Re: Make The Netopia R9100 Router To Crash

[Rob Tashjian <rwt () NETOPIA COM>]

Well, had you bothered to contact Netopia first, (what!, you didn't!
shame on you!), you would have found that the problem has been
resolved for some time now.  The version of firmware against which
you are reporting this problem (4.6) is close to a year old.  The
current version of firmware is 4.8.2, or two feature releases and a
number of bug fixes removed.  Please upgrade to 4.8.2.

In the future, you should report security problems to
    security () netopia com
or call Netopia Tech Support and have the problem logged so that
it can either be fixed, or as in this case, you can be directed to
upgrade your firmware.

ps.  Whose router do you have passwords to anyhow:^?  And why
are you trying to delete the logs:^?
