Problem description:I can't login to my machine with NIS, it gives me "unable to help authenticate" again - for some reason I can't login as kernel either, but I can ssh into Box as root where I find : "No such map passwd.byname. Reason: NIS internal error"I've tried a lot of things, thought about it, and then looked through all the forum posts I could find, but I'm still having trouble logging in.

Hello,Have you checked if your NIS is configured correctly? ssh to the device as root and check if ypbind is running /etc/sysconfig/network (the value of the NISDOMAIN variable), the output of the domain name command (should be the same as NISDOMAIN) /etc/yp.conf (again, the same domain value and start the appropriate server). Try the commandypwhat (you really depend on the server from yp.conf, surely the server is running ypserv?). Check these firewall settings on the client and computer connected to the Internet (try to disable them for a reasonable amount of time).it's hard to tell what's wrong, i want to try the above and let me see the details.
