Ken JohnsonI work as an independent consultant performing system and small network administration, and writing specialized technical documentation. I have used Wireshark and other tools for network packet capture and analysis for problem-solving since 1979. I am new-ish to Linux Mint, but have set up other Linux workstations since about 1998. I use fail2ban on a client's mail server (exim4, dovecot, Debian stable) to drop 25 - 200 hostile packets/hour. I use fail2ban on a client's webserver to stop OpenVAS and other pests. I run a mail server for a client using Debian Linux, exim4, dovecot, spamassassin, fail2ban, ipset, and iptables.
