Obscure Scripts

A collection of scripts from The Obscure Organization - a public access UNIX system in continuous use since 1995.

• blockip.sh - Use iptables to temporarily block an IP addreess or CIDR block
• cloud-init-centos-7-ipv6.yml - Use in instance data for CentOS 7.x EC2 servers that are having trouble getting an IPv6 default route. See also cloud-init-centos-7.6-ipv4-ena.yml and cloud-init-centos-7.6-ipv6-ena.yml
• icinga2-graceful.sh - Check the validity of icinga2 system configuration files, then restart it only if the configuration is ok.
• icinga2-watchdog.sh - Ensure that an icinga2 system alerts once per day to let people know it is still alive - and where to complain if it is dead.
• imapd-reap-processes.sh - Kill off stale imapd processes that accumulate on a busy mail server
• patronus.sh - kill login sessions and processes on other ttys, with a whimsical Harry Potter twist. This might be one of the only works of fan fiction parody written in bash!. Originally released under the GPLv3, now relicensed under the MIT license, and updated to be shellcheck clean.
• run-sysbench.sh - Run sysbench with a standard set of options. Useful for collecting the same set of performance statistics on multiple hosts.
• ssh-add-all.sh - Alias to add all your SSH keys from $HOME/.ssh/ with one command.
• ssh-add-ramdisk.sh - Keep your SSH keys on a USB key, but load them into a RAMDisk on macOS or Linux - so you don't have to keep permanent copies of the SSH keys on the systems you physically use, which is useful sometimes.
• ssh-env.sh - Use to help reconnect managed terminal sessions (think screen or tmux) terminals to your SSH key agent via environment manipulation.
• uptimerobot-firewall-update.sh - Update firewall entries that allow uptimerobot.com to check otherwise resticted services. Uptime Robot is free and is suitable for small-scale monitoring as a primary service or as a secondary monitor that watches your primary monitoring system and most critical services.
• tiamat-setup.sh - Set up packages and more on tiamat.obscure.org (emergency recovery script)
• watch-filevault-setup.sh - Watch and log the filevault encryption process, which can take a really long time on an older Macintosh.
