Legend for OpenSSL’s dhparam output

I was curious to find out the meaning of all the dots, pluses and stars that openssl dhparam outputs while computing Diffie-Hellman parameters.

To make a long story short, here’s the legend:

  • . : A potential prime number was generated.
  • + : Number is being tested for primality.
  • * : A prime number was found.

MIBS Missing Error on Wireshark Startup

I've installed Wireshark 1.0.5 without SNMP MIBs on Windows. Upon startup I received an error dialog about missing MIBs, containing text like:

The following errors were found while loading the MIBS:
-:0 1 module-not-found failed to locate MIB module `IP-MIB'
-:0 1 module-not-found failed to locate MIB module `IF-MIB'
-:0 1 module-not-found failed to locate MIB module `TCP-MIB'
(snippet from http://www.wireshark.org/lists/wireshark-dev/200711/msg00249.html)

The solution: rename or delete the file smi_modules under the Wireshark directory.
