you can test if you issue<br />
<br />
iptables -I INPUT -p tcp --dport 23 -j ACCEPT<br />
<br />
and then try again from the client.

To make the changes permanent you should use the firewall configuration app.<br />
Menu -&gt; &nbsp;System Settings -&gt; &nbsp;Security level<br />
And check telnet as a trusted service

Hi<br />
<br />
I have a new Redhat 3.0 ES which has had telnet installed (and yes I know it is insecure!)<br />
<br />
The problem is I can telnet from the console but not from any client PCs, it can be ping'd and ftp'd to. The telnetd runs when connected locally. There is no specific iptables entry for telnet. xinetd is running and the telnet config file exists.<br />
<br />
The error below is reported <br />
<br />
C:\Documents and Settings\RCooper&gt;telnet 10.0.0.12<br />
Connecting To 10.0.0.12...Could not open connection to the host, on port 23: Connect failed<br />
<br />
How do I get it to respond?<br />
<br />
Thanks<br />
<br />

Telnet refusing connection

The variety of Linux distributions creates myriad issues relating to configuration and operations when computers are networked, not the least of which is the use of various network management applications, some of which are included with specific distributions, while others are standalone applications.
