<p>I'm running bitcoind on a remote server (so I can only use the "headless" version). However, the client is not connecting to the bitcoin network. The "getinfo" command shows "connections: 0". I have also been keeping an eye on the blocks folder and there is no change there (when running bitcoin on the local machine, I can see files being created and updated there).</p>

<p>Here's what my bitcoin.conf looks like:</p>

<pre><code>daemon=1
server=1
rpcuser=&lt;redacted&gt;
rpcpassword=&lt;redacted&gt;
rpcport=&lt;redacted&gt;
rpctimeout=60
</code></pre>

<p>Port 8333 is open for UDP traffic in my firewall and I have used an external port scanner to verify that it is open. However, I understand that that's not actually necessary for outgoing connections. I've also checked that my date / time is synchronized (this was suggested in some of the threads that I found on this topic).</p>

<p>What are other possibilities?</p>

What output do you get from `netstat | grep 8333`?
