If the ClamAV service on different server, most probably it is not running

Hi there,

It is not clear to me what is not happening. :/

Is the clamd service not running, or is it running but the host is
refusing connections?

> and I am unable to connect scan an image file from my .net application.

If the service is not running, obviously you need to make it run.
Some ways to check that you can make connections to it are given in
the stackoverflow page to which you linked. Have you tried them?

If the service is running but you cannot connect to it, you need to
(1) make sure that it is listening in the way that you think it is
configured to listen, and (1a) make sure the nothing _else_ on the
same machine is trying to listen in the same way; (2) make sure that
you're trying to connect to it the way you think you're trying to
connect to it; and finally (3) make sure that there is nothing on the
machine which hosts clamd which is actively blocking connections, such
as a local firewall (which is very common on Windows boxes, as a quick
test you can simply disable the firewall completely but BE CAREFUL if
you do that).

You should be able to connect to the daemon manually from a command
line prompt. Search for PING in the _ClamAV_ documentation (this is
not the same as the 'ping' utility commonly used to quickly check a
network route is alive; PING is described in the clamd 'man' page).

Here's what happens when I send 'PING' to a clamd daemon here at my
place of work:

8<----------------------------------------------------------------------
mail6:# >>> telnet 192.168.44.7 3313
Trying 192.168.44.7...
Connected to 192.168.44.7.
Escape character is '^]'.
PING
PONG
Connection closed by foreign host.
mail6:# >>>
8<----------------------------------------------------------------------

From a 'bash' shell prompt on a mail server, I started the 'telnet'
utility to connect my terminal to the clamd server. That server is
configured to listen on a TCP socket because mail servers on our LAN
will be connecting to it (by default, clamd on Linux does not listen
to TCP sockets so I had to configure it to do that - I do not know if
that applies to Windows, because I have never run clamd on Windows).
It listens on port 3313 in my configuration so I have to connect to
that port using telnet (there's nothing special about that port; I
could have chosen more or less any otherwise unused port in the
thousands range; all that matters is that I connect to the port on
which the daemon is listening). After the TCP connection is
established, I see messages which are typical for a Linux system - you
will likely see different messages, but you can ignore that. Very
quickly, I typed the word 'PING' followed by the carriage return (or
ENTER) key, and almost immediately the reply 'PONG' appears. I need
to type quickly because there is a short timeout of a few seconds in
the configuration, and if I am too slow the daemon will unilaterally
close the connection. You can change the timeout if it too short.
After the exchange of PING and PONG, the daemon immediately closes the
connection and I again see the shell prompt.

If you cannot seem to establish any connection with a running daemon,
use a utility like 'tcpdump' or 'Wireshark' to trace the traffic.
There is plenty of documentation online about how to do that, there
should be no need to ask again here.

On a Win 10 machine:

1) Click START

2) Scroll down to and click on "Windows Administrative Tools

3) Click on "Component Services"

4) Expand "Services"

If the service is installed, even if not running, it will be listed
there. If it is listed, double click it and change "Startup Type" to
'Automatic'. Click on "Recovery 'on the top of the window you just
opened and make sure "Restart the Service" is the procedure to take if a
failure in the service occurs.

Good Luck!

The document to which you linked in your reply gives more than one
procedure. In my request for better information, I used the word
'exactly' six times.

Please give enough detail so that people on this list, who read your
messages but know nothing about your situation except what you write,
have the best chance of being able to help you.

If you are unable to tell us exactly what you did, perhaps you should
completely remove all the ClamAV software, then start again, but this
time make notes of everything that you do in your diary or workbook,
so that afterwards you will know what you have done, and can tell us.

Is your server software still supported? Mainstream support for
Windows Server 2012 R2 ceased in September 2018:

Hi Bijay,

ClamAV does not presently have the feature to create and start Windows Services. There is a derivative project called clamav-win32 made by Gianluigi Tiesi which does provide this feature: https://github.com/clamwin/clamav-win32

We've relatively recently received Gianluigi's blessing to incorporate features from clamav-win32 into the main ClamAV project, to include support for starting clamd as a Windows Service. This isn't one of the tasks we've prioritized for 0.103 dev though, so it's unlikely that you'll see it in ClamAV this year.

I hope this helps.

Best,
Micah
