Dear Flocks,
Recently i installed RH Fedora core 3 as a server and started telnet service to enable remote login feature in windows network. telnet is working only when i connect the other linux mechines from this server but when i connect through windows command prompt or other linux mechines the following error is showing.

telnet 192.167.0.4

Connecting To 192.167.0.4...Could not open connection to the host, on port 23: Connect failed

but i ping this server it gives responses. i tried this by disabling firewall service and selinux features (i don't know much of this ) and again the same error is showing.

when i try from the other linux mechine it shows the follwing error:

[abi@localhost abi]$ telnet 192.167.0.4
Trying 192.167.0.4...
telnet: Unable to connect to remote host: Connection refused

please help me ...

Disable telnet and use ssh instead. Telnet is an insecure protocol and there's a reason it's not enabled by default (because you're not supposed to use it).

Download and install PuTTY on your Windows machine to access your Linux systems.

So you got problem with Telnet, did you enable telnet from /etc/xinetd.d/telnet open this file instant "disable = yes" put "disable = no" then restart ur xinetd service

Are you from Silicon Valley, USA, Do you know Devry University ?

Don't use telnet - use ssh instead. Telnet is not secure

Also, don't use FC3 on a server - that hasn't been supported for quite some time and is not receiving security updates. I don't recommend Fedora for servers - the lifecycle is too short. If you like the basic Fedora setup, try CentOS, the free version of RedHat

Rahil, there really isn't a good reason to give bad advice. Why did you quote chort in that response?

I am Sorry I know its not secure,I thought he just wanna learn how troubleshoot it with telnet.

There are Devry campuses all over the USA, but I'm not sure what that has to do with anything?

Yes I live in Silicon Valley. I'm within a few miles of Sun, IBM, Intel, AMD, Symantec, EMC, McAfee, Google, Cisco, etc... I work right across the road from Yahoo! and Juniper.

Putty is a great program and works very well for this application. SSH is the way to go.

You might consider installing Cygwin/X on your windows machine. Then you can use the ssh client in the bash shell. You can even use "ssh -X hostname command" to start a graphical command. The server doesn't need to be in "init level 5" as long as the base Xorg libraries are installed.

Yeah, I dont know much but Im learning I also want to become like u guyz, by the way im student, and it is good u post mail abt me and I will appreciate if u guyz help me where I make mistakes.

let me know wht do you mean by customer service of American based company, I just ask Chort bcoz next month Im going to US in Devry University for further studies.

Well, U told after installing Cygwin on window we can run SSH client is it works, I would like to know more abt it.

Here is where you can download the install program:
http://x.cygwin.com/

It will also allow you to run console programs in the bash shell such as awk, perl, grep, vim, LaTeX, etc.

You can also install some x windows based programs like xpdf, xv, etc.
running "startxwin" in cygwin will start an X server so you can log into any Linux or Unix host that runs Xdmcp. Otherwise you can ssh into a server and start a graphical or console program. Y

ou can set up your key pair the same way or even copy your keys from Linux if you are dual booting. ( You can do the same with putty or use putty's keygen program to display an openssh compatible public key which you can cut & paste for use in the servers .ssh/authorized_keys file. )
