Can any one help me on this why its doing like that
If roundcube able to access dovecot without problem, maybe firewall issue. Please provide iptables-save result, and make sure dovecot listen to WAN interface.

I have a VPN configured by ovpn in my mikrotik that already works, but whenever I connect both by android and Windows, I get the error:
ovpn,debug,error,,,,,,,,,l2tp,info,,debug,,,critical,,,,,,,,,,,,,warning duplicate packet, droppin
On console and terminal:
I have already looked for the official forum of mikrotik but neither has no clear answer or a definitive solution.
My goal is to remove this error from my terminal and from my console log.
My current setting:
OVPN SERVER:
PPP PROFILE:
#Edit:
After contacting support, I got this error message to have no impact on the VPN. Below is the email from Mikrotik Support:
Email:
"Hello,
This error message does not have any impact on the VPN connection
establishment, it simply warns you that the client sent duplicate
message which some client software (for example Windows) do.
Best regards, Emils Z."
Thank you all for your help.
I would advise that this is probably a bug in the OVPN implementation on Mikrotik's side. Please log a support ticket with them, and provide the supout.inf file as per the usual process.
Please see this link on how to make the support info file:
https://wiki.mikrotik.com/wiki/Manual:Support_Output_File
In short, open winbox, click the make support file on the left, and then go to files and download the file to your pc. Then attach this file to the support ticket.
I'm getting a weird behavior on my Asterisk.
Calls are dropped after 15mn.
I'm getting the following error on the log file:
NOTICE[6301] chan_sip.c: Failed to authenticate on INVITE to '<sip:41907736445#188.32.64.1>;tag=ef7143klc9'
I'm using Asterisk Realtime. Calls a received from an operator and forwarded to external numbers throught an outbound trunk provided by anther operator.
Thanks in advance
In your sip.conf, try setting qualify=yes or keepalive=yes globally or for the trunk. Make sure to reload or just restart the service.
What version of Asterisk are you running?
Some carriers may send "confirmation" invite every X minutes.
You can see more by enable sip debug
Also if exactly at 15 min calls get dropped, then i would check the firewall to see whether there is timer set there that closes the connection after 15 min. I am speaking from experience.
In my Solaris server, I have an HTTP Server which handle many incoming connections. In my server logic, it closes connection from client manually so that many TIME_WAIT status appear when I call command netstat -an in my server.
So that I change the tcp_time_wait_interval to 10 second with command:
ndd -set /dev/tcp tcp_time_wait_interval 10000
But I read from user guide, it says : "Do not set the value lower than 60 seconds".
Does anyone know why Oracle recommend that?
The user guide URL is : http://docs.oracle.com/cd/E19455-01/806-6779/chapter4-51/index.html
Was told my Oracle engineer with a very heavy trans load in thousands/sec can set to as low as 10 ms on Solaris 11/11.1
I'm a veteran of Asterisk 1.4 and am looking to build a new application on Asterisk 11 (which is currently beta, but is planned to be LTS release some time before I need it.)
I can't get Asterisk Manager Interface on 11 to send me any events. (Now, obviously, in production, I need to cut down these AMI rights drastically, but as I'm exploring I've opened the firehose, if you will.)
manager.conf looks like this:
[general]
enabled = yes
port = 5038
bindaddr = 127.0.0.1
[manager]
secret = squirrel
deny = 0.0.0.0/0.0.0.0
permit = 127.0.0.1/255.0.0.0
read = all
write = all
I then use telnet to try to get in and explore the event stream:
$ telnet localhost 5038
Trying ::1...
telnet: connect to address ::1: Connection refused
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
Asterisk Call Manager/1.3
Action: Login
Username: manager
Secret: squirrel
Events: on
Response: Success
Message: Authentication accepted
Event: FullyBooted
Privilege: system,all
Status: Fully Booted
...and there it sits, not moving, no matter what I actually do with the system. I've also tried using the Event manager action with EventMask: on to try to get something out of it; the command is accepted, but nothing changes. It will happily respond to any other actions I send it, though.
Any leads? This sort of thing worked fine under 1.4, and I'm not finding anything in any documentation suggesting I'm doing something wrong. I suppose the next thing to try is 1.8...
(There is little else in /etc/asterisk; I'm using example configs only for reference. This is as minimal as we get...)
It's may be bug in Asteriks / FreePBX. I had same situation, and my API php script didn't receive any events from AMI.
For fix this bug, you must install "Conferences" module and restart Asterisk from SSH: service asterisk restart
I just tested this with the latest 11 from subversion using your configs. I see events being generated. For example, executing this from the CLI:
*CLI> channel originate Local/Foo application Bar
While invalid, will cause some events to be spit out to the manager interface.
I have CoreFTP configured for localhost and the next code:
JSch.setLogger(new MyJschLogger()); //class for console output
Session session = jsch.getSession("user", "localhost", 21);
Properties config = new Properties();
config.put("StrictHostKeyChecking", "no");
session.setConfig(config);
session.setPassword("password");
session.connect();
when program achieves connect(), two messages appear at console output:
INFO: Connecting to localhost port 21
INFO: Connection established
...and nothing more happens. After some minutes, connection is closed by foreign host exception appears.
Why?
Thanks for all!
Port 21 is the normal port for FTP. JSch is only an SSH client, with support for SFTP in the ChannelSFTP class. JSch knows nothing about FTP (and SFTP is unrelated to FTP, other than by name and that it allows similar things).
You need to setup your server to use the SSH protocol (usually on port 22, but you can use any port, as long as you use the same port on the client). See the documentation - I think you have to check the SSH check box.
Also, if your code is nothing more than what you posted, then nothing more than connecting will happen. To transfer files, you will need to open a ChannelSFTP, and issue the right commands (e.g. call one or more of the put/get methods).
I also faced the similar issue:
"ERROR 2016-04-27 15:05:16,489 [CollectionThreadPool-0] com.dell.supportassist.collector.cli.executor.SSHExecutor: com.jcraft.jsch.JSchException: connection is closed by foreign host"
In my case, channel was getting closed randomly. And when we are trying to re-connect the channel then it was not re-connecting and failing.
This was happening due to looping logic while connecting, so I tried to connect the session without channel by calling method connectWithoutOpenChannel instead of connectinternal(). This resolved my issue.
