I'm using varnish on a single box (192.168.56.102) and apache on other box (192.168.56.105). on varnish box - in /etc/varnish/default.vcl

backend default {
.host = "192.168.56.105";
.port = "80";
}

and /etc/default/varnish

DAEMON_OPTS="-a :80 \
         -T localhost:6082 \
         -f /etc/varnish/default.vcl \
         -S /etc/varnish/secret \
         -s file,/var/lib/varnish/$INSTANCE/varnish_storage.bin,3G"

Question 1. Varnish not Caching (MISS)

When i access 192.168.56.102 it MISS cache and goes to apache box.

curl -I http://192.168.56.102  [vernish box]

HTTP/1.1 401 Authorization Required

WWW-Authenticate: Basic realm="iExplore Development"

X-Varnish: 587747945

Via: 1.1 varnish
Connection: keep-alive
X-Cache: MISS

Question 2. Varnish control terminal isn't reacting on apache (using drupal-pressflow-6) box - varnish admin (/admin/configurations/varnish)

  VARNISH CONTROL TERMINAL: 192.168.56.102:6082

  entered VARNISH CONTROL KEY:

  Save configuration

  STATUS: The Varnish control terminal is not responding at 192.168.56.102 on port 6082.

Thanks ahead of time
