i'm trying to get several strings from a single string, separated by comma's.there are comma's that do not separate strings, however, those enclosed in parantheses.an example would be:vt, word1, (word2, word3)word4
exploding by ',' would result in:
[0]=>vt
[1]=>word1

This is my main question:Quote: In raw socket sniffing: how do I copy data from a structure into a char[] or pointer? My problem: I started doing some raw socket programming in OpenWRT (I'm a newbie) for research. It's been a long time since the last time I programmed in C, so here's my newbie question/problem.
I'm receiving packets and using an .h file with the structures to get the information of each 802.11 packet in monitor mode (attached to this post).My (simple) goal is to get the Tx MAC Address. No luck. This is my "read the prism header" function:
Code:
ParsePrismHeader(unsigned char *packet,int len)
{
wlan_header *wlan;ieee_802_11_header *i802;u_int16_t eth_type;
unsigned char *mac;unsigned char *mac2;
wlan = (wlan_header *)packet;
i802 = (ieee_802_11_header *)(packet + wlan->msglen);

I'm trying to compose a line of numbers each single digit taken from a variable eg: 1010001 each variable digit is either a 0 or 1 made from variable layer1 through 7. I need to add each layer variable to the last to compose the number with no commas or spaces and add it directly after the -p option in the show_command line. I used array and list and the commas mess up the command and inserting "pens" in the show command interpertes it literally instead of the list or array value? The insert should look something like 1000110

The default installation of 11.3 has ipv6 enabled.When accessing a site using any browser, there was a considerable delay before the page would appear.I disabled ipv6 and things are normal.Is my computer going to explode in a couple of months from all the backed up addresses? Seriously, Is there something wrong with my setup?Why would ip6 be enabled by default if it slows things way down?There are just so many things I don't know.

I want to extract only the strings after the comma,
I have a fairly long list of data that I am trying to put into a math program (maple) but before I can do that I need to edit the format of the data such that at the end of every 25th line I add a comma. I would prefer a solution that uses vi, but if that's impossible sed would be fine also (or awk).

need to monitor pecific processes over a time frame in terms of the amount of memory and cpu usage it utilizes. I can do this using the top -p <pid> option and using ps to retrieve the pid's. However, seeing that the pid's might differ and it needs to be run on about 13 different machines, I would like to write a script for this that can be run at set intervals. My problem that I have is this:
- When running top -p <pid> I can specify a comma seperated list of the processes required to monitor at that specific time.
- I can use ps -ef | grep <process> | grep -v grep| awk '{ print $2 }' to retrive the list of pid's and output this to a file.
However, how can I output these to the file as a comma seperated list without having to manually do this every time? The reason for this is (an example), lets say I want to monitor the cpu and memory usage of postgresql as well as all its child processes, then I would ps grep for postgres and get the list of pid's for instance.This list then needs to be passed to top -p as a comma seperated list of pid's I suspect that awk or sed might have some options available for this but I do not know this well enough.

I have a CSV file that's created in an application that can't output lines longer than 250 characters. the data fields, all together, are longer than this. how would I remove the line break from every line that ends with a comma? For example:

I am using Ubuntu 9.10 in U.S. English with a German keyboard layout. Accordingly, pressing the delete button on the numeric keypad will produce a comma, which most applications do not recognize as a decimal. in order to have the key produce a period.
I have tried editing the /usr/share/X11/xkb/symbols/de and changing the line
Code:
include "kpdl(comma)"
in the "basic" section of the file to
Code:
include "kpdl(period)"
which seemed like the perfect solution, but upon restarting an error message pops up and the keyboard layout is changed to U.S. English.
Code:
cd /usr/share/X11/xkb/symbols
xkbcomp -lhlpR '*' -o ../symbols.dir
which does nothing at all if used with sudo and produces an error message if used without. Reverting changes to /usr/share/X11/xkb/symbols/de removes all errors.
Is there something else I need to do to have xkb accept my changes to the file?
Code:
include "kpdl(comma)"
does not specify a symbol to be mapped to the keypad delete key, but rather constitutes a command that integrates a pre-specified option into the layout file. Thus, simply removing the line works perfectly well, even without using the above suggestion to register the change to the file with xkb (or whatever it does).

So I have several questions:
1. Should I learn JOGL or start learning C++ and do C++ openGL programming?
2. Is there a big difference between JOGL and C++ openGL programming?
3. Is it worth to learn openGL? Does it have a future?
4. Is it a big difference between openGL and directX coding?
5. If choosing Java, then JOGL or LWJGL?
Why and what is the main difference between them?

A simple TCP based chat server could allow users to use any TCP client (telnet, for example) to communicate with each other. For this question you should consider a single process, single thread server that can support exactly 2 clients at once, the server simply forwards whatever is sent from one client to the other (in both directions). Your server must not insist on any specific ordering of messages as soon as something is sent from one client it is immediately forwarded to the other client. As soon as either client terminates the connection the server can exit

I need to know what, for example, 'ttable' means and what is its syntax. This seems to be a state secret.
We have documents on multiple workstations and want to collate them into a single repository to provide text search and download. So far we have implemented rsync to copy files from each workstation under a directory for each workstation on a server (incidentally providing a backup) and have set up text search using Xapian with Omega; users access it via a web browser. Still to do is to set up a system to copy files from each workstation's area on the server to the repository.
Many files are duplicated. In these cases we want to preserve the names but keep a single copy of the file;hard links can be used for that.For each file to be copied from a workstation's area into the collated area we need to check whether it is a duplicate (file size and, if same, MD5 sum) and if so, create a hard link to the original rather than create a copy.A system to detect and replace duplicates in the collated area has been written using ruby and postgresql but the developer cannot commit to continuing this work. It does mean we have a postgresql database populated with "fingerprints" of files in the collated area.My first priority is to get the system working; in the longer term whatever is developed must be maintainable; I do not yet know which language skills are available locally.
I am fluent in bash and competent with awk. Ruby looks nice but I have started to learn python and do think it prudent to learn both at the same time. Python's postgresql capabilities are not settled but may be fine for the simple usage required.What to do? A bash solution would run very slowly but could be developed quickly. Language knowledge aside, I have found it difficult to install ruby on the server (CentOS 5.5;installed rvm but "gem" still not installed; seems a very complex system with its own package management).
