Hi Steven,

as I can see from your mail header, that your system clock is 6 hours in the past.
This will give you certain network problems - like you've encountered.

1. Choose the correct timezone by placing an appropriate copy of the zoneinfo file
   (in you case /usr/share/zoneinfo/America/Chicago) as /etc/localtime.
   There come suitable graphical tools to accomplish this with the distros.

2. Adjust your system clock to reflect the correct time:
   a) use date(1)
     or even better:
   b) use a network time server:
      -) via e.g. ntpdate and place a call of it into your ppp-up script
        or if you have a permanent internet connexion
      -) you can run a NTP server (ntpd).
         There are lists of NTP servers (use of stratum 2 is recommended) available at e.g.:
   Don't forget to update your hardware clock with hwclock(8) after you've
   corrected your system clock.

3. If you run only a U*X OS, change your system clock to UTC and add a "-u" option
   to the hwclock(8) call at boot-time.

HTH, kind regards,
