I'm trying to modify the code for gblink so that it can read from my usb to parallel port cable. I know that the address for a normal parallel port (/dev/lp0) is 0x3bc, but how can I find out the address for /dev/usb/lp0?

I read that xinetd listens on the service port and passes incoming traffic to the service (ftpd) via stdin. However, the ftpd source code reads its input from a socket not from stdin.
Am I to conclude that in order to be managed by xinetd, the source code for ftpd (or telnetd etc..) must be modified or recompiled to take its input from stdin??

View 5 Replies View RelatedFor my work, I have to modify the routing lookup process at Linux kernel.
The details is below:
A-----B.
We have pcA, pcB (using Linux OS kernel 2.6.26.5) connect together. We need to modify the source code of kernel at B in order to if A sends the packets with destination IP address as C, pcB still receives this packet and send to transport layer (that means, it bypass the routing lookup process at kernel).
The solution I used as the following code...
Now we are implementing our own shell using C++. What upseting us is the history command function, we use an array to store the history commands, and print the when receiving the up and down arrow buttons. The problem is we cannot modify the history command already printed on the terminal, we even cannot move the cursur, let alone modifying the command.
Okay so I'm working on a program here as I'm learning java,I have an array that is initialized with 5 objects that are hard coded. I have made a GUI that takes the input needed and creates an object with those values.I need to add that object to the ArrayList that I have previously made.Okay, so I have three classes, guiclass.java, main.java and gladiator.java Objects are made and defined in "gladiator".Main contains my public static void main section, launches my gui, creates my five hard coded objects, creates my ArrayList and adds my five hard coded objects to the ArrayList.Now, I need to add the object that I generated in the guiSection [action Listener]to the ArrayList that I created in my main class's public static void main string... section. Problem is my arraylist "cannot be resolved" from guiclass.
View 13 Replies View RelatedI have a CDL netlist with 5630 lines. 512 of the lines are over 128 characters. The tool I am using to read in the CDL returns an error for each line over 128 characters.
If the line is too long I can fix it by adding a line continuation symbol, in this case a "/", somewhere prior to the 128th character then a line feed, obviously, and a "+" to the continuation.
example (pretend its a long line);
before;
this line is too long
after;
this line /
+ is too long
Part of the problem is that I can't use a constant point prior to the 128th character because I can't break up a term.
bad;
this line i /
+ s too long
If I can replace the last space before the 128th character with " / + " on all lines that are over 128 characters then I'm golden. I'm not sure if I need to escape the + or not. If so then the substitution is " / + ". And if I use sed then I'll escape the .

View 1 Replies View RelatedI'm running RHEL5.5 and nagios 3.2.0. The real question deals with how to change the printed output so nagios will work with it.I have made a script that will calculate network throughput on interfaces. The script is going through and finding all interfaces (eth, bond, lan) and doing the math to calculate throughput.The output is mainly for nagios to report and trend the values. As nagios wants to see nothing but perf data after the '|' character, I somehow need to have only one '|' character for all of the output.

There is a file with that format of each models' information.I don't think that's good format, but I cannot change that format. I needed to modify the model name, 'model = xxx' as 'model = abc'.And I don't know how to parse and modify 'model = iii' and 'model = ddd'.The only clue to parse 'model = ddd' is the second 'model = ' after the second 'system information'. But how to parse the second keyword?Is it possible with 'sed'?I sometimes have to modify the information of the file.using shell script if possible.Python is ok. (Shell script is better for me.)
View 15 Replies View RelatedI wanna learn how to store data in text file and be able to modify it and save as well using C++.
Note: im using Turbo C++ 3.0
I want my bash file to read from "input.dat" the two values emin emax. My input file looks like that:
#cat input.dat
!Energies
emin 10.00 !minimum energy
emax 30.00 !maximum energy
Now this seems to be not so hard with the command awk
#!/bin/bash
awk '{FS=" "}/emin/{print $2}' input.dat
awk '{FS=" "}/emax/{print $2}' input.dat
[code]....
So far so good. Now, I want to define two variables (e.g. e1,e2) in the bash file, so that their values would correspond to 00.00 and 30.00, as read from the input file. This one I have not found yet, thus asking for your advice. At the end, writing echo $e1 $e2, I should get 10.00 30.00 This is even harder to me: I want to replace the values emin,emax in a new file "modify.dat" which looks like that:
...
c---- energy interval
emin = 1.00
emax = 2.00
...
with the values e1 and e2 I have in my bash file. In other words, I want to call "modify.dat", find these two lines and replace the numeric values with the e1 and e2. At the end, my file should be like:
...
c---- energy interval
emin = 10.00
emax = 30.00
...
As awk programmers may know, we can print range of lines with awk, from an initial pattern until a final pattern as follow:
Code:
awk '/Initial_String/,/Final_String/' inputfile
Well, I have this inputfile:
Code:

Once having those elements in that way within an array(a[]), I want to be able to manipulate the array (a[]) and copy its elements

Only inserting the missing "array" coding and based and follow the code I've written Not needed to create a new code to do it with other method.
I am working on a project with a lot of vector math and I'd like to find a way to speed it up.eading about SSE, but I've found no explanation on how to actually use it in code (was looking for some kind of hello-world example, complete with compilation instructions).Does the gcc compiler automatically make use of SSE, if you add the -sse(2,3) option on the command line? Or are their specific functions/libraries you need to call?
View 12 Replies View RelatedIs there, by chance, a fancy name to describe code that must be in a program but will never be executed? In one of my (Haskell) programs, I have some error-handling code that must be in the program to keep the compiler happy (due to the type checking). However I know that, due to the logical structure of the program, it is impossible for the code to be evaluated. I am curious if there is a technical name given to code that must exist but cannot be executed.
