telnet don't work

Justo Exposito — Wed, 05 Dec 2001 15:40:18 GMT

Hello,

I just installed a Mandrake 7.2 Linux box, and when I try to telnet from other machine I obtain the message "Conexion refused by host", but when from the linux box I do telnet to other box all works fine.

Somebody can help me?

Thanks in Advance.

U have to discomment the line
#telnet stream tcp nowait root /usr/sbin/tcpd in.telnetd
from /etc/inetd.conf or similar and restart the inetd service. Check also the file /etc/hosts.allow, if you want accept just telnet connections (inetd services) use:
in.telnetd: ALL
or
in.telnetd: xxx.xxx.xxx. from a network
or
in.telnetd: xxx.xxx.xxx.xxx
you can use both too...

Ok?

Leandro.

You can use both separated by (,):

in.telnetd: xxx.xxx.xxx., xxx.xxx.xxx.xxx

where xxx.xxx.xxx. for a network and xxx.xxx.xxx.xxx for IP address.

Hi,

I suppose Mandrake 7.2 uses xinetd. If so, in /etc/xinetd.d/telnet, you have a line like:

disable = yes

it's the default for most of the daemons. Change it to 'no' and /etc/rc.d/init.d/xinetd restart

Correct me if I'm wrong, but I was under the impressions that Mandrake doesn't install telnetd by default instead relying on using sshd. Check to see if telnetd is installed on your system (rpm -qa |grep telnetd). If its installed then check that the daemon is set up to start by xinetd as mentioned above. You can also see if xinetd is listening on port 21 (netstat -na|grep 21|grep LISTEN).

Hope this helps.
