Hi out there, I have a few questions...... 1. I have SuSe Linux 6.0 running a custom application. I have to increase the amount of open files that the program uses but when i use the ulimit -n command it returns an error saying operation not permitted. is there any other way without rebuilding or upgrading the kernel that i can increase this value?. 2. If i have to rebuild the kernel to support this new value what source files do i have to modify? 3. if i have to upgrade the kernel what exactly do i need to do it on SuSe 6.0? I have downloaded 2.4.12 and all the updates for SuSe 6.0 4. Would it be easier to upgrade to a later version and does the later version allow me to increase the amount of open files? Any help regarding these questions would be grately appreiciated. Regards John Mc Cabe
