Issue with NOCOLUMNS in default section of hosts.cfg

This is doubtless a completely STUPID question. Have been using Xymon since BB, then Hobbit days...recently upgraded to 4.3.30 and moved/replaced the main host it was running on. To the point, I have everything working, but... on the main display, I have getting columns for "files" and "ports". More to the point, previously this worked. I have an entry at the TOP of the hosts.cfg file that looks like this: # hosts.cfg file .default. NOCOLUMNS:ports,files 199.33.251.50 joshua.judahnet.net # conn dns ntp bbd smtp ssh 199.33.251.52 ezekiel.judahnet.net # conn dns ntp smtp ssh And it worked.. I have tried changing that line to .default. #NOCOLUMNS:ports,files OR 0.0.0.0. .default. #NOCOLUMNS:ports,files OR 0.0.0.0. .default. NOCOLUMNS:ports,files None of them work... I can append on the END of all the individual HOSTS lines "NOCOLUMNS:ports,files"... and that works... What am I doing wrong with default section ? Jim

Monitoring websites using TLS1.3

Sorry, I should have published my revised hosts.cfg line: 0.0.0.0 Website # noconn sni https://www.website.com/ I now get a green status, an ?HTTP/1.1 200 OK? response ? and the certificate info too: SSL certificate for https://www.website.com/ expires in nnn days Server certificate: <data removed> Cipher used: TLS_AES_256_GCM_SHA384 (256 bits) Thanks for your help, Matt. Kind regards Martin

Monitoring websites using TLS1.3
by martin＠savcom.co.uk 25 Mar '20

25 Mar '20

I'm trying to monitor a website that is operated on part of Cloudflare's setup and I am failing to get a positive result. The website uses TLS1.3 and Xymonnet tells me that it was built USING OpenSSL v 1.1.0g (Xymon version 4.3.28) which only handles TLS variants 1.0, 1.1, and 1.2. I'm monitoring the server using the hosts.cfg entry: 0.0.0.0 Website # noconn nosslcert https3://www.website.com/ I've tried other httpsX variants and no joy. The result I get from the website test is the rather sparse "- SSL error" Digging into Xymonnet gives a more cryptic Unspecified SSL error in SSL_connect to https (47873/tcp) on host xx.xx.xx.xx: error:14094410:SSL routines:ssl3_read_bytes:sslv3 alert handshake failure I'm assuming the issue is around the version of OpenSSL, as the OpenSSL v1.1.1 beta version manages TLS1.3 whereas OpenSSL v1.1.0g does not. I have three questions: - Is there a way of setting Xymon up to manage this monitoring? - When is it planned to include OpenSSL v1.1.1 in a Xymon build? - In the meantime, is it worth writing a simple script to test the HTTPS response I need and feed this to Xymon separately? Many thanks Martin Davies

email add-on other than html_mail.pl?
by christian.becker＠rhein-zeitung.net 24 Mar '20

24 Mar '20

Hello to the list, i'm looking for another email add-on to Xymon (or another script) other than html_mail.pl which I'm currently using. The html_mail.pl works fine, but now I'm in the situation to send emails to a MS Teams subchannel, and the result is useless, because it's totally mis-formatted in MS Teams. I tried using the Xymon built-in mail function without html_mail.pl, but this is also not really nice, I'ld like to have at least the red / yellow / green icons together with a black background. My knowledge isn't good enough to modify html_mail.pl to my needs. Any idea? Stay at home - stay healthy! Best regards from Germany Christian

xymon

Hi, I have installed on Linux redhat 7.7 xymon server. But I am getting error with ssl and I do not know how to go forward. I spent 2 days to try to solve this problem, I am new linux admin, and I want to use xymon for monitoring. Can you give me some hints&tips ? thank you, Checking for C-ARES library ... Compiling with c-ares library works OK C-ARES version: Found 1.10.0 - OK, require 1.5.1 Linking with c-ares library works OK Checking for RRDtool ... Not RRDtool 1.0.x, checking for 1.2.x Compiling with RRDtool works OK Linking with RRDtool works OK *Checking for OpenSSL ...Compiling with SSL library works OK/usr/bin/ld: cannot find -ltirpccollect2: error: ld returned 1 exit statusmake: *** [test-link] Error 1Warning: Cannot link with SSL libraryOpenSSL include- or library-files not found.* Although you can use Xymon without OpenSSL, you will not be able to run network tests of SSL-enabled services, e.g. https. So installing OpenSSL is recommended. OpenSSL can be found at http://www.openssl.org/ If you have OpenSSL installed, use the "--sslinclude DIR" and "--ssllib DIR" options to configure to specify where they are.

Why are my emails to the list showing up as attachments? This is happening even if I send plain-text emails. Unfortunately, we use Office 365. Is there any setting I can tweak to fix this? Thanks, g

relay server
by dmallor＠gmail.com 19 Mar '20

19 Mar '20

Is there a way to create a xymon relay service.. As example my xymon server cannot reach the end point to perform tests (e.g http, dns, etc or receiving local client data) but an intermediate device could do it. Not sure if this is something a client or server could do? xymonserver(main) <> xymonserver(relay) <> xymonclient thx in advance Danny
