| 366921 | 2005-06-25 03:46:00 | I recently went to an online port scanner just to see how secure my linux setup was. It reported back that Telnet was open. How do I shut it? I am using D-Link 504g switch modem, 2 which this computer and a Windows box are connected via ethernet cable. I have unchecked the Allow Telnet on the switch/modem. I am thinking that IPtables is the next on the list to shut this hole. In services, Telnet is not listed. I am using FC4 with SELinux, and the default firewall. What can I do now? |

| 366922 | 2005-06-25 04:06:00 | Do Ctrl/Alt/F2. That should give you a black screen "login:" Log in (not as root), then do: telnet 127.0.0.1 It should give an error message: "Connection refused by remote host" or something like that. That will mean that there's no telnet server running (and you know that). So it doesn't matter that the telnet port 23 is open. If noone's listening, there's no problem. Ctrl/D should close that session. Ctrl/Alt/F7 should get you back to the GUI. |
