-------
+
+ $ grpc-dev -d '{"blade_num": 6}' cmc.q3k.svc.cluster.local:4200 proto.CMCProxy.GetKVMData
+ {
+ "arguments": [
+ "10.10.10.16:443",
+ "5901",
+ "oojo2obohhaWiu3A",
+ "1",
+ "0",
+ "3668",
+ "3669",
+ "511",
+ "5900",
+ "1",
+ "EN"
+ ]
+ }
