what is the best/accurate way to get the process id in java code in order to write to the log file. To be specific: I am using avalon logkit for logging. I really cannot find a way to write the process id to each line in the log.
View 1 Repliesi want a process that can operate as both a TCP echo server and a UDP echo server. The process can provide service to many clients at the same time, but involves a single process that does not start up any other threads.

Linux: Is there something similar to "top" for I/O?
I am trying to do some CPU intensive operation on a Linux machine and it is showing very high load.
I want to figure out if this load is due to I/O or CPU usage. How could I get the percentage of I/O usage by process?

View 2 Replies View RelatedA 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

View 2 Replies View RelatedThere are C, C++, Java, Perl, Python, PHP, and some other programming orand scripting languages for a Unix / Linux Distro. On a scale of 1 - 10, I rate myself on:
5 for C / C++
5 for Java
7 for PHP
2 for Perl
When I look for a Unix job I am often asked if I know C / C++, Perl or Java. Well, they mostly look for C / C++ + Unix or Perl / Python + Unix or Java + Unix combinations. That is the trend here in India. When they advertise for C / C++ + Unix they also mean Real Time System, Kernel (Modules), and Device Drivers Development. I don't know how to do those things in C / C++. But I must say that I love C / C++ and anything else no matter how attractive or easy it could be doesn't look that much challenging to me. So, which should I take now to add to my skills set and be more productive in terms of System Administration and Application Development and Support?
In C/C++ and Java, though I know them, I don't get to work in my current job. However, I often use Shell Script (Bash) and PHP and so I am finding Perl easy because the basics of Computer Programming that I learnt by learning C and C++ and Java have made it easy for me to understand any programming language.

I have a few questions regarding HTML, UNIX and Javascript. I've been tasked with creating a fairly simple webpage that takes a few inputs. Each input must correspond to an argument in a UNIX command running on a server.On a UNIX server we have a script (.ksh) that takes 3 arguments. The result of the script is a data file which is FTP'ed to an external server. Let's forget about the FTP portion for now. I would like to know where I should begin.What I know so far:
1) I will need HTML to create the webpage. Skill level is high
2) I will need Javascript to make my webpage more interactive. Skill level is high.
3) I will need to understand the UNIX environment. Skill level is high.
currently I've got a big problem on programming with sockets. I use the winsock2 API and want to receive data from a multicast adress running on a UNIX-PC. The connection works fine and I really receive data from this group, but as it seems not the right packages. The received data is saved in a char[]. E.g. at received_msg[12] is a float value. This one I would like to read out, convert and use it in later progress the next value is y at received_msg[16]. The same Code works on a Unix PC with unix sockets but converted to winsock I've got the described problem and I have to make this code work under windows.
Here a piece of the code (received_msg[12]='3f'):
Buffer is a struct containing the two float values x and y. If I convert the char as this under windows the value of x is a huge number. The correct value is around 192, so receveid_message[12] should be 1.92. Could it be that the Unix-PC is sending data in an other way than the winsock receive it?
