DLC (Dynamically Loadable Classes) is a compact utility that allows loading of shared libraries with C++ classes at runtime in an elegant and convenient way. It has been tested on a Linux platform with gcc 2.95.2, but should work on other ELF platforms as well. A C++ compiler with RTTI support is required.
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).
Domtools is a set of Unix shell commands that allow you to traverse DNS domain hierarchies, list all hosts (or subdomains) within a given domain, convert a host name to an IP address and vice-versa, convert a normal IP address to "in-addr.arpa." format and vice-versa, and more. These commands can be used manually, or included as building blocks for higher level DNS tools. Output is easily computer parsable.
The Download Slave is a very flexible script which is controlled via eMail and stores files requested for downloading on the server's harddisk or sends them via eMail to the user who asked for them. Users are identified by their eMail address and a personal password, so only authorized users can use the service.
