[opensuse] connection refused on telenet command
I have disabled the firewall of opensuse 42.3. I am trying to set up my machines so that I can use netconsole to log messages that would normally be sent to the serial port on boot failure. I cannot get telnet to send a message to the host it is on. nc -l -u 23 | tee ~/netconsole.log is the command listening telnet dfpcxx is telnet command entered. I receive: telnet: connect to address 192.168.7.xx: Connection refused Since the firewall is disabled, what is refusing the connection? I get nothing in /var/log/messages and nothing in dmesg. Is this some damn PAM or other thing that is lurking unseen and unreported in the background? Any help would be appreciated.

Could you show separately the command you do on each computer, complete with command prompt, options, results? I fail to understand what you are doing, sorry. -- Cheers / Saludos, Carlos E. R. (from openSUSE 15.0 (Legolas))

To me it looks like you have set up for receiving UDP traffic, but telnet speaks TCP ? -- Per Jessen, Zürich (10.6°C) http://www.hostsuisse.com/ - virtual servers, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Yes, I commented on that :-) -- Cheers / Saludos, Carlos E. R. (from openSUSE 15.0 (Legolas))
