Free ping utility software for linux

Ptunnel is an application that allows you to reliably tunnel TCP connections to a remote host using ICMP echo request and reply packets, commonly known as ping requests and replies. At first glance, this might seem like a rather useless thing to do, but it can actually come in your help in some cases.
Setting: Youre on the go, and stumble across an open wireless network. The network gives you an IP address, but wont let you send TCP or UDP packets out to the rest of the internet, for instance to check your mail. What to do? By chance, you discover that the network will allow you to ping any computer on the rest of the internet. With ptunnel, you can utilize this feature to check your mail, or do other things that require TCP.
Main features:
- Tunnel TCP using ICMP echo request and reply packets
- Connections are reliable (lost packets are resent as necessary)
- Handles multiple connections
- Acceptable bandwidth (150 kb/s downstream and about 50 kb/s upstream are the currently measured maximas for one tunnel, but with tweaking this can be improved further)
- Authentication, to prevent just anyone from using your proxy

Ingres::Utility::Netutil is an API to netutil Ingres RDBMS utility.

SYNOPSIS

use Ingres::Utility::Netutil;

# create a connection to NETUTIL utility

$netu = Ingres::Utility::Netutil->new();

# Attention: many arguments accept wildcard *

# showLogin($type,$vnode) - prepare to provide info on login VNodes
# and return netutil ouput
print $netu->showLogin(global,*);

#
# getLogin() - return one-by-one all login VNodes previously prepared
while ( ($type, $login, $vnode, $acct) = $netu->getLogin() ) {
print "Type: $typetName: $vnodetAccount: $acctn";
}

# showConn($type, $conn, $vnode, $addr, $proto, $listen)
# - prepare to provide info on connections of a VNode
# and return netutil ouput
print $netu->showConn(global,sample_vnode_name, *, *, *);

#
# getConn() - return one-by-one all connections of a VNodes previously prepared
while ( @conn = $netu->getConn() ) {
($type, $conn, $vnode, $addr, $proto, $listen) = @conn;
print "Type: $typetName: $vnodetAddress: $addrtProtocol: $proto";
print "tListen Address: $listenAddrn";
}

# createLogin($type,$vnode,$acct, $passwd) - create a new VNode
$netu->createLogin(global, new_vnode_name, sample_login_account, secret_passwd);

# createConn($type,$vnode,$addr,$proto,$listenAddr) - create a connection for a VNode
$netu->createConn(global, new_vnode_name, 192.168.0.1, tcp_ip, II);

# destroyConn($type,$vnode,$acct, $passwd) - destroy a connection from a VNode
$netu->destroyConn(global, new_vnode_name, 192.168.0.1, tcp_ip, II);

# destroyLogin($type,$vnode) - destroy a VNode and all connections
$netu->destroyLogin(global, new_vnode_name);

# quiesceServer($serverId) - stop IIGCC server after all connections close (die gracefully)
# if no $serverId is given, then all IIGCC servers are affected (carefull).
$netu->quiesceServer(sample_server_id);

# stopServer($serverId) - stop IIGCC server imediately (break connections)
# if no $serverId is given, then all IIGCC servers are affected (carefull).
$netu->stopServer(sample_server_id);

The server id can be obtained through Ingres::Utility::IINamu module.

This module provides an API to netutil utility for Ingres RDBMS, which provides local control of IIGCC servers for Ingres Net inbound and outbound remote connections, and also manage logins and connections to remote servers, a.k.a. VNodes.

Notes:

Ordinary user can create/destroy on his own private logins and connections.

SECURITY privilege should be granted to have access to other users private entries.

GCA privilege NET_ADMIN (generally a system administrator) needed to manage global type login and connection entries.

GCA privilege SERVER_CONTROL (generally a system administrator) needed to stop a communications server.

pingx is utility that uses the XNoOp(3x) call to see how fast your connection to your X server. Wonder whether your X performance is slower in a SSH tunnel? pingx can give you hard numbers so you can find out. It has an option to print out some details about the X server as well. Its also useful to see if a X server is up so you can fire up x2x or similar applications intelligently.
pingx is really nice for seeing if a remote display is up (use the options "-q -c 1"). It even returns immediately instead of waiting a second like the ICMP ping utility does, in case youre the impatient type.
Why would you need to know if a remote display is up? Well, I need to know because I have three monitors and two of them are on a dual-head machine. Im not sure whether the dual-head machine is running xinerama http://sourceforge.net/projects/xinerama/) or not this week, so Im unsure whether my center monitor is :0.1 or :0.0. This is important because I use x2vnc to control a third monitor over to the left, and if I give a bad DISPLAY variable to x2vnc it doesnt work.
Clueful people will probably point out that I should make :0.0 my left monitor and put a "Screen 1 RightOf Screen0" statement in my XF86Config-4, but I thought that writing an X protocol-level ping utility might be a fun thing to do instead.
It compiles under FreeBSD 4.3-RELEASE and Linux ok. I got lazy and make different LDLIBS lines in the Makefile. Ill use autoconf/automake in the future, but just edit the Makefile for now.
Enhancements:
- initial release. Has count, verbose, and quiet flags. Needs to have statistics and a signal handler written. Needs to be autoconfed and automaked.

Sethi Search Utility provides a simple command line utility to submit a search to Google, Yahoo!, or MSN.
Sethi Search Utility is a simple command line utility to submit a search to Google, Yahoo!, or MSN and show the (text) results on standard output. Support for several search engines is included.
Its currently in serious need of a re-write, especially to avoid scraping and become a good engine using the search APIs provided.
Enhancements:
- The Google configuration was updated.

Arping is an ARP level ping utility. Its good for finding out if an IP is taken before you have routing to that subnet. You can also ping MAC addresses directly.

Broadcasts a who-has ARP packet on the network and prints answers. VERY useful when you are trying to pick an unused IP for a net that you dont yet have routing to. Then again, if you have no idea what Im talking about then you prolly dont need it.

Arping is util to find out it a specific IP address on the LAN is taken and what MAC address owns it. Sure, you *could* just use ping to find out if its taken and even if the computer blocks ping (and everything else) you still get an entry in your ARP cache. But what if you arent on a routable net? Or the host blocks ping (all ICMP even)? Then youre screwed. Or you use arping.

pingmon is a small PING monitor, it just pings a server 5 times and displays the results.

Dont really know how usefull it will be to anyone, but here it is!

Change the .theme file to change the labels and the servers... ill try to do some sort of "click to change" thing later.

Email Administration Utility provides an IMAP-based email account management utility.
The Email Administration Utilities package can be used to manage email accounts with a series of PHP-based scripts through a browser.
Addition, Removal, and modification of accounts is possible as long as an IMAP port is available on the mail server.
The Mailadmin project was originally designed to help owners of domains that were hosted by Hub.Org Networking Services. The company wanted users to be able to create, remove or modify email accounts when ever they wanted, giving them a quicker turnaround for Mail Administration Purposes.
As the utility was developed, tested and matured into what it is today, many users requested more features or contributed reports of issues to help improve the utilities stability. Hub.Org has given me permission to release the utility as an Open Source package so that others may also benifit from the simplicity that the Mailadmin utility offers to those who need complete control over email accounts.
With this in mind, I intend to continue development by adding new features as they are requested and fix any issues that may pop up. The more users who use and test the features that the Mailadmin utility offers will help to improve the functionality offered by Mailadmin. I have opened a Sourceforge account to help manage the development and releases of the utility as it matures into what users and developers see the Mailadmin to be.
Main features:
- Administrator:
- Adding/Deleting Email accounts.
- Setting Account Quotas.
- Obtaining Administrative Access Over Older Accounts.
- Changing An Accounts Password.
- Interfaces with the Cyrus IMAP/POP3 server.
- Transaction Log system, allowing you to track changes or to help debug issues.
- Standard User:
- Changing The Accounts Password.
- In Development:
- Transaction Log system, allowing you to track changes or to help debug issues.
