Description Olivier Vitrat 2007-06-21 20:15:29 UTC

Version:            (using KDE KDE 3.5.5)
Installed from:    Debian stable Packages

Reported in Debian BTS at http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=386334 and http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=206843


ktalkd is set to run as nobody.tty in /etc/inetd.conf.  When I try to
connect to it I get this in /var/log/daemon.log

I think the "setgid/setuid as myuser: Operation not permitted" line is
the problem.  The same problem exists in Etch as well.

Same problem on latest Debian/Testing. Kde-3.5.9.

So people are still using ktalkd? That's amazing.
It has been removed from KDE 4, for two reasons: apparent lack of interest from users (IM has replaced talk for most people), and a large number of security issues (I wrote ktalkd before I knew anything about security, which is bad for a daemon running as root)....
Sorry, I don't think this bug will ever get fixed :(
