%general-entities; ]> Xinetd xinetd is the eXtended InterNET services daemon, a secure replacement for inetd. &lfs7a_checked; Package Information Download (HTTP): Download (FTP): Download MD5 sum: &xinetd-md5sum; Download size: &xinetd-size; Estimated disk space required: &xinetd-buildsize; Estimated build time: &xinetd-time; xinetd Dependencies Optional TCP wrappers (deprecated) User Notes: Install xinetd by running the following commands: sed -i -e "s/exec_server/child_process/" xinetd/builtins.c && sed -i -e "/register unsigned count/s/register//" xinetd/itox.c && ./configure --prefix=/usr --mandir=/usr/share/man --with-loadavg && make This package does not come with a test suite. Now, as the root user: make install sed ... xinetd/builtins.c: This command fixes a security issue. sed ... xinetd/itox.c: This command fixes some compiler warnings. /etc/xinetd.conf and /etc/xinetd.d/* /etc/xinetd.conf /etc/xinetd.d/* Ensure the path to all daemons is /usr/sbin, rather than the default path of /usr/bin, and install the xinetd configuration files by running the following commands as the root user: cat > /etc/xinetd.conf << "EOF" # Begin /etc/xinetd # Configuration file for xinetd defaults { instances = 60 log_type = SYSLOG daemon log_on_success = HOST PID USERID log_on_failure = HOST USERID cps = 25 30 } # All service files are stored in the /etc/xinetd.d directory includedir /etc/xinetd.d # End /etc/xinetd EOF All of the following files have the statement, "disable = yes". To activate any of the services, this statement will need to be changed to "disable = no". The following files are listed to demonstrate several xinetd applications. In many cases, these applications are not needed. Some classic applications are considered security risks. For example, telnet, rlogin, rexec, and rsh transmit unencrypted usernames and passwords over the network and can be easily replaced with a more secure alternative: ssh. install -v -d -m755 /etc/xinetd.d && cat > /etc/xinetd.d/systat << "EOF" && # Begin /etc/xinetd.d/systat service systat { disable = yes socket_type = stream wait = no user = nobody server = /bin/ps server_args = -auwwx only_from = 128.138.209.0 log_on_success = HOST } # End /etc/xinetd.d/systat EOF cat > /etc/xinetd.d/echo << "EOF" && # Begin /etc/xinetd.d/echo service echo { disable = yes type = INTERNAL id = echo-stream socket_type = stream protocol = tcp user = root wait = no } service echo { disable = yes type = INTERNAL id = echo-dgram socket_type = dgram protocol = udp user = root wait = yes } # End /etc/xinetd.d/echo EOF cat > /etc/xinetd.d/chargen << "EOF" && # Begin /etc/xinetd.d/chargen service chargen { disable = yes type = INTERNAL id = chargen-stream socket_type = stream protocol = tcp user = root wait = no } service chargen { disable = yes type = INTERNAL id = chargen-dgram socket_type = dgram protocol = udp user = root wait = yes } # End /etc/xinetd.d/chargen EOF cat > /etc/xinetd.d/daytime << "EOF" && # Begin /etc/xinetd.d/daytime service daytime { disable = yes type = INTERNAL id = daytime-stream socket_type = stream protocol = tcp user = root wait = no } service daytime { disable = yes type = INTERNAL id = daytime-dgram socket_type = dgram protocol = udp user = root wait = yes } # End /etc/xinetd.d/daytime EOF cat > /etc/xinetd.d/time << "EOF" # Begin /etc/xinetd.d/time service time { disable = yes type = INTERNAL id = time-stream socket_type = stream protocol = tcp user = root wait = no } service time { disable = yes type = INTERNAL id = time-dgram socket_type = dgram protocol = udp user = root wait = yes } # End /etc/xinetd.d/time EOF /etc/xinetd.d/login /etc/xinetd.d/shell /etc/xinetd.d/exec /etc/xinetd.d/comsat /etc/xinetd.d/talk /etc/xinetd.d/ntalk /etc/xinetd.d/telnet /etc/xinetd.d/ftp /etc/xinetd.d/tftp /etc/xinetd.d/systat /etc/xinetd.d/finger /etc/xinetd.d/netstat /etc/xinetd.d/echo /etc/xinetd.d/chargen /etc/xinetd.d/daytime /etc/xinetd.d/time /etc/xinetd.d/rstatd /etc/xinetd.d/rquotad /etc/xinetd.d/ruserd /etc/xinetd.d/sprayd /etc/xinetd.d/walld /etc/xinetd.d/irc The format of the /etc/xinetd.conf is documented in the xinetd.conf.5 man page. As the root user, install the /etc/rc.d/init.d/xinetd init script xinetd.service unit included in the package. xinetd make install-xinetd As the root user, use the new boot script systemctl command to start xinetd: /etc/rc.d/init.d/xinetd start systemctl start xinetd Check the /var/log/daemon.log journalctl output to ensure the appropriate services are started. If no services are enabled, the program will not start without the -stayalive option.
