fingerprint reader on C-7 ???
by Fred Smith 03 Nov '18

03 Nov '18

Hi all! I just got a new (to me) used laptop (HP EliteBook 8530p) and find that it has a fingerprint reader. Wondering if it could be made to work for me (Centos-7) I did a lot of googling (well, actually duck-duck-go-ing) and found a ton of hits on either setting it up in Windoze, or others wondering if it can be used in Linux. Some info on setting it up in Ubuntu, and a couple of pages on setting it up in Fedora, pages that were ten years old, or so. Found an academic paper on a group that wrote portable tools in Java that allegedly enable it in a cross-platfor manner, but not the software itself. Does anyone here have any better information on if it is possible, and if so, how? thanks in advance!

PostgreSQL port accessible even though it should be blocked by firewall

Hi, this puzzles me: On one of our developer workstations, all ports with the exception of SSH are closed: $ firewall-cmd --list-all public (active) target: default icmp-block-inversion: no interfaces: eno1 sources: services: ssh dhcpv6-client ports: 22/tcp protocols: masquerade: no forward-ports: source-ports: icmp-blocks: rich rules: $ but still port 5432/tcp (PostgreSQL) is open: $ nmap -P0 devel-host Starting Nmap 6.40 ( http://nmap.org ) at 2018-10-29 19:46 CET Nmap scan report for devel-host (xxx.xxx.xxx.xxx) Host is up (0.94s latency). rDNS record for xxx.xxx.xxx.xxx: devel-host.our.domain Not shown: 998 filtered ports PORT STATE SERVICE 22/tcp open ssh 5432/tcp open postgresql Nmap done: 1 IP address (1 host up) scanned in 57.26 seconds $ PostgreSQL is running in a docker container: $ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 6f11fc41d2f0 postgres "docker-entrypoint..." 4 days ago Up 4 days 0.0.0.0:5432->5432/tcp postgres $ The various docker interfaces and virtual bridges are not assigned to any specific zone. Why is port 5432/tcp open? frank
