Is this one working on the testnet? I am not sure.

admin.addPeer("enode://a623eadd411ab6d612e091716706a22de86a9d01e932bcd170463e46920073be04e0c9263a3c2720bb18a446d1a95d39e9a90f903e954514ea530296a462d637@2.105.196.29:39340"")

my testnode address: "0xc3807abee52c39b9a3bdd682602eb5f36c5adee8"

However, this IP Address is unfortunately not static. But, I'll check it out now and then; correcting the node.
