Question

我正在尝试从家里访问VPN时访问我们的TFS服务器，但它只给了我以下消息：

Connecting to TFS...
git-tf: Permission denied: connect

我正在使用完全限定的URL，其他所有内容都可以在VPN上正常运行。我可以尝试任何身份验证配置设置吗？我无法在任何地方找到任何在线提及。

当然，当我在办公室时，它运作得很好。

这与Java bug 703177有关。 Java 7带来了IPv6支持，据报道，思科的VPN客户端拒绝IPv6流量。您可以强制Java使用IPv4作为其java.net.preferIPv4Stack系统属性的传输。

您需要编辑启动JVM的git-tf启动程序脚本才能执行此操作。您可以在-Djava.net.preferIPv4Stack=true和git-tf中将git-tf.cmd参数添加到启动行。

git-tf的最后一行应该是：

exec java -Xmx512m -classpath "$GITTF_CLASSPATH" \
    "-Dcom.microsoft.tfs.jni.native.base-directory=$BASE_DIRECTORY/native" \
    -Djava.net.preferIPv4Stack=true \
    com.microsoft.gittf.client.clc.Main "$@"

git-tf.cmd的第47行应该是：

java -ea -Xmx512M -cp %GITTF_CLASSPATH% "-Dcom.microsoft.tfs.jni.native.base-directory=%BASE_DIRECTORY%native" -Djava.net.preferIPv4Stack=true com.microsoft.gittf.client.clc.Main %*

Git-tf thowing权限被拒绝通过VPN
