Hi all,

I've been meaning to provide a simple UI over a command-line tool automation done with bash scripting, and some of the processing being possibly lengthy, I wanted to use a progressbar at times.

kdialog provides a --progressbar mode which works through DCOP references.

Although what's in the documentation works swell in regular mode, if I run my script via sudo (which I have to do since it requires root privileges and setuid'ing the script after making root:root its owner/group doesn't seem to cut it), it doesn't seem to work: I do get the reference, but attempting to use it, e.g. like this:

dcop $dcopRef setProgress 1

invariably returns a "object inaccessible" error.

I tried using various parameters on dcop, e.g. --all-sessions or --user proper_userid, but this doesn't help.

There are two things that could help me out here:
1) a way to make my command-line tool get its job done w/o root access (but that's another story, and that doesn't help me know DCOP issues better)
2) a way for DCOP references in my context to work within sudo!

Ideas, anyone?

Thanks!

Hi,

I had first tried your suggestion the other way around, that is, creating it as root then dcop'ing it as a user. It doesn't work. I had tried it before, but FYI, here's what it does:

- if I try dcop --user root as is, I get a warning because it doesn't find /root/.ICEauthority.

- if I export ICEAUTHORITY to my user's profile (the one from which sudo was done, and sudo doesn't modify $HOME), then retry, dcop hangs.

Then, about your idea: creating it in userland, than accessing it as root. Of *course* it works, since sudo preserves $HOME and root is, well, root.

However, when the DCOPRef is created within a sudo'd script, the same script, still running, cannot access the DCOP ref.

I think DCOP fails to register the DCOPRef in the proper space, somehow. I just don't know the details...
