So, important system calls could be modified thus: Since there are tons of syscalls and new ones appearing all the time, "Fixing" some of them doesn''t seem like a good idea.

dtrace causing sigtrap?
Just to let people know what my big picture is, I''m trying to write a script that will let me run a program, and name a progeny of that program that I want to debug. My script should find the first occurrence of that progeny, and run it until it finishes initializing the runtime linker, but stop it before it runs any shared library startup routines. (Failing that, I''d be okay

Passing arguments to forked children
Hi - I have attempted to use the fork::fork() function to perform parallel processing. However, the child R function called needs to know a given set of parameters to complete its task. Specifically, I iterate through a vector, and output values based on the elements of that vector to a database. The output strings contain elements of the iterated vector. I mocked-up the following code as an

Printing from Samba to Authenticated printer on W2K3 in ADS
Greetings, I have a pack of SunRay network computers in kiosk mode and I need to print to the Pharos printing system. Not surprisingly, Pharos runs on Windows. It is currently set up on Windows 2003 server. To print to this system you have to authenticate to the Activate Directory the Pharos server is a member of. I thought my best bet to pull this off was to use Samba. The

Managing git submodules with git.rake
Hey all, If you''re like me and use git submodules heavily (I vendor everything, and every plugin is a submodule), you might like to hear about code published this morning to make it easier to manage multiple git submodules in a shared-server environment. It''s imaginatively titled ''git-rake'', and it does Good Things like: * aggregates submodule commit logs into

Malicious Linux modules
As halflife demonstrated in Phrack 50 with his linspy project, it is trivial to patch any system call under Linux from within a module. This means that once your system has been compromised at the root level, it is possible for an intruder to hide completely _without_ modifying any binaries or leaving any visible backdoors behind. Because such tools are likely to be in use within the hacker

Needed help to fix corrupted ext3 fs
I have been trying very hard to seek help with my very complex issue but so far none have been successful. So I would like to try this mailing list, maybe there are some experts who know what they're talking about. Please refer to my experts-exchange question, all the required information will be there. It is more practical to send you to the webpage than paste out what I've done.

mount toption: nodev
Hi, I am trying to secure my CentOS file systems by introducing "nodev" to devies defined in /etc/fstab. I learned that "nodev" prevents users from mounting unauthorized devices. However, I can still mount a cdrom to /tmp/cdrom with the following defined in /etc/fstab. Am I missing something? Thanks. LABEL=/tmp /tmp
