Anyone have an idea about how to collect client server stats using the Powershell client on machines that are on an intranet that blocks port 1984, and send it out to our external xymon server located in a different part of the country? The intranet network doesn't want to open any additional ports to allow the traffic out.

any possibility to send something from intranet to the world outside? creating webpage, send by sftp or scp? This could be done by cron and xymon could analyze this data then.

The Powershell client can connect to the Xymon server using TCP port 1984 as default, but can also connect using HTTP or HTTPS with/without user/password. You likely have port 80 or 443 open. Here are Word doc details:
HTTP is an alternate method. It can be used if you have xymoncgimsg.cgi running on the web server on your Xymon server – see https://www.xymon.com/help/manpages/man8/xymoncgimsg.cgi.8.html. The web server running the CGI can be configured for SSL (i.e. HTTPS) and / or authentication – XymonPSClient supports basic authentication and SSL. If you require authentication, the <serverHttpUsername> and <serverHttpPassword> elements should be configured. If you are using HTTP and transmitting over unsecure networks (e.g. the internet), it is strongly recommended to enable SSL, authentication and disallow HTTP connections.
ServerHttpPassword encryption If <serverHttpPassword> is set, the Xymon client will encrypt the password if it is not encrypted and remove the plain text password from the configuration file, overwriting with the encrypted password. The Xymon client will prefix the encrypted password with ‘{SecureString}’, so it is easy to tell if the client has attempted to encrypt the password or not. This is done using the .NET SecureString functions, which means that the encryption is unique to the server and user. This means that once the password has been encrypted, you cannot use the same xymonclient_config.xml on another server. It also means that if you have been testing by running XymonPSClient from a command prompt, and this encrypts the password, when you run XymonPSClient as a service it will not be able to decrypt the password unless the service is running as the same user. In both scenarios, replacing the encrypted password with the plain text password and re-starting Xymon will cause the password to be re-encypted.

Thanks for this info. From reading the man page it seems like this is enabled by default. Looking at the XymonPSClient.doc it says to change the <servers> element to <serverUrl> in order for the client to send over HTTP(s). Do I simply put *https://*servername.com in the xymonclient_config.xml if my intent is to use port 443?

I've configured one of my PSclients to test this HTTPS functionality, and it indeed does try to send data over port 443. But the client logs say that my Xymon server is timing out. Is there a specific server url path that I need to be using? The documentation doesn't give any example.

Alas, I am unable to help further, as my InfoSec allows port 1984, and not 80 or 443 to Xymon, so I don't have http running.

So I'm pretty sure I have the client configured correctly. It's trying to connect to my server url with the correct user/pass and it's encrypting, but it's getting a timeout. The URL I'm using is https://myservername.com/xymon-cgi/xymoncgimsg.cgi
On the server: I've copied the xymoncgimsg.cgi from ~/xymon/server/bin/ to ~/xymon/cgi-bin/ I then chown'd it so xymon is the owner and group and executable, just like the other files in that directory.
I think the server needs to be told that the xymoncgimsg.cgi is ok to process. Do I need to define something in the xymonserver.cfg? What am I missing here?

Anyone have xymoncgimsg.cgi functioning on their server and successfully receiving PSclient data over HTTPS? The documentation for this is vague and doesn't specify how to make it work. Any specifics would be greatly appreciated.

Hi Kris
Yes, I have it working. As you say, the URL needs to include the full path to xymoncgimsg.cgi.
All xymoncgimsg.cgi does as far as I can tell is relay the message(s) received over HTTPS via TCP to localhost port 1984 (which is what the man page says as well). So you need that listening (which by default it will be).
I don’t recall making any other config changes to make this work (aside from Apache etc to sort out the authentication).
I suspect the time out is waiting for the response – when you submit data to Xymon, you normally get the client local config back from the server. This comes back via the HTTPS response. There is a timeout setting – sorry I forgot to document it in the table in the Word doc – serverHttpTimeoutMs – which defaults to 100000 milliseconds – i.e. 100 seconds. This is the time it waits for the response from the server. 100 seconds is pretty generous unless you’re traversing particularly slow VPNs or saturated connections. You can override this in the xymonclient_config.xml file.
I’m assuming you’re getting this message:
" Connecting to $($url), body length $($body.Length), timeout $($script:XymonSettings.serverHttpTimeoutMs)ms"And then this one (with a timeout exception):
" Exception connecting to $($url):`n$($_)"And not either of these:
" FAILED, HTTP response code: $($response.StatusCode) ($statusCode)"or " Received $($output.Length) bytes from server"

The web server running the CGI can be configured for SSL (i.e. HTTPS) and / or authentication – XymonPSClient supports basic authentication and SSL. If you require authentication, the <serverHttpUsername> and <serverHttpPassword> elements should be configured. If you are using HTTP and transmitting over unsecure networks (e.g. the internet), it is strongly recommended to enable SSL, authentication and disallow HTTP connections.
ServerHttpPassword encryption If <serverHttpPassword> is set, the Xymon client will encrypt the password if it is not encrypted and remove the plain text password from the configuration file, overwriting with the encrypted password. The Xymon client will prefix the encrypted password with ‘{SecureString}’, so it is easy to tell if the client has attempted to encrypt the password or not. This is done using the .NET SecureString functions, which means that the encryption is unique to the server and user. This means that once the password has been encrypted, you cannot use the same xymonclient_config.xml on another server. It also means that if you have been testing by running XymonPSClient from a command prompt, and this encrypts the password, when you run XymonPSClient as a service it will not be able to decrypt the password unless the service is running as the same user. In both scenarios, replacing the encrypted password with the plain text password and re-starting Xymon will cause the password to be re-encypted.

Thanks for the reply Zak. After my brain chewed on the problem for a day I woke up at 2am and was able to figure it out. I did some Googling regarding Apache and CGI scripts and all I needed to do was to edit the default cgi-bin path in one of apache's conf files and restart Apache. /etc/apache2/conf-enabled/serve-cgi-bin.conf defines /usr/lib/cgi-bin/ which is an empty directory on my server. I pointed it to my /xymon/cgi-bin/ directory where the scripts live and everything suddenly worked. I'm writing up my own how-to now. This feature is great for sending remote system data over 443. I'll be using it a lot moving forward. Thanks for the PSclient!

Hi Kris
Yes, I have it working. As you say, the URL needs to include the full path to xymoncgimsg.cgi.
All xymoncgimsg.cgi does as far as I can tell is relay the message(s) received over HTTPS via TCP to localhost port 1984 (which is what the man page says as well). So you need that listening (which by default it will be).
I don’t recall making any other config changes to make this work (aside from Apache etc to sort out the authentication).
I suspect the time out is waiting for the response – when you submit data to Xymon, you normally get the client local config back from the server. This comes back via the HTTPS response. There is a timeout setting – sorry I forgot to document it in the table in the Word doc – serverHttpTimeoutMs – which defaults to 100000 milliseconds – i.e. 100 seconds. This is the time it waits for the response from the server. 100 seconds is pretty generous unless you’re traversing particularly slow VPNs or saturated connections. You can override this in the xymonclient_config.xml file.
I’m assuming you’re getting this message:
" Connecting to $($url), body length $($body.Length), timeout $($script:XymonSettings.serverHttpTimeoutMs)ms"
And then this one (with a timeout exception):
" Exception connecting to $($url):`n$($_)"
And not either of these:
" FAILED, HTTP response code: $($response.StatusCode) ($statusCode)"
or
" Received $($output.Length) bytes from server"

I may have spoken too soon. It's indeed working on box1, but when I edited the xymonclient_config.xml on box2 and re-entered the password so box2 would re-encrypt it for it's connection to the server, it's timing out. Does each client need it's own individual user/pass? That seems unnecessary. I just tried different credentials and it still timed out. The difference between box1 and box2 is the OS. They're on the same network and can both reach the server via https so I don't think it's a networking issue. box1 = Windows 10 Pro box2 = Windows Server 2008 R2 Enterprise
Apache logs show nothing unusual. I've looked at all the logs I can find on the server but I'm not seeing anything that would tip me off as to the issue. Ideas?

It's confirmed working great on Windows Server 2012, but not 2008. Can you point me in a direction to look for a solution to the cipher issues? I'm not going to reduce things to port 80, I want to keep things on 443.

All xymoncgimsg.cgi does as far as I can tell is relay the message(s) received over HTTPS via TCP to localhost port 1984 (which is what the man page says as well). So you need that listening (which by default it will be). I don’t recall making any other config changes to make this work (aside from Apache etc to sort out the authentication). I suspect the time out is waiting for the response – when you submit data to Xymon, you normally get the client local config back from the server. This comes back via the HTTPS response. There is a timeout setting – sorry I forgot to document it in the table in the Word doc – serverHttpTimeoutMs – which defaults to 100000 milliseconds – i.e. 100 seconds. This is the time it waits for the response from the server. 100 seconds is pretty generous unless you’re traversing particularly slow VPNs or saturated connections. You can override this in the xymonclient_config.xml file. I’m assuming you’re getting this message: " Connecting to $($url), body length $($body.Length), timeout $($script:XymonSettings.serverHttpTimeoutMs)ms" And then this one (with a timeout exception): " Exception connecting to $($url):`n$($_)" And not either of these: " FAILED, HTTP response code: $($response.StatusCode) ($statusCode)" or " Received $($output.Length) bytes from server" Zak *From:*Xymon <xymon-bounces at xymon.com> <mailto:xymon-bounces at xymon.com> *On Behalf Of *kspringer at innovateteam.com <mailto:kspringer at innovateteam.com> *Sent:* Thursday, 8 November 2018 08:51 *To:* Xymon MailingList <xymon at xymon.com> <mailto:xymon at xymon.com> *Subject:* [External] Re: [Xymon] PSclient sending from intranet Anyone have xymoncgimsg.cgi functioning on their server and successfully receiving PSclient data over HTTPS?

The Xymon client will prefix the encrypted password with ‘{SecureString}’, so it is easy to tell if the client has attempted to encrypt the password or not. This is done using the .NET SecureString functions, which means that the encryption is unique to the server and user. This means that once the password has been encrypted, you cannot use the same xymonclient_config.xml on another server. It also means that if you have been testing by running XymonPSClient from a command prompt, and this encrypts the password, when you run XymonPSClient as a service it will not be able to decrypt the password unless the service is running as the same user. In both scenarios, replacing the encrypted password with the plain text password and re-starting Xymon will cause the password to be re-encypted.

Thanks for the info. I check the cipher/protocols on the 2008 box and they're all the defaults. I've enabled the latest that match what my Xymon server is configured with and now I'm just waiting until after hours to reboot my box and hope it connects.

Hi
Just to confirm, you can use the same username / password across multiple servers and I see you are using the correct process of re-editing the config file for different servers.
As mentioned by Timothy, on the Win 2008 server, you need to make sure the client SCHANNEL settings are correct (not the server ones) – they should be under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols.
Pretty sure your Apache TLS settings will be OK as the other server is working.
Good luck 🙂

Thanks for the info. I check the cipher/protocols on the 2008 box and they're all the defaults. I've enabled the latest that match what my Xymon server is configured with and now I'm just waiting until after hours to reboot my box and hope it connects.

You may have to check Apache settings to see what ciphers and/or protocols are enabled on that end.

It's indeed working on box1, but when I edited the xymonclient_config.xml on box2 and re-entered the password so box2 would re-encrypt it for it's connection to the server, it's timing out. Does each client need it's own individual user/pass? That seems unnecessary. I just tried different credentials and it still timed out. The difference between box1 and box2 is the OS. They're on the same network and can both reach the server via https so I don't think it's a networking issue. box1 = Windows 10 Pro box2 = Windows Server 2008 R2 Enterprise
Apache logs show nothing unusual. I've looked at all the logs I can find on the server but I'm not seeing anything that would tip me off as to the issue. Ideas?

Yes, I have it working. As you say, the URL needs to include the full path to xymoncgimsg.cgi.
All xymoncgimsg.cgi does as far as I can tell is relay the message(s) received over HTTPS via TCP to localhost port 1984 (which is what the man page says as well). So you need that listening (which by default it will be).
I don’t recall making any other config changes to make this work (aside from Apache etc to sort out the authentication).
I suspect the time out is waiting for the response – when you submit data to Xymon, you normally get the client local config back from the server. This comes back via the HTTPS response. There is a timeout setting – sorry I forgot to document it in the table in the Word doc – serverHttpTimeoutMs – which defaults to 100000 milliseconds – i.e. 100 seconds. This is the time it waits for the response from the server. 100 seconds is pretty generous unless you’re traversing particularly slow VPNs or saturated connections. You can override this in the xymonclient_config.xml file.
I’m assuming you’re getting this message:
" Connecting to $($url), body length $($body.Length), timeout $($script:XymonSettings.serverHttpTimeoutMs)ms"And then this one (with a timeout exception):
" Exception connecting to $($url):`n$($_)"And not either of these:
" FAILED, HTTP response code: $($response.StatusCode) ($statusCode)"or " Received $($output.Length) bytes from server"

Anyone have xymoncgimsg.cgi functioning on their server and successfully receiving PSclient data over HTTPS? The documentation for this is vague and doesn't specify how to make it work. Any specifics would be greatly appreciated.
Thanks, Kris Springer

HTTP is an alternate method. It can be used if you have xymoncgimsg.cgi running on the web server on your Xymon server – see https://www.xymon.com/help/manpages/man8/xymoncgimsg.cgi.8.html<https://urldefense.proofpoint.com/v2/url?u=https-3A__www.xymon.com_help_manpages_man8_xymoncgimsg.cgi.8.html&d=DwMGaQ&c=eIGjsITfXP_y-DLLX0uEHXJvU8nOHrUK8IrwNKOtkVU&r=S-aLwpx-PHBTBMIG_c2JczRC0SfuZCmsiH9Iams25FI&m=-OwMT0n637myRsiGrh2Ey_FyOjBckX9cnzeXB9ID_dw&s=nwg-TdqZw8dbasxkybIMrt8HKpuV-U4Z2HpC5Rbr1BM&e=>. The web server running the CGI can be configured for SSL (i.e. HTTPS) and / or authentication – XymonPSClient supports basic authentication and SSL. If you require authentication, the <serverHttpUsername> and <serverHttpPassword> elements should be configured. If you are using HTTP and transmitting over unsecure networks (e.g. the internet), it is strongly recommended to enable SSL, authentication and disallow HTTP connections.
ServerHttpPassword encryption If <serverHttpPassword> is set, the Xymon client will encrypt the password if it is not encrypted and remove the plain text password from the configuration file, overwriting with the encrypted password. The Xymon client will prefix the encrypted password with ‘{SecureString}’, so it is easy to tell if the client has attempted to encrypt the password or not. This is done using the .NET SecureString functions, which means that the encryption is unique to the server and user. This means that once the password has been encrypted, you cannot use the same xymonclient_config.xml on another server. It also means that if you have been testing by running XymonPSClient from a command prompt, and this encrypts the password, when you run XymonPSClient as a service it will not be able to decrypt the password unless the service is running as the same user. In both scenarios, replacing the encrypted password with the plain text password and re-starting Xymon will cause the password to be re-encypted.

Anyone have an idea about how to collect client server stats using the Powershell client on machines that are on an intranet that blocks port 1984, and send it out to our external xymon server located in a different part of the country? The intranet network doesn't want to open any additional ports to allow the traffic out.
