Even if you think things are good, it doesn’t necessarily mean that everything is working as well as it should.Most of you won’t be running Windows 2003 anymore, but if you are, this link may be of interest: DHCP setup primarily is the place to start with this, it is often overlooked that there needs to be a username entered into DHCP to allow for these Dynamic Updates to take place.Update: added a new post on configuring Solaris, link below.Motivation In today's dynamic R&D network environments, it's not easy to keep the DNS records up-to-date: hosts are reinstalled/renamed/added frequently, virtual machines are so easy to deploy and destroy, DHCP allocates different IPs..Besides from running my own separate DNS server, what's a Linux Sys Admin to do?The I'm willing to bet that the System Administrator running your Windows DHCP server is requiring secure Dynamic DNS updates.
I have an odd DNS issue that only sometimes presents itself.
I have several Linux machines, running Ubuntu (10.10, 11.10, 12.04). Sometimes, however, the system gets an IP address from DHCP, but fails to update the DNS server with it's hostname and IP.
All of the systems are using DHCP with default settings. The Sys Admin who runs the DNS servers (Windows Server something) says that everything is fine, and any issues I'm having must be my fault. This problem today prevents my team from being able to access our subversion server, and the (Linux) workstations can't connect to LDAP for user authentication. However, the LDAP and Subversion servers are up with valid IPs, and can access other network resources and the Internet, but don't have an associated DNS entry.
IRLP has no control over which pre-access code some nodes may choose to use to connect and disconnect. The standard codes are just the 4-digit node number to call a node, and "73" to disconnect.
Some owners/clubs may charge a fee for codes to help support their club and to offset the cost of setting up and running the IRLP node.
