First of all, I want to wish all of you and your families a prosperous and happy new year. May all of you be blessed and thrive.
Now my question. I recently obtained a Ubuntu linux server. It has OpenSSH running on port 22. I can do a "ssh localhost" on the server and it works fine. I have created a private key for my user and then added it to my laptop through PuTTYgen. However, when I try to connect to the server, I get Connection Timeout error. I have tried following things so far
1] I have Norton AV and firewall. I disabled them.
2] Used ehternet instead of wireless
3] Disabled firewall from Linux server.
Still the problem remains. One more interesting thing I see is that, I can ping my laptop from the server but not the other way around. If I looked at the arp table on my laptop, I can see the server IP address. However the ping does not go through.
Further, I can access the website hosted on the server from my laptop. So the physical connectivity is not a problem.
Any suggestions will be greatly appreciated.
