Free to ping software for linux

Web Ping is a program for testing your internet connection.

Web Ping is a simple application to test an internet connection to a perticular site. I created this application after my work moved locations and half our network stayed in the old building and the other half moved with us to the new location.

A flaky (significant point) VPN was set up to keep the two connected. Since a couple of the unmoved servers were of interest to me, I keeped checking to see if they were still accessable with the ping command before doing any serious work with them.

A quick and pathetic Google resulted in no other program that meet my needes, so I wrote one.

Insted of doing an actual network ping, Web Ping tests a connection by downloading a web page on a given server. The size of the page and time are stored in memory and the times are graphed. In this way, sites that block network a ping can still be tracked.

Web Ping also keeps track of the largest and smallest download times per session and also tracks the max and min values currently on the graph. Times of interest are graphed in a color which represents if it is a max or a min. (see figure one). The history tab also lists all the max values as they have been recevied.

A running average is also calculated with each download. The files downloaded are not processed or stored in any way. This prevents any security problems that can normaly happen in a web browser enviroment. The only two pecies of information retained about a downloaded file is the size and time.

Usage:

There are two ways to use Web Ping, GUI or CLI mode. The simplest of the two modes is CLI. Web Ping can be started in CLI mode by passing a url to the jar file in a command line interface like this: "java -jar WebPing.jar http://localhost". Web Ping will automaticly start getting statistics on the requested url, printing results to the screnn.

To quite, press q and then then ENTER key. CLI allows the user to Most people will probably want to use the GUI mode which has a history graph and allows the user to start and stop the session.

The best way to run Web Ping is in GUI mode. GUI mode allows the user start and stop the ping process at will and to change the site that is pinged. Users can also see more information about about the history of the pings and view max values and min values easily. There are three tabs on the top of the page, the first is the application, second is the history list, and the last give information about the application.

httping is a "ping"-like tool for HTTP requests. Give it a URL and it will show how long it takes to connect, send a request, and retrieve the reply (only the headers).
httping can be used for monitoring or statistical purposes (measuring latency).
Enhancements:
- A big memory leak in the SSL code was fixed.
- An audible ping mode was added.

BSNMP ping is a module for bsnmpd which allows you to measure latency and reachability. It sends out ICMP packets to the configured hosts.

A history of received packets is maintained, and you can query via SNMP how many dropped packets, maximum/minumum latency and other stats for that history period.

As bsnmpd only runs on BSDs (seems that way), this will also be the case for bsnmp-ping.

EXAMPLES

The following example pings two hosts. The first gets pinged once per second, and keeps a history for 300 seconds. The second is pinged 5 times per second, and the history is kept for 30 seconds.

The following would be added to /etc/snmpd.config:

begemotSnmpdModulePath."ping" = "/usr/local/lib/snmp_ping.so"
%ping
pingHost.1 = "10.8.9.2"
pingInterval.1 = 100
pingHistory.1 = 300

pingHost.2 = "2.2.2.2"
pingInterval.1 = 20
pingHistory.1 = 150

BLOG-X-PING is a lightweight yet powerful library for PHP to automatically ping blog aggregator services to notify them of updated syndication feeds, using Weblogs.Com compatible XML-RPC pinging services.

The system allows you to automatically ping many servers every time you creates a new post or update old ones on your blog, the system can send an XML-RPC signal to several ping servers, which can then add your blog to their list of recently updated blogs, meaning that new content on your blog/site can be widely advertised automatically as soon as you add it.

The project has been made available as open source under the LGPL licence.

fping is a ping like program which uses the Internet Control Message Protocol (ICMP) echo request to determine if a host is up. fping is different from ping in that you can specify any number of hosts on the command line, or specify a file containing the lists of hosts to ping.

Instead of trying one host until it timeouts or replies, fping will send out a ping packet and move on to the next host in a round-robin fashion.

If a host replies, it is noted and removed from the list of hosts to check. If a host does not respond within a certain time limit and/or retry limit it will be considered unreachable.

Unlike ping, fping is meant to be used in scripts and its output is easy to parse.

Problem and Issues:

With a large a number of IP addresses in use, its becomes more and more time consuming to check on which IP addresses are actively in use, and which critical machines (routers, bridges, servers, etc) are reachable. One example is we have a program which goes through all of our routers arp caches looking for IP addresses that are in use. After finding a list of IP addresses that arent in any arp caches fping can then be used to see if these IP addresses really arent being used, or are just behind the routers. Checking 2500 hosts (99% of which are unreachable) via ping can take hours.

fping was written to solve the problem of pinging N number of hosts in an efficient manner. By sending out pings in a round-robin fashion and checking on responses as they come in at random, a large number of hosts can be checked at once.

Unlike ping, fping is meant to be used in scripts and its output is easy to parse.

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.

pmping provides a parallel multiple host ping with audible results (beep on the PC speaker).
pmping is a script that pings multiple hosts in parallel and gives audible results depending on host state.
The sounds come from the internal PC speaker, thus not needing a sound card. It beeps when a host OS is losing many packets, or when it is down.
If the host is down, the script can send an email notification or run a command. All aspects are fully customisable by the user.
Main features:
- Logs notifications to standard output.
- Reloads config file on-the-fly.
- Ability to run a command when a host is down.
- Sends e-mail notifications when a host is down and when it comes up.
Enhancements:
- Corrected dynamic config reload (wasnt really working).
- Try to catch SMTP connection errors when sending notification e-mails.
- Changed the way we check network errors (regex was not working).

PingNode will ping a list of network devices at a specified interval. PingNode will then create a record in a MySQL database for each ping indicating that the node was there or not there.

It will also send an email if the node is found to be down. The index.php page contains a list of monitored hosts with current status.

A detail page contains historical data for a given host.

ToDo:

Seperate table for hosts
Query data by date range
Dynamic host add/delete/modify
Custom Reports
disk space monitor
Process/Service monitor
