/etc/xinetd.d/telnet Doesn't Exist To Disable Telnet

Sep 21, 2007

I decided to disable Telnet in my server. I get an Article ::

1. Login to your server through SSH and su to root.
2. Type pico /etc/xinetd.d/telnet
3. Look for the line: disable = no and replace with disable = yes
4. Now restart the inetd service: /etc/rc.d/init.d/xinetd restart
5. Turn off it through chkconfig as well because it can still start through that.
/sbin/chkconfig telnet off
6. Scan your server to ensure port 23 is closed.
nmap -sT -O localhost

Also run ps -aux | grep telnet and if you find anything other than "grep telnet" as result kill the process.

But /etc/xinetd.d/telnet doesn't exist in my server.

SSH Vs Telnet Access

Nov 20, 2006

I need help with understanding the difference between Telnet and SSH. I am in the process of signing up for a hosting plan and I have asked the sales rep if we will have telnet access. Their reply was that we have full root access via SSH.

Any help that anyone can offer on the differences and benefits/drawbacks would be much appreciated.

HTTP 1.1 Request Via Telnet (hostname Issue Maybe)

Jun 8, 2008

I have a script that makes a request via telnet and it worked on my old server, but not on the new one.. Heres what I'm doing

telnet localhost 80

GET /files/downloadFLV.php HTTP/1.1
Host: www.soybe.com
I get this back:

HTTP/1.1 404 Not Found
Date: Sun, 08 Jun 2008 06:34:25 GMT
Server: Apache
Last-Modified: Tue, 18 Mar 2008 06:52:59 GMT

I know that /files/downloadFLV.php does exist, so I'm thinking it could be an issue with the Host: part of it, any ideas?

FedoraCore2 - Cannot Telnet Out To Port 25, So Cant Send Email

Jun 23, 2005

if i try to telnet to yahoo's mail server, i get this:

[root: #] telnet mx1.mail.yahoo.com 25
Trying 4.79.181.14...
telnet: connect to address 4.79.181.14: Connection timed out
Trying 4.79.181.15...
telnet: connect to address 4.79.181.15: No route to host
Trying 67.28.113.11...
telnet: connect to address 67.28.113.11: No route to host
Trying 67.28.113.10...
telnet: connect to address 67.28.113.10: No route to host

but it works from one of my other hosted servers.
this keeps mail building up in my queue as it cannot send mail out cause the connection times out.

I can telnet locally to send myself email. This is my own dedicated server.

i have no idea whats up - default policy is ACCEPT in the OUTPUT chain of iptables.
