[Request] fuser for Maemo 5 / N900
 
Hi all,

The fuser app that comes built-in to the Busybox shipped with the N900 is broken. It just doesn't work. At all.

The psmisc package found in Extras-devel has a working fuser binary, but it does bad things to your Maemo install, removing the busybox-symlinks-psmisc package, which then removes the very important mp-fremantle-generic-pr package, making it impossible to do over-the-air firmware updates! :eek:

So I would like someone to make a package that contains a "safe" version of fuser. This will probably mean that you have to call it a different name ("gnufuser" or "gfuser" or something), and maybe, if you're feeling a bit naughty, you could move the symlink for "fuser" from busybox to the new "gnufuser" in your postinst, but without removing the "busybox-symlinks-psmisc" package.

Without a working fuser, I can't kill chroot apps, a very important part of my Easy Debian system.

I agree something should be done about fuser, it does not work for me either. There seems to be no way to tell which process listens at a port!

Private Message.. I sent the op a link to a deb I built to test.

If it works for him I'll see about getting it out there.

Some people can get a lot of PM's and tend to filter.. so I was leaving a note in the thread it was related to so the OP could determine importance.

Hmm .. I thought "netstat -anp" or "lsof -i tcp:<PORT>" could be of help, but both of these don't work either ...

Yeah, I am trying to utlize netstat and lsof, but I am a little bit confused with the results I get, cf. http://talk.maemo.org/showthread.php?t=31373&page=3

Just curious.. did mine not work?

fatalsaint, I confess that I haven't tried yours (I will, soon). Even if it does work, it doesn't fix the bug, which is in Busybox, the all-in-one, do-everything, coreutils-replacement that ships with the device. It worked in Chinook, it worked in Diablo, but it is broken in Fremantle.

Fair enough. Then I guess you don't need to worry about it.. since there wouldn't be a point in pushing it any further even if it does work and just wait for the BUG to get addressed.

Well a safe fuser package in extras would be a welcome workaround until Nokia pushes a fixed busybox... Which may never actually happen...

That was the intent of the deb I sent qole.. it was psmisc in a deb that used a trick I was hoping would allow for clean replacement of the busybox-symlinks.

Ok, I wasn't entirely sure how well the dependencies would be handled.

Thanks.
