I have a truckload of network connections lingering from a simple test
I did:

tcp 1468 network Closed 18001 7665 136.159.7.68

tcp 1481 network Closed 18001 8439 136.159.7.68
the remote machine has been rebooted long ago, but they still show in
Plan 9. how do I clean them up?

i don't think those are `lingering' in the sense that they are fin-wait-n
or similar; the directory entry will be reused when someone else needs it.
until then it shows the last call made through that directory.

bad choice of words... I meant 'should I be seeing those directories
in /net/tcp?' It's confusing when netstat reports them, though if
they're being reused it's acceptable :)

That's a hard question. `Should' by whose authority?
It's certainly normal, if unhelpful. I usually run `netstat | grep
-vi close' (`-i close' because the spelling and case of `Closed' used
to vary; it looks like they are standardised now). If I weren't
interested in listeners but only in established connections, I'd use
`netstat | grep Established'.
