Free icmp echo software for linux

Command Line WRAPper is a tool that provides an easy way to build and run commands from input lines, avoiding the use of shell script. It is similar to xargs.

clwrap can make great things with the locate command, and is low resource intensive. It can also do some not-quite-fun works like multiple configure/make/make install after a fresh system installation. In practice, you have to generate a list of files/directories you want to manage, clwrap takes it in standard input and apply the command you want to apply for each files (lines) in input.

But you can do much more, in fact, its up to you to find how to use it ;).

examples:

- copying several files into one specific directory:

locate myfiles | clwrap -e cp {} mydir/

- renaming several files:

ls -1 ultra*
| clwrap -e "echo -n mv -v {}" -e "echo {} | sed s/ultra/ /"
| clwrap -e {}

- running a specific line in the shell history:

history | grep "482" | head -n 1 | sed s/ *[0-9]* *// | clwrap -v -e {}


- try all tv norms and frequency tables possible combinations with scantv:

cat norm
| clwrap -e "cat freq | clwrap -e echo scantv -n {} -f {}"
| clwrap -e {} > file 2>&1

- reformat source code, after a backup of course:

ls -1 | clwrap -e "cp {} {}.orig && flip -u {} && cat {}
| sed s/^[ t]*$//;/^$/d
| indent -kr -bad -bap -bbb -sob -i8 -l100 {} -o {}.tmp
&& mv {} tmp && mv {}.tmp {}"

Echo is a framework for developing object-oriented, event-driven Web applications.
Echo removes the developer from having to think in terms of "page-based" applications and enables him/her to develop applications using the conventional object-oriented and event-driven paradigm for user interface development.
Knowledge of HTML, HTTP, and JavaScript is not required. Echo is open-source software distributed under the terms of the Mozilla Public License or the GNU LGPL License.
Enhancements:
- Version 1.1.4 adds support for specifying the order of tab-based navigation of components. The release also fixes bugs reported in previous versions, including the issues discovered with setting component focus.

- vibrato

Aps is a small tool for analyzing network traffic. It prints out a great deal of information about the relevant protocols including TCP, UDP, ARP, and ICMP.
It allows you to filter IP addresses, hardware addresses, ports, and specific protocols. It comes with a little GTK-GUI displaying packet counters for each protocol.
APS tries to print detailed info about network frames that are received from the SOCK_RAW (ETH_P_ALL) socket. I am not sure if this is the clean way, but it works fine. APS prints info about the hardware layer and the IP and TCP/UDP/ICMP header.
The tail of the packet (mostly the data) wich could not be interpreted is written on the screen as ascii/hex-dump or both (your choice).

Enhancements:
- added break for Packet-counter and fixed some minor bugs

libshape is library for limiting the download rate of programs.

libshape library works entirely in user space with existing programs through LD_PRELOAD.

Are tested with threaded programs. This limiting is done entirely in user space. You only need to start Your program with

$ LIBSHAPE_CFG=/home/user/.libshape/program1
LD_PRELOAD=libshape.so
./program1

to limit download rate to 14Kbps You need to convert this rate to Bps:

$ echo $[14 * 1024 / 8] > /home/user/.libshape/program1

You cant dissable limiter, but you can set it to very high limit.

You can change download rate on the fly. Changes will occur in 1-5 seconds, becous there are some buffers in kernel space.

tcptraceroute project is a traceroute implementation using TCP packets.

The more traditional traceroute(8) sends out either UDP or ICMP ECHO packets with a TTL of one, and increments the TTL until the destination has been reached. By printing the gateways that generate ICMP time exceeded messages along the way, it is able to determine the path packets are taking to reach the destination.

The problem is that with the widespread use of firewalls on the modern Internet, many of the packets that traceroute(8) sends out end up being filtered, making it impossible to completely trace the path to the destination.

However, in many cases, these firewalls will permit inbound TCP packets to specific ports that hosts sitting behind the firewall are listening for connections on. By sending out TCP SYN packets instead of UDP or ICMP ECHO packets, tcptraceroute is able to bypass the most common firewall filters.

libpal allows you to create your own forged IP, TCP, and ICMP packets. libpal project is straightforward to use and is a powerful tool for building artificial TCP/IP packets.
