You can find Linux clients for several file-sharing networks. Taking into account how many clients are available for each, the current top three peer-to-peer (P2P) networks are eDonkey2000, FastTrack (derived from Kazaa), and Gnutella. Here are some desktop applications that allow you to become a full-fledged file sharer.
Hello folks,
I was guessing if there is a way for configuring Radius authorization on Linux clients. My meaning is to make Radius server manage the authorization/permissions when executing any commnand on my linux servers.
Then, there's any way to configure this with Radius? can I also... (1 Reply)
VIO Server is managing both AIX Clients and Linux Clients. For AIX Clients, we could do a disk mapping from slot numbers to VIO and also uname -L to determine the lparid and serial number frame its running on.
From a Linux Client,
How do I know which IBM frame its running on? Any command to... (4 Replies)
Hi guys.
What would you recommend me a software running on Windows, and it is capable for backing up Windows and Linux (unix is optional) machines?
The application should have following features:
- Encryption.
- Authentication
- Open source if possible :)

Hi there,
I am wondering if by logging in to a unix system, if it is possible to get the IP address of the machine I am connecting FROM.
I know how I can do this using the name server, but is this possible without a host lookup?:confused:
Thanks,

tcp - Internet Transmission Control Protocol
Syntax
#include <sys/socket.h>
#include <netinet/in.h>
s = socket(AF_INET, SOCK_STREAM, 0);
Description
The TCP protocol provides reliable, flow-controlled, two-way transmission of data. It is a byte-stream protocol used to support the
SOCK_STREAM abstraction. TCP uses the standard Internet address format and, in addition, provides a per-host collection of ``port
addresses''. Thus, each address is composed of an Internet address specifying the host and network, with a specific TCP port on the host
identifying the peer entity.
Sockets utilizing the TCP protocol are either ``active'' or ``passive''. Active sockets initiate connections to passive sockets. By
default TCP sockets are created active; to create a passive socket the system call must be used after binding the socket with the system
call. Only passive sockets can use the call to accept incoming connections. Only active sockets can use the call to initiate connections.
Passive sockets can ``underspecify'' their location to match incoming connection requests from multiple networks. This technique, termed
``wildcard addressing'', allows a single server to provide service to clients on multiple networks. To create a socket that listens on all
networks, the Internet address INADDR_ANY must be bound. The TCP port can still be specified at this time. If the port is not specified,
the system will assign one. Once a connection has been established, the socket's address is fixed by the peer entity's location. The
address assigned the socket is the address associated with the network interface through which packets are being transmitted and received.
Normally, this address corresponds to the peer entity's network.
TCP supports one socket option that is set with and tested with Under most circumstances, TCP sends data when it is presented; when out-
standing data has not yet been acknowledged, it gathers small amounts of output to be sent in a single packet, once an acknowledgement is
received. For a small number of clients, such as window systems that send a stream of mouse events that receive no replies, this packeti-
zation may cause significant delays. Therefore, TCP provides a Boolean option, TCP_NODELAY (from to defeat this algorithm. The option
level for the call is the protocol number for TCP, available from
Diagnostics
A socket operation may fail with one of the following errors returned:
[EISCONN] Try to establish a connection on a socket which already has one.
[ENOBUFS] The system runs out of memory for an internal data structure.
[ETIMEDOUT] A connection was dropped due to excessive retransmissions.
[ECONNRESET] The remote peer forces the connection to be closed.
[ECONNREFUSED] The remote peer actively refuses connection establishment (usually because no process is listening to the port).
[EADDRINUSE] An attempt is made to create a socket with a port that has already been allocated.
[EADDRNOTAVAIL] An attempt is made to create a socket with a network address for which no network interface exists.
