Hi all,

I have just noticed that my sockets are taking ages to open. I then realised it is only since I downloaded the new version. I have used this code on mIRC 6.35 and on mIRC 7.1 and got two vastly different results.

Code:
alias test_socket {
  set -e %socket_time $ticks
  sockopen test_socket www.google.com 80 
}
on *:sockopen:test_socket:{ 
  echo $color(info) -a It took  $calc(($ticks - %socket_time) / 1000) seconds for $sockname to open.
  unset %socket_time 
  sockclose $sockname
}


mIRC 7.1 returned It took 15.031 seconds for test_socket to open.

mIRC 6.35 returned It took 0.078 seconds for test_socket to open.

I find it very troubling, and wonder what the problem could be.

Can you identify whether the connection is successful or not? What error (if any) is reported if you use this code?

Code:
alias test_socket {
  set -e %socket_time $ticks
  sockopen test_socket www.google.com 80 
}
on *:sockopen:test_socket:{
  echo -a Time: $calc(($ticks - %socket_time) / 1000) seconds
  unset %socket_time 
  if ($sockerr > 0) {
    echo -a Connection failed: $sockerr / $sock($sockname).wsmsg
    return
  }
  echo -a Connection successful
  sockclose $sockname
}

Can't reproduce it here.
7.1 is slower, but not noticable.

Do you have the UPnP settings enabled?

Can't reproduce this either with OP code, it makes sense to me that the connexion is successful since it get a result

The ON SOCKOPEN event will be triggered even if the connection fails. You must check $sockerr to find out.

I can confirm that the socket does open successfully.

mIRC 7.1 Returns

Time: 15.047 seconds
Connection successful

mIRC 6.35 Returns

Time: 0.031 seconds
Connection successful

You didn't mention if you have upnp enabled. That is most likely the cause.

I have not been able to reproduce this so far. The connection is immediate in my tests. Which version of Windows are you using?

UPnP is unlikely to be the cause of any issues since UPnP is only used when mIRC needs to listen for an incoming connection not when opening an outgoing connection. However you can try disabling UPnP in the Options/Connect/Options/Ports dialog to see if that helps.

Also in the Ports dialog, if you disable the Port Range options, does that help?

Hi,

Sorry for taking so long to reply.

I am using Windows XP Pro

I went to options/ports in 7.1 and could not find how to disable the range. I have enclosed a screenshot below, unless you want me to clear both boxes? not sure what you meant.

Also disabling uPNP had no effect!

Even if it is upnp why is mIRC6.35 not affected?

Many thanks.

version 6.35 has no upnp support, that is why we were talking about it.

Yes, if you could uncheck all boxes in the "Port Range" section and then let us know if that helps.

Have you tried disabling any anti-virus or firewall software that may be hampering mIRC in the name of security?

It could be you've added mIRC 6.35 to a whitelist previously.


Spelling mistakes, grammatical errors, and stupid comments are intentional.

Hi starbucks,

I disabled windows firewall, and my AV, still the same result. I did the same with my routers firewall etc.

Take in mind mIRC 6.35 opens sockets instantly.

If it helps to debug I am happy for you to connect to my machine.

-

Time: 15.047 seconds
Connection successful

Its always seems to be round the 15 second mark for some reason.

Maybe it's an option to use a network analyzer like Wireshark, to see what the difference in behaviour is between 6.35 & 7.1.

I also noticed this with my HTTP-Check script (checks an URL and tells me the title, or whether it redirects to a potentially dangerous site).

6.35 was pretty quick, 7.1 takes considerably longer. I also noticed this with /dns queries, so I think it might be related to that (remember that IPv6 is now available from within mIRC).

UPnP is disabled, all ports in the configuration are unchecked, and I don't have a firewall that could affect this.

Could you tell us the result when you execute the following code, both in 6.35 and in 7.1

Code:
alias test_socket {
  set -e %socket_time $ticks
  sockopen test_socket www.google.com 80 
}
on *:sockopen:test_socket:{
  echo -a Time: $calc(($ticks - %socket_time) / 1000) seconds
  unset %socket_time 
  if ($sockerr > 0) {
    echo -a Connection failed: $sockerr / $sock($sockname).wsmsg
    return
  }
  echo -a Connection successful
  sockclose $sockname
}


Usage /test_socket

Code:
Time: 0.172 seconds
Connection successful


I did some testing with /dns using the same piece of code (except /dns instead of /sockopen, and on DNS instead of on SOCKOPEN). The first request for a domain takes 10+ seconds, the following ones are quick (cached?)
I guess its the same thing when doing /sockopen domain.tld instead, since someone needs to resolve the IP first.

Which obviously means his tests should be as fast as in 6.35 when he uses one of the IPs of www.google.com
We'll see...
