Dear all: In dtrace.c, function dtrace_probe_create(), there''re a piece of code: id = (dtrace_id_t)(uintptr_t)vmem_alloc(dtrace_arena, 1, VM_BESTFIT | VM_SLEEP); id is uint32_t, and I think id is used as an index to array dtrace_probes[] but why not just use id = cur_value + 1, cur_value is a global variable to record the lastest id? Is this a trick? for what? Thanks :)

I am trying to use dtrace to trace all sscanf calls. I am able to use pid provider for this. But my application forks off children at times to handle requests. Is there a way I can stop the child process immediately after it is started so that I can attach a pid provider to that and trace the scanf calls in it? I have tried using the "create" probe but that did not help.

HI there, I?ve discovered DTrace few days ago and I?m currently stuck on a cpu stats problem. I?m trying to poll the cpu_t.cpu_acct[] array to pull idle, system and user values. So, I made this little script: ------------------------------------------------------------------------------------------------------ #!/usr/sbin/dtrace -s #pragma D option quiet this uint64_t start; this hrtime_t

hi, I am trying to find out the avg cpu time spent in each of my user methods (exclusive of other methods invoked by a method). Hence the following snippet failed miserably: ----------------------- pid$target:a.out::entry { time[probefunc] = timestamp;} pid$target:a.out::return { @spent[probefunc] = avg(timestamp - time[probefunc]);} END { printa(@spent);}

Dear all, please could you advise me on the following : I've written a R script that reads 3 arguments from the command line, i.e. : " args <- commandArgs(TRUE) TUMOR <- args[1] GERMLINE <- args[2] CHR <- args[3] ". when I submit the R script to a PBS HPC scheduler, I do the following (below), but ... I am getting an error message. (I am not posting the error message,

I''ve found what I think is a deadlock in the dtrace fork code. My only Solaris test machine is a single cpu box, where I have been unable to reproduce in the field so far. I''ve been able to reproduce on other platforms. Here is the scenario. You''ve got a target process, which has static probes. It is calling fork(), which causes it to end up at line 330 in fork.c:

Hi, I have changed directory ownership permissions recursively such that it is owned by username:groupname , where groupname is not the default group, i.e., username. However, when a user creates a new file the default permissions are again username:username. How can I give ownership permissions on a particular directory so that any files created in that directory will always have specifc

Hi, ?I am running Asterisk 1.4.21.2? on Fedora Core 2. Looks like The Asterisk Process dies after a few hours...I have full debugging turned on but file /var/log/asterisk/full does not show anything specifc..neither does var/log/messages.. dmesg also shows nothing specific to Asterisk dying/corring...Where does Asterisk dump core files if it cores..Any other pointers on where to look would be

Hi I read on LLVM blog that meta-data has been implemented to coney debug information to run-time system. Can one use meta-data to convey developer specifc hints to run-time system (e.g. JIT compiler)? Keen to know your thoughts on this.

i''m writing my own generator :) basically a custom scaffolding type thing to make my life easier when creating new resources. instead of doing something like script/generate custom_scaffold MyResource name:string description:string ... i decided to store all the metadata about the tables and fields in the db. my generator creates the model stub files when given a name that corresponds

This sounds like an operating system specific question, in that "submit the R script to a PBS HPC scheduler" would be the kind of action that would run R with very different environment variables and possibly different access credentials than your usual interactive terminal. A thorough reading of the "Installation and Administration Guide" and some study of your HPC

A lot of people in the security community, myself included, are interested in memory forensics these days. Virtualization is a natural fit with memory forensics because it allows one to get access to a guest's memory without having to introduce any extra software into the guest or otherwise interfere with it. Incident responders are particularly interested in getting memory dumps from

I don't see why not. I've used LLVM metadata to record type-inference information and to

Has anyone come across the above in 2.0.7 in a Solaris/Sunos environment. The result is that certain users cann't map drives. Thought it might be something specifc to this version and the user being a secondary member of a large group (not netgroups)... Then I checked the source and the parse_net.c is the same version.... Anyone.... TIA Gordon

Hello all, I am still reading about my QoS rules and I need that one of my servers (that is into my LAN but has an routing ip address) did not get into the qos rules I have. So I want that all traffic coming or going to that specifc host did not get shapped by any traffic control and do not get even into a QoS class. How can I do this? Att, Nataniel Klug

Hi, Is it possible to pick the context of a call from chan_sip based on the domain of the To: header of the INVUTE? I've had a quick look throught he code and can't see anything, I want to use the voicemail virtual hosting with chan_sip. Can the sip domain be picked out with a global in extensions.conf? This woud also solve my problem. If not is there any specifc reason/restriction

Hi, I am tracking down a problem and would like to know how I can follow a forked process with my dtrace script, or how I can trace a dynamic library. Here is the problem. I am tracing dtlogin, and specifically I am trying to determine what error libpkcs11`<routine> is returning. It turns out dtlogin forks a lot of processes, and I believe the second forked process is the one that winds
