Now, your netstat output shows that the listener is only using ipv6, so lets try forcing it to ipv4. No idea if this is the issue or not -- Does your laptop show the same netcat output? To force to IPV4 on your desktop: $ sudo vi /etc/ssh/sshd_config At the top, uncomment ListenAddress <a href="http://0.0.0.0" target="_blank">0.0.0.0</a> And then $ sudo /etc/init.d/ssh restart</blockquote><div> ok, i did exact that. sudo /etc/init.d/ssh restart * Restarting OpenBSD Secure Shell server sshd [ OK ] </div></div>still, when i tried to connect from laptop, it didn't work. netcat out put from laptop is not the same as the one from desktop. from desktop: tcp 0 0 <a href="http://0.0.0.0:22" target="_blank">0.0.0.0:22</a> 0.0.0.0:* LISTEN unix 2 [ ACC ] STREAM LISTENING 29681 /tmp/orbit-xinyue/linc-1c75-0-1da3daf222050 unix 2 [ ACC ] STREAM LISTENING 32322 /tmp/orbit-xinyue/linc-1d74-0-380e8440f14f2 unix 2 [ ACC ] STREAM LISTENING 32524 /tmp/orbit-xinyue/linc-1d78-0-4a73be62218ae from laptop: tcp6 0 0 :::22 :::* LISTEN unix 2 [ ACC ] STREAM LISTENING 21735 /tmp/orbit-zhengguo/linc-177a-0-3b77f1c4f2228 unix 2 [ ACC ] STREAM LISTENING 22252 /tmp/scim-bridge-0.3.0.socket-1000@localhost:0.0 unix 2 [ ACC ] STREAM LISTENING 22777 /tmp/orbit-zhengguo/linc-1801-0-354a40bdf22b0 unix 2 [ ACC ] STREAM LISTENING 22810 /tmp/orbit-zhengguo/linc-1803-0-28fd485411c25 ps -ef | grep fire gives only firefox. ssh -w: ssh: option requires an argument -- w usage: ssh [-1246AaCfgKkMNnqsTtVvXxY] [-b bind_address] [-c cipher_spec] [-D [bind_address:]port] [-e escape_char] [-F configfile] [-i identity_file] [-L [bind_address:]port:host:hostport] [-l login_name] [-m mac_spec] [-O ctl_cmd] [-o option] [-p port] [-R [bind_address:]port:host:hostport] [-S ctl_path] [-w local_tun[:remote_tun]] [user@]hostname [command] it seems i need to type sth more but i have no idea what. by the way, did it matter that i installed packages like apache, mysql etc on desktop (since it was used as server) but not on laptop? </div>
