Hello internetwork

Since years I was using tools for easy tasks like ping, traceroute, domain lookup using shell and I realized, that this is not as flexible as I wish. It may be cumbersome to just get that shell access if I’m under way and does not have my homebox (eg. my notebook) with me, or it’s just difficult to overcome the local security rules to gain access to one of my hop-servers.

To overcome the access limitations, I started developing my own “frequently used tools” (FUT) web page, which has really some advantages compared to millions of such tools on the internet:

  • I do not have to search such tools
  • It is always online (runs on my own server)
  • It is my swiss army knife, where I have all I need and just what I need
  • Bugfixes, personalization can be done instantly
  • It is platform independent
  • It is secure

The tools are located at http://resolv.hu/toolbox
It supports two languages: English and Hungarian

The page includes:

Cisco password decoder

Yes, the good old Type 7 passwords. My favourite situation is when I have to use online tools which I don’t know, don’t own, and simply can not be sure if they are logging my input or not. Not with my tool, I am sure what is running on my server. 🙂

DNS resolver

Simply skip those skinny nslookups, this tool uses dig, the look and feel which I like.

E-mail MIME header decoder

How often do you need to view MIME encoded E-mail message subjects? Well, I do very often.

BGP ASDOT and ASPLAIN converter

This is not as frequent to use as I had thought before, but sometimes it is just necessary to double check if I correctly represented an AS or not.

The tool grows, new features are coming, feel free to use it, please also freely send me suggestions, ideas and I will (try to) implement them.
