Tools for Network Diagnostic

It might be useful to you, to access network diagnostic tools over the Internet, to check the situation from somewhere over the network. This is, why I provide this tracer for you. Keep in mind, this is no hacker tools to access hidden information. They are just tools admins use in every day work to trouble shoot network related problems.

There are other pages like this, check out the List of Gabor Szabor on tracert.com and the web site traceroute.org from Thomas Kernen. In addition to that, there is the Pinger Project.
Usage of this service is currently unrestricted, but I will restrict this to registered users in the near future. If you are not yet an registered user of eckes.org I recommend you LogIn or create a new user account. It is free.

Instructions

Destination

You can enter the destination of a trace. It could either be a hostname (e.g. destination: host.inka.de) or you can specify an email address (e.g. destination: This e-mail address is being protected from spambots. You need JavaScript enabled to view it ) or a user ( This e-mail address is being protected from spambots. You need JavaScript enabled to view it ).

The following list shows for which modes you can supply a host or useraddress.

Mode

Ping
From www.inka.de datagrams are sent to the specified destination-host (hostname or IP-Address) and the roundtrip-times are displayed.

 

Traceroute -n
The path from www.inka.de to the specified destination-host will be listed on the screen. All intermediate hosts are printed with addresses only. This is faster and doesn't generate such a big netload. Failures in examining the route will generate small asterisks.

 

Traceroute
This is the same as above but prints all the hostnames. This is a little bit slower and generates a lot of DNS load.

 

Traceroute PRIDE
Using the PRIDE Tools do detect not only the Traceroute informations, but in Addition to that the AS routing path.
Unfortunatelly prtraceroute does not work very stable, yet. Thanks to S+P for the whois server service.

 

Mail Verify
The SMTP Function 'VRFY' is used to check the reachability of a specified E-Mail address. If you only specify a hostname the general reachability of the remote mailsystem is checked. Some hosts might not recognize faulty addresses.

 

Mail Expand
If possible 'EXPN' is used to receive information about the real recipients of a given E-Mail address. This is not supported or allowed on all mailsystems. If you supply only a hostname only the generally reachability is checked.

 

Finger -l
Prints detailed Information about the specified user or informaton about a single host.

 

Finger -s
Table with informations about user or host.

 

Webping
Outputs the result of a "GET / HTTP/1.0" Operation, send to the destination host. You can see the Server's aswer like Software Version and some details about the homepage. Especially usefull to test if the Web Server is reachable from the Internet.
