Mac/SnowLeopard and Wireshark

Wireshark has to be tweaked a bit due to permission issues on the Berekley Packet Filters. This has the info.

Since these settings are lost on reboot, a start up item can be created as shown here.

Also, if a module not found dialog box appears, follow these steps (taken from the long thread here):

You need to set the path to the folder that Wireshark looks in for MIBs &c, because the default in version 1.0.6 for Mac OS X is incorrect. In Wireshark, do the following:

• From the Edit menu, select Preferences...
• In the left pane of the Wireshark: Preferences window, click on Name Resolution
• For SMI (MIB and PIB) paths, click the Edit button
• In the SMI Paths window, click the New button
• In the SMI Paths: New window, in the name text box, type /usr/share/snmp/mibs/ and click OK
• Click OK
• Click OK
• From the File menu, select Quit

I found that it was also necessary to quit and restart X11 for the changed Wireshark preferences to take effect:

• From the X11 menu, select Quit X11

This gets rid of the loading the MIBS errors for me. YMMV. By the way, Wireshark is supposed to still be useable, even if you can’t get rid of these errors.
