Since the environ array can be manipulated directly without system calls, ltrace probably wouldn't show this (and ltrace would produce a long listing for something like konsole). KDE developers should be able to answer the question with only a few moments' thought. There are other variables that are also removed from setuid programs, but LD_LIBRARY_PATH is the most noticeable (I don't have a list at hand). > If there's no easy way to do this, I guess I have to move the bug over > to kdm and take it from there... That sounds right. > Andreas > > PS: Can it be, that this only happens with the "new" libc? Because I > know for sure that some time back (maybe even half a year..) it worked. no - this has been (with xterm anyway) an issue for 4-5 years. If xterm's not setuid, it'll still work except for the utmp feature. I usually test xterm during development without setuid. Occasionally I see some comment regarding systems where the setuid's been removed, etc. Perhaps you were using one of those. -- Thomas E. Dickey http://invisible-island.net ftp://invisible-island.net
