 |
|
Two machines identically configured. On one, netstat returns
| Code: | tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN
tcp 0 0 127.0.0.1:3306 0.0.0.0:* LISTEN
tcp 0 0 45.76.6.231:497 0.0.0.0:* LISTEN
tcp 0 0 127.0.0.1:497 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN
tcp6 0 0 :::33060 :::* LISTEN
tcp6 0 0 :::80 :::* LISTEN
tcp6 0 0 :::22 :::* LISTEN
tcp6 0 0 :::443 :::* LISTEN |
On the other,
| Code: | tcp 0 0 localhost:mysql 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:ssh 0.0.0.0:* LISTEN
tcp 0 0 localhost:9000 0.0.0.0:* LISTEN |
Why is Apache showing up in one and not the other? More generally, why does one list IPv6 connectivity and the other not? |

| It turns out one server is slightly older than the other and is running an earlier kernel that somehow had been compiled differently. One has ipv6 and the other not. |

Furthermore, the first output was created with netstat option '-n' and the second one without that option...
'identical' is probably not the appropriate word... |
