Very interesting. The '/i' modifier means "ignore case". [a-z,A-Z] shouldn't
be necessary, because we're ignoring case. That sounds like a Perl/Redhat bug
to me. I do use the '/i' modifier in other places which don't seem to have the
problem, although those patterns are much simpler. I could re-write the
patterns to use Perl's Unicode composite properties, like
if ($var =~
/^((\p{IsAlpha}[\p{IsAlnum}\-]*\.)*(\p{IsAlpha}[\p{IsAlnum}\-]*)))
But then I'd have to add "use utf8" and that could restrict the portability of
the module
MRTG itself checks to see if the environment variable "LANG" is set to UTF-8
and refuses to run if it is. Maybe that should be extended to cfgmaker until
Perl gets fixed.

Subject: [mrtg] Re: cfgmaker - Cisco switches
A colleague of mine has indicated that this is an issue with MRTG's
SNMP_util.pm; a regular expression line is apparently not handled properly, and
a replacement resolved the situation:
# if ($var =~ /^(([a-z][a-z\d\-]*\.)*([a-z][a-z\d\-]*))/i)
if ($var =~ /^(([a-z,A-Z][a-z,A-Z\d\-]*\.)*([a-z,A-Z][a-z,A-Z\d\-]*))/i)
Now if this is Perl's, MRTG's, or Redhat's fault (I include Redhat
since I'm using RH9 and I've run into several interesting problems with it), I
don't know ... but the above line replacement has provided the desired effect.
