C++ Sockets 2.2.7 (Default branch)
C++ Sockets is a cross-platform C++ wrapper for BSD-style sockets. It implements the TCP, UDP, ICMP, and SCTP transport layer protocols. Implemented application layer protocols are HTTP/HTTPS (using OpenSSL), SMTP (server), and Ajp/1.3 (server). Features include transparent SOCKS4 client support and asynchronous DNS. Included in the library are a number of HTTP client functions such as GET/PUT/POST, and also Web server framework components. License: GNU General Public License (GPL) Changes:
HTTP header names are no longer converted to lowercase. "setsockopt()" wrapper methods returning int values have been fixed. The query_string attribute of HttpRequest is no longer set when there is no query string present.Image

Help with sockets in C

if i have a server which wants to connect to exactly 5 clients, does that mean i need 5 socket file descriptors and use listen(socket_fd,1); for each one or just do listen(socket_fd,5) also whats the second parameter number mean? what happens if i put 0 there? also if i am connected... (28 Replies)

ipgrab

IPGRAB(8)						      System Manager's Manual							 IPGRAB(8)

NAME

       ipgrab - A Verbose Packet Sniffer

SYNOPSIS

       ipgrab [ -ablmnPprTtwx ] [ -c cnt ] [ -i if ] [ expr ]

DESCRIPTION

       ipgrab  reads  and parses packets from the link layer through the application layer, dumping explicit header information along the way.	It
       is a lot like tcpdump except that it prints almost every header field.

   Options
       -a     Do not display application layer data.

       -b     Buffer standard output. Useful when you're redirecting output to a file.

       -c cnt, --count cnt
	      Terminate after receiving cnt packets.

       -C proto, --CCP proto
	      Assume a particular CCP protocol, such as MPPC. MPPC is the only one supported as yet.

       -d     Dump extra padding in packets. For example, according to an IP header, the packet ends at a certain point, but the  link	layer  may
	      have padded it beyond that. This option displays the padding. Not valid in minimal mode.

       -h, --help
	      Display usage screen with a brief description of the command line options.

       -i if, --interface if
	      Makes ipgrab listen to packets on interface if, e.g., eth0. If this option is not used, the default interface will be assumed.

       -l     Don't  display  link-layer  headers.  The  following protocols are considered to be link layer: ARP, CHAP, Ethernet, IPCP, LCP, LLC,
	      Loopback, PPP, PPPoE, Raw, Slip.

       -m     Minimal mode output. When operating in this mode, ipgrab displays only brief header information.

       -n     Don't display network-layer headers. The following protocols are considered to be network layer: AH, ESP, GRE, ICMP,  ICMPv6,  IGMP,
	      IP, IPv6, IPX, IPXRIP.

       -P string
	      Initiate a dynamic port mapping. This option must be followed by a string of the form `<protocol>=<port>', such as `http=8080'.

       -p     Dump  packet payloads beyond what IPgrab parses. In other words, if IPgrab does not parse a particular application, this option will
	      dump application data in hex and text format.

       -r FILE
	      Read packets from a file, rather than an interface. The file shoule be created in "raw" format, such as with '-w' option.

       -T     Do not display timestamps in minimal mode.

       -t     Don't display transport layer headers. The following protocols are considered to be transport layer: SPX, TCP, UDP.

       -v, --version
	      Display version number and then quit.

       -w FILE
	      Write the raw packets to a file, rather than the screen. The packets will not be parsed. The file can be read with the '-r' option.

       -x     Hex dump mode. After processing each layer, dump out the contents of that layer in hex and text. Only valid in main mode.

       expr   Berkeley packet filter expression.  See tcpdump(8) man page for details and examples.

NOTES

       Requires libpcap version 0.3 or greater to be installed.
