Connection to remote ip to 4999 port failed

[v.yarymov]

Hello.

I try connecting to remote host to 4999 port for remote management of managers (WEB format of console window).
But browser returned error: ERR_CONNECTION_REFUSED.
I used pmon_query function for getting statuses of remote hosts, but function returned error: tcpOpen, timeout expired.

Firewall on hosts not using, ping command is good.

Code:

int port = 4999;
string host = "s2012a";
dyn_dyn_string ddsResult;
pmon_query("##MGRLIST:STATI", host, port, ddsResult, false, true);
DebugN(ddsResult);

Hi,

If you are not localhost, by default you cannot access pmon via TCP.

See

qthelp://wincc_oa/doc/Notes/Note-40.htm

ohh..WinCC is a pain and suffering
Do You know, maybe there are other things that can see info from remote managers?

[adaneau]

I mean, you can change this but you need to add some whitelist

look at link from help

Sorry.. I cannot find this documentation. I very small time working with WinCC and dont know about much things.. Where I can see it?
I try find something about tcpOpen in WinCC OA Online Help, but not finded needed information.

For details why accessing the Process Monitor from a remote machine is blocked please have a look at the following Forum thread
https://portal.etm.at/index.php?option= ... 27&id=1598

In the thread you can also find information for the configuration of the Process Monitor.

Thank Alexandre, and thank Leopold.

I added in config files

[pmon]
localAddress = ""

Yes, all working. Also need looking on firewall sometimes
