hongkongkiwi / import-blacklist-categories.sh
Last active February 3, 2016 07:51
This is a simple script to import many (millions!) of entries from a blacklist file into redis. It first generates the file using redis mass import format, then it pipes that into redis for super fast importing.
#!/bin/bash
FILE="CATEGORIES"
REDIS_KEY="categories"
while read line; do
category=`echo "$line" | cut -f1 -d'-'`
description=`echo "$line" | cut -f2 -d'-'`
redis-cli hset "$REDIS_KEY" "$category" "$description"
done < "$FILE"

hongkongkiwi / open-port-test
Created February 8, 2016 09:45
Simple bash script to test whether a port is open or closed. It's a good alternative to telnet.
#!/bin/ash
NETCAT="netcat"
if [[ "$2" == "" || "$1" == "" ]]; then
echo "Invalid port or ip!"
echo "USAGE: $0 ip port"
exit 0
fi

hongkongkiwi / firewall-start
Last active April 22, 2023 13:52
Bash script to allow some ports on Asus routers running Merlin firmware. This should be put in your /jffs/scripts and made executable (chmod +x /jffs/scripts/firewall-start). Now handles duplicate rules (it won't add again) and inserting before any final DROP in the INPUT chain. Quite useful ;)
#!/bin/sh
DEBUG="NO"
LOGGER_NAME="firewall"
PORTS="tcp:9443"
WAN="$1"
log() {
if [ "$DEBUG" == "YES" ]; then
echo "$1"

hongkongkiwi / shadowsocks-ddns
Last active April 25, 2018 11:25
A wrapper script to setup shadowsocks using a ddns host. This sort of requires that your domain is reachable using the non-relayed DNS servers.
#!/bin/bash
USAGE="USAGE: $0 server config.json"
SERVER="$1"
CONFIG="$2"
PID_DIR="/var/run"
SS_LOCAL_PID="$PID_DIR/ss-local.pid"
SS_TUNNEL_PID="$PID_DIR/ss-tunnel.pid"
DNS_FORWARD_REMOTE="8.8.8.8:53"

hongkongkiwi / generate-ssh-key
Last active December 18, 2023 07:45
Simple one liner to generate an SSH key without a password in the default place with the comment as hostname then print out the public key for copy and paste.
HOSTNAME=`hostname` ssh-keygen -t rsa -C "$HOSTNAME" -f "$HOME/.ssh/id_rsa" -P "" && cat ~/.ssh/id_rsa.pub
