download some files from internet,but it always failed download, so I get into the container to do some test with wget, it shows that the container can connect to internet server but cannot download files. *vcap(a)193r3tpboqm:~/tmp$ ping www.baidu.com <http://www.baidu.com/>* *PING www.a.shifen.com <http://www.a.shifen.com/> (180.97.33.107) 56(84) bytes of data.* *64 bytes from 180.97.33.107 <http://180.97.33.107/>: icmp_seq=1 ttl=50 time=27.8 ms* *64 bytes from 180.97.33.107 <http://180.97.33.107/>: icmp_seq=2 ttl=50 time=27.7 ms* *^C* *--- www.a.shifen.com <http://www.a.shifen.com/> ping statistics ---* *2 packets transmitted, 2 received, 0% packet loss, time 1001ms* *rtt min/avg/max/mdev = 27.740/27.814/27.888/0.074 ms* *vcap(a)193r3tpboqm:~/tmp$ wget www.baidu.com <http://www.baidu.com/>* *--2015-11-06 15:25:49-- http://www.baidu.com/ <http://www.baidu.com/>* *Resolving www.baidu.com... 180.97.33.108, 180.97.33.107* *Connecting to www.baidu.com <http://www.baidu.com/>|180.97.33.108|:80... connected.* *HTTP request sent, awaiting response... 200 OK* *Length: unspecified [text/html]* *Saving to: `index.html'* * [ <=> ]0 --.-K/s * *vcap(a)193r3tpboqm:~/tmp$ ll | grep index.html * *-rw-r--r-- 1 vcap vcap 0 2015-11-06 15:25 index.html* *vcap(a)193r3tpboqm:~/tmp$ * but the host where dea running can wget files successfully *root(a)dea03:~# wget www.baidu.com <http://www.baidu.com/>* *--2015-11-06 23:30:28-- http://www.baidu.com/ <http://www.baidu.com/>* *Resolving www.baidu.com <http://www.baidu.com/> (www.baidu.com <http://www.baidu.com/>)... 180.97.33.107, 180.97.33.108* *Connecting to www.baidu.com <http://www.baidu.com/> (www.baidu.com <http://www.baidu.com/>)|180.97.33.107|:80... connected.* *HTTP request sent, awaiting response... 200 OK* *Length: unspecified [text/html]* *Saving to: `index.html.1'* * [ <=> ] 97,308 --.-K/s in 0.09s * *2015-11-06 23:30:29 (1.03 MB/s) - `index.html.1' saved [97308]* Does anyone met this situation before? thanks! my cf version is cf-release170 and the os is Ubuntu 12.04.1 LTS |

Maybe the security group block egress requests.

Thank you for your reply. since my cf-release version is 170, I checked and found it has not introduced the security groups concept for this CF version. 2015-11-07 17:04 GMT+08:00 Yitao Jiang <jiangyt.cn(a)gmail.com>: Maybe the security group block egress requests. |

I start with 197, but i think you can just verify the iptables of the warden container On Mon, Nov 9, 2015 at 10:49 AM, Youzhi Zhu <zhuyouzhi03(a)gmail.com> wrote:

CF 170 does not have application security groups, so that is not the issue. However, CF 170 is quite old now - we would be in a better position to assist if you are running a more recent version of cf-release.
