[asterisk-users] utils.c: fwrite() returned error: Broken pipe how to solve it ???
Dear all,
I want to make call through socket i have set code given below:
#!/usr/bin/perl -w
use IO::Socket::INET;
sub asterisk_command ()
{
# my $command=$_[0];
my
$ami=IO::Socket::INET-new(PeerAddr='127.0.0.1',PeerPort=5038,Proto='tcp')
or die failed to connect to AMI!;
print $ami Action: Login\r\nUsername: lite\r\nSecret:
4003\r\n\r\nAction: Logoff\r\n\r\n;
}
asterisk_command(Channel: DAHDI/27/7702009896\r\nExten: s\r\nContext:
outbound\r\nCallerID: 20048645\r\nPriority: 1\r\nMaxRetries: 2\r\n);
Whenever i execute that code i'm get following error

AMI is a *two-way* protocol. You mustn't just fire in a bunch of commands
and close the socket!
The reason Asterisk reports the fwrite() error is because you have closed
the socket before it had a chance to send you the responses.
What you need to do is this:
1. Connect to the AMI port.
2. Read the one-line greeting message that Asterisk sends you. It will tell
you the version of the protocol (which might be of interest if you wanted
to be compatible with different versions of Asterisk).
3. Send the Login action with username, secret and terminating blank line.
4. Read the response lines from Asterisk until it gives you a blank line.
5. Send whatever command you want it to do, and go back to step 4.
6. When you have done the commands you want, send the Logoff action.
7. *** READ THE RESPONSE TO THE LOGOFF
8. Close the socket.
If it helps. Here is similar piece of code I wrote to query pri spans.
Note carefully the setting of $/ in two places, and the inclusion of
Events: off to avoid responses getting confused by asynchronous events.
==
#!/usr/bin/perl
use IO::Socket;
my $numspans = 4;
my $host = 'localhost';
my $login = Action: login\r\nUsername: \r\nSecret: \r\nEvents:
off\r\n\r\n;
$/ = \r\n;# reads a single line for signon banner
my $s = IO::Socket::INET-new($host:5038) or die can't connect to $host:
$!\n;
my $banner = $s; # read the banner
#my $line = ('-' x 78).\n;
#print $banner,$line;
$/ = \r\n\r\n;# reads a complete response ending in a blank line
print $s $login;
my $resp = $s;
#print $resp,$line;
my @spans;
foreach $span (1..$numspans) {
print $s Action: Command\r\nCommand: pri show span $span\r\n\r\n;
$resp = $s;
#print $resp,$line;
if ($resp =~ /Status: (.*)\n/) {
$status = $1;
} else {
$status = 'Unknown';
}
$spans[$span-1] = Span $span status = $status\n;
}
print $s Action: Logoff\r\n\r\n;
$resp = $s;
#print $resp,$line;
close $s;
# go on to display the results from @spans

Cheers

Broken Pipe is a bit misleading because it can refer to other modes of
connection besides pipes (although that certainly is the most common case
where you would see it). It just means something tried to write to a stream
that has already been closed.
In this case, AMI is trying to send back a response *after* you have already
closed the socket. To avoid the error, you need to see if there is any data
waiting to be read from the socket, and then read it. (Then, having gone to
the trouble of actually reading it, you may as well at least do a simple
regular expression match to ensure that what you were expecting to happen
actually happened.
Also, as Asterisk runs on Unix-like systems, you don't really need the
Microsoft-style \r\n line endings. Just an ordinary Unix-style \n on its own
will suffice. It even saves a few CPU cycles on the far end (not that you'll
ever actually notice from within an interpreted script).

Text-based internet protocols (e.g. SMTP, FTP, etc) canonically use \r\n as a line terminator, and AMI does likewise. It may well accept commands with just \n as a line termiator (I haven't checked), but it certainly sends \r\n to terminate lines that it outputs. IMHO, it's good to adhere to the same convention in both directions.

I want to run am interactive menu before or within the normal voicemail dialogue to run a script based on the subscriber selection. My point is to get use from the authenticated password that provided by user to go though his voicemail to access this new feature as well! If not, is there a way to use the same authentication to access this menu a way from voicemailmain application? Thanks. If you are trying to use dialplan logic directly, you could use the function VM_INFO to compare a users password with what they have entered. You would basically be writing your own code before you ever went to voicemail to have them type their password, then save that to a variable and compare with what VM_INFO shows as the correct password. You could also use an AGI script as detailed here: http://www.voip-info.org/wiki/view/Asterisk+authenticate+using+voicemail+passwords __ This email has been scanned by the Symantec Email Security.cloud service.

Re: [asterisk-users] Using sqlite3 for CDR logging
Thanks for the feedback. I read someplace that the Berkeley DB was wicked fast and allowed for much higher concurrency. The only problem is that I have no idea how to implement it into Asterisk.

Has anyone ever benchmarked this to quantify just how much faster sqlite3 is? Are there any drawbacks to using it? Lack of multi-user concurrency is the big one. At the risk of encouraging database contests on the list, have you tried using PostgreSQL instead? It's a gross generalisation, but In my experience, PG handles writes better than MySQL, which in turn tends to handle reads a little faster than PG - assuming both are in 'out of the box' (i.e. unoptimised) conditions. If you wanted to stick with MySQL, you might want to have a go at optimising it - there are quite a few scripts knocking around the web which run a set of queries on your data and suggest optimisations to apply. And others have said, running the DB on a separate host is never a bad thing, and ideally on SSDs or RAM storage if you can. Spinning disks are often the bottleneck with large data sets.
