virtualenv中的pip获取ConnectTimeoutError

Question

我目前正在尝试在python-3.4virtualenv中安装包，并且不断收到这些重试/TimeoutErrors。

(backend)root@XXXX:/var/virtualenvs# pip3 install -r backend-freeze.txt
Collecting cassandra-driver==2.7.2 (from -r backend-freeze.txt (line 1))
  Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after connection broken by 'ConnectTimeoutError(<pip._vendor.requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x7f4d7faf94a8>, 'Connection to pypi.python.org timed out. (connect timeout=15)')': /simple/cassandra-driver/
  Retrying (Retry(total=3, connect=None, read=None, redirect=None)) after connection broken by 'ConnectTimeoutError(<pip._vendor.requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x7f4d7faf9588>, 'Connection to pypi.python.org timed out. (connect timeout=15)')': /simple/cassandra-driver/

不知道这是怎么回事。我没有使用代理(这似乎是其他有类似/相同错误经验的人的情况)。

所以，我发现了这个问题。我不确定这是怎么发生的，但是有人在输入链中放了一行DROP all anywhere/anywhere iptables行。

我保证不是我干的，但是删除这行代码肯定解决了问题。现在来找出哪个员工认为这是个好主意。
