Wireshark · Wireshark-users: Re: [Wireshark-users] adding MIB files (Andrew Hood)

[Stuart Kendrick <skendric@xxxxxxxxx>]

hi andrew,

ok, got it.

i was assuming that specifying the directories was sufficient ... now i'm 
specifying each MIB file independently, and Wireshark is finding them (in the 
list of directories i've provided)

and the console window is appearing, telling me about the MIB files i'm missing 
... but i know how to solve that

i can see that i will be building smi_modules and smi_paths programmatically ... 
rather than typing all this in.  but that's OK.  [i don't mind waiting longer 
for Wireshark to load ... in exchange for the decodes i get when the relevant 
MIB file is compiled!]

i'm in business, thank you for the assistance,
