Find the telnet-server in CentOS7.2

Question

I use yum installed telnet-server in my CentOS-7.2:

yum install -y telnet-server

The above prints:

Downloading packages:

Completed！
[root@localhost ~]# vim /etc/xinetd.d/telnet
[root@localhost ~]# find / -name telnet
[root@localhost ~]# find / -name telnet-server

You see, I searched for telnet and telnet-server, but did not find it. Where the telnet is? How can I find it and its config file?

Answer 1

The telnet-server package installed the telnet daemon (telnetd) at:

/usr/sbin/in.telnetd

The configuration for it can be found in the man pages:

man in.telnetd

In general, you can list the files that installed by an RPM by querying the RPM database:

rpm -ql telnet-server

... which in this case would give you an output like:

/usr/lib/systemd/system/telnet.socket
/usr/lib/systemd/system/[email protected]
/usr/sbin/in.telnetd
/usr/share/man/man5/issue.net.5.gz
/usr/share/man/man8/in.telnetd.8.gz
/usr/share/man/man8/telnetd.8.gz
