Hello,
I recently installed Fail2Ban along with nginx using the linuxserver/letsencrpt docker. I love it. It has solved a long term problem for me and made my network run much smoother. I have ironed out all my install problems but one, which has been driving me crazy. In jail.local, I use action = %(action_mwl)s as my default action and after tailoring e-mail notification settings in sendmail-whois-lines.local with Fail2Ban" ) | /usr/sbin/sendmail -t -v -H 'exec openssl s_client -quiet -tls1 -starttls smtp -connect smtp.gmail.com:587' -aumyusername -apmyapppassword <dest> it works great except for one issue. I believe the default action uses sendmail-whois-lines.conf This is what I always get in the response: [Querying whois.iana.org:43 '122.166.7.73'] [Querying whois.iana.org:43 'domain 122.166.7.73'] [whois.iana.org] % IANA WHOIS server % for more information on IANA, visit http://www.iana.org % % Error: Invalid query domain 122.166.7.73 In an effort to figure things out, I have tried 1. /usr/bin/whois 107.33.23.17 which is successful 2. sudo docker exec -it letsencrypt whois google.com which is successful 3. sudo docker exec -it letsencrypt whois 122.166.7.73 which fails with the above error message. I am relatively new to docker, but here is my docker-compose: version: "2" services: letsencrypt: # https://github.com/linuxserver/docker-letsencrypt container_name: letsencrypt image: linuxserver/letsencrypt:latest restart: unless-stopped cap_add: - NET_ADMIN volumes: - /home/user/docker/letsencrypt/config:/config - /etc/localtime:/etc/localtime:ro environment: - PGID=xxxx - PUID=xxxx - EMAIL=my_em...@gmail.com - URL=myduckdns.duckdns.org - SUBDOMAINS=wildcard - VALIDATION=duckdns - TZ=America/New_york - DUCKDNSTOKEN=myxxxxxduckdnsxxxxxtoken ports: - "80:80" - "443:443" Any help would be greatly appreciated. Thanks, Dan
