I installed bitcoind into Linux. I'm running it in testnet mode but it is not synchronizing as it is not downloading blocks.
I have the following in bitcoin.conf:
rpcport=8332 # Needed for testnet as default port for testnet is 18332
Below is what it shows from bitcoind getinfo
:
{
"version" : 80600,
"protocolversion" : 70001,
"walletversion" : 60000,
"balance" : 0.00000000,
"blocks" : 0,
"timeoffset" : 0,
"connections" : 0,
"proxy" : "",
"difficulty" : 1.00000000,
"testnet" : true,
"keypoololdest" : 1392428204,
"keypoolsize" : 101,
"paytxfee" : 0.00000000,
"errors" : ""
}
I have the following for ufw status verbose
for the firewall:

Can anyone suggest any solutions to get bitcoind to synchronize and download the blocks?
Update on 2014-03-13:
I tried removing bitcoin.conf and running this:
bitcoind -testnet -debugnet -printtoconsole
and I got the following:

Error: To use bitcoind, you must set a rpcpassword in the configuration file:
/home/jlp/.bitcoin/bitcoin.conf
It is recommended you use the following random password:
rpcuser=bitcoinrpc
rpcpassword=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
(you do not need to remember this password)
The username and password MUST NOT be the same.
If the file does not exist, create it with owner-readable-only file permissions.
It is also recommended to set alertnotify so you are notified of problems;
for example: alertnotify=echo %s | mail -s "Bitcoin Alert" [email protected]

Can anyone discern from above, what the problem is and how to solve it?
0 addresses found from DNS seeds
and theconnection timeout
you get when executingGetMyExternalIP()
implies network configuration issues. Trytraceroute checkip.dyndns.org
and see if your request goes through. Doesnslookup google.com
return a valid IP? If yes, set your firewall (and router, if the latter doesn't work) in DMZ mode and see if anything changes.traceroute checkip.dyndns.org
and I got 13 lines (hops?) back.nslookup google.com
returns 11 IP addresses for google.com. However, I tried running bitcoind in testnet mode again and this time it's downloading the blocks. I'm not sure why. Maybe it had something to do with me putting back an IP address into /etc/resolv.conf, which I had previously commented out.
