ubuntu-12.04

I am trying and using OpenSSL in C (on ubuntu 12.04). Took an example from here . Everything goes well until BIO_do_connect() which returns a negative value. Probably I did something wrong in calling these two API because bio is passed to BIO_do_connect(). An example of the format to use in the second parameters of these two functions would be appreciated. BIO_set_conn_ip(bio, &ip); BIO_set_conn_int_port(bio, &port); It is really not comfortable that both functions return 1 always (correct, wrong or anything), as stated here . Here the full code: int main(void) { BIO * bio; SSL * ssl; SSL_CTX

I want to use low port in my application (SNMP Trap Receiver on Spring web + Tomcat7). As I told in this thread Binding Low Port to Java Program on Ubuntu Server , before, I got error Permission denied. Then I change tomcat7 user group be root. But after that, I got java.net.BindException: Cannot assign requested address error. For every port that I try (low or high port), I always got this error. I check if the port has used, I see that the port still free. I check my /etc/host content, it is like this: 127.0.0.1 localhost 127.0.1.1 test-server # The following lines are desirable for IPv6

I make simple program in C which uses glib.h , but when I compile it I get an error like: $ gcc test.c -o test test.c:3:18: fatal error: glib.h: No such file or directory compilation terminated. So from above it seems gcc can't find glib.h file (which is a part of the libglib2.0-dev package and have already installed it). So first I try locate glib.h files in my system and found output as below: $ locate glib.h /usr/src/linux-headers-3.2.0-29-generic-pae/include/config/blk/dev/bsglib.h /usr/src/linux-headers-3.2.0-48-generic-pae/include/config/blk/dev/bsglib.h /usr/src/linux-headers-3.2.0-57

I've been learning sqlite3 programming in C++ for the first time and this error confounds me and my internet searching abilities. Here is my code, as far as it gets before throwing an error. #include <iostream> #include <sqlite3ext.h> using namespace std; int main() { sqlite3 *database; int check; check = sqlite3_open("introdb3.db", &database); //error is here } I'm pretty sure that it has something to do with the libraries that are (or aren't) being linked, but I can't figure out how to make it go properly. I'm on Ubuntu using code::blocks. Thanks!! Instead of #include <sqlite3ext.h> write

I am trying to use the multiprocessing package to call a function (let's call it myfunc ) in parallel, specifically using pool.map i.e. pool.map(myfunc, myarglist) . When I simply loop over myarglist without using multiprocessing there are no errors, which should be the case because all operations in myfunc are called within a try block. However, when I call the function using pool.map the script invariably stops running, i.e. it stop printing a "myfunc done!" statement within my function and the processes stop using the CPUs, but it never returns resultlist . I am running python 2.7 from the
