Programming :: C/C++: Broadcast Receives No Answer - Can't Find Right Answer

May 18, 2010

How can I set the outgoing port for the socket? In wireshark, my outgoing port is 1024, and i want to set it to 6800 (or a similar port) I see the outgoing broadcast-message in wireshark, but no answer. There are three ECU's in the LAN, which should answer. The following code is a mixture of C/C++ and jointed from different articles:


In wireshark I can only see the outgoing message. But the "recvBuffer" (in the lower part of the code) contains the same content as the sendBuffer. Is it right, that I need a sender and further more a receiver? Or should I receive the broadcast-answer on the same socket on which I send the bc?

Server :: Getting Modem To Answer On The Correct Ring

Aug 2, 2010

I am having issues getting the modem it the dial-in server I have set up to answer on the correct ring. I have the /etc/inittab set:

Code: S1:2345:respawn:/sbin/mgetty -n 7 -x 6 -D ttyS2 yet I have to play with 'init q' and minicom to get it to answer on ring 7. Then a reboot destroys the setting and I have to go through the whole hassle again and it goes back to answering on the first ring.

This is not acceptable. This dial-in server is only a very back door into my network. It is only turned on when needed. Most of the time it is not powered up. When it is turned on it is by a non-tech person with out the ability to jump through the hoops to get it to answer on the correct ring.

Ideally I want this modem to just listen to the line after it stops ringing to check for a data signal and if it does not find it just hang up. If it finds a data signal then establish a connection and all that. That way it does not interfere with answering machine on the line. Google has yielded very little info about setting up dial-in servers. Modems are not used very much any more.

Server :: Login Incorrect Even After Giving The Correct Password?

Aug 3, 2010

One of my servers is displaying the error as login incorrect even after giving the correct password. Once I restarted the Virtual Machine and after that it is accepting the same password to login. I am not able to find out the problem, why the server is not able to validate the password until the virtual machine gets rebooted.

Programming :: Getting Closer To The Answer - Python Iterations Over Nested Tuples?

May 22, 2010

tupe=("File",("Open","Open a file"),"Edit",("Cut","Cut a file"),("Paste","Paste a file"),"About",("About","About the program"))
for items in tupe:
if type(items)==str:


I'm trying to understand how to make "File" be the parent information for "Open","Open a file" and "Edit" to be the parent of "Cut, Cut a file" and "Paste", "paste a file". Does anyone have a suggestion for accessing the a nested tuple in this manner? The above code does not quite do what I want it to. The above code is for visual purposes, but I'm learning how to refactor for wx.python.

Programming ::make AWK Do *something* Without Giving It Any Stdin Nor Inputfile?

Oct 10, 2010


I've given the output from `df` on AWK's stdin. But what I wonder is if there's a way to get AWK to run `df` itself, produce the same output, and exit? Doesn't seem to be that simple. Here's some examples: Works for some reason, and I think only in Bash (nothing is required in the $()


does AWK absolutely need *something* on stdin, before it begins to process the data? Can it be made to open a file or stream internally, act upon that as though it were the stdin, and exit?

Programming :: Expect/TCL - Unable To Get The Correct Results

Feb 8, 2011

I'll post the entire code here, and then specifically highlight what is just failing in a fashion I'm apparently incapable of fixing a few hours later:


# The script should be called with a file in the directory called sshServerList
# That file has the following format:
# Line # | Contents of line


I've had all kinds of different results and problems, but I've never been able to successfully log into multiple servers, though the first server in the list most times works okay (though might not on this iteration). I'm a bit hack and slash and I would be very greatful not only for a solution, but any tips on how I should have done this and places where I could clean up my code.

Programming :: Bash Script To Correct The Filenames

Apr 11, 2011

I have a directory that has a bunch of files and directories under it that I need to correct the filenames of. In fact, I plan on running this as a cronjob to keep checking filenames for certain characters. I want directories and filenames with spaces or pluses (+) to have those certain characters replaced with underscores (_). I know that this will involve sed but I'm not sure what else. A simple shell script would handle it.

Programming :: Not Getting Right Output To Correct Terminal Window

Jun 17, 2010

I have a server client prog in which server is my 'agent' and client is 'manager'. Following is the code for both agent and manager. I want my agent to send what manager is requesting. But it is not working the way I want. The parameters which manager is requesting, agent has to send to manager but in this program result for those parameters is shown on agent's own terminal window. Where as I want them on manager's window. Secondly, there result is not correct, means it is giving ' 0 K ram and 0 no of process....

Programming :: Sudoku - Calculate The Correct Box For A Given Square?

Apr 8, 2011

Im doing a sudoku-solver as a school assigment in Java. It is supposed to solve both 6x6, 9x9 and 12x12 boards.Im pretty much done with my algorithm(brute force), but I'm having a hard time figuring out how to calculate the right Box for a Square. I found this snippet:


// calculate BoardPos for index, where index is 0..80
void loadBoardPosFromIndex(BoardPos &pos, int index) {
pos.index = index;


This works on 9x9 boards, but I really dont get the math behind this, and how I can create a generic rule for both 6x6, 9x9 and 12x12 boards.

Programming :: GDB Doesn't Provide The Correct Line In The Source Code

Jan 23, 2011

I found a strange problem when I use gdb in eclipse to debug. When I step in the program, the register RIP(I'm using x86_64 machine and that's EIP in 32 bit mode) shows correctly but the line stepping in the source code may be far from the correct line. For example, when there is no loop in the source code, the RIP keeps on increasing and the current instruction pointer goes back to several lines back. I'm sure the source code is the right one because I when I checked the memory and local variables after several lines the values are all correct. The source code has many empty lines and does it matters with GDB?

The only thing I need to add to it is a "check to make sure the user running the script is in the /tmp directory".
