WILD GUESSES #1 (benign) Your 'apache' user on the bad box has some kind of cool shell color-coding going on. The color-coding puts out control characters for directories, users, permissions, and masks weird-o characters in filenames. Those control characters, when presented to you in a browser/text rather than a shell context, show up as funky-ass things like ? and that diamond-shaped inverse ? thing. You can diagnose this pretty easily, really. When you su to apache on the bad box and do "ls -ld /" do you get all kinds of pretty colors and stuff? Well, there ya go. Make it not do that. You're on your own figuring out how to do that. To me, it's just some magic that's sometimes on some Un*x boxes, and sometimes not, and that's how life goes. :-) [I don't care enough either way about the color-coding to find out, much less remember, how to change it either way.] #2 (panic) EXTREMELY UNLIKELY: You've been hacked and the 'ls' binary has been replaced with something that does something else very weird, but you don't see it under shell conditions... #1 is almost for sure the real answer... But if it's #2, you'd better act carefully.

Hi Richard. Although "ls -ld /" returns some color, that is not the problem. I tried within PHP ls --color=never -ld / and it fails to. ls is not the only command having problems. I tried other commands like find /lmw -name '*' and cd /lmw and they fail because of bad permissions. Could it be because of SELinux? I wonder. I think that Apache runs under some SELinux restrictions and that might be the problem. I will investigate and report on this. Ciao, Hans Deragon -- Consultant en informatique/Software Consultant
