Free bsnmp ping software for linux

bsnmp is a miniSNMP daemon. For a couple of projects that involved controlling software on a couple of machines from a single controlling machine I decided to use SNMP. After looking at several available SNMP implementations I started to implement my own SNMP stuff, because what was available was not really what I needed (for several reasons). The result of this work is bsnmp.

bsnmp consists of the following pieces:
a library libbsnmp that includes ASN.1 handling, the SNMP protocol version V1 and V2C and a number of helper stuff to simplify writing of SNMP agents and clients.
the gensnmptree tool that generates the C- and H-files from an object hierarchy description (.def file).
the gensnmpdef tool that generates an initial .def file from a MIB. This requires the libsmi library.
bsnmpd - the SNMP daemon.
snmp_mibII - an implementation of the standard MIB-II sub-tree.
snmp_ntp - a partial implementation of the experimental NTP MIB.

The bsnmpd daemon implements just the bare minimum that is needed for such a daemon: the system group, parts of the SNMP group and a private tree that does the following:

handling of loadable modules. This allows loading/unloading parts of the tree at runtime or configuration time.
handling of communities. A table that allows loaded modules to create new communities at run-time (ILMI is a consumer of this). This table can be disabled for obvious reasons.
handling trap destinations for V1.
several configuration parameters like the protocol versions to handle, buffer sizes and so on.
tables that manage the UDP and local unix ports the daemon is listening on.
statistics and debugging
All real functionality is implemented via loadable modules and hence the daemon can be used for remote-control functions that have nothing to do with network management.

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.

KDE Ping is a network/IP ping utility for KDE.

MultiPing provides a multi-protocol, multi-host, graphical ping utility.

MultiPing is a multi-protocol, multi-host, graphical ping utility, used to ensure a set of hosts are up and running and providing the expected services.

Currently, the supported protocols are ICMP Echo, HTTP, SMTP, and POP. This goes beyond simply using ICMP Echo to determine the status of a server to actually testing the protocols the server is expected to be providing.

MultiPing is provided as a runnable .jar file. You should be able to simply double-click the multiping.jar file to launch MultiPing. You can then right-click in the main window to access the context menu which will allow you to add, edit, and delete hosts from the list.

Each host can have one or more of the supported protocols enabled. For each enabled protocol zero or more arguments can be provided which are used to status the specified protocol.

A file will be created in the same directory as multiping.jar named multiping.dat. This stores the list of hosts, along with the protocols enabled for each host and the arguments to each enabled protocol.

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.
