logging facility in Synopse seems to be an interesting alternative to JclDebug. Need to check out how they differ in looking up the method name for tracing.

On my todo list, as Synops is updated more often than JCL: [WayBack] The logging facility in Synopse seems to be an interesting alternative to JclDebug: According to this StackOverflow answer, one of its features is looki… – Thomas Mueller (dummzeuch) – Google+

GitHub – gamelinux/passivedns: A network sniffer that logs all DNS server replies for use in a passive DNS setup

Posted by jpluimers on 2020/07/15

Cool tool: [WayBackGitHub – gamelinux/passivedns: A network sniffer that logs all DNS server replies for use in a passive DNS setup via [WayBack] How to log all my DNS queries? – Unix & Linux Stack Exchange (thanks mxmlnkn!).

It listens on port 53 for DNS requests then logs them to a file on regular intervals aggregating similar requests.

Usage is simple:

# passivedns -i ens32 -l /var/log/passivedns.log

[*] PassiveDNS 1.2.0
[*] By Edward Bjarte Fjellskål <>
[*] Using libpcap version 1.8.1
[*] Using ldns version 1.7.0
[*] Device: ens32
[*] Sniffing...

There are more options in the docs (it can do a lot including export to databases for querying), but this simple one allows you to just grep over abusive hosts like [WayBack] Nice when someone in Dallas using is querying your DNS infrastructure for many permutations of domains… · GitHub

Originating in 2013 ([WayBack] PassiveDNS version 1.0 | GameLinux), it still is being maintained.

It uses libpcap for sniffing and I ran it on separate machine hooked to a vSwitch configured in promiscuous mode so it sees all network traffic from that particular network segment.

There is a not fully up-to-date package available for various OpenSuSE releases (including Tumbleweed) [WayBack] Install package home:mnhauke:security / passivedns. It is x86_64 only, so if you want to run it on ARM, or want a more recent version then you need to build it yourself, for instance by using this as a template: [WayBack] Show home:mnhauke:security / passivedns – openSUSE Build Service.

Next tool on my list to try: [WayBack] dnstracer(8) – Linux man page.
