tcp_wrappers for Debian ---------------------- Extensions: ---------- There are a number of Debian specific changes to TCP wrappers: * libwrap.so.0 is available for dynamic linking. * You can blacklist a whole bunch of hosts at once by specifying a file that contains a list of those hosts instead of just naming a host. See the hosts_access(5) manpage. Library versioning: ------------------ TCP wrappers isn't distributed as a shared library upstream, so the versioning scheme used for TCP wrappers may not match Linux's library versioning schme. Hence, libwrap has a soname of libwrap0 (version 7.6), instead of libwrap7 (version 6). Build options: ------------- STYLE = -DPROCESS_OPTIONS Debian TCP Wrappers use the extended syntax for /etc/hosts.allow and /etc/hosts.deny. This particularly affects spawning other commands on connections, see the hosts_options(5) manpage for more details. FACILITY = LOG_DAEMON SEVERITY = LOG_INFO TCP Wrappers logs as daemon.info (rather than mail.info). BUGS = Linux has no bugs. :) VSYSLOG = libc6 has vsyslog built in. UMASK = -DDAEMON_UMASK=022 NETGROUP = -DNETGROUP RFC931_TIMEOUT = 10 ACCESS = -DHOSTS_ACCESS TABLES = -DHOSTS_DENY=\"/etc/hosts.deny\" -DHOSTS_ALLOW=\"/etc/hosts.al low\" KILL_OPT = -DKILL_IP_OPTIONS The options ALWAYS_RFC931, ALWAYS_HOSTNAME and PARANOID have not been enabled because these features can be enabled at runtime. The option APPEND_DOT is not enabled because of compatibility reasons. -- Anthony Towns , Tue, 10 Aug 1999 12:06:33 +1000
