DHCPStatus is a query tool for browsing information stored in DHCPD's configuration and leases files. It has both a Web-based, and a command-line interface. It correlates the subnet details that you configure in the conf file, with the lease records that DHCPD maintains in its lease file. You can thus obtain an overall picture of your DHCP environment, as well as view details of individual leases for each IP.
dlkern downloads the current stable/beta/prepatch Linux kernel and its signature, and verifies the signature via GnuPG.pm. Versions are specified on the command line as -s (stable), -b (beta), or -p (pre-patch) (all 3 may be specified at once). Downloads are done via ncftpget, wget, or Net::FTP. It allows specification of 2-letter country code for the kernel mirror system, and selection of compression format (.gz/.bz2).
