Is there a way to know WHEN a connection has been established?

Question

I'm working with mobile IPv6 and was dealing with lots of zombie connections. I set keepAlive to true and want to test whether old connections are being discarded.

I'm using lsof to list the process connections, but I can't tell how old the connection is.

Is there a way to verify this?

Answer 1

netstat -nlp

• -n for not resolving the ips
• -l for listening sockets. Skip this if you want to list outgoing connections
• -p to show executable name (last column) and process id

edit:

ow. WHEN. That kind of information is not kept... Well at least for TCP/IP. If it's a unix socket you can try with socket file times (created, modified ...)
