On Linux, you need to configure whoson to use a TCP socket (not a Unix domain socket), but bind it to "localhost" for security. The /etc/whoson.conf entries would be: client tcp port=9876 address=127.0.0.1 server tcp port=9876 listenq=5 keepalive=150 allow=127.0.0.1/32 server global ttl=660 # 11 minutes chroot=/var/empty # chdir and chroot here group=whoson # change group id and user=whoson # user id after bind()ing cachesize=100000 # max. number of entries to keep -- Alexander Peslyak <solar at openwall.com> GPG key ID: B35D3598 fp: 6429 0D7E F130 C13E C929 6447 73C3 A290 B35D 3598 http://www.openwall.com - bringing security into open computing environments Was I helpful?
