we want to enhance the current libpcap version 1.1.x to provide timestamp in nanosecond resolution.
While searching related to same, we found that enhanced libpcap requires x64 architecture.
Is that so?
Do we need 64-bit architecture for using enhanced libpcap for nanosecond timestamping ?

I'm running Ubuntu 10.04.1 and am trying to get packet capturing working for my Bluetooth dongle using hcidump.From what I've read, libpcap must be compiled to enable Bluetooth sniffing and given that hcidump isn't finding a single packet, I'm guessing the version Ubuntu has installed for me isn't compiled with bluetooth support.So I downloaded a newer version of libpcap and installed the bluez header files. Configured libpcap and it gave a "Yes" for bluetooth support. It is now installed and sitting in /usr/local/lib/. Now I'm trying to compile hcidump to use this lib rather than the system default but I can't figure out how...I've read that GCC can be passed the -lpcap flag to set the path but I haven't figured out how to do this.

One of my clients needs a backup of his svn repository. I see that this is possible using svadmin dump command. I see where the location of the source repository is, but I don't see anything in documentation as to where the actual dump file is located. I need to know where the dump file is so I can scp or rsync the file to another server for backup.

the function terminates if no key is pressed for 10 consecutive seconds. I tried using the -t option as suggested in some forums, but my version of showkey doesn't have the option of changing the timeout. The options I get are:
-h --helpdisplay this help text
-a --asciidisplay the decimal/octal/hex values of the keys
-s --scancodesdisplay only the raw scan-codes
-k --keycodesdisplay only the interpreted keycodes (default).
Is it possible to write a script to use this function and still keep the function active until an interrupt is recieved?

I am running slackware-current and I have tcpdump-4.1.1-i486-1.txz installed. If I remember right libpcap used to be part of tcpdump, but since recently i cannot find it in my system anymore! Tools like nmap give me the error message:
"error while loading shared libraries: libpcap.so.1: cannot open shared object file: No such file or directory"

I am trying to install libpcap and tcpdump, but even if I have already installed Flex, as the terminal tells me to do. What else could I do?
Code:
configure: error: Your operating system's lex is insufficient to compile libpcap. Flex is a lex replacement that has many advantages, including being able to compile libpcap. For more information, see [URL].

I am running Ubuntu Hardy Heron. Trying to configure a ax25 packet software to connect to the internet by way of a port called tun0 that I've created within the software. I can connect within the LAN but not outside. If I execute tcpdump while the tun0 is up, I first receive the message, "WARNING: arptype 65534 not supported by libpcap - falling back to cooked socket."Question: Does this warning relate to my connectivity issue and if so, how can I 'fix' the problem?

I am trying to install libpcap version 1 on my centos 5.5 (which supply libpcap 0.9.4 as built in). I need libpcap>=1.0 to install snort 2.9. I tried to install by downloading source code from tcpdump.org but failed to update libpcap-0.9.4 by libpcap-1.0.0.

For compiling ArpON on my server the cmake command says 'libpcap not found' when a newer version libpcap-1.0.0-5.20091201git117cb5.fc13.i686.rpm is already exiting which I am unable to erase as other rpms depend on it.

I am doing some Linux kernel programming for my research project. I need to record the timestamp (by using cpuid and rdtsc) when an interrupt handler (top half) is first invoked. Due to the time critical nature of the problem itself, I have to do the timestamping inside the interrupt handler itself (the first operation when the handler is called). However, I understand that tasks that are not so time critical should be deferred to a tasklet function (bottom half) for processing because other interrupts are disabled in a (top-half) interrupt handler. I am currently out of idea on how I can pass the timestamp information that I have obtained in the interrupt handler to the corresponding tasklet function.

I'm currently using OpenSuse 11.1 web server. This is bad since 11.1 is no longer supported. the reason why I am using it is because Function set_magic_quotes_runtime() was no longer being used. (so I was told)
That being said, is there a way to get Function set_magic_quotes_runtime() to function on the newer versions of OpenSuSE?

I looked on the net for such function or example and didin't find anything, thus after having made one i guess it would be legitimate to drop it to see what others thinks of it.

local arrayname=$1

I am developing a function say my_abc() which does the same thing as kernel function abc(). Now I want that instead of using predefined kernel function kernel starts using my function. It might be possible that the kernel function has been used so many places.

If you set or export an environment variable in bash, you can unset it. If you set an alias in bash, you can unalias it. But there doesn't seem to be an unfunction.
Consider this (trivial) bash function, for example, set in a .bash_aliases file and read at shell initialization.
function foo () { echo "bar" ; }
How can I clear this function definition from my current shell? (Changing the initialization files or restarting the shell doesn't count.)

I've got a sticky little problem with a bash script. Please consider the following code:
Code:
#! /bin/bash
processArgs() {
echo "Count = $#"
while [[ $# -ne 0 ]]; do
echo $1
shift
done
}
processArgs $* If I call this script with Code: ./script first second third it'll print each of the argument on a new line - exactly what I would expect. However if I call it with
Code: ./script "Single Argument" "Second-Argument" it splits the first argument in two using the space as a delimitor. The problem appears to be the call to processArgs, where $* doesn't honour the quotes around the variables sent to the script.

I'd like a function in my .bashrc file that would allow me to pass text to it and echo the text to a specified file. I know it's simple as "echo 'text' >> file," but ideally, I would want to alias the function so I execute something like:
Code:
user~ $ write 'this is a test' with "write" being the function, and 'this is a test' being echoed to the file. I hope I explained that well enough.

What i want to do is create multiple informix sql statements & later run them via a bash script.
Here is what i have so far (this works) but is meant to be run from a cron job so it only does one day at a time:
echo "
update hst`date --date='yesterday' +%m%d%y`
set x = 'GARP'
where y in ('CRE', 'LAC', 'SRL', 'JAG', 'JNM', 'BIM')
and appl = '';
[Code].....
The problem here is it doesnt want to read the variable $x correctly so the statement fails.

I had a dream least night in which I was on my computer and I was typing the command Netstat -a in command prompt in Ms-Dos. And I was wondering why it looks so much like a Linux terminal command? This question persisted in my mind after I woke up. So what is the story about it?
