+ * <p>
+ * A <code>ProxyNode</code> represents a Tor process that is configured as

+ * </p>
+ *
+ * <p>
+ * <b>Pay extra attention when using in private network!</b> Using proxy nodes
+ * in private networks in the same way as router nodes will fail! Tor has two
+ * different strategies for downloading network status documents: Directory
+ * caches (router nodes) download these documents after every HUP signal and
+ * then accept all contained router entries. But directory clients (proxy nodes)
+ * only download network status documents, if the most recent download lies at
+ * least 30 minutes in the past, and then accept only those of the contained
+ * router entries that are at least 10 minutes old. However, when starting all
+ * nodes of a private network at once, directories cannot contain 10 minutes old
+ * router descriptors. You have at least the following options to cope with this
+ * problem:
+ * </p>
+ *
+ * <ul>
+ * <li>Use router nodes instead of proxy nodes,</li>
+ * <li>start proxy nodes with a delay of at least 10 minutes to be sure that
+ * the router descriptors stored at directory authorities will be accepted by
+ * directory clients, or</li>
+ * <li>change the constants <code>ESTIMATED_PROPAGATION_TIME</code> and
+ * <code>NETWORKSTATUS_CLIENT_DL_INTERVAL</code> in Tor to values smaller than
+ * your overall HUP time for starting the network.</li>
