Hi,

There is a few things that you can check:
- check if the ssh daemon is actually running:

service sshd status

if not start it

service sshd start

- check if firewall is not blocking port 22 if you haven't change from the default one
- check your vmware network and if you can access your VM from Windows machine at all(ping etc.)

Hi raji10k,

If HTF's stuff doesn't work, you may have used the wrong network model in VmWare for your Linux VM. It might be a good idea to temporarily turn off your VM's firewall with something like (as root):

[brian@bmicek ~]$ /etc/init.d/iptables  stop
[brian@bmicek ~]$ /etc/init.d/ip6tables stop

then try to ping your VM from your Windows host. If you want to run servers like sshd on your VM, I'm pretty sure you want to avoid any type of NAT presented by VmWare because its more tricky ... it doesn't mean you can't do it, it will just be more difficult.

check your /etc/ssh/sshd.conf and also hosts files.

may be any host which you want to connect, is blocked in hosts files. please tell me.. what exact error you have facing..??

Shot in the dark here. Time to check the most basic connection things.

1. What are the IP addresses on both machines?
2. Are they both in the same subnet?
3. Can you ping from XP to RHEL vm?
4. From XP box command prompt , try tracert <ip_of_RHEL_vm>

"if both systems are not have same subnet , will they connect using putty."
