How to enable telnet server

  • 772

I followed these instructions but when doing telnet localhost or telnet localhost 23, getting unable to connect to remote host: connection refused. I also shut down firewall: sudo ufw disable.

When doing sudo /etc/init.d/xinetd status I get active (running)

I can do telnet to the internet e.g. telnet google.com 80 (I know this is telnet client)

More information: version 18.04.1 TLS, running on Oracle VM VirtualBox.

18.04 telnet

  1. Create following file:

    vi /etc/xinetd.d/telnet

    content:

    service telnet
{
disable = no
flags = REUSE
socket_type = stream
wait = no
user = root
server = /usr/sbin/in.telnetd
log_on_failure += USERID
}

    restart service. I think this does the trick.

  2. I had a problem like this after following ( http://ubuntuguide.net/install-and-enable-telnet-server-in-ubuntu-linux ) but I saw an error /var/adm/syslog:

     xinetd[11406]: execv( /usr/sbin/tcpd ) failed: No such file or directory (errno = 2)

    Problem solved by installing tcpd

    sudo apt-get install tcpd
