Network String Development Release 0.15

Due to certain commercial products a network utility program had to be renamed. Since that was going on it was renumerated and labeled development release so it could get pushed out. netstr-0.15 is a collection of small network tools put together to compliment the network toolkit. The tools are modules that are called at run time and managed by the netstr main program. The modules are:

  • scan: simple small ipv4 portscanner
  • scan6: by port ipv6 scanner
  • passive: passive ipv4 port watcher & recorder
  • tcpdump: mini tcpdumper
  • arpsniffer: watches for arp traffic

Invoking netstr is similar to the dnet utility:

$ ./netstr                                                                        
Usage: netstr <command> <args> ...
netstr scan --ping --conn --dgram --port n-N --time s.ms \
            --extra -V {target}
netstr scan6 --dgram --port N {ipv6addr}
netstr passive --if dev --threshold n --polls count \
               --extra --no-verify {pcap-expr}
netstr tcpdump --if dev --polls count --decode {pcap-expr}
netstr arpsniff --if dev --polls count --decode {pcap-expr}

Please note that netstr is experimental and was just recently actively developed again. Your mileage may vary ... a lot.

MySQL Status Page Check using Nagios Part 1

Nagios can check anything anyone is willing to write it to check. In other words if there is a way to reap results then Nagios can act on those results whether they be a set of strings, numbers or some combination therein. This two part series goes over setting up a very rudimentry MySQL status page check using common tools found on a BSD-Unix, Unix or Linux system (and it not, generally easy enough to install). This first part goes over requisites, assumptions and the status pages themselves. The second part is the Nagios end of things and of course the "other cool stuff" the creative mind can do with it all.

pwutils-0.6 Available

The single line print format for pwutils never worked right. Well now it does. The pwutils collection are some very small programs written in C, Perl, Python and Bash that do, among other things:

  • Userinfo print similar to BSD systems
  • Group report
  • Various user reports
  • A kinda sorta like the pw utility pwutil front end.

Should build and run on almost any Unix/Linux/BSD system.

Leetness of Simplicity

I was thinking about doing another article about X windows when I realized not much has changed on the surface. So instead, to tide us over until I finish the current article I snagged a few old school simple window manager pictures from Xwinman.

Using Payloads to Probe UDP Ports

With no lubricant! A few years ago I was involved in an effort to move the payloads that were embedded in the Nmap code (and hence, compiled into the executable) to a file. I learned a lot, especially that I am a lousy C++ coder (my work basically had to be rewritten from scratch... but it was still fun!). I did learn one thing though, Maps in C++ are really friggin cool and if I were a C++ programmer I would probably use them every chance I could. They kinda sorta remind me of anon hashes in Perl ... but not exactly the same. Regardless, here is a short text on why we did it and an overview of how it works:

Vignette Effects using The GiMP

Ever wanted to process your own photos so they look older (for some strange reason)? A quick down and dirty how to add some vignette and edge shading effects to images using the GNU Image Manipulation tool or GiMP. Enjoy, have fun and if you find mistakes... I might fix them!
