I get a daily Logwatch emailed to me with the similar error message in
the ModProbe section about ppp-compress-21. The number times varies
from day to day, usually a low number; in the report shown below it
shows "4." This machine's purpose to run caching proxy Squid for a
few Win98 users, all which can surf, get email, and use Usenet just
fine. My question is what does "Can't locate these modules:
ppp-compress-21" mean, and is there anything I need to do or fix?
This machine is text commands and runs ppp0 and Jay's firewall, and
dials an external modem. Here's the email report...
