%general-entities; ]> TCP Wrapper The TCP Wrapper package provides daemon wrapper programs that report the name of the client requesting network services and the requested service. This capability is obsolete in a modern environment, but several applications still use the library and associated configuration files. &lfs70_checked; Package Information Download (HTTP): Download (FTP): Download MD5 sum: &tcpwrappers-md5sum; Download size: &tcpwrappers-size; Estimated disk space required: &tcpwrappers-buildsize; Estimated build time: &tcpwrappers-time; Additional Downloads Required Patch (Fixes some build issues and adds building a shared library): User Notes: Install TCP Wrapper with the following commands: patch -Np1 -i ../tcp_wrappers-&tcpwrappers-version;-shared_lib_plus_plus-1.patch && sed -i -e "s,^extern char \*malloc();,/* & */," scaffold.c && make REAL_DAEMON_DIR=/usr/sbin STYLE=-DPROCESS_OPTIONS linux This package does not come with a test suite. Now, as the root user: make install sed -i -e ... scaffold.c: This command removes an obsolete C declaration which causes the build to fail if using GCC >= 3.4.x. /etc/hosts.allow and /etc/hosts.deny /etc/hosts.allow /etc/hosts.deny Installed Programs Installed Library Installed Directories tcpd, tcpdchk, tcpdmatch, try-from, and safe_finger libwrap.{so,a} None Short Descriptions tcpd is the main access control daemon for all Internet services, which inetd or xinetd will run instead of running the requested service daemon. tcpd tcpdchk is a tool to examine a tcpd wrapper configuration and report problems with it. tcpdchk tcpdmatch is used to predict how the TCP wrapper would handle a specific request for a service. tcpdmatch try-from can be called via a remote shell command to find out if the host name and address are properly recognized. try-from safe_finger is a wrapper for the finger utility, to provide automatic reverse name lookups. safe_finger libwrap.{so,a} contains the API functions required by the TCP Wrapper programs as well as other programs to become TCP Wrapper-aware. libwrap.{so,a}
