 A couple of users have recently [http://tahoe-lafs.org/pipermail/tahoe-
 dev/2011-September/006676.html reported] errors from [http://tahoe-
 lafs.org/trac/tahoe-
 lafs/browser/trunk/src/allmydata/util/iputil.py?annotate=blame&rev=4971#L177
 iputil] when it couldn't find their {{{ifconfig}}} executable, e.g.:

 {{{

 We should catch this exception and report a useful error message, saying
 what the {{{sys.platform}}} was and asking them to report about their
 {{{ifconfig}}}, like David-Sarah [http://tahoe-lafs.org/pipermail/tahoe-
 dev/2011-September/006677.html did] on the list:
 {{{
 which ifconfig
 ifconfig --help
 ifconfig
 }}}

Comment (by zooko):

 Hi mk.fg! I was just investigating related bugs and I discovered this
 comment you added to this ticket. I'm sorry I didn't see it when you first
 posted it! I need to get more reliable monitoring of updates to
 trac+github...
