I am using Symfony2 on Digital Ocean Ubuntu 12.04.5 LTS (GNU/Linux 3.2.0-24-virtual i686).
Everything is working on my localhost, but do not work on Digital Ocean Server,
Here is error message when I try to register user in my web with Activation Email enabled :
Connection could not be established with host smtp.gmail.com [Connection timed out #110]
500 Internal Server Error - Swift_TransportException
and error stacktrace :
$this->_stream = #stream_socket_client($host.':'.$this->_params['port'], $errno, $errstr, $timeout, STREAM_CLIENT_CONNECT, stream_context_create($options));
if (false === $this->_stream) {
throw new Swift_TransportException(
'Connection could not be established with host '.$this->_params['host'].
' ['.$errstr.' #'.$errno.']'
);
Output from server terminal :
yusuf#xwzxc:~$ telnet smtp.gmail.com 465
Trying 74.125.130.108...
Trying 74.125.130.109...
Trying 2404:6800:4003:c01::6c...
telnet: Unable to connect to remote host: Network is unreachable
any help will be greatly appreciated.
Thanks
In order to curb spam and abuse, some new user accounts at DigitalOcean have their SMTP ports blocked by default. Unfortunately there are sometimes false positives. It sounds like this might have been the case for you. If you open a support ticket, the team would be happy to remove that block for you
As a temporary solution I have changed the smtp.gmail.com by the IP
You can get the IP by: ping smtp.gmail.com on the command line.

Local flywheel is not starting properly because it cannot open port 443 ("Heads-up!, Local's routing is having trouble starting" is the message).
I used netstats -o and nothing was using port 443.
The log from FlyWheel says:
bind() to 0.0.0.0:443 failed (10013: An attempt was made to access a socket in a way forbidden by its access permissions)
try this
run CMD as admin
type net stop http
There is an easy solution...
Preferences> Advanced> Router Mode > Localhost
It will work then.
You can watch this too

I make a server and request successfully in windows,then I put them to the linux which is the develop machine of company.
And I Got Connect Failed error when I run the clien.py. I have changed the host IP to localhost,0.0.0.0,127.0.0.1 and the IP of develop machine,but it doesn't work.
And I tried the docker inspect command,but the IPAddress is empty like "".
And I changed the port to 8500,8501,4321 and still got the error.
I tried make proxy to the company,the request returns a Name resolution failure error.So I think maybe the cause is the net of company?
Any answer would be very appreciate!

I developed my site with WordPress 4.5.3.I installed plugin WP-Mail-SMTP.I create mail account with my host tigrimigri.com.
with this setting
Secure SSL/TLS Settings
Username: Your Email Address
Incoming Server: freehost.tigrimigri.com
IMAP Port: 993
POP3 Port: 995
Outgoing Server: freehost.tigrimigri.com
SMTP Port: 25
Then I write this info at plugin WP-Mail-SMTP setting
But when I test email I get this error
The SMTP debugging output is shown below:
2016-07-02 12:21:04 Connection: opening to ssl://freehost.tigrimigri.com:25, timeout=300, options=array (
)
2016-07-02 12:21:04 SMTP ERROR: Failed to connect to server: Connection refused (111)

Please anyone help me.
I think you can not sent mail through freehost.tigrimigri.com

Can I use e-mail?
Sorry it is not possible yet to sent / receive e-mail through our server.
I am having k8s cluster on centos7.2 with 1 master and 2 slaves. The cluster is working fine as far as it is serving on port 8080 but when I tries to secure Kube-API server by using certificates, I felt into the above error after restarting the kube-apiserver service and it is continuously writing this error in my log file at /var/log/messages.
kube-apiserver is started as-
KUBE_API_ADDRESS="--bind-address=0.0.0.0"
KUBE_API_PORT="--secure-port=6443"
KUBELET_PORT="--kubelet-port=10250"
KUBE_ETCD_SERVERS="--etcd-servers=http://kube-master:2379"
KUBE_SERVICE_ADDRESSES="--service-cluster-ip-range=10.254.0.0/16"
KUBE_ADMISSION_CONTROL="--admission-control=NamespaceLifecycle,NamespaceExists,LimitRanger,SecurityContextDeny,ServiceAccount,ResourceQuota"
KUBE_ALLOW_PRIV="--allow-privileged=true"
KUBE_API_TLS_CERT_FILE="--tls-cert-file=/home/abc/server.cert"
KUBE_API_TLS_PRIVATE_KEY_FILE="--tls-private-key- file=/home/abc/server.key"
KUBE_API_TOKEN_AUTH_FILE="--token-auth-file=/home/abc/token.csv" </br>
I am accessing API server using kubectl command as
kubectl --v=4 --server="https://$ip:6443" --certificate-authority="./ca.crt" --token="abcdTOKEN1234" get nodes
After that I am getting following error-
2930 helpers.go:153] Connection error: Get https://$ip:6443/api: x509: certificate signed by unknown authority
2930 helpers.go:96] Unable to connect to the server: x509: certificate signed by unknown authority
I performed same steps on ubuntu 14.04 and are working fine. I am not able to figure out where exactly I'm missing. Can anyone knows where I am wrong ? Thanks in advance.
I'm trying to deploy Openstack Icehouse on Ubuntu Server 14.04 by following the official document. But after Keystone\Nova\Neutron\Glance were deployed, when I tried to launch a CirrOS instance by
nova boot -nic ... -image ... -flavor ...
, it failed.
The log in Nova client shows that:
The Neutron client(Yes, it's neutron. I guess there are interactions between them in booting) tried to connect with Neutron server to create a port on tenant's network.
But Neutron client set up the token-getting request using {username:neutron, password:REDACTED} to Keystone server and used that token to request for creating port to Neutron server.
Finally, the Neutron Server decided that that's an authentication problem.
I'm sure that I requested to create instance using tenant 'demo''s info($OS_TENANT_NAME, $OS_USERNAME, $OS_PASSWORD, $OS_AUTH_URL were properly set with 'demo''s value) by
source demoopenrc.sh
with demo's credential in that file.
Is that something wrong in the Neutron client's configuration or booting process? I paste a part of the neutron.conf here:
the Keystone setting
[keystone_authtoken]
auth_uri = http://controller:5000
auth_host = controller
auth_port = 35357
auth_protocol = http
admin_tenant_name = service
admin_user = neutron
admin_password = neutronpass
signing_dir = $state_path/keystone-signing
Since the Neutron client used 'neutron' user's credential for token getting, is there something wrong in this part?
