Telnet problem in RHEL5
Please help me telnet to my RHEL5.
I change disable=yes to disable=no in the /etc/xinetd/telnet and restart the xinetd service successfully but I am still getting the following error message:
C:\Users\laptop>telnet 10.7.2.103
Connecting To 10.7.2.103...Could not open connection to the host, on port 23: Connec
t failed
Regards,
Berenger

Re: Telnet problem in RHEL5
This would confirm you that everything is working as expected.
If it is working, check your firewall rules.

Re: Telnet problem in RHEL5
Use this:
chkconfig --list | grep telnet
to find out telnet's status.
To enable telnet, use:
chkconfig telnet on
after that command, the:
chkconfig --list | grep telnet
should show you that telnet is enabled (on).

ekrb5-telnet: on
krb5-telnet: on
telnet: on
Stop the krb5 servers:
chkconfig ekrb5-telnet off
chkconfig krb5-telnet off
service ekrb5-telnet stop
service krb5-telnet stop
Start the telnet service:
service telnet start

Re: Telnet problem in RHEL5
If you use windows on your laptop, a free ssh client would be putty:

Re: Telnet problem in RHEL5

Re: Telnet problem in RHEL5
have you tried to open the telnet port in the firewall, if you have a firewall active, that is.
