Can XYMSRV be a fqdn/hostname not an IP
by didds3＠yahoo.co.uk 13 Feb '24

simple question...? as time marches on etc has xymon/hobbit reached a stage yet when XYMSRV can be set to a hostname rather than an IP address? eg? rather than XYMSRV = "10.10.10.10" we could have XYMSRV = "xymonhost" where "xymonhost" resolves in dns to 10.10.10.10? This would be a huge benefit where anytime a xymon server is migrated to another system eg underling EOL OS, one wouldn't have to go around changing every single client server's xymon configs to a new Ip...? all that would be required is a reset in an appropriate dns zonefile so dns just provides the new IP after the TTL passes etc. ??? cheers ian

Patch: ntpdate option -p deprecated
by roland＠spinnaker.de 13 Feb '24

Hi! In Debian ntpdate from ntpsec package throws a warning that "-p is no longer supported". So it may be a good idea to remove the "-p 1" from NTPDATEOPTS="-u -q -p 1" # Standard options to ntpdate in xymond/etcfiles/xymonserver.cfg.DIST. The attached patch solves this issue. Greetings Roland

Patch: PCRE2 support
by roland＠spinnaker.de 12 Feb '24

Hi! In https://bugs.debian.org/999921 Yavor Doganov provided a patch to convert xymon from outdated pcre3 to pcre2. Since I didn't see this patch here on the list, I'll forward it here. Currently it's against 4.3.30, but Yavor offered to rebase it on 4.4-alpha. It would be great if you could get rid of pcre3. Greetings Roland

Patch: Regenerating HTML man pages
by roland＠spinnaker.de 11 Feb '24

11 Feb '24

Hi, while building the Debian package of xymon I noticed two issues with re-generating the HTML man pages: a) Generating the man pages places the current day in the header, so the files cannot be generated reproducible (see https://en.wikipedia.org/wiki/Reproducible_builds) Using SOURCE_DATE_EPOCH (if it is set) solves this problem. b) Without "-H localhost" as parameter of man2html the generated HTML files differ from what is packaged in the tarball. So I added this option. The attached patch implements these two cases. Greetings Roland

Patch: Fix reading service banners from TLS-1.3-enabled hosts
by roland＠spinnaker.de 11 Feb '24

Hi, Andreas Oberritter analyzed and fixed the well known and often discussed issue with pop3s/imaps flapping in combination with TLS 1.3. See https://bugs.debian.org/930532 and https://salsa.debian.org/debian/xymon/-/merge_requests/1 I use this patch for many months now without any issues, so I'd like to see it applied in the official code. His patch is appended to this mail. Greetings Roland

Patch: report.sh and snapshot.sh fix for Firefox
by roland＠spinnaker.de 09 Feb '24

09 Feb '24

Hi! I noticed, that in Xymon 4.3.30 opening the "Snapshot Report" (snapshot.sh) as well as the "Availability Report" (report.sh) in the "Reports" menu do not work as expected, but try to download a file snapshot.sh or report.sh. Digging deeper into this, I noticed, that this seems a Firefox only problem, while chromium works without problems. In the code web/snapshot.c and web/report.c I found a variable usemultipart, which is 1 by default and is reset to 0 if HTTP_USER_AGENT contains "KHTML", which (according to a comment) cannot handle multipart documents. It seems, that current Firefox also can not handle this correct, while Chromium uses the User-Agent "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.212 Safari/537.36" so it already disables multipart.

ubuntu client tests data apt and libs
by dito74＠gmail.com 01 Feb '24

Hello everyone, I am looking for answers for these tests that I am not sure how to resume. I had an Ubuntu server running xymon and also running the client to report to itself, probably an old version of Ubuntu, I want to say 18.xx and probably the last 32 bit around. I've finally upgraded to a better hardware, I now have the latest Ubuntu 22, I've migrated all my configs, xymon client and server, and other services like nginx, that I was running on there. Same hostname, same IP, so nothing was changed beside the OS, All good so far, but I have a non issue request, just a curiosity at this point that I cannot find an answer to. It's about tests that were there before and now they are no longer there, so they are purple on the display page. The older server was reporting 2 tests that I presumed came from the xymon client "apt" and "libs". Those tests are no longer reporting, Where did they come from? And can I resume them on the new server? Thank you all in advance. Gab
