hi , I am unable to connect to another machine using ssh
ssh kartik@172.17.11.252
it gives an error ssh: connect to host 172.17.11.252 port 22: Connection refused
when I ping , it works fine

ssh is working fine for some other servers like 192.168.36.205 and sshd is also running
Please help

Well, "connection refused" normally means that sshd is not
running on the target machine, here 172.17.11.252

If "ssh localhost" works on 172.17.11.252 there might
be something else causing trouble, e.g. a firewall.

After upgrading to Karmic 9,10, I could not get SSH to work. Problem solved. SSH is not installed automatically - you have to install it yourself with Synaptic or APT-get.
