Ok. Thank you for message. I hadn't realized that ldpd wasn't ready for users. I'd like to help out, but I don't have a lot of experience in C, or the linux network architecture. If there is a way I can help, please let me know. For now, I'll keep sending bug reports :) The thing is that I kind of relied on ldpd working so I can set up experiments for my graduation diploma. I'd like to ask you at what stage has the development of ldp arrived? Is it mostly done, with bugs to clear? Or is it somewhere in the middle of development? If it's the first case, I'd like to help you (as best I can) to isolate and correct any bugs. If there's a lot of work to be done, I'm sorry, I'd like to help, but I'm afraid I'm pressed by the lack of time. Are you close to releasing a new version of ldp? (Could it be done in less than 1.5 months?) If yes, I'm eager to help. If not, then the result could arrive to late to help me. I hope my reply hasn't brought you down. I'll keep trying to use ldpd (I'm not out of ideas yet), but I'd like to ask you two more questions: 1. Has this version of ldpd worked on a given test-bed? (Has it done what it was supposed to do?) 2. Do you have some more elaborate configuration files for ldpd for the test-bed it worked on? (So that at least, I have somewhere to start from).
