Hi, I recently installed Red Hat linux 7 on a machine in our cluster. Everything was working perfectly for about a week. We had installed the old libc libraries using the rpm for compatability under RedHat6.2 in order to run Matlab5.x and Matlab6. This also seemed to be working fine for several days. With no other changes to the system since the basic installation, suddenly "ls" no longer lists files for non-root users. Is this a problem with the old libraries, or has the system been compromised? Thanks Gayel
There is no problem with the compatibility libraries (unless you installed them to replace the current ones, make sure you installed libc and ld.so, but not glibc for the old libraries!). If you did it correctly, ls not working is someone else's doing.
