polynomial-c@gentoo.org Lars Wendler A proxy DNS server with permanent caching (the cache contents are written to hard disk on exit) that is designed to cope with unreachable or down DNS servers (for example in dial-in networking). Linux-only: check status of ippp interfaces with ISDN-specific system calls. Linux-only: use /dev/urandom (pseudo-random number generation) instead of the default use of random() PRNG.
