Red Hat :: RHEL6 X64 Client Closed-Source Software

Nov 13, 2010

I would like to play .mp3 and .mpeg files with Red Hat Enterprise Linux 6 Client. Flash and Java must also be working. For Java, I have download the jre-6u22 and the jdk-6u22 and installed manually. How can I get automatically updates for them? For Flash, I have installed the i386 package and the .repo so the updates must working. So, I have

[URL] hasn't RHEL6 yet.

Enabled are only Adobe, RHEL Client v6 for 64-bit x86_64 and the RHEL 6Client - RPMforge -dag repositories. The others make problems with dependencys. RPM Fusion has no EL 6 repos, so I deactivate them. I have chosed to install the gstreamer plug-ins bad but haven't find them. Manually download from rpmfind or pbone results with wrong's horrible.

Programming :: Detect A Closed Tcp Client Connection When Client Is Only Receiving Data ?

Mar 9, 2011

I am writing a TCP server in C, and the server listens to incoming client connections and accepts them. It then creates a thread to handle the client. The clients are expected to only receive data from my server and not send any data. So if I use a select() call with a recv(), I believe that the recv() will just block forever since there will not be any data coming from the client. If I use a non-blocking recv(), then this will just return a 0 which tells me nothing because the client is not expected to send any data. I am not sure if I have misunderstood some socket concepts, but I need a solution to detect when the client has disconnected so that I can close the socket and stop sending data to the client. As I understand it, simple ACKs etc are not captured by the recv(), and only data sent by the client will cause recv() to return a non-zero value, so I am not sure how to know when the client has disconnected.

Programming :: Create Commercial(closed Source) Softwares?

Mar 18, 2010

I'm asked to create a network tool in C and a GUI API in linux platform by my company. I'm aware of the GPL & GLPL licenses , but not clear whether I can create a proprietary commercial software with the tools & libraries available in Linux: My tool will be written in C and will be using the some network library functions in the Linux and some header files .(Their license is GPL) , also the GUI i'm planning to develop is using GTK and Glade / Anjuta, (GTK is based on GLPL license) , I will be using GCC compiler for C programs,

Please let me know whether it is possible to create a closed source-commercial software using the above tools/libraries, if not possible is there any workaround is there for creating commerical tools in linux Can I make some part of my code closed and some parts open? Also please let me know which is the best GUI building programming language/IDE that can be used with C programs in linux

Programming :: How Could Server Detect Closed Client Socket Using TCP And C++

Aug 6, 2010

Reading some examples on net and copying some codes I was able to build a (frankstein) server that accept connection from one client and receive and send messages to it. The big problem that shows up is that I don't know when client disconnects from my server.

I've been looking for a solution, but no success. I'd read about SO_KEEPALIVE option (which could solve my problem), but I don't know how to use it (how to check the value of it).

I can't use ping because the server (machine) could be running, but not the client (software).

Anyone knows a good tutorial or how to (for beginners like me xD) of TcpIp sockets using c/c++ and how to detect when a client disconnect?

I don't know sockets very well.

Ubuntu Networking :: Set Up Dedicated Server For Source Games - Port Closed?

Jun 23, 2011

I am currently having an issue attempting to set up a dedicated server for source games (TF2, CS:S, L4D2). The required port (27015), along with most others, appears closed to the rest of the world and upon a port scan with DMZ hosting on (therefore no router interference between the internet and my computer) only a few ports are open (80, 139, 443, 445). My ISP does not block ports so therefore the only issue I can find is with my computer running Ubuntu 11.04. I have ensured that all traffic is allowed via iptables and I can't think of anything else that would have ports closed.

Red Hat / Fedora :: How To Install RHEL6 Via PXE Boot

I have an RHEL 6 image on one machine and on the same machine I also have a DHCP server ( but am not sure if I have a TFTP server as well - anyway to check ?)What I need:

I need to install RHEL 6 on another machine using the image on the earlier mentioned machine. I have come across many links on my searches online which cover the theoritical aspects which mentions the use of "kickstart" file which once transfered to my client-machine has to be run to install RHEL on my client.. But my problem is, I am unable to find any place which gives a sequence of steps or commands to follow which will help me install this... Can you please guide on how i can go about this

Red Hat :: RHEL6 Have Ia32-libs (or Equivalent)?

Feb 10, 2011

I recently upgraded my RHEL system from 5.5 to 6.0. When I went to install a 32-bit application I got the normal failure for missing 32-bit libs (/lib/ bad ELF interpreter: No such file or directory). With RHEL5, simply installing ia32-libs takes care of this problem.

In this case, a "yum search ia32-libs" shows no such package exits. So either it doesn't exist or I've got a yum config problem (although I can pull x86_64 packages just fine). If it doesn't exist, is there an equivalent package?
