I have done a fresh installation with Ubuntu 18 + Asterisk 16 + FreePBX 15
But I found by default it is not logging unanswered call, should I add “unanswered = yes” in res_odbc_custom.conf myself?
or there is option via FreePBX web GUI?

As an async bidi streaming server, I expect ServerAsyncReaderWriter::Write is async, the actual work(say tcp_write/flush) would be done mostly in the background(maybe the default executor).
But actually, perf(perf record -F 99 -p xx -g -- sleep 90) shows ServerAsyncReaderWriter::Write directly calls tcp_write, and the default executor is almost idle all the time.
Walking down the source along ServerAsyncReaderWriter::Write -> Call::PerformOps -> Server::PerformOpsOnCall -> CallOpSet::FillOps -> grpc_call_start_batch -> ~ExecCtx -> ExecCtx::Flush -> grpc_combiner_continue_exec_ctx, I don't find any chance to give work to others...
Is this by design, or what's wrong?
This looks to work as intended. gRPC C++ tries to use the given threads as much as possible. It uses another threads such only when it has to.
I'm just trying to do a POC test with Telium's HAAst before we offer it to a customer, but I've stalled before I start the haast daemon. Currently I have a single VM with Ubuntu 16.04 LTS with Digium's basic Asterisk 13 installation. I've configured haast.conf, it seems good, but I cannot start haast daemon, it stops after a few seconds. Here is the relevant log output:
General, HAAst version 2.3.2.1 starting as daemon under process ID 2409
Controller, Local peer HAAst state changing to service start
License, License file not found. Switching to Free Edition
General, Settings contained 0 information; 0 warning; and 0 error messages.
Asterisk Controller, Unable to located executable to control Asterisk
Controller, Local peer HAAst state changing to service stop
Controller, Stopped
General, HAAst terminating with exit code 158 (failure to find asterisk control files) after running for 2 seconds
It seems, haast misses the event controller to start Asterisk daemon, unfortunately it didn't contain the installation package. I've tried to make these files (asterisk.start & asterisk.stop) based on the other sample event files, I've set the executable bit, I've wrote the shebang to the first line based on the installation guide, but nothing helped.
Is somebody experienced about this case?
Thanks, Zsolt
This error means that High Availability for Asterisk (HAAst) is unable to find the service/executable file needed to control Asterisk. Since the 'distribution' setting in the [asterisk] stanza of the haast.conf file is it to 2 (Digium Asterisk), it means there's a problem with the Asterisk service file.
Ubuntu 16 uses systemd so have you installed Digium's asterisk.service (systemd) file? If you chose to install an initd service file for Asterisk instead then you may have to explicitly tell HAAst which to look for. If you installed neither then that's your problem. The maker of HAAst (Telium) has a support forum where this topic is addressed (click here).
The pre and post Asterisk event handlers are available in the commercial versions of HAAst only - so that won't help (but it's also the wrong way to solve the problem). There are also a few Ubuntu specific topics on the support forum https://www.telium.io/haast in case that helps.
If you can't find an Asterisk systemd service file here's a sample:
[Unit]
Description=Asterisk PBX and telephony daemon
Documentation=man:asterisk(8)
Wants=network.target
After=network.target
[Service]
Type=simple
User=asterisk
Group=asterisk
ExecStart=/usr/bin/asterisk -f -C /etc/asterisk/asterisk.conf
ExecStop=/usr/bin/asterisk -rx 'core stop now'
ExecReload=/usr/bin/asterisk -rx 'core reload'
[Install]
WantedBy=multi-user.target
Just save that file as 'asterisk.service' and place in /etc/systemd/system/ and ensure permissions match other service/unit files.
Haast configuration is missing or not correct:
Unable to located executable to control Asterisk
I am working on some application using Qt 5.7.0 GCC 64bit on Linux workstation 4.4.0-36-generic #55-Ubuntu SMP Thu Aug 11 18:01:55 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux which among other things shows available WiFi networks from selection, the core code is here:
void UeWiFiDiscoveryTask::run()
{
QList<QNetworkConfiguration> networksList=this->ueNetworkConfigurationManager()->allConfigurations();
QList<UeWiFiNetworkRecord*> wifiList=QList<UeWiFiNetworkRecord*>();
foreach(QNetworkConfiguration network,
networksList)
{
if(network.isValid()&&network.bearerType()==QNetworkConfiguration::BearerWLAN&&network.state()==QNetworkConfiguration::Discovered)
{
qDebug() << Q_FUNC_INFO
<< network.state();
wifiList.append(new UeWiFiNetworkRecord(new QImage(":/images/testWifi.jpg"),
network.name()));
emit this->ueSignalWiFiFound(*wifiList.last());
} // if
} // foreach
emit this->ueSignalWiFiDiscoveryFinished(wifiList);
} // run
The code runs on separated thread and it works perfectly. However, I am reading Qt Bearer Management docs and I cannot find the way, how to distinguish between Free WiFi and encrypted/protected WiFi. How do I add such functionality?
P.S.: I am aware this is how-to question and I am ready to gain some negative points, however, I've been reading the docs for several days and I am lost!
Assuming this is a system with NetworkManager then QNetworkConfiguration::identifier() will return the D-Bus ObjectPath of the NetworkManager configuration item.
I.e. you could use QtDBus to call the org.freedesktop.NetworkManager.Settings.Connection.GetSettings() method on that object which I think should include the information you are looking for
I connect to 8 different unix servers from Windows, using connection type 'SSH' in putty. I use the same username/password for each server.
Currently when I need to change passwords (every 60 days), I need to open putty, select the session I want to connect to, type my current password (in the putty window that opens), type "passwd", enter my current password, and then enter my new password.
Then I exit and repeat the process 7 times.
How can I convert this to an automated process where I simply need to supply a script/batch process with my old and new password?
Here is how I automated the process:
Download and install ActiveTCL Community Edition (download the 32 bit version, even if you are on 64 bit windows, as the 64 bit version does not have "Expect" which is what you need to run the automated script)
Open the tclsh85 executable that was created by the install
Run this command "teacup install Expect" (note, this is case sensitive. You may need to setup special http settings if you receive an error and/or are on vpn or using a proxy)
Download Putty's "plink.exe" and either place it in the bin directory of ActiveTCL (default install directory is "C:\Tcl\bin") or alter your "Path" environment variable to include the path to this executable (wherever you downloaded plink.exe). This is the command-line version of Putty which your script will use.
Anywhere on your drive, create a text file named "servers.txt" with a list of the servers (one per line). They should all share the same password, as the script will login to all of them with the same password (that you supply), and change the password to the one you supply.
In the same directory as "servers.txt" create a new text file called "ChangePassword.tcl" (or whatever you want to call it, but be sure its file type is "tcl"). Right click the file and edit in notepad (or whatever text editor you prefer) and paste this script in it.
package require Expect
exp_log_user 0
set exp::nt_debug 1
proc changepw {host user oldpass newpass} {
spawn plink $host
log_user 0
expect {
"login as: " { }
}
exp_send "$user\r"
expect "sword: "
exp_send "$oldpass\r"
expect "\$ "
exp_send "passwd\r"
expect "sword: "
exp_send "$oldpass\r"
expect "sword: "
exp_send "$newpass\r"
expect "sword: "
exp_send "$newpass\r"
set result $expect_out(buffer)
exp_send "exit\r"
return $result
}
label .userlbl -text "Username:"
label .oldpasslbl -text "\nOld Password: "
label .newpasslbl -text "\nNew Password: "
set username "username"
entry .username -textvariable username
set oldpassword "oldpassword"
entry .oldpassword -textvariable oldpassword
set newpassword "newpassword"
entry .newpassword -textvariable newpassword
button .button1 -text "Change Password" -command {
set fp [open "servers.txt" r]
set file_data [read $fp]
close $fp
set data [split $file_data "\n"]
foreach line $data {
.text1 insert end "Changing password for: $line\n"
set output [changepw $line $username $oldpassword $newpassword]
.text1 insert end "$output\n\n"
}
}
text .text1 -width 50 -height 30
pack .userlbl .username .oldpasslbl .oldpassword .newpasslbl .newpassword .button1 .text1
Save the script and then launch the ChangePassword.tcl file.
Here is a picture of what it looks like when you open the ChangePassword.tcl file:
The rest should be self explanatory. Note the program does not output when your password change was successful but it will tell you when it fails. Also note, this was my first tcl script (and first time using Expect) so the script is by no means "optimized" and could probably be improved but it gets the job done. Feel free to edit, or make suggestions/improvements.
Sounds like you want Expect, an extension of TCL that can mimic typing at a keyboard for a console application. See the examples for how to do this.
Now there is something you've written that worries me:
I connect to 8 different unix servers, using connection type 'SSH' in putty. I use the same username/password for each server.
Why aren't you using SSH keys for automating the logon?
Great article! Just elaborating on step-3. Please note the commands to provide Proxy server information in case "teacup install Expect" fails due to connectivity issue:

I have this Google Dart test program:
#import('dart:io');
main() {
var s = new HttpServer();
s.defaultRequestHandler = (HttpRequest req, HttpResponse res) {
res.statusCode = 200;
res.contentLength = 4;
res.outputStream.writeString("sup!!");
res.outputStream.close();
};
s.listen('127.0.0.1', 80);
print('its up!');
}
It works fine on Chrome and Firefox, I get the sup -messages.
However, as soon as I try Apache Bench against it, it hangs (ab hangs):
Z:\www>ab -n 1 -c 1 "http://127.0.0.1/"
This is ApacheBench, Version 2.3 <$Revision: 655654 $>
Copyright 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/
Licensed to The Apache Software Foundation, http://www.apache.org/
Benchmarking 127.0.0.1 (be patient)...apr_poll: The timeout specified has expired (70007)
You can find ab by installing Apache HTTP server and it will be located under the bin folder.
On a side note: is there some other benchmarking tool similar to ab that I could possibly use (and does not hang)?
It could be a problem with the contentLength. You wrote 4, but the actual content length is 5. For instance, if ab saw the contentLength, it might read 4 characters and wait for the connection to close. However, the connection probably won't close because the server is waiting to write the last character. The client and server are each waiting for something, resulting in deadlock.
