eth0 inet addr:192.168.171.130

Solution

Make sure the ssh server is actually running inside Ubuntu.

try # ps aux | grep ssh

or # netstat -anp | grep ssh

It probably just got another IP-adress this time. Your client should ask by DHCP, but vmware will give you a NAT-compliant ip-number.

can you ping it? is ssh server running on ubuntu? on port 22?

[RBA]

how can i check that,, whether ssh server is running on port 22 or not,, or if it is not working, then how to work it on..

[mmi]

Are you sure you bridged the network and the virtual network is not NATed?

[cop1152]

good call...gotta be running ssh server before connecting to it...I had this happen to me. I thought it was installed by default.

[RBA]

I am not able to ping guest machine. from windows..

[RBA]

I have switched the firewall off, but then also it is not working..

[RBA]

I donot find any information on port 22 by executing netstat on guest os

[RBA]

I have switched the firewall off, then also it is not working.. not able to ping guest os's IP from windows host os

This is the output of netstat,, please help sir..

If you can't find anything listening on port 22 (sshd) and you haven't changed anything from defaults, then it's not running sshd. That's why you can't ssh from the host into the guest (or in part that's the reason). What happens if you run sudo /etc/init.d/sshd restart (or sudo /etc/init.d/ssh restart)?

as root # aptitude install openssh-server and then netstat -anp | grep ssh
