Problem with Cyrus

[neelu_dhiman at persistent.co.in]

Hi,
I have installed and configured cyrus-imapd-2.3.7 and
cyrus-sasl-2.1.22 on my Linux (FC 4) machine. I am able to
telnet to my server on imap port. I am also able to get
"cyradm" prompt when I type "cyradm" on cmd line. But,
whenever I try "cyradm localhost", then I get no prompt(only a
blank line) . Following is the output: 
[cyrus at ps3151 neelu]$ cyradm localhost


The same thing (just empty line) happens when I try "imtest -m
login -p imap localhost". I should get some prompt asking my
password etc., but I am getting no prompt. 

I have followed all the installation and configuration steps
very well. I couldn't trace out what can be missing. Can you
please help me? This is very crucial for me.
Thanks a lot,
Neelu.
