I'm quite a beginner with administration, and I've not had problems with my VPS before. But after having trouble with an upstart-bug, which I was able to solve, I had to reboot the system, and since then I cannot open any ports > 1000 any more, even with root.
I only need those for redis and mongodb, and only so my server can communicate with them locally (no outside listening). I get this error for mongodb, for example:
ERROR: listen(): bind() failed errno:99 Cannot assign requested address for socket: 127.0.0.1:27017
I haven't changed anything in the configs at all, merely installed the upstart patch. I don't even know how to find the actual problem.
Anyone can help me? I will provide additional logs or whatever if someone told me which.
