I am fairly new to python and seem to have gotten ahead of myself. I
am trying to write a Windows service that will return the current
number of Citrix sessions to a client. This service will run on my
Citrix servers for usage tracking purposes.
The service itself seems to function properly, it starts, stops, logs
to the event viewer, etc. The problem seems to be with the portion
where it either waits to be stopped or waits for remote...

I have a list of IP addresses I am testing with socket.gethostbyaddr().
For the most part, I am able to get a hostname returned to me when I
run gethostbyaddr(). I am also hoping this will allow me to tell if a
computer is up or down. However, in my environment, I am finding that I
am able to get a hostname even though I am unable to actually ping that
server (when I ping a server i like this, I get 'request timed out'

Hello,
Please Help.....
I have been working with some tcp/ip socket communication within a C#
program recently. Basicly, I have a program (myProblemProgram) that has a
socket connected to another program for information passing. Upon receiving
a particular "command" from the the information passing program,
myProblemProgram will launch a separate thread to do individual communication
with another file transfer program. The thread...

Hi
Since yesterday about 11.00 CET the gethostbyaddr function doesn't seem
to be working. All I get is the IP address back. Is this something
general to all PHP users or is this specific to my server?
Thanks
BTW what's the difference between comp.lang.php, alt.php and
alt.comp.lang.php, shouldn't these groups be merged?

Hi,
In an attempt to create a full-blown webcrawler I've found myself
writing a wrapper around the Socket class in an attempt to make it
completely async, supporting timeouts and some scheduling mechanisms.
I use a non-blocking approach for this, using the call to 'poll' to
support the async mechanism - rather than the 'begin' and 'end'
functions. I already found that connecting doesn't set the
"isconnected" variable correctly...

When there is no rDNS record on an IP address, then it might take a while for
the reverse lookup to timeout. I'm thinking of how on a tracert you can
observe the delay.
If so, then calling gethostbyaddr() can delay the serving of the web page,
right? Because gethostbyaddr() is not forked into a separate process. So I
suppose I'd need to call gethostbyaddr() as the very last task for a script.
Does that sound right? Or is there another...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
