Provided both Debian and Ubuntu clients are in the same network segment, have a look at the firewall configuration on the Ubuntu systems. On the other hand, what do you exactly mean by "login"? Something like 'ssh someu...@server.example.com' from the clients? (I doubt any kind of local firewall would prevent outgoing ssh connections). > We are new to networking in LINUX.

Well, IPv4 is easierly understood, so it make sense take away as much problem sources as possible. How did you disable IPv6? How did you know IPv6 was in fact disabled? PS: You know that NIS is an unsecure protocol only to be used if you are absolutly convinced you are tightly controlling all the clients that can attach to the network, do you? The roughly equivalent to an AD-based Windows network, security and functionality-wise, would be LDAP+Kerberos+NFSv4 (plus a whole lot of other "minor" services like DNS, DHCP, automounters, cups, puppet, a local CA, etc.). -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
