Recent Linux kernels do not allow access to environment strings via ps, except for the user him/herself. That is, /proc/*/environ is protected 400. This could confuse people reading your instructions, since they would see environments for their own process but not root's. To verify environment strings of login, you need to run ps as root. It took me a while to reproduce the problem on my machine, since I didn't look closely enough at the output of ldd, and I made /etc/libc.so instead of /etc/libc.so.4 . Onward to fix my telnetd 8-) . - Larry Doolittle ldoolitt () cebaf gov ------- End of Forwarded Message
