Dear All,

I have installed Radhat 7.2 workstation in a windows 2003 based DHCP enabled network. I have reserved an IP for the linux machine. I have not been able to telnet into the machine. every time I get a message " connection refused". I have even allowed all in hosts.allow file. I even removed all security tools like ipchains, and tcpwrappers but no success.

I had even checked no firewall during installation.

Please help me out.

Why? Why would you do such a thing? Why would you remove every security tool in an attempt to run a completely insecure remote login protocol? Did it ever occurr to you that there's a good reason why it's so hard to do something like this? I really, really don't understand why people complain about the insecurity of Windows, then they switch to Linux and try to make it as completely insecure as possible.

Sorry I'm getting a little carried away here. The answer is that you should not use telnetd, because it's completely insecure. Use SSH (sshd) instead, that's what it's installed for.

Also if you would have searched either the security or the networking forum, you would have found this same answer many times.

I have even tried ssh and get the same connection refused. please advice.

Run a traceroute to the box, then run your ssh session adding verbosity flags "-v -v". Post result.

Maybe this is obvious, but... have you installed telnet-server package?
red hat only installs telnet client by default.

Regards

Do you have the sshd service turned on?

What's the output of:
$ netstat -anF inet

When you boot up and it scrolls the serivces that it's turning on, does it list ssh?
Check in /etc/rc.d/rc3.d and see if there is a symlink to /etc/rc.d/init.d/sshd, and see what the name is (ls -l /etc/rc.d/rc3.d), or if you're running in graphical mode I believe you need to check rc5.d.

Is ssh even installed?
$ rpm -qa|grep -i ssh
