-We don't have a `lsof` tool. Perhaps we could cook something with having a
-look at which ports are open at the moment (as [[`portinfo`|hurd/portinfo]]
-does, for example)?

- <teythoon> braunr: there's something I've been working on, it's not yet
- finished but usable
- <teythoon> http://paste.debian.net/58266/
- <teythoon> it graphs port usage
- <teythoon> it's a bit heavy on the dependency-side though...
- <braunr> but
- <braunr> is it able to link rights from different ipc spaces ?
- <teythoon> no
- <teythoon> what do you mean exactly?
- <braunr> know that send right 123 in task 1 refers to receive right 321 in
- task 2
- <braunr> basically, lsof
- <braunr> i'm not sure it's possible right now, and that's what we'd really
- need
- <teythoon> does the kernel hand out this information?
- <braunr> ^
- <teythoon> right, I'm not sure it's possible either
- <braunr> but a graph maker in less than 300 is cute :)
- <braunr> 300 lines*
- <teythoon> well, it leverages pymatplotlib or something, it needs half of
- the pythonverse ;)
- <braunr> lsof and pmap and two tools we really lack on the hurd
- <teythoon> what does portinfo --translate=PID do?
- <braunr> i guess it asks proc so that ports that refer to task actually
- give useful info
- <braunr> hml
- <braunr> no
- <braunr> doesn't make sense to give a pid in this case
- <braunr> teythoon: looks like it does what we talked about
- <teythoon> :)
- <braunr> teythoon: the output looks a bit weird anyway, i think we need to
- look at the code to be sure
- <teythoon> braunr: this is what aptitude update looks like:
