Re^2: System and CGI - File Created but not the Content

[monkfan]

Hi moritz,
Yes it seems that it uses SELINUX, since I'm with:

Enterprise Red Hat 4.1.1-52

I tried strace with the following snippet in my script.pl:

system("strace -o $my_repo /home/monkfan/bin/ameme /home/monkfan/publi
+c_html/FOO/input_files/input_file.txt param1");

It doesn't seem to give any error message and it gives the following:

execve("/home/ewijaya/bin/ameme", ["/home/monkfan/bin/ameme", "numMoti
+fs=10", "rcToo=off", "good=/home/monkfan/public_html/FOO"...], [/* 28
+ vars */]) = 0
