FollowMeIP is a small client that allows you to retrieve the IP address of your machine over the Web. It works by periodically sending your IP address to the FollowMeIP server, from where you can retrieve it using a password. It is ideal for people that are running servers on dynamic IP connections, or are away from home and want to access their machines.
Dnsupdate creates DNS tables from a hosts file and the dnsupdate configuration file. It can be used to update or maintain the DNS tables. Hosts and aliases are added dynamically. Supports BIND 8 or higher. It has been tested on Sparc Solaris 8 and i386 FreeBSD 4.2 platforms. And should be easily portable to other platforms.
adlook (Address Lookup tool) is a multi-threaded host name and technical contact lookup tool. It accepts a list of IP addresses from the command line, from a data file, or from stdin, and outputs the hostname and technical contact for each address. Although it is written in Python, for the time being it runs only on UNIX systems. Python must have been compiled with threads enabled to run adlook.
Zoned manages BerkeleyDB zone databases using the BDB Replication Base API. It manages all node communication and eases the difficulties that BerkeleyDB replication imposes (such as making sure that all zone changes go straight to the master node for transaction processing). It requires the BIND9 DLZ BDBHPT driver.
radns is a small, portable client-side implementation of the RDNSS option in IPv6 Router Advertisements (RFC 5006) that is used to get the address of a resolving DNS server. It listens for Router Advertisements with the Recursive DNS Server (RDNSS) option and stores the addresses in a file following the same syntax as resolv.conf. It optionally calls a script to handle, for instance, DHCP clients that compete for ownership of /etc/resolv.conf or to set the DNS server on systems that don't use resolv.conf at all. It can be easily integrated with the resolvconf(8) program.
dnscacheaudit is a simple Perl utility to audit entries in the BIND cache. At the end of each run, it creates a PDF report showing the number of domains in the BIND cache that have a different IP address in the cache than the reference servers. This utility is inspired by the CacheAudit utility by Jose Avila.
CD Linux Server is an embedded Linux system on a bootable live CD. It can be used to set up mail, Web, file, FTP, proxy, DHCP, DNS, MySQL, LDAP, and other services very quickly. The mail server includes antivirus, antispam, and mail recorder features. It can be used for free for up to 10 accounts, while the advanced version is licensed for an unlimited number of users. There is not any restriction against the time.
