Bitcoind
測試網中的 bitcoind 未同步
我將 bitcoind 安裝到 Linux 中。我在 testnet 模式下執行它，但它沒有同步，因為它沒有下載塊。
我在 bitcoin.conf 中有以下內容：
rpcport=8332 # Needed for testnet as default port for testnet is 18332以下是它顯示的內容
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" : "" }我有以下

我再次嘗試在 testnet 模式下執行 bitcoind，這次它正在下載塊。我不確定為什麼。也許這與我將 IP 地址放回 /etc/resolv.conf 中有關，我之前已將其註釋掉。
您找不到節點的原因是通過傳統引導方法可能沒有很多可用的節點（許多客戶端安裝時關閉了 UPnP，或者在防火牆後面並且無法接受傳入連接，並且具有入站連接的現有節點有時可能會分散）。如果你有足夠的耐心，你最終會得到一個連接。
如果您不想耐心等待，可以使用一種解決方法。您需要找到連接到測試網上節點的 bitcoind 的主機名（IP 地址或 URL）。一旦你找到了，關閉 bitcoind，然後編輯你的比特幣配置文件 (nano .bitcoin/bitcoin.conf) ：
addnode=<hostname>當您啟動 bitcoind 時，它將查看 conf 文件並嘗試以這種方式定義的每個節點。
您也可以簡單地關閉 bitcoind 並使用以下命令開始：
bitcoind -dameon -addnode=<hostname>成功連接的對等節點保存在 peers.dat 文件中，因此如果您嘗試連接的節點處於聯機狀態，這兩種方法同樣適用。有關 peers.dat 的更多資訊以及如何查看它可以在這裡找到（如果您想幫助朋友找到與 testnet 的連接）：如何閱讀 peers.dat 文件以獲取所有看到的對等點的列表或bitcoind已經連接到？
