Fu10 Night Crawling 17 18 19 Tor Install -

Edit /etc/tor/torrc (or torrc in your install folder):

SocksPort 9050
SocksPolicy accept 127.0.0.1
Log notice file /var/log/tor/notices.log
# Increase circuit lifetime for longer crawls
MaxCircuitDirtiness 600
NumEntryGuards 8
CircuitBuildTimeout 60

Restart Tor after changes.

If your SIEM or IDS captures a packet with the signature fu10 night crawling 17 18 19 tor install, treat it as an active reconnaissance indicator. Here is how to defend against this specific methodology.

The crawler initiates a TCP SYN scan through the Tor proxy chain. Because Tor adds latency, scanning is slow—often 100 packets per second max. This is by design. "Night crawling" scripts log only open ports plus banner grabs. fu10 night crawling 17 18 19 tor install

Example simulated output:

[03:14:17] Target: 192.168.1.104:17 - OPEN (QOTD: "Welcome to legacy server")
[03:14:19] Target: 192.168.1.104:19 - OPEN (CHARGEN: character generation active)
[03:15:42] Target: 10.0.0.56:18 - OPEN (MSP: No authentication required)

To expose the Tor SOCKS port to the LAN (if desired), update firewall rules cautiously.

OpenWrt (uci):

uci add firewall rule
uci set firewall.@rule[-1].src='lan'
uci set firewall.@rule[-1].dest_port='9050'
uci set firewall.@rule[-1].proto='tcp'
uci set firewall.@rule[-1].target='ACCEPT'
uci commit firewall
/etc/init.d/firewall restart

Debian (iptables/nft): Example iptables to allow lan subnet to reach SOCKS:

iptables -A INPUT -p tcp -s 192.168.1.0/24 --dport 9050 -j ACCEPT

Persist rules with your distro's preferred method.

If routing all traffic through Tor (transparent proxy), additional configuration is required: enable Tor's TransPort and DNSPort in torrc, and apply NAT rules to redirect traffic. This setup is advanced and may break DNS and UDP-based protocols; consult Tor Project docs before proceeding. Edit /etc/tor/torrc (or torrc in your install folder):

Example torrc additions for transparent proxy:

TransPort 9040
DNSPort 5353
VirtualAddrNetworkIPv4 10.192.0.0/10
AutomapHostsOnResolve 1

Example iptables (simple illustration):

iptables -t nat -A PREROUTING -i br-lan -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 9040
iptables -t nat -A PREROUTING -i br-lan -p tcp -m tcp --dport 443 -j REDIRECT --to-ports 9040

Do not redirect DNS or leak local host traffic; test carefully. Restart Tor after changes
