Wormly & Xymon

Just a quick one. Does anybody know whether or not the Wormly service www.wormly.com uses Xymon? I've noticed that Wormly uses BBWin as a monitoring agent: https://www.google.co.uk/search?q=bbwin+wormly Cheers, Chris

Strange Alerts
by john＠executech.com 25 Jul '17

25 Jul '17

I'm getting an extremely strange behavior with alerts. Several recipients are complaining that they are getting alerts for servers that they don't manage and aren't assigned. There are about 200 lines in my alerts.cfg file. I've verified that the alert rules are accurate and running the test alert script (./bin/xymoncmd xymond_alert --test sever.name cpu) shows the correct, assigned user and the info page for the servers show the right user's email. Anyone know what I'm missing? The same problems happened with my old Hobbit server as well so it could be a config file issue but I've looked thoroughly and haven't been able to track it down yet.

xymon with tls1.2
by ve2cii＠canasoft.net 24 Jul '17

Hi, Finally, I have succeeded at building the xymon against an updated opessl. root at dns8:~# openssl version OpenSSL 1.0.2h 3 May 2016 root at dns8:/home/xymon_test/server/bin# ./xymonnet --version xymonnet version 4.3.27 SSL library : OpenSSL 1.0.2h 3 May 2016 The way I did it was to replace the system openssl with openssl-1.0.2h. I used the system tools to repackage a slackware-14.2 package to slackware-12.1 package. Then I completely deleted the xymon build and untarred it fresh. Then I got proper results. Thank you all for the help, and I am testing. -- sysadm cronomagic.com/gemstelecom.com e-mail ve2cii at canasoft.net POWERED BY LINUX

FYI the package over at Terabithia works with TLS 1.2 out of the box. I have an httpd that is TLS 1.2 only. http://terabithia.org/rpms/xymon/ Josh Luthman Office: 937-552-2340 Direct: 937-552-2343 1100 Wayne St Suite 1337 Troy, OH 45373 On Fri, Jul 21, 2017 at 10:41 AM, Henrik Størner via Xymon <xymon at xymon.com> wrote: > _______________________________________________ > Xymon mailing list > Xymon at xymon.com > http://lists.xymon.com/mailman/listinfo/xymon > > > ---------- Forwarded message ---------- > From: "Henrik Størner" <henrik at hswn.dk> > To: Xymon mailinglist <xymon at xymon.com> > Cc: > Bcc: > Date: Fri, 21 Jul 2017 16:41:50 +0200 > Subject: Re: [Xymon] xymon with tls1.2 > Hi Frank, > > what happens if you leave out the --ssllib and --sslinclude parameters?

xymon with tls1.2

Hi, This did not work. It still uses the default system openssl. Hi Frank, what happens if you leave out the --ssllib and --sslinclude parameters? It is an unusual location for OpenSSL to be installed, so I guess you compiled it yourself? It also ought to pull in libdl.so automatically, but that probably requires some magic when compiling OpenSSL. Anyway, I believe you can work around it by setting NETLIBS in xymon-4.3.27/build/Makefile.Linux like NETLIBS="-ldl" On 7/21/17 10:41, Henrik Størner via Xymon wrote: > Hi Frank, > > what happens if you leave out the --ssllib and --sslinclude > parameters?

Hi, I have removed the openssl that goes with the linux. That broke a bunch of stuff. So I had to put it back for now till I compile apache etc against the new ssl libraries. For now I am concentrating on xymon. The way it is xymon is "insisting" on using the old default ssl libraries. Hi Frank, what happens if you leave out the --ssllib and --sslinclude parameters? It is an unusual location for OpenSSL to be installed, so I guess you compiled it yourself? It also ought to pull in libdl.so automatically, but that probably requires some magic when compiling OpenSSL.

I am re-sending this from my member account. Hi everyone, We are changing all our SSL web sites on windows over to tls1.2. So I have upgraded the openssl on the xymon server.

NSSM & Xymon PowerShell Client
by christopherrowson＠gmail.com 18 Jul '17

18 Jul '17

Hi list, I've been asked to look at a Xymon install which needs updating. The first thing I noticed was that the monitored Windows servers in the environment are using the old BBWin client which doesn't seem to be maintained any longer. Checking the mailing list I've noticed that a lot of people are now using the WinPSClient so I've been trying to familiarise myself with it. As I hadn't come across the software before, I ran the source for NSSM (the manager which runs the PS script as a service) past a C++ code analysis tool and it came out with a few /potential/ issues. The critical and high vulnerabilities are: Critical: Use of memmove Allows Buffer Overflow ------------------------------------------------------- - The size limit is larger than the destination buffer, while the source is a char* and so, could allow a buffer overflow to take place. - nssm-master\io.cpp Line 213 High: LoadLibrary ------------------ - The function searches several paths for a library if called with a filename, but no path. This can allow trojan DLLs to be deployed, regardless of the presence of the correct DLL. Manually check the code to ensure that the full path is specified. - nssm-master\imports.cpp Line 15 I'm not a C++ programmer, but looking at the code, the findings of the analysis tool look at least possible. Has anybody else performed code scrutiny against this aspect of the solution who can confirm or deny any issues? I also wondered if there's any particular reason why the PowerShell script can't be run at intervals by task scheduler instead of running as a service? Thanks, Chris

Xymon on Centos7 and migrate history and rrd from old Xymon
by chrisp＠lightstoneauto.co.za 17 Jul '17

17 Jul '17

Good day My current Xymon still runs on a now unsupported centos5 server. I am prepping a Centos7 server for my new xymon instance 1 - I found the xymon repo, please refer to https://centos.jordy.eu/centos-test/ Is this a trusted repository to use? 2 - Is there a guide available that I can follow to migrate xymon configs, history data and rrd data to the new server?
